Effects of cataract surgery in Japanese patients with neovascular age-related macular degeneration

Abstract

Purpose: To investigate the effects of cataract surgery in Japanese patients with neovascular age-related macular degeneration (nAMD). Methods: The primary endpoint in this prospective, observational study was patient satisfaction at 6 months after cataract surgery in patients with nAMD. Secondary endpoints comprised changes in best-corrected visual acuity (BCVA), M-chart score, central retinal thickness (CRT), AMD status, and number of AMD treatments. All examinations were performed before surgery, and at 1, 3, and 6 months postoperatively. Results: Fifty patients (52 eyes) were included in this study (32 men; mean age, 76.1 ± 7.1 years). Thirty-nine patients (75.0%) reported satisfaction with cataract surgery. BCVA significantly improved at all postoperative timepoints (all p < 0.0001), whereas differences in M-chart scores were not statistically significant. The number of eyes with BCVA ≤ 0.3 logarithm of the minimum angle of resolution (logMAR) increased from 21 to 38; however, CRT did not change. The number of AMD treatments did not change during follow-up. All questionnaire scores showed postoperative improvement. Univariate and multivariate analyses revealed that final BCVA ≤ 0.3 logMAR was significantly associated with patient satisfaction. Conclusion: Cataract surgery significantly improved vision in Japanese patients with nAMD, without affecting AMD status. Patients were satisfied with cataract surgery, especially with respect to improvement of distance vision. [Figure not available: see fulltext.]
