Kim DG, Lee DY, Woo SJ, Park KH, Park SJ. Nationwide incidence of congenital and infantile cataract requiring surgery in Korea. Sci Rep 2024; 14:5251. [PMID: 38438402 PMCID: PMC10912700 DOI: 10.1038/s41598-024-53339-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Accepted: 01/31/2024] [Indexed: 03/06/2024] Open
Abstract
Congenital and infantile (CI) cataract is one of the most important and preventable cause of blindness in children, but the incidence has not been studied in Korea. We collected data from the national claims database of the National Health Insurance Service of Korea from 2002 through 2019. We identified children who underwent cataract surgery within the age of 5 years, and cumulative incidence rates were calculated for each of the three age criteria. 989 patients out of 4,221,459 births underwent surgery with CI cataract during the period. The cumulative incidence rates per 10,000 births were 1.60 (0-1 years), 2.38 (0-3 years), and 2.95 (0-5 years), respectively. The incidence peaked in the 2007 birth cohort, which coincides with the start of the national screening program for infants/children. Primary intraocular lens implantation was performed in 439 patients (44%). Strabismus and glaucoma requiring surgery occurred in 291 patients (29.4%) and 32 patients (3.2%), respectively, within 8 years after cataract surgery. The incidence rates of CI cataract in Korea appear to be comparable to previous studies in other regions. The early screening program for infants may reduce delayed diagnosis and increase the proportion of patients undergoing surgery at a critical time for visual development.

Sukhija J, Kaur S, Korla S, Kumari K. Surgical challenges of posterior optic capture in pediatric cataract surgery. Indian J Ophthalmol 2024; 72:51-55. [PMID: 38131569 PMCID: PMC10841806 DOI: 10.4103/ijo.ijo_506_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2023] [Revised: 06/19/2023] [Accepted: 07/17/2023] [Indexed: 12/23/2023] Open
Abstract
PURPOSE The efficacy of posterior optic capture (POC) in reducing posterior capsule opacification (PCO) in pediatric cataract is well recognized. The purpose of this paper was to identify the surgical challenges when attempting this technique and highlight the etiquettes to follow when performing this maneuver. METHODS Prospective observational noncomparative case series. Children diagnosed with congenital or developmental cataracts undergoing cataract surgery and primary IOL implantation with posterior optic capture (and no anterior vitrectomy) from June 2017 to April 2022 at a tertiary care referral institute were included. Records of all intraoperative findings and postoperative complications until the last follow-up were noted. RESULTS Posterior optic capture was attempted in 53 eyes of 49 children aged 2.4 ± 1.98 years. The mean follow-up of the patients was 16.5 ± 14.2 months (range 6 months-5 years). Successful POC could be performed in 46 eyes (86.8%). Two eyes developed posterior capsular opacification at the last follow-up. In eyes where POC could not be performed, five of these (83%) were children below 12 months of age with half of them having a preexisting posterior capsular defect. CONCLUSION Posterior optic capture is technically challenging with a steep learning curve that can be mastered over time. Adequate relative sizing of the anterior and posterior capsulorhexis is important. Caution is advised when using this technique in infants and in cases with posterior capsular defects.

Risk of visual axis opacification in infants with and without primary IOL implantation after congenital cataract surgery performed during the first 4 months of age. Graefes Arch Clin Exp Ophthalmol 2023; 261:3643-3649. [PMID: 37329362 PMCID: PMC10667373 DOI: 10.1007/s00417-023-06143-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Revised: 06/04/2023] [Accepted: 06/06/2023] [Indexed: 06/19/2023] Open
Abstract
PURPOSE The study evaluates the rate of postoperative formation of a pupillary membrane (PM) and posterior visual axis opacification (PVAO) in infants with and without primary IOL implantation during the first 4 months of infancy. METHODS Medical records for 144 eyes (101 infants) operated between 2005 and 2014 were evaluated. A posterior capsulectomy and anterior vitrectomy were performed. Primary IOL implantation was performed in 68 eyes, while 76 eyes were left aphakic. There were 16 bilateral cases in the pseudophakic group and 27 in the aphakic group. The follow-up period was 54.3 ± 21.05 months and 49.1 ± 18.60 months, respectively. Fisher's exact test was used for statistical analysis. The two-sample t-test with equal variance was used to compare surgery age, follow-up period and time intervals of complications. RESULTS The mean age of surgery was 2.1 ± 0.85 months in the pseudophakic and 2.2 ± 1.01 months in the aphakic group. PM was diagnosed in 40% pseudophakic and 7% aphakic eyes. A second surgery for PVAO was performed in 72% pseudophakic and 16% aphakic eyes. Both were significantly higher in the pseudophakic group. In the pseudophakic group, the number of PVAO was significantly higher in infants operated before 8 weeks of age compared to surgery age 9-16 weeks. The frequency of PM was not age-dependent. CONCLUSION Although it remains feasible to implant an IOL during the primary surgery, even in very young infants, there should always be solid arguments for this decision since it puts the child at higher risk of repeated surgeries under general anaesthesia.

Abstract
PURPOSE To describe the characteristics and prevalence of strabismus and nystagmus in children diagnosed with cataracts using a national insurance claims database. DESIGN Population-based retrospective cohort study. METHODS Patients aged <13 years diagnosed with cataracts (traumatic cataracts excluded) and enrolled continuously in their health care program for ≥5 years after their first cataract diagnosis were identified in a retrospective review of 66 million charts in Optum's de-identified Clinformatics Data Mart Database between 2003 and 2015. Patients were categorized based on age of their first diagnosed cataract, and if cataract surgery was performed. Clinical and demographic factors associated with the occurrence of strabismus and nystagmus were evaluated. RESULTS Of 1636 children diagnosed with cataract, 434 (26.5%) and 109 (6.7%) were diagnosed with strabismus and nystagmus, respectively. Both strabismus and nystagmus were more common in those who underwent cataract surgery (P < .001) and in patients diagnosed with cataract at ≤12 months of age (P < .001). Survival analysis demonstrated that strabismus and nystagmus may be diagnosed 8 years after the initial cataract diagnosis. Cox proportional hazard regression analyses revealed strabismus was associated with cataract surgery, nystagmus, and the diagnosis with cataract at ≤12 months and cataract surgery at >12 months. CONCLUSIONS As strabismus and nystagmus occur more frequently in children diagnosed with cataracts necessitating cataract surgery, regular long-term follow-up is crucial for these children to monitor for the development of strabismus and nystagmus.

Abstract
PURPOSE To study the frequency and types of strabismus in congenital aniridia, the presence of associated nystagmus, foveal hypoplasia, and congenital cataracts. DESIGN Prospective, single-center cohort study. METHODS A review was conducted of 379 medical records of congenital aniridia patients who had a follow-up at the Necker-Enfants malades University Hospital between 2006 and 2022; the target age was between 12 months and 30 years. Ophthalmologic and orthoptic assessments according to age were performed. Strabismus was further analyzed according to the type of aniridia, foveal hypoplasia, and laterality of congenital cataract. RESULTS Strabismus was diagnosed in 150 patients; 73 were included in the study (28 males [38%] and 45 females [62%]), with a mean age of 11.02 years. The mean follow-up was 24 months. Thirty-six (49.3%) presented with familial aniridia, and 37 (50.7%) presented with sporadic aniridia. Thirty-six (49.3%) were diagnosed with esotropia, 37 (50.7%) had exotropia. Nystagmus was detected in 70 patients (96%). Thirty-nine (53.4%) suffered from congenital cataract, 10 unilateral (25.7%) and 29 bilateral (74.3%). Foveal hypoplasia was found in 73 cases (100%); esotropia was predominant in all grades. PAX6 mutation was found in 56 patients (77%). CONCLUSION Strabismus is one of the clinical signs of congenital aniridia. The laterality of congenital cataracts seems to affect the type of strabismus. The grade of foveal hypoplasia has little impact on strabismus but is prevalent for nystagmus. Foveal hypoplasia affects optical focus, which is essential for binocularity; this could explain the poor binocular adjustment leading to strabismus without exotropia or esotropia predominance.

