AIM: To compare the visual results and postoperative complications of polymethylmethacrylate (PMMA) and hydrophobic acrylic intraocular lenses (IOLs) in children who underwent cataract extraction with primary IOL implantation. METHODS: This retrospective study included 117 eyes of 63 children with bilateral pediatric cataract undergoing cataract surgery and primary IOL implantation. The patients were divided into two groups, Group I included 58 eyes of 30 patients with PMMA IOLs; Group II included 59 eyes of 33 patients with hydrophobic acrylic IOLs. The clinical features, refraction errors, best corrected visual acuity (BCVA) and surgical complications were compared between two groups. RESULTS: The mean age at the time of surgery was 5.8 (2-12)y and mean follow up period was 40.5 (6-196)mo. Postoperatively, BCVA was ≥0.5 in 80 eyes (68.4%) and this was comparable in two groups. Visual axis opacification was seen in 28 eyes (48.3%) in Group I and 16 eyes (27.1%) in Group II and this difference was statistically significant (P=0.018). Postoperative IOL dislocation and posterior synechia formation were also noted. When all postoperative complications were considered, there were significantly less complications in the acrylic IOL group than PMMA IOL group (P=0.020). CONCLUSION: Pediatric cataract surgery with primary IOL implantation is a safe procedure. Hydrophobic acrylic IOLs may lead to less postoperative complications compared to PMMA IOLs.

Purpose: To compare refractive outcome of posterior Optic Capture versus In-the-bag Implantation of Intraocular Lenses in Pediatric Cataract Surgery. Design: Prospective, randomized and comparative study. Methods: Forty eyes of 25 children (12 males and 13 females) were included in this study with unilateral or bilateral cataracts in the pediatric age during the period between October 2018 to July 2019. These children were diagnosed to have congenital or developmental cataracts. All children underwent cataract surgery and IOL implantation. In our study, all children were divided into two groups: group (A) included 22 eyes that underwent posterior capsulorhexis and anterior vitrectomy with IOL implantation entirely in the capsular bag and group (B) included 18 eyes that underwent posterior capsulorhexis and posterior optic capture of the IOL. Patient demographics, surgical intervention, presenting symptoms, postoperative refraction and follow up of refractive changes for 6 months were recorded. Results: Ten cases were unilateral and fifteen cases were bilateral. The mean age was 5.44 ±3.30 in group (A) while the mean age was 4.26±1.45 in group (B). At 1.5 month, the mean spherical error in group (A) was 2.85 ± 1.41 D  with range from 1 to 6.5D, and the mean spherical error in group (B) was 2.50 ± 1.70 D with range from -0.75 to 3.75 D with no statistically significant difference in both groups. The mean cylindrical error in group (A) was -0.96 ± 1.87 D with range from -3.5 to 2.25D and the mean cylindrical error in group (B) was -1.38 ± 1.79 D with range from -3 to 2D with no statistically significant difference in both groups. At 6 months, the mean spherical error in group (A) was 0.73 ±1.89 D  with range from -4.00 to 3.75D and the mean spherical error in group (B) was 0.00 ± 2.27 D with range from -3.50 to 2.7D with no statistically significant difference in both groups. The mean cylindrical error in group (A) was -1.21± 0.90 D with range from -2.75 to 1.25D and the mean cylindrical error in group (B) was -1.68 ±0.93 D with range from -3.00 to -0.75D with no statistically significant difference in both groups. Conclusion: There was no statistically significant difference between in-the-bag intraocular lens implantation and intraocular lens posterior optic capture in the term of post-operative refraction.  Posterior optic capture helped in preventing posterior capsule opacification (PCO) postoperatively in all cases.

Aim. The aim of the study is to examine changes in the anthropometric and refractive parameters of the eyeball in children with congenital cataracts who have been implanted with various types of IOLs (toric or classic monofocal). Materials and methods. In this work, we retrospectively studied the medical history of 34 children (42 eyes) aged 4 to 15 years, who underwent phacoemulsification of congenital cataracts with implantation of various types of IOLs: toric and simple monofocal. Further, in these groups, by statistical methods, the dynamics of refraction in the first three years after the operation, the incidence of postoperative astigmatism, and its dynamics were assessed. We also assessed the rate of change in the anteroposterior axis of the eyeball, the dynamics of refraction in terms of the total spheroequivalent and maximum visual acuity in 3 years after the operation. Results. According to the results of the study, it was shown that toric IOLs significantly better stimulate the process of emmetropization of the eyeball, and also have a significant tendency to completely eliminate postoperative astigmatism, within 3 years after surgery. However, there were no significant differences in maximally corrected visual acuity between the 2 compared groups. There were also no data showing a significant difference in the more frequent development of myopia in the group receiving the toric IOL. Conclusion. The correct choice and calculation of the IOL remains one of the most difficult tasks in pediatric cataract surgery. New technologies are introduced annually and require constant testing. In this study, we have shown the possibility of using toric IOLs and their positive effects in pediatric cataract surgery and in the prevention and treatment of obscuration amblyopia.

Pediatric Cataract Surgery

A four-year-old female child diagnosed as a case of severe Seasonal Hyperacute Panuveitis (SHAPU) underwent lens-sparing core vitrectomy in her left eye with intravitreal antibiotic and steroid. Patient responded well to treatment and intraocular inflammation subsided. However, three months later, she developed vision impairing dense cataract which also made posterior segment assessment difficult. Lens aspiration with primary posterior capsulotomy and anterior vitrectomy with intraocular lens (IOL) implantation was performed. However, four weeks later, the patient developed occlusio pupillae with iris bombe. She did not respond to medical management so synechiolysis with surgical iridectomy was performed after which a normal depth anterior chamber was attained. Synechia and iris bombe were also relieved, and vision was regained.
