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.