Abstract
Purpose To determine the cumulative incidence of strabismus surgery after pediatric cataract surgery and identify the associated risk factors. Design US population-based insurance claims retrospective cohort study. Participants Patients ≤ 18 years old who underwent cataract surgery in 2 large databases: Optum Clinformatics Data Mart (2003-2021) and IBM MarketScan (2007-2016). Methods Individuals with at least 6 months of prior enrollment were included, and those with a history of strabismus surgery were excluded. The primary outcome was strabismus surgery within 5 years of cataract surgery. The risk factors investigated included age, sex, persistent fetal vasculature (PFV), intraocular lens (IOL) placement, nystagmus and strabismus diagnoses before cataract surgery, and cataract surgery laterality. Main Outcome Measures Kaplan-Meier estimated cumulative incidence of strabismus surgery 5 years after cataract surgery and hazard ratios (HRs) with 95% confidence intervals (CIs) from multivariable Cox proportional hazards regression models. Results Strabismus surgery was performed on 271/5822 children included in this study. The cumulative incidence of strabismus surgery within 5 years after cataract surgery was 9.6% (95% CI, 8.3%-10.9%). Children who underwent strabismus surgery were more likely to be of younger age at the time of cataract surgery, of female sex, have a history of PFV or nystagmus, have a pre-existing strabismus diagnosis, and less likely to have an IOL placed (all P < 0.001). Factors associated with strabismus surgery in the multivariable analysis included age 1 to 4 years (HR, 0.50; 95% CI, 0.36-0.69; P < 0.001) and age > 5 years (HR, 0.13; 95% CI, 0.09-0.18; P < 0.001) compared with age < 1 year at time of cataract surgery, male sex (HR, 0.75; 95% CI, 0.59-0.95; P < 0.001), IOL placement (HR, 0.71; 95% CI, 0.54-0.94; P = 0.016), and strabismus diagnosis before cataract surgery (HR, 4.13; 95% CI, 3.17-5.38; P < 0.001). Among patients with strabismus diagnosis before cataract surgery, younger age at cataract surgery was the only factor associated with increased risk of strabismus surgery. Conclusions Approximately 10% of patients will undergo strabismus surgery within 5 years after pediatric cataract surgery. Children of younger age, female sex, and with a pre-existing strabismus diagnosis undergoing cataract surgery without IOL placement are at greater risk.

Abstract
Objective To evaluate visual outcomes and complications of infantile cataract surgery through a 1-year follow-up period in a real world scenario. Methods and analysis Prospective observational study evaluating infants with cataract undergoing surgery. Results We analysed 173 eyes of 97 infants (76 bilateral); median age 18.7 weeks, (IQR: 11–33.9 weeks). Toxoplasmosis, rubella, cytomegalovirus and herpes infection was the most common aetiology in both unilateral 10 (47.6%) and bilateral 43 (55.1%) cases, followed by familial and syndromic cases. Fifty-four eyes (29.5%) received primary intraocular lens (IOL) implantation. Seventy-five infants (76%) were less than 6 months of age. At 1-year follow-up, mean log MAR best-corrected visual acuity was 1.00±0.08 and 1.21±0.03 in unilateral and bilateral cases respectively (p=0.012), which was not statistically significant. At 1-year follow-up, pseudophakic(1.09±0.05) eyes had a better mean log MAR visual acuity comparing aphakes(1.24±0.04) clinically but was not statistically significant after the application of Bonferroni correction (p=0.012). The mean myopic shift of −2.9 D±0.39 and −4.53 D±0.55 over 1 year was noted in aphakes and pseudophakes, respectively (p=0.016). Visual axis opacification and glaucoma were the most common complications noted in pseudophakes and aphakes, respectively. Conclusion Primary IOL implantation in selected cases of infantile cataract is a feasible option, particularly in cases when optimal aftercare and refractive rehabilitation of aphakia are not possible.

Abstract
AIM To investigate the outcome of contact lens (CL) fitting in aphakic children following lensectomy for congenital cataract. METHOD Retrospective data of 205 aphakic children who visited for CL fitting following lensectomy from 2008 to 2018 were collected. Data includes the demographic details, CL parameters in first and last visit, hours of CL wear, reason for discontinuation of CL, surgical procedures underwent and years of follow up. RESULTS 205 (148 unilateral and 57 bilateral) aphakic children comprised of age group, < 1 month (n = 48), 1-3 months (n = 37), 3-6 months (n = 68), 6-12 months (n = 10), >12 months (n = 42). 173/205(84.39%) children were fitted with rigid gas permeable (RGP) and 32/205(15.6%) were fitted with soft CL at their first visit. 10 children had shifted to soft CL in their follow-up visits due to intolerance to RGP. 97/205(47.32%) children continued CL (55RGP, 42SCL) till the last follow-up for 2.17 ± 2.36 years and wore lens for 3.7 ± 3.65 h per day. Number of lenses replaced was 2 lenses (median) and maximum of 9 lenses over a period of 1-8 visits. The maximum visual acuity achieved was up to 0.2 log Mar units at the youngest age of 4 years on successful CL wear. 60/205(29.26%) children discontinued lenses at different follow-up visits due to IOL implantation(n = 28),using spectacles due to handling difficulty, child uncooperative to lens wear and lens fitting issues(n = 32). 48/205(23.41%) were lost to follow-up after the first visit. The average K (7.46 ± 0.43 mm) showed significant correlation to lens base curve in first visit (7.48 ± 0.41 mm) whereas flat K (7.71 ± 0.38 mm) showed significant correlation in the last visit (7.46 ± 0.39 mm) (p < 0.005). This was well described by a significant diameter change of 8.68 ± 0.31 mm to 9.42 ± 1.77 mm (p < 0.005) at the first and last visit respectively. The refractive error showed a significant difference between first (27.96 ± 5.33D) and last visit (21.97 ± 6.85D) (p < 0.005). CONCLUSION This study witnessed successful contact lens wear in only half of the children. The visual rehabilitation following lensectomy depends on right CL choice and close follow-up.

Abstract
PURPOSE To investigate long-term complications following pediatric cataract surgery with implantation of a heparin-coated PMMA IOL and posterior continuous curvilinear capsulorhexis (PCCC) with anterior vitrectomy versus PCCC without anterior vitrectomy with optic capture buttonholing. SETTING Department of Ophthalmology, Goethe University, Frankfurt, Germany. DESIGN Prospective randomized clinical trial. METHODS Eyes with unilateral or bilateral congenital cataract without further pathologies or former surgeries were randomly assigned in two groups: cataract removal, IOL implantation and PCCC with anterior vitrectomy (AV; group A) or posterior optic buttonholing without anterior vitrectomy (optic capture, OC; group B). The main outcome measures were posterior capsule opacification (PCO), complication rates and refractive development. RESULTS 58 eyes of 41 pediatric cataract surgery patients were included. The mean age at time of operation was 66.05 months (± 29.39). In group A (n=26), two eyes required treatment for posterior capsule opacification, whereas the optic axis remained clear in all eyes in group B (n=30), which was not statistically significant. Additionally, group B had a slightly lower rate of complications. Mean SE after a mean postoperative follow-up of 6.5 years was -0.11 ± 2.51 D (-5.0 to +4.0 D) in group A and -0.08 ± 2.14 D (-5.0 to +4.0 D) in group B, which was not statistically significant either. CONCLUSION Optic capture with a heparin-coated PMMA IOL proved to be a safe technique in the prevention of secondary cataract formation without a higher rate of complications and the necessity of vitrectomy.

