Filters are a common name for a type of glaucoma surgery called trabeculectomy, where an outflow pathway is created for intraocular fluid. The goal of this surgery is to control intraocular pressure. The biggest concern with modern cataract surgery in the presence of filters, is that inflammation during and after cataract surgery can diminish the function of the filtration site. Your surgeon should aggressively address postoperative inflammation and carefully monitor your intraocular pressure.
