Comparison of Fixation Suture Type in Glaucoma Surgery

The aim of the study is to compare the effectiveness and safety of two types of intraoperative eye fixation: for the superior rectus muscle and traction suture in the peripheral cornea. This is a prospective randomized trial with a 6 month follow-up period, which covers patients with open angle glaucoma qualified for combined glaucoma procedure (phacotrabeculectomy). In I group, the intraoperatively fixation in the peripheral part of the cornea is used, in II group the bridle suture for the superior rectus muscle is performed.

The way of the intraoperatively fixation may have some impact for postoperative results of the level of intraocular pressure (IOP), visual acuity (BCVA) and the incidence of upper eyelid ptosis was determined as a post-operative MRD (margin reflex distance) ≥2mm.
