Development of lens surgery in the treatment of primary angle-closure glaucoma

Abstract

The lens plays a crucial part in the etiology of primary angle-closure glaucoma(PACG). The changes in the thickness and position of the lens have been related to common structural deviations observed in PACG eyes such as: shallow anterior chamber, pupillary block and crowded anterior chamber angle. Lens extraction has long been used to treat PACG, which combined with anti-glaucoma surgeries remains a commonly employed therapy. This article aims to summarize the medical outcome and role of phacoemulsification with or without anti-glaucoma surgeries in the treatment of PACG.