Outcomes of the infantile cataract surgery: case series with a 5-year follow-up. Int Ophthalmol 2021; 42:541-547. [PMID: 34633609 DOI: 10.1007/s10792-021-02025-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2020] [Accepted: 09/22/2021] [Indexed: 10/20/2022]
Abstract
PURPOSE To present the 5-year outcomes obtained from the infantile cataract surgery in pediatric population. METHODS Medical records of all patients with unilateral or bilateral infantile cataract who had undergone lensectomy and anterior vitrectomy with or without intraocular lens implantation before 10 years of age were evaluated. Patients with any history of ocular trauma, retinal or corneal dystrophy, ocular or orbital surgery, retinopathy of prematurity, raised intraocular pressure at the time of diagnosis, or incomplete follow-up sessions were excluded from the research. RESULTS A total of 85 eyes belonged to 52 patients were analyzed. Bilateral and unilateral diseases were present in 33 (63.5%) and 19 (36.5%) patients, respectively. After performing the first operation, 43 (50.6%) eyes still remained aphakic. The mean corrected distance visual acuity (CDVA) of the aphakic and pseudophakic eyes was estimated as 0.77 ± 0.52 and 0.43 ± 0.39 logMAR with no statistical difference. The age at the time of performing the cataract surgery was not associated with the final CDVA in either group. Complications in the anterior segment structures were noted in 39 (45%) eyes. Strabismus and amblyopia were noted in 52 (61%) and 75 (88.2%) eyes, respectively. Glaucoma was found in 17 (20%) eyes with no correlation with the final CDVA, age at the time of cataract surgery, or the status of the lens. CONCLUSION Due to high prevalence rates of amblyopia, strabismus, and glaucoma after the infantile cataract surgery, specific attention should be paid to these complications in each follow-up examination.

Abstract
PURPOSES The present meta-analysis compared the postoperative visual performance of primary intraocular lens (IOL) implantation and primary aphakia in cataract infants. METHODS PubMed, Embase, Science Direct and Cochrane Library were searched, and postoperative visual acuity (VA) and complications were extracted and pooled. RESULTS Three randomised controlled trails (RCTs) and five retrospective studies were included. The postoperative VA of children younger than 4.5 years in primary IOL group was better than that in primary aphakia group [MD = -0.14, 95% CI: (-0.23, -0.06), P = .90]. The subgroup analysis based on RCTs and on unilateral cataract surgery revealed the same result. There was no significant difference in the incidence of glaucoma, strabismus, retinal detachment and nystagmus between primary IOL group and primary aphakia group [OR = 1.02, 95% CI: (0.62, 1.68), P = .48 for glaucoma; OR = 0.76, 95% CI: (0.30, 1.90), P = .05 for strabismus; OR = 0.49, 95% CI: (0.07, 3.30), P = .34 for retinal detachment; OR = 1.26, 95% CI: (0.68, 2.36), P = .92 for nystagmus]. The proportion of patients requiring postoperative visual axis opacification (VAO) clearing was higher in primary IOL group than that in primary aphakia group [OR = 9.22, 95% CI: (4.74, 17.96), P = .16]. CONCLUSION For infants under 2 years of age, primary IOL implantation would provide more visual benefits compared with primary aphakia did, though the benefits would taper off with the age reaching 4.5 years. Moreover, the current study revealed a higher VAO incidence r in primary IOL implantation group.

Abstract
As an indispensable part of congenital cataract surgery, intraocular lens (IOL) implantation in infantile patients has long-term positive impacts on visual rehabilitation, as well as postoperative complications inevitably. Timing of IOL implantation in infantile congenital cataract patients is not simply a point-in-time but a personalized decision that comprehensively takes age at surgery, risks of postoperative complications, and economic condition of family in consideration, and combines with choosing suitable IOL type and power. For infants with well-developed eyeballs and good systemic conditions, IOL implantation at six months of age or older is safe and effective. Otherwise, secondary IOL implantation may be a safer choice.

Abstract
PURPOSE To assess the impact on visual development of multifocal versus monofocal intraocular lenses (IOLs) implantation in children following congenital cataract surgery. DESIGN Retrospective interventional consecutive case series. METHODS We reviewed the records of 56 eyes of 43 pediatric patients who underwent congenital cataract surgery with phacoaspiration and simultaneous implantation of IOL under one year of age. Corrected distance visual acuity (CDVA), refractive error and ocular motility disorders were evaluated after a follow-up greater than 4 years. RESULTS We implanted 32 multifocal (18unilateral, Group A and 14bilateral, Group B) and 24monofocal IOLs (12unilateral, Group C and 12bilateral, Group D). Mean follow-up was 6.67 years. Mean CDVA of the eyes with multifocal IOL was 0.75±0.46 logMAR in unilateral cataract surgery and 0.34±0.25logMAR in bilateral ones; with monofocal IOLs was 0.71±0.52logMAR in unilateral and 0.53±0.43logMAR in bilateral ones. No statistically significant difference in CDVA between Groups A and B and Groups C and D has been recorded. Final mean spherical equivalent was -3.88±4.73D; in Group A it was -2.74±4.22D, in Group C was -1.08±1.45D, in Group B was -4.82±4.64D and in Group D was -6.81 ± 4.61D.The difference was statistically significant between Group B and D (p=0.01), but not between Group A and C (p=0.14).Twenty-six patients (60.4%) showed post-operative strabismus. Its surgical correction occurred more in patients with multifocal IOL implanted (p=0.038). CONCLUSIONS Our findings suggest that the use of multifocal IOLs did not show significant advantages in visual development in children following congenital cataract extraction under one year of age if compared with monofocal IOLs.

Abstract
Recent studies indicate the prevalence of myopic refraction in children with pseudophakia, which significantly reduces the functional results of treatment and may be an indication for replacing the intraocular lens (IOL). Therefore, studies conducted to achieve the target refraction in children with pseudophakia are relevant. PURPOSE To determine the risk factors for the prognosis of myopic refraction in children after extraction of congenital cataract and IOL implantation. MATERIAL AND METHODS The study presents the results of refraction examination in 69 (110 eyes) children aged 1 to 12 years 36 months after extraction of congenital cataract with implantation of soft IOL. RESULTS The obtained data of anamnesis, results of ophthalmological, echobiometric, clinical and laboratory studies were subjected to statistical processing assessing the significance of differences in outcomes depending on the impact of possible risk factors for the development of pseudophakic myopia; a regression logistic model and a ROC-curve were constructed. CONCLUSION According to the authors, reliable risk factors for the development of pseudophakic myopia in children can be such indicators as axial eye length at the time of IOL implantation exceeding the age norm by more than 0.2 mm; the child from the first pregnancy; the AL/CR ratio of ≥3.0; myopia on the paired eye; strabismus of more than 4 prism diopters; hereditary load; tension of eye's fibrous capsule: pressure of ≤180 mm Hg at the time of IOL implantation. The presented reliable factors, as well as a combination of less significant signs (the child being outside for less than 1 hour per day, intermarriage of the patient's parents, near-sight visual loads of more than 3 hours per day, the blood Ca level of less than 1.8 mmol/L) can be used for prognosis of the development of pseudophakic myopia and to help make adjustments in the management tactics for patients to achieve target refraction.

Abstract
To analyze the visual acuity and complications between primary intraocular lens (IOL) implantation and contact lens wearing, this literature search was performed with data on patients with congenital cataract younger than 2 years published in March 2019. Seven identified studies enrolling 675 eyes were selected for analysis. Patients with primary IOL implantation owned better visual acuity than those with aphakia who wore the contact lens (weighted mean difference = 0.161; 95% CI, 0.108-0.214). For visual axis opacification (VAO), primary IOL implantation increases the incidence of VAO compared with contact lens wearing (relative risk = 0.23; 95% CI, 0.13-0.42). No statistically significant difference was found between the 2 groups about the prevalence of glaucoma and strabismus. Primary IOL implantation achieved better visual outcomes after cataract extraction in patients younger than 2 years. In addition, no higher risk for complications among primary IOL implantation compared with contact lens wearing was noted. Therefore, implanting a primary IOL during congenital cataract surgery is a better therapy for children younger than 2 years than wearing a contact lens.

