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. Keywords Patient satisfaction . Age-related macular degeneration . Cataract surgery .

Key messages Cataract surgery is effective for the improvement of visual function, especially distance vision, in Japanese patients with nAMD. Patients with nAMD were satisfied with the results of cataract surgery without a significant increase in metamorphopsia. AMD status was not affected by cataract surgery.

Introduction In 2019, the United Nations reported that there were 703 million persons aged ≥ 65 years worldwide; of these, 261 million were in southeastern Asia [1]. With regard to visual health, aging is an important factor in the onset of both cataracts and age-related macular degeneration (AMD).

Cataracts are the leading cause of blindness worldwide, while AMD is the third leading cause [2]. Cataracts gradually interfere with a patient’s vision [2, 3], while neovascular AMD (nAMD) causes sudden vision loss. Symptoms of nAMD include
