Phacoemulsification in phacomorphic angle closure: Our experience.

Abstract

To evaluate intraocular pressure (IOP) control, visual prognosis, and complications following phacoemulsification in eyes with phacomorphic angle closure of <10 days' duration. Prospective, nonrandomized interventional consecutive case series included all patients with phacomorphic glaucoma who presented between November 2020 and November 2021. All patients underwent slit-lamp biomicroscopy, applanation tonometry, and gonioscopy of the other eye. Phacoemulsification with IOL implantation under topical anesthesia was performed in all cases. A complete ophthalmic examination was done at each follow-up visit. A total of 50 eyes with phacomorphic glaucoma were included in this study. The preoperative mean IOP was 41.12 ± 8.20 mmHg and the mean IOP at last visit was 13.84 ± 2.08 mmHg. There was a statistically significant difference between IOP at presentation and IOP at last follow-up (P < 0.001) (Wilcoxon Signed-Ranks Test). There was no requirement of long-term anti-glaucoma medications in any patients. No significant intraoperative complications were noted. The final postoperative best-corrected visual acuity was 6/12 or better in 32 patients. Sixteen eyes had corneal edema and 20 eyes had anterior chamber inflammation on postoperative day one that resolved with standard medical therapy. Phacoemulsification is safe and effective in controlling IOP and achieving good functional visual acuity with minimal complications in the management of phacomorphic glaucoma in expert hands. Our study also lays emphasis on public awareness, early detection, and management of advanced cataract, so that the incidence of this potentially blinding entity can be reduced.
