[PMID: 35102246 PMCID: PMC9905087 DOI: 10.1038/s41433-022-01942-6] [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: 03/07/2021] [Revised: 12/17/2021] [Accepted: 01/17/2022] [Indexed: 11/09/2022] Open
Abstract
BACKGROUND Timely management of aphakic children is critical for the rehabilitation of adequate visual gain. This study aims to evaluate the long-term efficacy of scleral contact lenses in terms of visual outcomes, complications, and compliance in aphakic children. METHODS Retrospective data review of children with congenital or acquired cataract, or subluxated crystalline lenses, who underwent lensectomy from 2004 to 2018 and who used scleral contact lenses for refractive correction. Collected data from the follow up period included recorded aphakic refraction and visual acuity, complications following scleral contact lens wear documented in the clinic and ophthalmic emergency room and compliance to lens wear according to parental feedback on every visit in the clinic. RESULTS 76% of cases, with final best corrected visual acuity (BCVA) of 20/40 or better achieved in seventeen eyes (34%). The rate of amblyopia was 50%. Strabismus developed in 56% of children, and those had less favourable visual outcomes (0.43 ± 0.4 LogMAR without strabismus and 0.8 ± 0.5 LogMAR with strabismus, p = 0.015). No corneal infections were documented during the follow up. Main adverse effect on the ocular surface was superficial punctate keratopathy (n = 16). Compliance was good in 48 children (96%)- except for two cases, the scleral lenses were tolerated well by all children. CONCLUSION Scleral contact lenses are an effective means of visual rehabilitation in aphakic children after lensectomy and may be used long-term with good compliance of wear, excellent visual outcomes, and tolerable adverse events.

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
The medical use of contact lenses is a solution for many complex ocular conditions, including high refractive error, irregular astigmatism, primary and secondary corneal ectasia, disfiguring disease, and ocular surface disease. The development of highly oxygen permeable soft and rigid materials has extended the suitability of contact lenses for such applications. There is consistent evidence that bandage soft contact lenses, particularly silicone hydrogel lenses, improve epithelial healing and reduce pain in persistent epithelial defects, after trauma or surgery, and in corneal dystrophies. Drug delivery applications of contact lens hold promise for improving topical therapy. Modern scleral lens practice has achieved great success for both visual rehabilitation and therapeutic applications, including those requiring retention of a tear reservoir or protection from an adverse environment. This report offers a practical and relevant summary of the current evidence for the medical use of contact lenses for all eye care professionals including optometrists, ophthalmologists, opticians, and orthoptists. Topics covered include indications for use in both acute and chronic conditions, lens selection, patient selection, wear and care regimens, and recommended aftercare schedules. Prevention, presentation, and management of complications of medical use are reviewed.

Abstract
Congenital and childhood cataracts are uncommon but regularly seen in the clinics of most paediatric ophthalmology teams in the UK. They are often associated with profound visual loss and a large proportion have a genetic aetiology, some with significant extra-ocular comorbidities. Optimal diagnosis and treatment typically require close collaboration within multidisciplinary teams. Surgery remains the mainstay of treatment. A variety of surgical techniques, timings of intervention and options for optical correction have been advocated making management seem complex for those seeing affected children infrequently. This paper summarises the proceedings of two recent RCOphth paediatric cataract study days, provides a literature review and describes the current UK 'state of play' in the management of paediatric cataracts.

