New AREDS Study Concludes Age-Related Macular Degeneration Not Made Worse by Cataract Surgery

A study published in the February issue of the journal Ophthalmology by a research team at the National Eye Institute (led by Emily Chew MD, deputy director of the Division of Epidemiology and Clinical Research at the Institute), concludes that cataract surgery doesn’t hasten vision loss in people with age-related macular degeneration (AMD). The study analyzed data from 4,577 participants (8,050 eyes), aged 55 to 81 years, who participated in the Age-Related Eye Disease Study (AREDS).
