Acta Ophthalmol 2024. [PMID: 38251769 DOI: 10.1111/aos.16630] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 12/20/2023] [Accepted: 01/05/2024] [Indexed: 01/23/2024]
Abstract
PURPOSE To report on the occurrence of postoperative visual axis opacification (VAO) in children younger than 5 years of age operated for cataract in Sweden, and to analyse correlations with age at surgery and surgical method. METHODS Data were derived from the Swedish Pediatric Cataract Register (PECARE). All children operated on between 1 January 2007 and 31 December 2020 were included. Follow-ups at 1, 2 and 5 years of age were analysed. RESULTS Cataract surgery were performed on 770 eyes belonging to 549 children (n = 282 boys, 51.4%); 327/770 (42.5%) of the children underwent surgery before 3 months of age and 216/770 (28%) before 6 weeks of age. Data on 881 follow-up visits were registered. At the follow up-visits at 1, 2 and 5 years of age, VAO was present in 154/349 (44.1%), 41/323 (12.7%) and 25/208 (12%). The majority of the children with VAO underwent cataract surgery before age 6 months, with a predominance before age 2 months. Primary IOL was implanted in 601/770 (78%) of eyes; 40.8% had an acrylic one-piece lens, 31.8% had a bag-in-the-lens IOL, 21.9% were aphakic and 5.2% had an acrylic three-piece lens. Implantation of a bag-in-the-lens IOL was related to a significantly lower occurrence of VAO compared to other types of IOL, including aphakia (p < 0.0002). CONCLUSION Our results are in accordance with the literature. Primary bag-in-the-lens IOL implantation before 2 years of age seems adequate and safe, with a low occurrence of VAO, and can thus be continued as routine in Sweden.

Abstract
PURPOSE To evaluate the visual outcome of intraocular lens (IOL) exchange for the management of myopic shift in pseudophakic children. METHODS The medical records of children who underwent IOL exchange for myopic shift were examined. The preoperative data, operative details and the postoperative outcome were analyzed. RESULTS Twenty-one eyes (16 patients) were identified. Mean age at cataract extraction was 20 ± 26 months (range, 2-84 months). Twelve patients (6 unilateral, 6 bilateral) had primary IOL implantation. Mean age at IOL exchange was 7.3 ± 3.2 years. Mean spherical equivalent (SE) at IOL exchange was -14 ± 5 D (range, -7 to -21 D): Mean SE at IOL exchange was -13.64 ± 4.99 D, -12 ± 1.53 D, and -15.5 ± 4.7 D in unilaterally pseudophakic cases (8 patients), in the eye that underwent unilateral IOL exchange (3 patients) in bilaterally pseudophakic cases, and in bilateral IOL exchange cases (5 patients), respectively. Mean axial length at IOL exchange was 24 ± 1.3 mm (range, 23 to 27 mm). Following IOL exchange, mean SE was reduced to -2 ± 1.8 D (range, -4 to +2.5 D). An average of three logMAR line improvement in the best-corrected visual acuity was observed in 12/16 eyes of patients for whom pre- and post-exchange visual acuity were available, while visual acuity remained unchanged in 4 eyes. Mean logMAR visual acuity improvement was 0.35 and 0.49 in unilateral and bilateral pseudophakic cases, respectively. CONCLUSIONS IOL exchange is a safe procedure that should be considered to improve visual rehabilitation in pseudophakic patients with myopic shift.

Abstract
PURPOSE The aim of this study was to evaluate the intra- and postoperative complications, especially the risk of visual axis opacification (VAO), following the implantation of the bag-in-the-lens (BIL) intraocular lens (IOL) in infants with congenital cataract operated on before 12 weeks of age. METHODS Infants operated on before 12 weeks of age between June 2020 and June 2021 with a follow-up longer than 1 year were included in the present retrospective study. This was a first-experience cohort of an experienced paediatric cataract surgeon with this type of lens. RESULTS Nine infants (13 eyes) with a median age at surgery of 28 days (range, 21-49 days) were included. The median follow-up time was 21.6 months (range, 12.2-23.4 months). The lens was correctly implanted with the anterior and posterior capsulorhexis edges placed into the interhaptic groove of the BIL IOL in seven of 13 eyes; none of these eyes developed VAO. In the remaining six eyes, the IOL was only fixated to the anterior capsulorhexis edge, and in these cases, an anatomical anomaly of the posterior capsule and/or anterior vitreolenticular interface dysgenesis were observed. These six eyes developed VAO. One eye had a partial iris capture in the early postoperative phase. Otherwise, the IOL remained well centred and stable in all eyes. Anterior vitrectomy was necessary in seven eyes due to vitreous prolapse. One patient with unilateral cataract was diagnosed with bilateral primary congenital glaucoma at 4 months of age. CONCLUSION Implantation of the BIL IOL is safe even in the youngest age group less than 12 weeks of age. Although being a first-experience cohort, the BIL technique is shown to reduce the risk of VAO and the number of surgical procedures.

