The outcome of uveal coloboma patients undergoing manual small incision cataract surgery and intraocular lens implantation.

Abstract

Aims: The aim is to study the outcome of uveal coloboma patients undergoing manual small incision cataract surgery (MSICS) and intraocular lens (IOL) implantation.

Subjects and methods: The study included 14 patients with uveal coloboma who underwent small incision cataract surgery and IOL implantation between March 2022 and February 2023. The systemic analysis of preoperative, intraoperative, and postoperative data was done.

Results: The average patient age at the time of surgery was 58.5 years (range 45-74 years). Out of a total of 14 patients, 10 patients had unilateral coloboma and four patients had bilateral presentation. Of these, two patients had only one functioning eye, two had bilateral microcornea, and two had unilateral phacodonesis. Small incision cataract surgery was performed in all cases in one eye. Intraoperative zonular dialysis was noted in five cases where a capsular tension ring was used in two cases and IOL was placed in the bag and an iris-claw was tucked in three cases. Two patients had descemets membrane detachment, where DM repositioning was done with air. None of the cases underwent pupilloplasty.

Conclusions: The cataract patient with congenital iridochoroidal coloboma can be better managed with an MSICS. Although phacoemulsification is the treatment of choice nowadays, a small incision cataract surgery can be considered rescuer in a patient with a hard cataract and microcornea.