[PMID: 30894149 PMCID: PMC6425554 DOI: 10.1186/s12886-019-1088-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2018] [Accepted: 03/13/2019] [Indexed: 11/18/2022] Open
Abstract
Background Congenital cataract is currently one of the leading blindness-causing eye diseases in children. Surgical treatment only opens the visual pathway for children. The postoperative recovery of visual function is also dependent on effective optical correction and visual function training. In this study, we analyzed the changes in eye-related parameters, adverse events and the annual cost of rigid gas permeable contact lens (RGPCL) and spectacles correction in infants with monocular aphakia after congenital cataract surgery. Methods To analyze the postoperative visual acuity, strabismus, nystagmus, myopic shift, globe axial length growth, adverse events, patient adherence to patching, and annual cost for patients with unilateral congenital cataract who underwent cataract surgery. Rigid gas permeable contact lenses or spectacles were used to correct aphakia after congenital cataract. Results Of the 49 patients, 20 patients with unilateral aphakia who used RGPCL were in group 1. Group 2 comprised 14 patients with persistent fetal vasculature (PFV) who used RGPCL, and there were 15 patients with spectacles in group 3. In group 1, there were important improvements in visual acuity, strabismus and nystagmus. In groups 2 and 3, there were no significant improvements in visual acuity, strabismus or nystagmus. Patients with a good adherence to patching had better visual acuity after the operation than patients who did not, in groups 1 and 3. There were no significant differences in myopic shift or rate of globe axial length growth among the 3 groups. No patients in group 1 had ocular disease that affected visual acuity. The mean annual expenses of the RGPCL group was 3965 yuan, and the mean annual cost of spectacles was 1140 yuan to 2500 yuan. Conclusion RGPCL is a safe and effective optical correction method for patients with monocular aphakia after congenital cataract surgery. Spectacles are not an ideal optical correction. Using RGPCL to correct patients with PFV, the final visual acuity improved, but the difference was not statistically significant. There were no improvements in strabismus or nystagmus in patients with PFV.

Abstract
PURPOSE To report the prevalence of anisometropia at age 5 years after unilateral intraocular lens (IOL) implantation in infants. DESIGN Prospective randomized clinical trial. METHODS Fifty-seven infants in the Infant Aphakia Treatment Study (IATS) with a unilateral cataract were randomized to IOL implantation with an initial targeted postoperative refractive error of either +8 diopters (D) (infants 28 to <48 days of age) or +6 D (infants 48-210 days of age). Anisometropia was calculated at age 5 years. Six patients were excluded from the analyses. RESULTS Median age at cataract surgery was 2.2 months (interquartile range [IQR], 1.2, 3.5 months). The mean age at the age 5 years follow-up visit was 5.0 ± 0.1 years (range, 4.9-5.4 years). The median refractive error at the age 5 years visit of the treated eyes was -2.25 D (IQR -5.13, +0.88 D) and of the fellow eyes +1.50 D (IQR +0.88, +2.25). Median anisometropia was -3.50 D (IQR -8.25, -0.88 D); range -19.63 to +2.75 D. Patients with glaucoma in the treated eye (n = 9) had greater anisometropia (glaucoma, median -8.25 D; IQR -11.38, -5.25 D vs no glaucoma median -2.75; IQR -6.38, -0.75 D; P = .005). CONCLUSIONS The majority of pseudophakic eyes had significant anisometropia at age 5 years. Anisometropia was greater in patients that developed glaucoma. Variability in eye growth and myopic shift continue to make refractive outcomes challenging for IOL implantation during infancy.

Abstract
PURPOSE To report the myopic shift at 5 years of age after cataract surgery with intraocular lens (IOL) implantation for infants enrolled in the Infant Aphakia Treatment Study (IATS). METHODS Refractions were performed at 1 month and every 3 months postoperatively until age 4 years and then at ages 4.25, 4.5, and 5 years. The change in refraction over time was estimated by linear mixed model analysis. RESULTS Intraocular lens implantation was completed in 56 eyes; 43 were analyzed (median age, 2.4 months; range, 1.0-6.8 months). Exclusions included 11 patients with glaucoma, 1 patient with Stickler syndrome, and 1 patient with an IOL exchange at 8 months postoperatively. The mean rate of change in a myopic direction from 1 month after cataract surgery to age 1.5 years was 0.35 diopters (D)/month (95% confidence interval [CI], 0.29-0.40 D/month); after age 1.5 years, the mean rate of change in a myopic direction was 0.97 D/year (95% CI, 0.66-1.28 D/year). The mean refractive change was 8.97 D (95% CI, 7.25-10.68 D) at age 5 years for children 1 month of age at surgery and 7.22 D (95% CI, 5.54-8.91 D) for children 6 months of age at surgery. The mean refractive error at age 5 years was -2.53 D (95% CI, -4.05 to -1.02). CONCLUSIONS After IOL implantation during infancy, the rate of myopic shift occurs most rapidly during the first 1.5 years of life. Myopic shift varies substantially among patients. If the goal is emmetropia at age 5 years, then the immediate postoperative hypermetropic targets should be +10.5 D at 4 to 6 weeks and +8.50 D from 7 weeks to 6 months. However, even using these targets, it is likely that many children will require additional refractive correction given the high variability of refractive outcomes.