Abstract
AIM Analysis of age at time of detection and surgery of dense unilateral cataract and investigation of best-corrected visual acuity (BCVA) in a nationwide register-based cohort study, based on the routine of maternity ward eye screening. METHODS Data were derived from the Paediatric Cataract Register (PECARE). All children (n = 54) diagnosed with dense congenital unilateral cataract between January 2007 and September 2014 who had surgery before 1 year of age, and for whom 5-year follow-up records were available, were included. RESULTS The majority, 35/54 (65%), were detected and operated on before age 6 weeks and 30/35 (86%) were referred from maternity wards. Visual acuity (VA) ≥ 0.5 (decimal, 0.3 logMAR) was found in 7/53 (13%) of the cohort at age 5 years; further, 19 children achieved VA ≥ 0.1 (decimal, 1.0 logMAR) (36%) and 19 children VA < 0.05 (decimal, 1.30 logMAR) (36%). Ten-year follow-up records were available for 17/53 (32%) children; 1/17 (6%) achieved VA ≥ 0.5 (decimal, 0.3 logMAR), 4/17 (24%) VA ≥ 0.3-<0.5 (decimal, 0.52-0.30 logMAR), 3/17 (18%) VA ≥ 0.05-0.1 (decimal, 1.30-1.0 logMAR) and 10/17 (59%) VA < 0.05 (decimal, 1.30 logMAR). CONCLUSION A total of 90% of the children were detected with cataract within 100 days of birth and 80% were operated on within this period. This study showed better visual acuity in those treated for dense unilateral cataracts than previously reported in an earlier Swedish cohort study.

Abstract
Purpose To investigate the impact of the pre-operative axial length (AL) on myopic shift (MS) 3 years after primary intraocular lens (IOL) implantation in congenital/developmental cataract patients. Methods A retrospective study of patients who underwent congenital/developmental cataract surgery and primary IOL implantation at age 2-3 years at EENT Hospital was conducted. All patients were followed up regularly for at least 3 years after surgery. Refractive outcomes, including spherical equivalent (SE) and MS, were collected at each follow-up. Results Forty eyes from 40 patients were included. The mean age at surgery was 2.56 ± 0.57 years old, and the mean follow-up time was 3.05 ± 0.22 years. Patients were divided into two groups: Group 1 included 20 patients with longer pre-operative ALs (≥22 mm), and Group 2 included 20 patients with average pre-operative ALs (<22 mm). By the last follow-up, the MS was 2.13 (0.38, 2.63) D in Group 1 and 3.88 (2.85, 5.72) D in Group 2. The post-operative MS in Group 2 was statistically greater than that in Group 1 at 3 years after surgery (P < 0.001). Conclusion In congenital/developmental cataract patients who underwent cataract extraction and primary IOL implantation at age 2-3 years, eyes with longer pre-operative ALs had a slower MS than those with average pre-operative ALs 3 years after surgery. This finding could have implications for the target refraction decision in congenital/developmental cataract surgery.

