Abstract

Glaucoma is the second most common cause of blindness in the world and affects almost 60 million people globally. Trabeculectomy is the most commonly performed surgical procedure for glaucoma. It is a filtering procedure which lowers the intraocular pressure by creating a new channel for aqueous out flow between the anterior chamber and sub-conjunctival /sub-tenon space. Newer technique of sutureless filteration surgery controls the intraocular pressure and is a tremendous breakthrough in reducing postoperative astigmatism. The procedure is quick, requires minimal tissue handling and can be done alone or can be successfully combined with phacoemulsification. The surgery gives the convenience of performing the procedure from a very small opening and has the benefit of being sutureless, thus, keeping in mind the induced astigmatism to minimum. It also promotes very early visual rehabilitation and the results are comparable to the conventional trabeculectomy.
