Cataract surgery in AMD patients

Abstract

Cataract and age‐related macular degeneration (AMD) are leading causes of visual loss and they occur in the similar age group, thus co‐existence of both diseases is real clinical problem and challenge. Theoretical mechanisms considered to be involved in possible relations between cataract surgery and AMD progression include blue light toxicity and the role of post‐operative inflammation. None of these mechanisms was found to play a role in clinical conditions. Some earlier a recent population‐based studies reported an increased risk of late AMD after cataract surgery; however, this was not confirmed by recent cross‐sectional studies (clinical‐based) from South Korea and Australia. Systematic reviews and meta‐analyses reported a moderate quality of evidence to suggest that VA was better by approximately 7 letters in eyes with AMD that underwent cataract surgery vs. eyes with AMD that did not undergo cataract surgery for up to 12 months after surgery and the same quality of evidence did not find an increased risk of progression to exudative AMD for at least 12 months after surgery. The risks and possible advantages of cataract surgery in visual rehabilitation of wet and dry AMD patients will be discussed.