Abstract
BACKGROUND Congenital cataracts are lens opacities in one or both eyes of babies or children present at birth. These may cause a reduction in vision severe enough to require surgery. Cataracts are proportionally the most treatable cause of visual loss in childhood, and are a particular problem in low-income countries, where early intervention may not be possible. Paediatric cataracts provide different challenges to those in adults. Intense inflammation, amblyopia (vision is obstructed by cataract from birth which prevents normal development of the visual system), posterior capsule opacification and uncertainty about the final trajectory of ocular growth parameters can affect results of treatment. Two options currently considered for children under 2 years of age with bilateral congenital cataracts are: (i) intraocular lens (IOL) implantation; or (ii) leaving a child with primary aphakia (no lens in the eye), necessitating the need for contact lenses or aphakic glasses. Other important considerations regarding surgery include the prevention of visual axis opacification (VAO), glaucoma and the route used to perform lensectomy. OBJECTIVES To assess the effectiveness of infant cataract surgery or lensectomy to no surgery for bilateral congenital cataracts in children aged 2 years and under. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL; which contains the Cochrane Eyes and Vision Trials Register; 2022, Issue 1); Ovid MEDLINE; Ovid Embase; the ISRCTN registry; ClinicalTrials.gov and the WHO ICTRP. The date of the search was 25 January 2022. SELECTION CRITERIA We included all randomised controlled trials (RCTs) that compared infant cataract surgery or lensectomy to no surgery, in children with bilateral congenital cataracts aged 2 years and younger. This update (of a review published in 2001 and updated in 2006) does not include children over 2 years of age because they have a wider variety of aetiologies, and are therefore managed differently, and have contrasting outcomes. DATA COLLECTION AND ANALYSIS We used standard methods expected by Cochrane. Two review authors extracted data independently. We assessed the risk of bias of included studies using RoB 1 and assessed the certainty of the evidence using GRADE. MAIN RESULTS We identified three RCTs that met our inclusion criteria with each trial comparing a different aspect of surgical intervention for this condition. The trials included a total of 79 participants under 2 years of age, were conducted in India and follow-up ranged from 1 to 5 years. Study participants and outcome assessors were not masked in these trials. One study (60 children) compared primary IOL implantation with primary aphakia. The results from this study suggest that there may be little or no difference in visual acuity at 5 years comparing children with pseudophakia (mean logMAR 0.50) and aphakia (mean logMAR 0.59) (mean difference (MD) -0.09 logMAR, 95% confidence intervals (CIs) -0.24 to 0.06; 54 participants; very low-certainty evidence), but the evidence is very uncertain. The evidence is very uncertain as to the effect of IOL implantation compared with aphakia on visual axis opacification (VAO) (risk ratio (RR) 1.29, 95% CI 0.23 to 7.13; 54 participants; very low-certainty evidence). The trial investigators did not report on the cases of amblyopia. There was little evidence of a difference betwen the two groups in cases of glaucoma at 5 years follow-up (RR 0.86, 95% CI 0.24 to 3.10; 54 participants; very low-certainty evidence). Cases of retinal detachment and reoperation rates were not reported. The impact of IOL implantation on adverse effects is very uncertain because of the sparse data available: of the children who were pseudophakic, 1/29 needed a trabeculectomy and 8/29 developed posterior synechiae. In comparison, no trabeculectomies were needed in the aphakic group and 2/25 children had posterior synechiae (54 participants; very low-certainty evidence). The second study (14 eyes of 7 children under 2 years of age) compared posterior optic capture of IOL without vitrectomy versus endocapsular implantations with anterior vitrectomy (commonly called 'in-the-bag surgery'). The authors did not report on visual acuity, amblyopia, glaucoma and reoperation rate. They had no cases of VAO in either group. The evidence is very uncertain as to the effect of in-the-bag implantation in children aged under 1 year. There was a higher incidence of inflammatory sequelae: 4/7 in-the-bag implantation eyes and 1/7 in optic capture eyes (P = 0.04, 7 participants; very low-certainty evidence). We graded the certainty of evidence as low or very low for imprecision in all outcomes because their statistical analysis reported that a sample size of 13 was needed in each group to achieve a power of 80%, whereas their subset of children under the age of 1 year had only 7 eyes in each group. The third study (24 eyes of 12 children) compared a transcorneal versus pars plana route using a 25-gauge transconjunctival sutureless vitrectomy system. The evidence is very uncertain as to the effect of the route chosen on the incidence of VAO, with no cases reported at 1 year follow-up in either group. The investigators did not report on visual acuity, amblyopia, glaucoma, retinal detachment and reoperation rate. The pars plana route had the adverse effects of posterior capsule rupture in 2/12 eyes, and 1/12 eyes needing sutures. Conversely, 1/12 eyes operated on by the transcorneal route needed sutures. We graded the outcomes with very low-certainty because of the small sample size and the absence of a priori sample size calculation. AUTHORS' CONCLUSIONS There is no high level evidence for the effectiveness of one type of surgery for bilateral congenital cataracts over another, or whether surgery itself is better than primary aphakia. Further RCTs are required to inform modern practice about concerns, including the timing of surgery, age at which surgery should be undertaken, age for implantation of an IOL and development of complications, such as reoperations, glaucoma and retinal detachment. Standardising the methods used to measure visual function, along with objective monitoring of compliance with the use of aphakic glasses/contact lenses would greatly improve the quality of study data and enable more reliable interpretation of outcomes.

