Management and Visual Outcome in Patients of Lens-Induced Glaucoma at a Tertiary Care Hospital

Abstract

A BSTRACT Lens-induced glaucoma (LIG), a sight threatening secondary glaucoma disease, prevalent in India, requires early management for restoring vision and preventing blindness. Despite its clinical significance, limited data exists regarding visual outcomes following current management approaches in phacomorphic and phacolytic LIG. Thus, we compared visual outcomes and intraocular pressure (IOP) control following surgical management in these two LIG subgroups. This prospective observational study was conducted over a period of 18 months (November 2023 to May 2025) at the Department of Ophthalmology at a tertiary care center. A total of 100 patients of LIG were included and demographic data, clinical presentation, management and outcomes, including best-corrected visual acuity (BCVA), IOP and complications at the end of 6 weeks, were recorded and analyzed. Intraoperative complications were similar between phacomorphic and phacolytic LIG groups, with posterior capsule rupture occurring most frequently (9.3% vs. 14.29%). Overall, surgeries were uneventful in 89.53% and 85.71% of cases, respectively. Postoperatively, corneal edema was the most common complication. IOP significantly improved, with 86% of patients achieving values within the normal range following treatment. BCVA showed improvement, with 41.86% of phacomorphic and 57.14% of phacolytic patients reaching 6/6–6/12. Symptom duration strongly correlated with both IOP levels and the severity of optic disc changes. The significant relationship between symptom duration, IOP, and optic disc changes highlights the necessity for prompt treatment, as prolonged symptoms adversely affect visual prognosis.
