Purpose: To evaluate the effect of cataract surgery on disease activation and visual outcomes in neovascular age-related macular degeneration (AMD).Methods: In this retrospective case-control study, study arm consisted of neovascular AMD patients, who underwent phacoemulsification surgery. Patients did not have any disease activation at least 6 months before the inclusion, and all had at least 12-month follow-up thereafter. Control group consisted of phakic patients, who did not undergo eye surgery during the study period. Primary outcomes were the presence of the disease activation and the change in best-corrected visual acuity (BCVA).Results: A total of 114 neovascular AMD patients [55 (48%) in exudative group and 59 (52%) in disciform group] were included. Preoperative logMAR BCVA was significantly improved after cataract surgery [0.8 (0.6-1.0) vs. 0.4 (0.4-0.7), P < 0.001 in exudative AMD; 1.85 (1.1-1.9) vs. 1.09 (0.8-1.9), P = 0.001 in disciform scar], but this improvement was not maintained during the study period in patients with both exudative AMD and disciform scar [0.6 (0.3-1.1), P = 0.313 in exudative AMD; 1.30 (1-1.9), P = 0.03 in disciform scar]. The incidence of disease activation was not statistically significant between surgery and control groups in patients with exudative AMD [5 (25%) patients in surgery group and 8 (22%) patients in the control group, P = 0.886, Cox proportional hazards regression analysis]. In disciform scar, disease activation was observed in 4 (17%) patients in the surgery group; however, no patient in the control group had disease activation (P = 0.009, HRs could not be estimated, 95% CI 0.001-43.49, Cox proportional hazards regression analysis).Conclusion: Cataract surgery has benefit on early postoperative visual improvement in patients with neovascular AMD. The incidence of disease activation was not affected after surgery in exudative AMD. [ABSTRACT FROM AUTHOR] |