Abstract
Objective To evaluate safety and postoperative visual outcomes of low-energy femtosecond laser-assisted (FLA) anterior capsulotomy in paediatric cataract surgery. Methods and analysis We report a retrospective single-centre consecutive case series of 51 eyes of 33 paediatric cataract patients with a mean age of 3.22 years (range: 2 months to 13 years) who underwent cataract surgery with FLA anterior capsulotomy, using FEMTO LDV Z8 femtosecond laser (Ziemer Ophthalmic Systems). Anterior laser capsulotomy, phacoaspiration and intraocular lens implantation were performed in all eyes. Both intraoperative and long-term postoperative complications, along with long-term monocular corrected distance visual acuity (CDVA), were assessed during average follow-up period of 32.96 months (range: 13–69 months). Results In 48 out of 51 eyes, a well-sized and well-located anterior capsulotomy was achieved without intraoperative complications. Anterior capsule tears occurred in three eyes; however, they did not extend posteriorly and the intraocular lens were placed in the bags without any further complications. Posterior capsular opacification developed in 45.10% of eyes (23 out of 51) and was subsequently treated with neodymium:yttrium-aluminum-garnet (Nd:YAG) laser capsulotomy. Mean CDVA at final follow-up was 20/40 (range: 20/63 to 20/32) in unilateral cases younger than 12 months, 20/40 (range: 20/1000 to 20/25) in unilateral cases older than 12 months, 20/66 (range: 20/400 to 20/32) in bilateral cases younger than 12 months and 20/40 (range: 20/200 to 20/20) in bilateral cases older than 12 months. Conclusions Paediatric cataract surgery with low-energy FLA anterior capsulotomy is a procedure with long-term safety, resulting in significant improvement in CDVA.

Ophthalmology 2022; 129:997-1003. [PMID: 35595073 DOI: 10.1016/j.ophtha.2022.05.007] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Revised: 05/06/2022] [Accepted: 05/10/2022] [Indexed: 11/18/2022] Open
Abstract
PURPOSE To assess the time course of secondary visual axis opacification (VAO) that led to additional surgery after primary intraocular lens (IOL) implantation in children and to describe further surgical outcomes. Comparison of different lens types. DESIGN Single center, retrospective analysis of children aged 1-14 years who underwent cataract surgery with primary IOL implantation. The surgical technique was either in-bag IOL placement with primary posterior capsulotomy and anterior vitrectomy or bag-in-lens IOL placement. We excluded eyes with visually significant ocular comorbidities. SUBJECTS Total of 135 eyes of 95 children. Of these, 64 had received an acrylic three-piece IOL, 51 an acrylic single-piece IOL, and 20 an acrylic single-piece bag-in-lens IOL. The median ages at surgery were 53 months (IQR 35-75), 52 months (27-65), and 60 months (40-84) in the 3-piece, 1-piece, and bag-in-lens group, respectively. METHODS Analysis of medical records. We used the Kaplan-Meier method and a cox proportional hazards model with pre-defined adjustments for age at surgery, year of surgery, and socioeconomic deprivation (GISD score by postal code) to analyze VAO-free survival by lens type. Patients were invited to attend a clinical visit to achieve longer follow-ups. MAIN OUTCOME MEASURES The rate of survival without VAO that required clearing of the visual axis after cataract surgery with primary IOL implantation. Any other surgical complications. RESULTS The overall median follow-up was 19 months (IQR 3-58). There were 13 cases of VAO, occurring at a median of 10 months (IQR 10-12) after surgery. Of these, 1 eye had a 3-piece in-bag IOL, 10 eyes had 1-piece in-bag IOLs, and 2 eyes had bag-in-lens IOLs. The adjusted hazard ratio was 32.8 (95% CI: 3.3-327, p=0.003) for 1-piece acrylic IOLs and 19.6 (1.22-316, p=0.036) for bag-in-lens IOLs, compared to 3-piece acrylic in-bag IOLs. Two eyes with bag-in-lens surgery (10%) had an iris capture. There was one case of endophthalmitis. We found no cases of postoperative retinal detachment or new glaucoma. CONCLUSIONS Children with secondary visual axis opacification that required a procedure to clear the visual axis generally presented within fifteen months. Opacification rates were lowest when a 3-piece acrylic IOL was used.

