Outcomes of cataract surgery in patients with Human Immunodeficiency Virus infection in a developing country.

Abstract

To report the outcomes of cataract surgery in patients with Human Immunodeficiency Virus (HIV) infection. Setting Tertiary care ophthalmic hospital DESIGN: Retrospective study METHODS: This study included all eyes of patients with known HIV infection undergoing cataract surgery with a minimum follow-up of 6 months between January 2017 and December 2020. Patients who underwent combined surgeries and pediatric patients were excluded from analysis. Data were retrieved from electronic medical records and we documented demographics, history, detailed anterior and posterior segment examination, pre-operative grade and type of cataract, type of surgery done, its complication and post-operative course. All these parameters were recorded at the baseline visit and at 1 month and 6 months postoperatively. One hundred and twenty nine eyes of 107 HIV infected patients that underwent cataract surgery were evaluated. Mature cataract was seen in 31% of the eyes. Features of HIV related uveitis/retinitis were seen in 21 (16.2%) eyes. Phacoemulsification was performed in 44 (34.1%) eyes while manual small incision cataract surgery (MSICS) was done in 85 (65.9%) eyes. Intra-operative complications were encountered in 4 (3.1%) eyes. At the final follow-up, there was a significant improvement in median corrected distance visual acuity (CDVA) from LogMAR 1.08 (5/60) at baseline to LogMAR 0 (6/6) at 6 months follow-up. Patients with HIV infection usually present early and with advanced cataracts. Visual outcomes after cataract surgery are generally good but affected by presence of prior HIV related uveitis or retinitis.
