Long-term outcomes of small-incision cataract surgery in patients with uveitis.

Abstract

To evaluate the long-term outcomes of manual small-incision cataract surgery (MSICS) in eyes with uveitis. Patients who underwent MSICS for uveitic cataract from 2009 to 2019 were retrospectively evaluated. Visually significant cataract and presence of less than five cells per high-power field in the anterior chamber for a minimum of 3 months were the prerequisites for surgery. Patients with follow-up less than 9 months were excluded. After exclusion, 283 eyes of 264 patients were evaluated. The mean age of patients was 44.3 ± 11.3 years. The mean follow-up duration was 22 ± 11.5 months. The mean surgical time was 11.2 ± 3.2 min. One hundred and seventy-two eyes (60.8%) had anterior uveitis, 78 (27.5%) had posterior uveitis, and 33 (11.7%) had panuveitis. At the final follow-up, 253 eyes (88.4%) had corrected distance visual acuity (CDVA) better than 0.6 log of minimum angle of resolution (LogMAR) unit. The final endothelial cell counts were significantly (analysis of variance [ANOVA], P = 0.001) lower in eyes with human leukocyte antigen (HLA)-B27-associated uveitis and in eyes with idiopathic anterior uveitis. Patients on systemic corticosteroids had significantly better (P = 0.031) final visual acuity than those without preoperative corticosteroids. Recurrent uveitis (43.8%), Posterior capsule opacification (PCO) (19.4%), glaucoma (8.5%), cystoid macular edema (CME; 13.5%), and Epiretinal membrane (ERM) (5.6%) were the frequent complications. A significantly worse (ANOVA, P = 0.001) visual prognosis was seen in patients with Vogt-Koyanagi-Harada disease (VKH), sarcoidosis, acute posterior multifocal placoid pigment epitheliopathy (APMPPE), and serpiginous choroiditis. MSICS is safe in most cataracts due to uveitis and results in improvement in CDVA at 9 months. Posterior capsule opacification, macular edema, persistent uveitis, etiology of uveitis, and use of preoperative steroids significantly influenced the visual outcome.