Sand MK, Cholidis S, Kristianslund O, Drolsum L. Primary intraocular lens implantation in infants with unilateral congenital cataract operated before 12 weeks of age. Acta Ophthalmol 2022; 100:526-533. [PMID: 35411695 DOI: 10.1111/aos.15155] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Revised: 03/29/2022] [Accepted: 03/30/2022] [Indexed: 11/30/2022]
Abstract
PURPOSE The aim of this study was to report visual outcome and safety after cataract surgery with primary intraocular lens implantation before 12 weeks of age. METHODS Infants with visually significant unilateral congenital cataract having primary IOL implantation in the capsular bag before 12 weeks of age in 2007-2016 were enrolled for a prospective study examination in 2017. The medical records were also reviewed. RESULTS In total, 23 patients with a median age at cataract surgery of 32 days (range, 12-75 days) were included. Seventeen (74%) eyes had persistent foetal vasculature (PFV). After a median follow-up of 6.3 years (range, 1.4-10.9 years), the corrected distance visual acuity was 0.8 logMAR (range, 3.0-0.1 logMAR). All, except one eye, required surgery for visual axis opacification (VAO), with a median of two (range 0-5) additional surgical procedures. Four (17%) eyes developed secondary glaucoma. CONCLUSION Cataract surgery with primary IOL implantation before 12 weeks of age resulted in a high number of VAO operations, and the visual outcome varied considerably, showing the range in outcome for this challenging patient group. Co-existent PFV in these young patients was common. The incidence of secondary glaucoma was similar to other studies, despite the young age at surgery, high percentage of PFV and number of surgical procedures for VAO.

Front Surg 2022; 9:841296. [PMID: 35252341 PMCID: PMC8894437 DOI: 10.3389/fsurg.2022.841296] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Accepted: 01/14/2022] [Indexed: 11/18/2022] Open
Abstract
Objective This study aimed to discuss the effect of phacoemulsification and intraocular lens implantation (PHACO + IOL) combined with trabeculectomy (TRAB) on cataracts and its influence on the corneal endothelium. Methods We selected 120 cataract patients admitted to our hospital from January 2018 to January 2021. According to different surgical methods, they were divided into the control group and the observation group. The observation group was treated with PHACO + IOL combined with TRAB, the control group only received PHACO. The clinical effect, ophthalmic-related parameters, corneal endothelium, complications, the satisfaction of the two groups were observed. Results The total effective rate and total satisfaction rate of the observation group were significantly higher than the control group (P < 0.05). One month after the operation, the vision and central anterior chamber depth of the observation group were higher than those of the control group, and intraocular pressure (IOP) was lower than that of the control group (P < 0.05). One month after the operation, the corneal endothelial cell area and cell density in the observation group were not significantly different from those before operation (P > 0.05). There was no significant difference in the total incidence of complications between the two groups (P > 0.05). Conclusion This study concluded that PHACO + IOL combined with TRAB has a good curative effect in the treatment of cataracts, which can improve the patients' vision and IOP, keep the functional integrity of corneal endothelial cells, and does not increase the occurrence of complications, the patients' satisfaction is high.