Abstract
Purpose: To evaluate the long-term visual outcomes and complications of the piggyback intraocular lens (IOL) implantation compared to aphakia for infantile cataract. Patients and Methods: In a comparative study from 1998 to 2007, piggyback IOL implantation (piggyback IOL group) was performed for 14 infants (23 eyes) with infantile cataract and 20 infants (32 eyes) who were aphakic (aphakia group) after infantile cataract surgery. Data were collected on logMAR visual acuity, and postoperative complications over a mean follow-up time of 6.2 ± 1.7 years and 5.8 ± 1.7 years. Results: The mean age at surgery was 7.5 ± 0.6 months and 6.0 ± 3.3 months for the piggyback and the aphakic group respectively (P > 0.05). At the last follow-up visit, visual acuity was 0.85 ± 0.73 (median = 0.70, interquartile range = 0.3–1.32) in the piggyback IOL group and 0.89 ± 0.56 (median = 0.86, interquartile range = 0.50–1.24) in the aphakic group (P > 0.05). There was a positive relationship between age and visual outcomes in the aphakic group (r = 0.4, P = 0.04) but not in the piggyback IOL group (P = 0.48). There was no significant difference between the mean myopic shift in the piggyback IOL group (∑5.28 ± 1.06 D) and the aphakic group (∑5.10 ± 1.02 D) (P > 0.05). The incidence of reoperation due to complications in piggyback IOL group was higher than aphakic group (%48 vs. %16, respectively, P ≤ 0.01). However, in patients older than 6 months, this risk was not significantly different compared to the aphakic group. Conclusions: Although piggyback IOL implantation for infantile cataract is optically acceptable as a treatment option, there is no significant difference in visual outcomes compared to aphakia. The incidence in reoperation due to complications in patients aged 6 months or younger is higher than those treated with aphakia.

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
Cataract is a significant cause of visual disability in the pediatric population worldwide and can significantly impact the neurobiological development of a child. Early diagnosis and prompt surgical intervention is critical to prevent irreversible amblyopia. Thorough ocular evaluation, including the onset, duration, and morphology of a cataract, is essential to determine the timing for surgical intervention. Detailed assessment of the general health of the child, preferably in conjunction with a pediatrician, is helpful to rule out any associated systemic condition. Although pediatric cataracts have a diverse etiology, with the majority being idiopathic, genetic counseling and molecular testing should be undertaken with the help of a genetic counselor and/or geneticist in cases of hereditary cataracts. Advancement in surgical techniques and methods of optical rehabilitation has substantially improved the functional and anatomic outcomes of pediatric cataract surgeries in recent years. However, the phenomenon of refractive growth and the process of emmetropization have continued to puzzle pediatric ophthalmologists and highlight the need for future prospective studies. Posterior capsule opacification and secondary glaucoma are still the major postoperative complications necessitating long-term surveillance in children undergoing cataract surgery early in life. Successful management of pediatric cataracts depends on individualized care and experienced teamwork. We reviewed the etiology, preoperative evaluation including biometry, choice of intraocular lens, surgical techniques, and recent developments in the field of childhood cataract.

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
Amblyopia is a neurodevelopmental disorder of vision associated with decreased visual acuity, poor or absent stereopsis, and suppression of information from one eye.(1,2) Amblyopia may be caused by strabismus (strabismic amblyopia), refractive error (anisometropic amblyopia), or deprivation from obstructed vision (deprivation amblyopia). 1 In the developed world, amblyopia is the most common cause of childhood visual impairment, 3 which reduces quality of life 4 and also almost doubles the lifetime risk of legal blindness.(5, 6) Successful treatment of amblyopia greatly depends on early detection and treatment of predisposing disorders such as congenital cataract, which is the most common cause of deprivational amblyopia. Understanding the genetic causes of congenital cataract leads to more effective screening tests, early detection and treatment of infants and children who are at high risk for hereditary congenital cataract.