Abstract
The article describes the factors affecting the target refraction of pseudophakic eyes of children after extraction of congenital cataracts. The factors include features of the echobiometric parameters of the eye, refraction, comorbidity of congenital cataracts and ocular pathologies, margins of error in calculating strength of the intraocular lens, localization and structure of the artificial lens, as well as correction of obscure or refractive amblyopia in pseudophakic eyes. Development of the algorithm for correction of residual refraction of pseudophakic eyes in children both before and after IOL implantation with consideration of each of those factors currently remains a relevant problem.

Abstract
PURPOSE To compare complications in children up to 4 years old having cataract surgery with intraocular lens (IOL) implantation using 2 techniques: in-the-bag IOL with anterior vitrectomy or optic capture of IOL with no anterior vitrectomy. SETTING Iladevi Cataract & IOL Research Centre, Ahmedabad, India. DESIGN Prospective randomized control clinical trial. METHODS The study included children having cataract surgery with IOL implantation. Patients were randomized to Group 1 (in-the-bag 3-piece hydrophobic acrylic IOL [Acrysof MA60AC] with anterior vitrectomy) or Group 2 (optic capture of the same IOL without anterior vitrectomy). Intraoperative complications were documented. Postoperative visual axis obscuration (VAO), glaucoma, cell deposits on the IOL, and posterior synechiae were compared at 1, 3, 6, and 12 months. RESULTS The study comprised 61 children (61 eyes). The mean ages were 14.8 months ±11.47 (SD) in Group 1 (n = 30) and 18.2 ± 11.47 months in Group 2 (n = 31). Overall, only 1 eye in Group 1 developed a VAO requiring membranectomy 4 months postoperatively, and 2 eyes in Group 1 developed glaucoma over 12 months (P = .49). Intraocular lens cell deposits and posterior synechiae were comparable between groups. The IOL could not be captured in 5 eyes (16.1%); no complications occurred in these eyes. CONCLUSIONS Optic capture of 3-piece hydrophobic acrylic IOLs could be achieved in most eyes. The VAO, glaucoma, and inflammation were comparable 12 months postoperatively. Thus, optic capture of an IOL is an alternative surgical technique that can be used to avoid vitrectomy, even in children younger than 4 years.

Abstract
IMPORTANCE To determine visual and surgical results in children with Marfan syndrome. BACKGROUND Marfan syndrome involves ocular complications which can lead to visual disturbance and amblyopia. Data about the visual and surgical results in children with Marfan syndrome is vital for the clinical management of these patients. DESIGN Retrospective data analysis. PARTICIPANTS Eighty-two eyes of 41 patients with a genetically proved diagnosis of Marfan syndrome. METHODS Medical records of patients with Marfan syndrome were reviewed between 2007 and 2017. Ocular complications, visual acuity (VA) of patients with/without lensectomy and surgical method were evaluated. MAIN OUTCOME MEASURES VA outcomes of patients with Marfan syndrome with/without surgical repair of ectopia lentis. RESULTS In 27 (66%) of the 41 patients a bilateral subluxation of the lens was visible and 14 (52%) patients received lensectomy. The mean age at initial presentation was 12.3 ± 9 years and mean follow-up was 3 years (range 1-7). VA varied from 1.2 to -0.1 logMAR at first examination. At initial presentation, mean VA was 0.1 ± 0.7 logMAR in patients with a normal lens status (n = 14) and 0.3 ± 0.5 logMAR in patients with subluxation of the lens (n = 27) (P < .01). VA improved from 0.2 ± 0.5 logMAR to 0.1 ± 0.5 logMAR (P = .06) in children with subluxation of the lens who did not need a lensectomy (n = 12) and from 0.5 ± 0.5 logMAR to 0.2 ± 0.5 logMAR (P = .02) in patients who were referred to lensectomy with/without secondary lens implantation. CONCLUSIONS AND RELEVANCE In Marfan syndrome subluxation of the lens was found in the majority of children. Improvement of VA resulted in children with subluxation of the lens and following lensectomy.

Abstract
PURPOSE To evaluate the long-term outcome of neodymium:yttrium-aluminum-garnet (Nd:YAG) laser posterior capsulotomy after cataract surgery in children. DESIGN Retrospective case series. METHODS Electronic medical records of pediatric patients who underwent Nd:YAG laser posterior capsulotomy between January 1, 2008, and October 31, 2012, and followed up for more than 5 years were reviewed. RESULTS Thirty-one eyes of 25 patients were included. Only compliant patients assessed during slit-lamp examination and anterior segment photography underwent laser treatment. The mean age at the time of initial laser treatment was 9.04 ± 3.51 years (minimum 56 months), and the mean interval between cataract surgery and initial laser treatment was 28.1 ± 22.1 months. Posterior capsular openings were successfully made in 26 (83.9%) eyes with a single attempt and in 3 (9.7%) eyes with a second attempt. Overall success rate was 93.5%. The logMAR best-corrected visual acuity was significantly improved from 0.61 ± 0.36 to 0.19 ± 0.25 at 1 month posttreatment (P < .0001) and well maintained, at least for 5 years of follow-up, without serious complications. The recurrence of posterior capsular opacity was observed in 7 (24.1%) eyes, which was successfully managed by repeated laser procedure or surgical capsulectomy. CONCLUSIONS By selecting compliant patients and repeated attempts, Nd:YAG laser posterior capsulotomy can be successfully performed in a pediatric population without serious complications. Laser treatment is also a good option for managing recurred posterior capsular opacity. Restored visual acuity can be maintained for at least 5 years.

METHODS Infants who had phacoaspiration, primary posterior capsulotomy, anterior vitrectomy, and primary IOL implantation were evaluated for complications and the need for additional surgery over a 3-year period. The main outcome measures were the rate of complications, adverse events, and need for additional surgery. RESULTS Sixty infants (100 eyes) with a mean age of 7.13 months ± 2.32 (SD) (range 3 to 12 months) were studied. The mean follow-up was 41.2 ± 3.5 months. Indication of additional surgery included visual axis opacification in 13 eyes, pupillary membrane/IOL decentration in 4 eyes, and iris prolapse in 4 eyes. Adverse events included pigment on the IOL in 14 eyes and iridolenticular adhesions in 9 eyes. Ocular hypertension was observed in 2 eyes. The IOL was placed in sulcus or by optic capture in 14 eyes. There was no difference in additional surgery and adverse events between infants aged 6 months or younger versus those older than 6 months (P = .734). CONCLUSION There was a low incidence of adverse events and additional surgery requirement in infants who had cataract surgery with primary IOL implantation.

Ir J Med Sci 2018; 188:1021-1024. [PMID: 30269187 DOI: 10.1007/s11845-018-1908-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2018] [Accepted: 09/21/2018] [Indexed: 10/28/2022]
Abstract
BACKGROUND The Infant Aphakia Treatment Study (IATS) compared the treatment of unilateral cataract in infants aged 1-6 months with primary intraocular lens (IOL) implantation vs aphakia with contact lens (CL) correction. AIMS This study aims to assess the current trends in the treatment of unilateral congenital cataract in infants less than 6 months at surgery in the UK and Ireland. METHODS An anonymous survey was emailed to the 200 members of the BIPOSA mailing list with 14 questions to assess treatment choice (primary intraocular lens (IOL) vs aphakia with contact lens (CL)), reasons for this choice, and assessment of local CL services. RESULTS There were 56 respondents, 39 of whom completed the entire survey. Aphakia with CL was the treatment choice for 74.4% of respondents. A quarter (25.6%) of respondents said they were performing primary IOL implantation prior to the publication of the Infant Aphakia Treatment Study (IATS), but now choose aphakia with CL. Amongst the 20.5% (n = 8) of respondents who chose primary IOL implantation, 5 attributed their choice to "inadequate CL service". The majority (84.6%) of respondents rated their infant CL service as either "good" or "very good". CONCLUSION Aphakia with CL rehabilitation was the most common approach to the treatment of unilateral congenital cataract in infants less than 6 months in this study. The results of the IATS appear to have influenced a change in practice from primary IOL implantation to aphakia and CL visual rehabilitation in approximately one quarter of those surveyed.

