Study of visual outcome and complications of primary and secondary retropupillary iris claw lens implantation in absence of adequate capsular support

Abstract

This study was conducted to assess and compare the visual outcome and complications of retropupillary iris claw lens implantation in absence of adequate capsular support.This prospective, comparative, intervention, was conducted. All the patients who reported ophthalmology indoor department were divided into two groups. In 1 group patients with IMSC/MSC/Traumatic cataract/Repaired corneal tear with traumatic cataract/Subluxated IOL in which primary retropupillary iris claw lens implantation was done in the department of Ophthalmology through SICS/Phacoemulsificstion were categorised. In 2 group patients with Aphakia in which cataract surgery was performed through SICS/Phacoemulsification and were left aphakic due to PCR in the department of Ophthalmology, JLN Medical College & Hospital and outside indoor patients at various ophthalmology centres. In primary RPICL in 23(76.7%) patients found to be BCVA between 6/36 to 6/18 and in secondary RPICL 26(86.7%) patients found to be BCVA between 6/12 to 6/6. In primary cases RPICL ovalisation of pupil in 6(20%), tilted IOL with raised IOP in 3(10%) optic capture in 3(10%), iridodialysias in 3(10%), bullous keratopathy in 3(10%). In secondary RPICL optic capture in 2(6.67%), CME with raised IOP in 1(3.33%), ovalisation of pupil in 1(3.33%) was found. Results of present study suggest that secondary cases (group II) showed better visual outcome and lesser complications when compared with primary cases (group I) after retropupillary iris claw lens implantation.