Abstract
PURPOSE We describe our experience correcting a cohort of infants with contact lenses in the Infant Aphakia Treatment Study. MATERIALS AND METHODS Fifty-seven infants 1-6 months of age were randomized to contact lens wear. An examination under anesthesia was performed at the time of enrollment and at approximately 1 year of age. A traveling examiner assessed visual acuity at approximately 1 year of age. RESULTS Forty-two treated eyes (74 %) were fitted with silicone elastomer (SE) contact lenses; 12 eyes (21 %) with rigid gas permeable (RGP) contact lenses, and 3 eyes (5%) wore both lens types. Median visual acuity was +0.80 logMAR in both lens type-wearing groups. The mean (± SD) keratometric power of the treated eyes was 46.3±2.8 D at baseline and 44.6±2.3 D at 1 year of age for a mean decrease of 0.2±0.2 D/mo. Keratometric astigmatism of treated eyes was 1.98±1.37 D at baseline and 1.62±0.98 D at 1 year of age for a mean decrease of 0.05±0.2 D/mo. The mean RGP lens base curve at baseline was 47.62 D±2.62 D versus 47.00 D±3.50 D at 12 months after surgery. Children wearing SE lenses required a mean of 10.9 replacements (range 2-24) compared to 16.8 replacements (range 8-32) for children wearing RGP lenses. Three adverse events occurred. CONCLUSIONS Contact lenses were worn successfully with relatively few adverse events by a cohort of infants with unilateral aphakia. The visual acuity results were identical independent of the contact lens material or modality. RGP lenses needed replacement more often than SE lenses.

Abstract
BACKGROUND Little information is available on factors that predict adherence to patching in infants. We evaluated data from the Infant Aphakia Treatment Study, a randomized clinical trial of treatment for infants with unilateral congenital cataracts, to investigate factors associated with successful adherence to patching protocols. METHODS In the Infant Aphakia Treatment Study, patching was prescribed 1 hour daily per month of age until 8 months of age and 50% of waking hours thereafter. A centrally located staff member inquired about the patient's adherence to patching in a phone interview with the primary caregiver. Analyses used χ(2) tests of independence and logistic regression to identify predictors of reported adherence and of achieving adherence rates of at least 75% ("good") and 90% ("excellent"). RESULTS A total of 104 caregivers provided data on patching 3 months after surgery, at which time 60% reported patching at least 75% of the prescribed time. Reported adherence was not associated with the type of treatment (P = 0.73) but was better in children with private insurance (P = 0.01) and for children with mothers reporting lower levels of parenting stress (P = 0.03). CONCLUSIONS Most caregivers reported being able to adhere to prescribed patching shortly after extraction of a unilateral congenital cataract. The type of correction (intraocular lens vs contact lens) was not associated with the amount of patching achieved, whereas family socioeconomic status and maternal stress appeared to play a role.

Abstract
BACKGROUND The Infant Aphakia Treatment Study is a randomized trial that compares the treatment of unilateral congenital cataract with primary intraocular lens (IOL) implantation versus aphakic contact lens (CLs). The purpose of this study was to compare the outcomes for infants with lens opacity associated with persistent fetal vasculature (PFV) to those without. METHODS Retrospective subgroup analysis of grating visual acuity at 1 year of age and adverse events up to 1 year after surgery in eyes identified intraoperatively as having evidence of mild PFV from the IATS. RESULTS Of 83 infants, 18 (22%: 11 CL, 7 IOL) had PFV. Median logMAR visual acuity was 0.88 for patients with PFV and 0.80 for patients without PFV (P = 0.46). One or more adverse events up to 1 year after surgery occurred in 12 infants (67%) with PFV and 30 infants (46%) without PFV (P = 0.18). The incidence of adverse events was significantly greater in patients with PFV compared with patients without PFV in the CL group (55% vs 20%, P = 0.049) but not in the IOL group (86% vs 71%, P = 0.65), possibly because all children receiving IOLs had greater rates of adverse events when compared with aphakic children (73% vs 29%, P < 0.001). CONCLUSIONS Aphakic infants with mild PFV treated with CL had a greater incidence of adverse events after lensectomy compared with children with other forms of unilateral congenital cataract; nevertheless, similar visual outcomes at 1 year after surgery were obtained.
