Long-term visual acuity and its predictors after cataract surgery in patients with uveitis

Abstract

Purpose: To analyze the outcomes of phacoemulsification and posterior intraocular lens (IOL) implantation in patients with uveitis and to determine factors responsible for poor visual outcome.

Methods: The records of 155 patients (180 eyes) with uveitis who had phacoemulsification and IOL implantation between August 2001 and March 2008 were examined retrospectively. Best-corrected visual acuity (BCVA) was recorded at the immediate preoperative visit and at follow-up examinations every 3 months. At each postoperative visit, a complete ophthalmologic examination was performed. The postoperative visual outcomes and complications were analyzed. Univariate regression analysis was done to determine risk factors for poor visual acuity during follow-up.

Results: The mean follow-up was 31.4 months (range 3-78 months). An underlying systemic disease was present in 70 (45.2%) patients (82 eyes, 45.6%). The mean preoperative logMAR BCVA was 1.13 +/- 0.62 (95% CI: 0.85-1.02) and increased to 0.42 +/- 0.57 (95% CI: 0.32-0.59) at last medical visit (p < 0.001). A total of 107 eyes (59.4%) had postoperative complications including posterior capsular opacification, newly developed macular edema, recurrence of uveitis, macular epiretinal membrane, and deposits on the IOL surface. Preoperatively observed macular lesions was the factor most strongly associated with poor visual outcome after cataract surgery (odds ratio: 5.43; 95% CI: 3.41-7.34; p < 0.001). Anterior segment pathologies, age at surgery, etiology of uveitis (idiopathic, uveitis associated systemic disease), and gender did not influence visual rehabilitation after surgery (p > 0.05).

Conclusions: The outcomes of phacoemulsification and IOL implantation in patients with uveitis were satisfactory. Patients with observed preoperative macular lesions are at risk for poor visual outcome.
