If medically uncontrolled glaucoma with advanced optic nerve head changes in patients with coexisting glaucoma and cataracts is the main indication for surgery, a two-stage procedure (i.e. trabeculectomy first, cataract extraction later) yields better long-term IOP control. If glaucoma is medically controlled with a simple regimen, conjunctiva-sparing cataract surgery may be the treatment of choice. In all other cases of coexisting glaucoma and cataract combined phacoemulsification and trabeculectomy (Glaucoma triple) is preferrable, either performed through a single incision or as two separate procedures in the same session (i.e. trabeculectomy from above, phacoemulsifiaction via clear cornea from temporal).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