Abstract
Purpose To report the long-term outcome of early secondary intraocular lens (IOL) implantation following congenital cataract extraction in a large number of eyes. Methods Data of aphakic children under 30 months of age who underwent secondary IOL implantation and had at least one year of follow-up after the surgery was reviewed. In all of the patients, a foldable three-piece acrylic IOL was implanted in the ciliary sulcus by the same surgeon using the same technique. The database studied included refractive and visual acuity (VA) outcomes and complications. Results Fifty patients (75 eyes) were included. The average age at the time of cataract extraction was 94.20 ± 44.94 days and 20.7 ± 6.0 months in the secondary IOL implantation. After 82.32 ± 48.91 months, the VA was 0.58 ± 0.35 LogMAR and the spherical equivalent was −2.20 ± 4.19 D. There was a negative correlation between a longer follow-up period and myopia at the SE measured (P = .001). The most frequent complications included glaucoma and corectopia. Performing the secondary IOL implantation ≤ 20 months of age was not a risk factor for glaucoma development (P = 0.095). Conclusion Secondary IOL implantation under 30 months of age is an option for children with unsatisfactory management of the optic treatment. A predictable IOL power calculation and satisfactory visual outcomes compared to results of later secondary IOL implantation are possible.

Abstract
Purpose: To study the long-term safety profile and visual outcomes of primary intraocular lens (IOL) implantation in infants <6 months of age. Methods: This was a retrospective observational study conducted at a tertiary eye care center in South India. Infants under 6 months meeting the selection criteria who underwent cataract surgery (lens aspiration, primary posterior capsulorhexis, and anterior vitrectomy) with primary IOL implantation between January 2008 and December 2011 and minimum 3-year follow-up were included. Patient demographics, serial refractions, visual acuity, complications, and associated amblyopia/strabismus were reviewed. Visual acuity, myopic shift, and complications were the outcome measures. Results: Sixty-nine eyes of 38 infants (31 bilateral; mean age: 4.6 months) were reviewed. Mean follow-up was 51 months (range: 36–84). Median logMAR best-corrected visual acuity at the final visit was 0.74 (interquartile range [IQR]: 0.50–0.98) in eyes with bilateral cataracts and 0.87 (IQR: 0.60–1.14) in eyes with unilateral cataracts with an average myopic shift of 6.7 diopters over 4.2 years. Most common postoperative complication was visual axis opacification (VAO) (13 eyes, 18%), necessitating membranectomy followed by pigmentary IOL deposits (11 eyes, 15%), and IOL decentration and glaucoma in four eyes each (5.6%). Mixed linear effect model found no significant association of age, gender, laterality, and postoperative complications with final visual acuity (P ≥ 0.05). Eyes with unilateral cataracts had a greater myopic shift than bilateral cases (P = 0.03). Conclusion: Primary IOL implantation in infants <6 months is reasonably safe in appropriately selected infants. VAO was the most common postoperative complication, and a large myopic shift was observed.

Abstract
Purpose To report the surgical results of unilateral pediatric cataracts from uncertain causes in relatively older children and to identify factors related to better visual outcomes. Methods We retrospectively evaluated the medical records of 39 patients who underwent surgery between the ages of 3 and 10 years for unilateral pediatric cataracts of no known cause. All patients underwent primary intraocular lens implantation and postoperative amblyopia treatment. A postoperative final visual acuity better than 20 / 30 was considered to be a good visual outcome. Results The mean age of patients was 6.0 ± 1.8 years at the time of surgery. The mean preoperative visual acuity was 1.07 ± 0.71 logarithm of the minimum angle of resolution (range, 0.15 to 3.00), while the mean final postoperative visual acuity was 0.47 ± 0.54 logarithm of the minimum angle of resolution (range, 0.00 to 2.00). Of 39 patients, 18 (46.2%) achieved a good visual outcome. Only the preoperative visual acuity maintained a significant association with a good visual outcome according to our multivariate analysis (p = 0.040). A preoperative visual acuity of 20 / 100 or better was found to increase the chance of achieving a good visual outcome by 13.79-fold (95% confidence interval, 1.13 to 167.58). Conclusions The visual outcome of unilateral pediatric cataract surgery for cataracts with no specific cause identified in patients after three years of age could be satisfactory, especially with a preoperative visual acuity of 20 / 100 or better.

Abstract
AIM To evaluate the prevalence, clinical features, and the factors affecting onset of strabismus and nystagmus in patients with bilateral congenital cataracts. METHODS This study evaluated 116 eyes of 58 patients who underwent lens removal for the treatment of bilateral congenital cataracts between January 1999 and January 2011. The presence and type of strabismus and nystagmus were determined before and after surgery. Type of strabismus and final visual acuity were compared in patients with and without nystagmus. Patients were divided into three groups (orthotropia/orthotropia, orthotropia/strabismus, and strabismus/strabismus) according to their preoperative and postoperative ocular alignment. Age at cataract surgery and associations of nystagmus and primary intraocular lens (IOL) implantation with strabismus were analyzed. RESULTS Six patients (10.3%) had strabismus preoperatively and an additional 11 (19.0%) developed postoperative strabismus. Exotropia was more common than esotropia both preoperatively and postoperatively. Eighteen patients (31.0%) had postoperative nystagmus, with sensory nystagmus being the most common type. Of the 18 patients with nystagmus, 10 had strabismus, with exotropia being more common than esotropia. Postoperative visual acuity was poor in patients with nystagmus. Age at cataract surgery and rate of primary IOL implantation were significantly lower, and postoperative nystagmus was more common, in the orthotropia/strabismus group than in the other two groups. CONCLUSION Exotropia and sensory nystagmus are common in patients with bilateral congenital cataracts. Age at cataract surgery and rate of IOL implantation are lower and nystagmus more common in patients with postoperative onset of strabismus. Nystagmus is associated with poor visual prognosis.

Abstract
The development of visual function takes place over many months or years in primate infants. Visual sensitivity is very poor near birth and improves over different times courses for different visual functions. The neural mechanisms that underlie these processes are not well understood despite many decades of research. The puzzle arises because research into the factors that limit visual function in infants has found surprisingly mature neural organization and adult-like receptive field properties in very young infants. The high degree of visual plasticity that has been documented during the sensitive period in young children and animals leaves the brain vulnerable to abnormal visual experience. Abnormal visual experience during the sensitive period can lead to amblyopia, a developmental disorder of vision affecting ∼3% of children. This review provides a historical perspective on research into visual development and the disorder amblyopia. The mismatch between the status of the primary visual cortex and visual behavior, both during visual development and in amblyopia, is discussed, and several potential resolutions are considered. It seems likely that extrastriate visual areas further along the visual pathways may set important limits on visual function and show greater vulnerability to abnormal visual experience. Analyses based on multiunit, population activity may provide useful representations of the information being fed forward from primary visual cortex to extrastriate processing areas and to the motor output.