Abstract
PURPOSE To report intra- and postoperative surgical outcome using the bag-in-the-lens (BIL) technique in paediatric cataract surgery. METHODS In a retrospective case series, we studied the outcomes of children aged <12 years operated for cataract with the bag-in-the-lens intraocular lens (IOL), with a minimum of 6 months of follow-up. RESULTS Since 2013, 50 eyes in 30 patients <12 years (20 bilateral and 10 unilateral) have been operated at our department with the BIL technique, with a median follow-up time of 33.5 months (range 6-77). Median age at surgery was 49.5 months (4-139). In one case, the IOL luxated through the capsulorhexes to the vitreous, but could be secured and repositioned as planned without further difficulties. Anterior vitrectomy was necessary in one case due to prolapse of vitreous to the anterior chamber during surgery. No other intraoperative complications occurred. Visual axis opacification (VAO) developed in four eyes (8%). So far, only one of these has needed a reoperation with clearing of the secondary cataract. A complete absence of VAO was thus seen throughout the study period in 92%. In two eyes, postoperative iris capture occurred. In both cases, surgical repositioning of the iris was needed. No eyes developed secondary glaucoma during the study period. CONCLUSION The BIL technique seems to be a safe surgical procedure in paediatric cataract, with significantly less complications and need for additional surgery compared with the conventional lens-in-the-bag technique.

Abstract
BACKGROUND Subluxation of the crystalline lens in childhood confronts the surgeon with a dilemma: to operate or to wait and see. Surgery is usually not performed when the subluxation is still limited. However, postponing the surgery increases the surgical difficulty as the capsular bag becomes more difficult to use as a means of support for the intraocular lens (IOL). A large number of children already present a pronounced subluxation at first presentation. In this paper, we describe a technique to optimise centration and fixation of the bag-in-the-lens (BIL) IOL in children younger than 7 years of age with congenital ectopia lentis. METHODS Between October 2019 and December 2020, we performed lens extraction using a combination of bean-shaped segments to support the BIL IOL and a 6 - 0 polypropylene loop fixated at the sclera, following the Yamane technique, for the purpose of centration. We used this technique for seven eyes of four patients. The patients were between 2 and 6 years old; 3 boys and 1 girl. A definite diagnosis of Marfan syndrome was made for two children; for the other two, there was no proven underlying pathology. The luxation was upwards in all cases. The degree of luxation was severe in all eyes. The preoperative refraction values showed high astigmatism values for all eyes, ranging from 6.5 to 11.25 dioptres. Three out of the four patients were myopic, ranging from - 1.5 to - 9 dioptres. RESULTS The surgery could be performed without major complications in all eyes. Good centration was obtained, which remained stable in the postoperative period. Refraction improved with greatly diminished degrees of astigmatism (ranging from 0.25 to 3 dioptres) and myopia (spheres ranging from - 2 to + 1.75 dioptres). CONCLUSION Our novel technique incorporated the BIL technique with the addition of bean-shaped segments and a polypropylene 6/0 suture fixated at the sclera. In this way, we were able to obtain good centration and stability of the implanted IOL, as well as a good refractive outcome in all cases.

Abstract
PURPOSE To evaluate the precision of bag-in-the-lens intraocular lens (BIL IOL) power calculation in different age groups of pediatric cataract patients. SETTINGS Department of Ophthalmology, Justus-Liebig-University Giessen, University Hospital Giessen and Marburg GmbH, Campus Giessen, Giessen, Germany. DESIGN Retrospective nonrandomized consecutive case series. METHODS Pediatric patients diagnosed with cataract and operated with BIL IOL implantation were divided into 4 age groups: Group 1 (0 to 3 months), Group 2 (>3 months, <12 months), Group 3 (12 to 36 months), and Group 4 (>36 months to 17 years). BIL IOL power was calculated with the SRK/T formula. The prediction error (PE) was defined as the absolute difference between the preoperative selected target and postoperative achieved refraction. The impact of age at the time of surgery, axial length (AL), keratometry, and corneal astigmatism on PE was analyzed. RESULTS The study comprised 87 eyes of 56 pediatric patients. The mean and median PEs for the entire group were 1.79 diopters (D) and 1.23 D, respectively. The mean PE in each age group was: 3.43 D in Group 1, 2.14 D in Group 2, 1.60 D in Group 3, and 1.33 D in Group 4. The mean PE in eyes with ALs shorter than 20 mm was 2.67 D, and 1.44 D in eyes with an AL of 20 mm or longer. The mean PE in eyes with corneal radii less than 7.3 mm was 2.45 D, and 1.66 D in eyes with corneal radii of 7.3 mm or more. In the age and AL subgroups, the PE differences were statistically significant (P < .05). CONCLUSIONS The PE was larger in the youngest study group, and it decreased gradually with age and in eyes with ALs shorter than 20 mm. The PE has to be considered during BIL IOL power calculation in children.

