Immediate sequential (ISBCS) compared with delayed sequential (DSBCS) bilateral cataract surgery does not appear to result in worse postoperative best-corrected visual acuity (BCVA) or refractive error, or with an elevated complication risk, suggests a recent study.
There are significant differences in intakes of vitamins C and E, beta-carotene, folate, and vegetables between patients with late-stage age-related macular degeneration (AMD) and healthy controls, according to a recent study, which provides a better understanding of the nutritional intake of patients presenting with advanced AMD.