Abstract
Purpose To evaluate the visual outcomes of dense pediatric cataract surgery in eastern China. Methods Medical records of children who underwent surgery for dense unilateral or bilateral pediatric cataract in Shandong Provincial Hospital between January 2007 and December 2012 were collected. Patients who cooperated with optical correction and aggressive patching of the sound eye and who had a minimum postoperative follow-up of more than 2 years were included. Risk factors for poor visual outcomes were analyzed. Results Of the 105 eligible patients (181 eyes), 76 had bilateral cataract, and 29 unilateral. With a mean follow up of 46.77 mo (range 24.0~96.0 mo), the final best corrected visual acuity (BCVA) of 158 eyes were recorded, and 4.43% (7/158) achieved 0.1 logarithm of the minimum angle of resolution (logMAR) or better; 15.19% (24/158) obtained a BCVA between 0.1 logMAR and 0.3 logMAR; 18.99%, (30/158) between 0.3 logMAR and 0.5 logMAR; 46.84% (74/158), between 0.5 logMAR and 1 logMAR; 14.55%, worse than 1 logMAR. The mean BCVA of the patients who underwent lensectomy before 3 months of age was significantly better than that of patients who underwent lensectomy between 3 and 12 months (p = 0.001). In the same lensectomy age groups, the final BCVA of the children in the bilateral and unilateral groups did not differ significantly (P>0.05). Lensectomy after 3 months of age, postoperative complications, strabismus and nystagmus were shown to be risk factors for poor visual outcomes. Conclusions Lensectomy before 3 months of age, IOL implantation, proper managing of postoperative complications, early optical correction and aggressive postoperative patching of the sound eye would increase the final BCVA for patients with dense pediatric cataract.

Abstract
INTRODUCTION Pediatric cataracts are a huge problem worldwide, and with improving techniques and technology, the surgical treatment and postoperative visual rehabilitation are improving. Despite intraocular lenses(IOLs) being the standard of care for adult cataract surgery, this issue is still somewhat controversial, particularly in young children and infants due to lack of unequivocal evidence. This review therefore summarises the findings from recent studies on the aspect of IOL implantation in pediatric eyes. Areas covered: An extensive literature search was undertaken for published articles on congenital/developmental pediatric cataracts, and IOL implantation, where literature pertinent to traumatic and subluxated cataracts was not included in the review. Pubmed was used for literature search, and keywords entered were : pediatric, cataract surgery, intraocular lens, persistent fetal vasculature, outcomes, complications, visual performance with intraocular lenses. Expert commentary: Recent literature supports IOL implantation in most cases of congenital / developmental pediatric cataracts, and it seems like the way forward. However, the jury is still out on IOL implantation in infants, particularly in bilateral cataracts. Thus, surgeons must be extremely cautious in planning primary IOL implantation in infant eyes, and if they do perform IOL implantation, rigorous followup is mandatory.

Abstract
PURPOSE To report strabismus surgery frequency and outcomes after monocular infantile cataract surgery with or without IOL implantation. METHODS The Infant Aphakia Treatment Study (IATS) is a randomized, multicenter clinical trial comparing treatment of aphakia with a primary IOL or contact lens in 114 infants with a unilateral congenital cataract. This report is a secondary outcome analysis of ocular motor data from IATS patients who underwent strabismus surgery prior to age 5 years. RESULTS Strabismus surgery was performed in 45 (39%) patients (contact lens group [CL], 37%; IOL group, 42% [P = 0.70]). The indications for strabismus surgery were esotropia (62%), exotropia (33%), and hypertropia (4%). Infants who underwent cataract surgery at a younger age were less likely to undergo strabismus surgery (28-48 days, 12/50 [24%]; 49-210 days, 33/64 [52%]; P = 0.0037). Of the 42 patients who underwent strabismus surgery, 14 (33%) had a postoperative distance alignment within 8Δ of orthotropia at age 5 years. The 5-year visual acuity of children with strabismus was the same whether or not strabismus surgery had been performed (1.10 logMAR with surgery vs 1.00 without [P = 0.71]). CONCLUSIONS In this study cohort, cataract surgery performed in the first 6 weeks of life was associated with a reduced frequency of strabismus surgery. Strabismus surgery outcomes in this population are guarded. Surgical improvement of strabismus does not appear to influence long-term visual acuity.

Abstract
PurposeAlthough pediatric cataract surgery has become standardized and safe, further surgical interventions are not uncommon. The purpose of this study was to analyze the incidence of complications in children who required an intraocular intervention.MethodsA retrospective review of medical records of children (<7 years) with cataract who underwent cataract surgery with or without primary posterior chamber intraocular lens (IOL) placement between January 2006 and December 2014 was carried out. Data were collected regarding visual axis opacification (VAO), glaucoma, IOL decentration, intraocular infections, and other indications that required a second intraocular surgery.ResultsOut of 814 (570 pseudophakic and 244 aphakic) eyes of 620 operated children, 45 eyes of 40 children (5.5%, 45/814) needed a second surgery. The most common indication being VAO (2.9%, 24/814), followed by glaucoma (0.73%, 6/814). Incidence of complications was higher in children <1 year (VAO 6.1%, 19/308 and glaucoma 6%, 6/308). Among all children, repeat interventions and VAO were slightly less frequent in pseudophakics (4.91%, 28/570) vs aphakics (6.91%, 17/244) (P=0.31). As VAO was more common in pseudophakic eyes in infants, glaucoma was equally common in both groups. Best-corrected visual acuity improved from 1.6±0.56 LogMAR preoperatively to 0.80±0.50 LogMAR postoperatively.ConclusionsOur study suggests that overall incidence of second intraocular surgery is low after primary pediatric cataract surgery. VAO remains the most common indication followed by secondary glaucoma. Incidence of complications is higher in children <1 year of age at initial surgery.

Abstract
PurposeTo evaluate the prevalence and risk factors of strabismus in children undergoing surgery for unilateral or bilateral cataract with or without intraocular lens implantation.MethodsMedical records of pediatric patients were evaluated from 2000 to 2011. Children undergoing surgery for unilateral or bilateral cataract with at least 1 year of follow-up were included. Children with ocular trauma, prematurity, or co-existing systemic disorders were excluded. The following data were evaluated: strabismus pre- and post-operation; age at surgery; post-operative aphakia or pseudophakia; and visual acuity.ResultsNinety patients were included, 40% had unilateral and 60% had bilateral cataracts. Follow-up was on average 51 months (range: 12-130 months). Strabismus was found preoperatively in 34.4% children, and in 43.3% children at last follow-up. Strabismus developed in 46.2% of children who were orthotropic preoperatively, whereas 32.3% of children who had strabismus before surgery became orthotropic. Strabismus occurred after unilateral or bilateral cataract surgery in 63.9% and 29.6% children, respectively. At the last follow-up, strabismus was found in 46.7% of aphakic and 58.7% of pseudophakic children (P=0.283). Children who developed strabismus were generally operated at a younger age as compared with those without strabismus (mean of 25.9 vs 52.7 months, P<0.001). Final visual acuity was inversely correlated with prevalence of strabismus.ConclusionStrabismus is a frequent complication after cataract surgery in children. Risk factors include unilateral cases and young age at surgery. No correlation was found between prevalence of strabismus and use of intraocular lens. Strabismus was more common in children with poor final visual acuity.

Abstract
Amblyopia is the condition in which reduced visual function exists despite full optical correction and an absence of observable ocular pathology. Investigation of the underlying neurology of this condition began in earnest around 40 years ago with the pioneering studies conducted by Hubel and Wiesel. Their early work on the impact of monocular deprivation and strabismus initiated what is now a rapidly developing field of cortical plasticity research. Although the monocular deprivation paradigm originated by Hubel and Wiesel remains a key experimental manipulation in studies of cortical plasticity, somewhat ironically, the neurology underlying the human conditions of strabismus and amblyopia that motivated this early work remains elusive. In this review, the authors combine contemporary research on plasticity and development with data from human and animal investigations of amblyopic populations to assess what is known and to reexamine some of the key assumptions about human amblyopia.