Abstract
PURPOSE The aim was to report cumulative incidence and time of onset of postoperative glaucoma in a paediatric early cataract surgery cohort. METHODS Data were retrieved from the Pediatric Cataract Register (PECARE), a prospective register of Swedish cataract operations before 8 years of age. All eyes with surgery between January 2007 and December 2014 and a registered follow-up were included. Cataracts caused by uveitis, trauma or coexisting congenital glaucoma were excluded. Glaucoma was defined as early onset if diagnosed within a year after surgery and late onset if diagnosed later. RESULTS The study included 288 eyes in 207 children (106 girls), 81 with bilateral and 126 with unilateral cataracts, with a mean follow-up of 3.31 ± 1.77 years. Of the 288, 168 (58.3%) had surgery before 3 months of age; most of these 92.3% (155/168) were defined as dense, 208 (72.2%) were below 1 year of age. Cumulative incidence of surgically treated glaucoma among individuals was 23.7% (49/207). Median time to glaucoma onset was 0.91 years (range: 0.05-4.97 years) for eyes. Early-onset glaucoma was found in 98 % (63/64), and late onset in 2% (1/64). CONCLUSION In this paediatric cataract cohort, a majority of eyes had surgery before 3 months of age (58.3%). Secondary glaucoma-onset peaked within the first postoperative year, with a cumulative incidence of 23.7%. Surgery performed after the first month of life, resulted in a lower glaucoma rate. Long-term follow-up will reveal whether the low rate of late-onset glaucoma with early surgery will last, and if so, the consequences.

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.

Abstract
PURPOSE To measure the concentrations of growth factors in the aqueous humor of patients with congenital cataract and to investigate the biological effects of a selected cytokine (fibroblast growth factor 4 [FGF4]) on cell proliferation, migration, and transformation. METHODS In the aqueous humor obtained from 55 eyes with congenital cataract and 55 eyes with age-related cataract, 40 growth factors were screened and selected cytokines were confirmed with enzyme-linked immunosorbent assays. After the addition of various concentrations of FGF4 (0, 2.5, 15, or 50 ng/mL) to the incubation medium, cellular functions were evaluated. RESULTS The concentration of FGF4 was significantly higher in the aqueous humor of patients with congenital cataract than in that of patients with age-related cataract. The human SRA01/04 lens epithelial cell line was treated with FGF4 and the cell proliferation increased significantly both dose- and time-dependently. The wound healing assay and Transwell migration assay revealed a significant increase in the migration capacity of the SRA01/04 cell line treated with 15 or 50 ng/mL of FGF4 compared with that of control cells. The intensity of immunofluorescent staining for α-smooth muscle actin increased significantly in the SRA01/04 cell line when treated with FGF4. Cytoskeletal protein (F-actin) staining showed that changes of cell morphology were induced in primary lens epithelial cells by FGF4. CONCLUSIONS This study provides a comprehensive profile of growth factors in congenital cataract. FGF4 induced cellular changes, and may have utility as a biomarker to predict the formation of visual axis opacification. [J Pediatr Ophthalmol Strabismus. 2020;57(3):159-168.].

Abstract
PURPOSE To determine predictors of secondary glaucoma and poor visual outcome in children undergoing cataract surgery with bag-in-the-lens (BIL)-IOL implantation. METHODS Medical records were retrospectively analysed for children with primary implantation with BIL-IOL during 2009-2013. RESULTS The study included 109 eyes. Median age at surgery was 2.5 years (range 2 weeks-14.1 years), 26.6% being ≤12 weeks of age (= early group). Median follow-up time was 2.8 years (7 months-5.8 years). 15 eyes (13.8%) developed glaucoma, 14 (48.3%) in the early group and 1 (1.3%) in the late group (p < 0.001). Within the early group, mean time for surgery differed significantly. Patients developing glaucoma had cataract surgery at 3.5 ± 1.1 weeks (mean ± SD) and the non-glaucoma patients at 5.7 ± 3.3 weeks (p = 0.024). In the entire cohort, 21 eyes (19.3%) had conditions associated with glaucoma; 57.1% of these developed glaucoma compared to 3.4% without these conditions (p < 0.001). Corrected distance visual acuity (CDVA) (decimal) of ≥0.5 was seen in 50 eyes (48.5%), median 0.63 in the late group and 0.15 in the early group. Glaucoma eyes in the early group (surgery at 3.5 weeks) achieved 0.56 median (range, 0.4-1.0) logMAR, (0.28 decimal) CDVA, whereas non-glaucoma eyes (surgery at 5.7 weeks) achieved 0.89 median (range 0.7-1.6) logMAR (0.13 decimal) CDVA; p = 0.016. Glaucoma development in infants between 5 weeks and 2 years of age was 6.7% (n = 2/30). CONCLUSIONS Comorbidity strongly increases the risk of secondary glaucoma. Surgery during the first month is correlated with better CDVA outcome and glaucoma. After 5 weeks of age, glaucoma rate is low with the BIL-IOL.