Abstract
PURPOSE To evaluate the incidence of strabismus in congenital and developmental cataract surgery in patients with a follow-up longer than five years. METHODS All patients with congenital and developmental cataracts observed from 1996 to 2013 with a follow-up longer than five years were retrospectively included. RESULTS We included 117 patients (58 females and 59 males, mean age 0.62±0.3 years, 160 eyes) with congenital cataracts and 73 patients (32 females and 41 males, mean age 6.63±0.7 years, 121 eyes) with developmental cataracts. Before cataract surgery, strabismus was present in 88 patients with congenital cataracts (75.2%) and in 30 patients with developmental cataracts (41.1%) (p=0.01). After a follow-up of 9.26±1.3 years (range, 5-14 years), a significantly greater incidence of strabismus was observed after surgery only in patients with unilateral congenital cataracts who underwent cataract removal and primary IOL implantation (p=0.02). Distance BCVA and near BCVA were better after surgery for developmental cataracts (p<0.05). Presence of binocular vision was more frequent after surgery for developmental cataracts (p=0.001). CONCLUSION Incidence of strabismus and postsurgical onset of strabismus at long-term follow-up was greater in patients with congenital cataracts.

Abstract
Axial length (AL) is a significant indicator of eyeball development, but reports on the overall status of axial development in congenital cataract (CC) patients and its relationship with patient demographics, such as age, sex, and laterality, are rare. We prospectively investigated the AL of 1,586 patients ≤18 years old and undergoing cataract surgery in China from January 2005 to December 2014. Of these 3,172 eyes, a logarithmic correlation between AL and age in CC patients was calculated, and an age of approximately 2 years was found to be a turning point in the growth rate of AL. A considerable variation was observed in CC patients of the same age. Furthermore, 2–6 years old boys had longer AL than girls. The AL of affected eye in unilateral patients was longer than that of the contralateral eye in 2–6 years age group and longer than that of eye in bilateral CC patients in all age groups. These findings indicate that the development of the length of eyeballs in CC patients is influenced by multiple factors in addition to age. A full understanding of the distribution of AL may provide a useful reference for judging the timing of surgery in CC patients.

Abstract
PURPOSE To evaluate sensorimotor outcomes among children in the Infant Aphakia Treatment Study (IATS). METHODS Secondary outcome analysis was performed in this randomized, multicenter, clinical trial comparing treatment of unilateral aphakia with a primary intraocular lens (IOL) or contact lens (CL) correction. The alignment characteristics and sensory status of children through age 5 years were evaluated. RESULTS In the IATS study, 91 of 112 children (81%) developed strabismus through age 5 years. Of 34 infants who were orthotropic at near 12 months after cataract surgery, at age 5 years 14 (41%) were orthotropic at distance, and 15 (44%) were orthotropic at near at age 5 years without strabismus surgery. Eight of 56 children (14%) in the CL group and 13 of 56 (23%) in the IOL group were orthotropic at distance (P = 0.33) at 5 years of age and had no history of strabismus surgery. Thirteen of 48 (27%) who underwent cataract surgery prior to 49 days of age compared to 8 of 64 (13%) who had surgery after 49 days were orthotropic (P = 0.085). Median visual acuity in the operative eye was 0.4 logMAR (20/50) for children with orthotropia or microtropia (<10(Δ)) versus 1.10 logMAR (20/252) for strabismus ≥10(Δ) (P = 0.0001). Stereopsis was detected in 12 of 21 children (57%) with orthotropia versus 16 of 89 (18%) children with strabismus (P = 0.0006). CONCLUSIONS IOL placement does not reduce the development of strabismus after monocular congenital cataract surgery. Improved ocular alignment by age 5 years correlated strongly with improved visual acuity and stereopsis.

Abstract
IMPORTANCE Glaucoma-related adverse events constitute major sight-threatening complications of cataract removal in infancy, yet their relationship to aphakia vs primary intraocular lens (IOL) implantation remains unsettled. OBJECTIVE To identify and characterize cases of glaucoma and glaucoma-related adverse events (glaucoma + glaucoma suspect) among children in the Infant Aphakia Treatment Study by the age of 5 years. DESIGN, SETTING, AND PARTICIPANTS A multicenter randomized clinical trial of 114 infants with unilateral congenital cataract in referral centers who were between ages 1 and 6 months at surgery. Mean follow-up was 4.8 years. This secondary analysis was conducted from December 23, 2004, to November 13, 2013. INTERVENTIONS Participants were randomized at cataract surgery to either primary IOL or no IOL implantation (contact lens). Standardized definitions of glaucoma and glaucoma suspect were created for the Infant Aphakia Treatment Study and applied for surveillance and diagnosis. MAIN OUTCOMES AND MEASURES Development of glaucoma and glaucoma + glaucoma suspect in operated on eyes for children up to age 5 years, plus intraocular pressure, visual acuity, and axial length at age 5 years. RESULTS Product limit estimates of the risk for glaucoma and glaucoma + glaucoma suspect at 4.8 years after surgery were 17% (95% CI, 11%-25%) and 31% (95% CI, 24%-41%), respectively. The contact lens and IOL groups were not significantly different for either outcome: glaucoma (hazard ratio [HR], 0.8; 95% CI, 0.3-2.0; P = .62) and glaucoma + glaucoma suspect (HR, 1.3; 95% CI, 0.6-2.5; P = .58). Younger (vs older) age at surgery conferred an increased risk for glaucoma (26% vs 9%, respectively) at 4.8 years after surgery (HR, 3.2; 95% CI, 1.2-8.3), and smaller (vs larger) corneal diameter showed an increased risk for glaucoma + glaucoma suspect (HR, 2.5; 95% CI, 1.3-5.0). Age and corneal diameter were significantly positively correlated. Glaucoma was predominantly open angle (19 of 20 cases, 95%), most eyes received medication (19 of 20, 95%), and 8 of 20 eyes (40%) underwent surgery. CONCLUSIONS AND RELEVANCE These results suggest that glaucoma-related adverse events are common and increase between ages 1 and 5 years in infants after unilateral cataract removal at 1 to 6 months of age; primary IOL placement does not mitigate their risk but surgery at a younger age increases the risk. Longer follow-up of these children may further characterize risk factors, long-term outcomes, potential differences between eyes having primary IOL vs aphakia, and optimal timing of unilateral congenital cataract removal.

Abstract
PURPOSE To study visual outcomes and stereopsis after a 3-8 year follow-up in unilateral congenital and developmental cataracts. DESIGN Clinical case series. METHODS Children who underwent surgery for unilateral pediatric cataract from 2004 to 2008 were traced and reexamined prospectively from 2010 to 2011. Demographic and clinical factors were noted from their retrospective chart readings. All children underwent visual acuity assessment and comprehensive ocular examinations including stereoacuity in a standardized manner during the prospective follow-up visits. Details of amblyopia management were recorded for univariate and multivariate analyses. RESULTS Forty-eight eyes of 48 children had a mean follow-up of 4.4 years between surgery and assessment (SD, 1.6 years). Twenty-four (50%) were boys, and the average age at surgery was 10.2 years (SD, 4.1). Two (4.2%) were congenital, 14 (29.2%) developmental, and 32 (66.7%) congenital/developmental cataracts. Preoperatively, 38 (79.2%) had vision less than 3/60. After surgery, 12 (25%) had improved best-corrected visual acuity (BCVA) of 6/18 or greater, 4 (8.3%) had BCVA of 6/24 to 6/60, and 32 (66.7%) had BCVA of less than 6/60. Eleven (22.9%) had binocular single vision 480 seconds or less of arc on Titmus test. Preoperative vision (P = 0.034) was significantly associated with postoperative visual outcomes, but not age at surgery (P = 0.14), sex (P = 0.897), type of surgery (P = 0.371), or type of intraocular lens (P = 0.66). The use of phacoemulsification was associated with better vision, but it was not significant (P = 0.069). CONCLUSIONS Long-term visual outcomes in unilateral pediatric cataracts were subnormal due to deprivation amblyopia, but vision improved over preoperative levels and helped in binocular stereoacuity. Some preoperative vision was associated with better visual outcomes.

Abstract
PURPOSE This study aimed to determine the incidence and characteristics of strabismus following congenital cataract surgery in infants. MATERIALS AND METHODS Patients aged <12 months who underwent surgery for congenital cataract and were followed-up for ≥1 years were included. Patients that had strabismus prior to surgery were excluded. Data regarding gender, cataract laterality, morphology, and density, age at the time of cataract surgery, ocular motility post surgery, and the presence of nystagmus were retrospectively obtained from the patients' records. RESULTS The study included 79 patients (48 male and 31 female). Unilateral surgery was performed in 14 of the patients, versus bilateral surgery in 65. Strabismus did not occur post surgery in 32 (40.5 %) of the patients (group 1), whereas 47 (59.5 %) (group 2) developed strabismus following surgery. The patients in group 1 were followed-up for a mean 50.7 ± 38.5 months, versus 50.3 ± 39 months in group 2. Mean age at the time of cataract surgery in groups 1 and 2 was 3.6 ± 1.9 years and 4.6 ± 3.2 months respectively. Mean duration of time between cataract surgery and the development of strabismus was 13.3 ± 13 months (range: 1-60 months). Unilateral cases were more prone to develop strabismus, which was statistically significant (p = 0.028). Age at the time of cataract surgery, gender, cataract density, the occurrence of aphakic glaucoma, the presence of nystagmus, and additional ocular surgery were not significantly associated with the development of strabismus. CONCLUSION Strabismus develops more frequently in children undergoing cataract surgery. In the present study strabismus occurred in more of the patients that underwent unilateral surgery. Based on the present findings, we think that long-term careful follow-up to monitor the development of strabismus is required in all infants undergoing cataract surgery, especially unilateral cases.

Abstract
PURPOSE To compare primary intra-ocular lens (IOL) implantation with use of press-on spherical lens for aphakia correction following unilateral infantile cataract removal. METHODS Sixty infants with a unilateral cataract underwent cataract surgery and were randomly assigned to the IOL (A group) or no IOL group (B group). Residual refractive error was corrected with spectacles in the A group and a press-on spherical lens was used to treat aphakia in the B group. Grating visual acuity (VA) was measured and patients were followed for up to 1 year. RESULTS LogMAR VA in the operated eyes of both groups was significantly better 1 year than 1 month after surgery. Mean logMAR VA difference between 1 year and 1 month after surgery was higher in the A group (0.457 ± 0.110) than in the B group (0.323 ± 0.114, p < 0.0001). Serious inflammation occurred significantly more often in the A group than in the B group (p = 0.007). Visual axis opacity occurred more often in the A group than in the B group (pupillary membrane: A: six eyes, 20%, B: none, p = 0.024; lens reproliferation: A: 10 eyes, 33%, B: two eyes, 7%, p = 0.021). Glaucoma occurred equally in both groups (p = 0.612). No other complications occurred. CONCLUSIONS Primary IOL implantation appears to be a relatively safe, effective optical correction strategy following unilateral cataract extraction in this age group. Patients for whom an IOL is not suitable can be treated with a press-on spherical lens for optical correction.

Abstract
PURPOSE To compare rates and severity of complications between infants undergoing cataract surgery with and without intraocular lens (IOL) implantation. DESIGN Prospective randomized clinical trial. METHODS A total of 114 infants were enrolled in the Infant Aphakia Treatment Study, a randomized, multi-center (12) clinical trial comparing the treatment of unilateral aphakia in patients under 7 months of age with a primary IOL implant or contact lens. The rate, character, and severity of intraoperative complications, adverse events, and additional intraocular surgeries during the first 5 postoperative years in the 2 groups were examined. RESULTS There were more patients with intraoperative complications (28% vs 11%, P = .031), adverse events (81% vs 56%, P = .008), and more additional intraocular surgeries (72% vs 16%, P < .0001) in the IOL group than in the contact lens group. However, the number of patients with adverse events in the contact lens group increased (15 to 24) in postoperative years 2-5 compared to the first postoperative year, while it decreased (44 to 14) in years 2-5 compared to the first postoperative year in the IOL group. If only one half of the patients in the contact lens (aphakic) group eventually undergo secondary IOL implantation, the number of additional intraocular surgeries in the 2 groups will be approximately equal. CONCLUSION The increased rate of complications, adverse events, and additional intraocular surgeries associated with IOL implantation in infants <7 months of age militates toward leaving babies aphakic if it is considered likely that the family will be successful with contact lens correction.

Abstract
IMPORTANCE The efficacy and safety of primary intraocular lens (IOL) implantation during early infancy is unknown. OBJECTIVE To compare the visual outcomes of patients optically corrected with contact lenses vs IOLs following unilateral cataract surgery during early infancy. DESIGN, SETTING, AND PARTICIPANTS The Infant Aphakia Treatment Study is a randomized clinical trial with 5 years of follow-up that involved 114 infants with unilateral congenital cataracts at 12 sites. A traveling examiner assessed visual acuity at age 4.5 years. INTERVENTIONS Cataract surgery with or without primary IOL implantation. Contact lenses were used to correct aphakia in patients who did not receive IOLs. Treatment was determined through random assignment. MAIN OUTCOMES AND MEASURES HOTV optotype visual acuity at 4.5 years of age. RESULTS The median logMAR visual acuity was not significantly different between the treated eyes in the 2 treatment groups (both, 0.90 [20/159]; P = .54). About 50% of treated eyes in both groups had visual acuity less than or equal to 20/200. Significantly more patients in the IOL group had at least 1 adverse event after cataract surgery (contact lens, 56%; IOL, 81%; P = .02). The most common adverse events in the IOL group were lens reproliferation into the visual axis, pupillary membranes, and corectopia. Glaucoma/glaucoma suspect occurred in 35% of treated eyes in the contact lens group vs 28% of eyes in the IOL group (P = .55). Since the initial cataract surgery, significantly more patients in the IOL group have had at least 1 additional intraocular surgery (contact lens, 21%; IOL, 72%; P < .001). CONCLUSIONS AND RELEVANCE There was no significant difference between the median visual acuity of operated eyes in children who underwent primary IOL implantation and those left aphakic. However, there were significantly more adverse events and additional intraoperative procedures in the IOL group. When operating on an infant younger than 7 months of age with a unilateral cataract, we recommend leaving the eye aphakic and focusing the eye with a contact lens. Primary IOL implantation should be reserved for those infants where, in the opinion of the surgeon, the cost and handling of a contact lens would be so burdensome as to result in significant periods of uncorrected aphakia.

Abstract
OBJECTIVE To evaluate the characteristics of strabismus in infants who underwent cataract surgery with and without intraocular lens (IOL) implantation. DESIGN Secondary outcome analysis in a prospective, randomized clinical trial. PARTICIPANTS The Infant Aphakia Treatment Study is a randomized, multicenter (n = 12), clinical trial comparing treatment of aphakia with a primary IOL or contact lens in 114 infants with a unilateral congenital cataract. INTERVENTION Infants underwent cataract surgery with or without placement of an IOL. MAIN OUTCOME MEASURES The proportion of patients in whom strabismus developed during the first 12 months of follow-up was calculated using the life-table method and was compared across treatment groups and age strata using a log-rank test. RESULTS Strabismus developed within the first 12 months of follow-up in 38 pseudophakic infants (life-table estimate, 66.7%) and 42 infants (life-table estimate, 74.5%) treated with contact lenses (P = 0.59). The younger cohort (<49 days) at the time of surgery demonstrated less strabismus (29 of 50; life-table estimate, 58.0%) than the older cohort (≥ 49 days; 51 of 64; life-table estimate, 80.0%; P<0.01). CONCLUSIONS Intraocular lens placement does not prevent the early development of strabismus after congenital cataract surgery. However, strabismus was less likely to develop in infants whose cataract was removed at an earlier age.