Abstract
PURPOSE To report the rate and management of intra- and early postoperative complications of bag-in-the-lens intraocular lens (IOL) implantation technique for cataract treatment in paediatric patients of different age groups. SETTINGS Department of Ophthalmology, Justus-Liebig-University Giessen, University Hospital Giessen and Marburg GmbH, Campus Giessen, Giessen, Germany. DESIGN Retrospective non-randomized consecutive case series. METHODS Ninety eyes of 60 paediatric cataract patients were enrolled to this retrospective non-randomized observational consecutive case series single-centre study. All patients underwent cataract surgery with bag-in-the-lens IOL implantation between January 2008 and December 2018, performed by two experienced surgeons. The entire cohort was divided into four age groups: first - 0-<3 months, second - 3-<12 months, third - 12-<36 and fourth - >36 months-17 years of age. The intra- and postoperative complications were based on the clinical records. The description of management of complications related specifically to bag-in-the-lens IOL technique was based on the 39 consecutive cases operated since 1 Jan 2016 by one single surgeon that were all video documented. The early postoperative period was defined as 12 months after surgery. RESULTS Overall, there were 27 unilateral and 33 bilateral surgical cases of 24 female and 36 male children. The mean age at surgery was 45.25 months (range 1-200 months). The most common intraoperative events were vitreous prolapse and anterior capsule rupture with 28.9% and 13.3%, respectively. Within 12 months of follow-up, five eyes (5.6%) were re-operated because of visual axis reo-pacification (VAR). Intraocular hypertension was diagnosed in seven eyes (7.8%), including two cases that required surgical treatment. In all cases with intra- and early postoperative complications related specifically to bag-in-the-lens technique, it was possible to manage them and successfully implant bag-in-the-lens IOL. CONCLUSIONS Implementation of bag-in-the-lens technique in the treatment of paediatric cataract was associated with a relatively low rate of intra- and postoperative complications, including rare cases of VAR. The correct management of complications related specifically to bag-in-the-lens IOL implantation technique shall to be considered during the learning curve.

Abstract
Purpose: To determine cataract surgeon viewpoints on the efficacy of available therapies/preventatives for two common sequelae of cataract surgery: inflammation and posterior capsular opacification (PCO). Methods: Cataract surgeons practicing worldwide specializing in adult, pediatric and veterinary patients were interviewed between March and August 2018. Results: Ocular inflammation following cataract surgery is treated by either corticosteroids and/or nonsteroidal anti-inflammatories (NSAIDs). Adult and pediatric cataract surgeons are satisfied with current treatments whereas this inflammation is still considered a problem by some in veterinary practice due to its slow resolution. Yttrium-aluminum-garnet (YAG) laser therapy is the PCO treatment of choice for adult cataract surgeons and they are generally pleased with its outcome. However, pediatric cataract surgeons find YAG problematic, especially in patients under 6 years of age, and invasive surgery is often needed to correct PCO/visual axis opacification (VAO). Veterinary ophthalmologists report that YAG is not effective for PCO in animals, especially dogs, due to the density of the fibrotic plaques; 86% of adult and 100% of veterinary and pediatric cataract surgeons surveyed agree that effective anti-PCO therapeutics would improve clinical care. Conclusions: Surgeons treating human patients are pleased with the available treatments for ocular inflammation following cataract surgery, although some veterinary ophthalmologists disagree. The surgeons surveyed agree that PCO/VAO remains an unsolved problem in pediatric and veterinary cataract surgery while the long-term outcome of adult cataract surgery could be improved by additional attention to this issue.
