[Laser suture lysis following trabeculectomy]

Trabeculectomies with tightly sutured scleral flap was performed on 49 eyes of 45 patients with angle closure or open angle glaucomas, the experimental group, of which 41 eyes underwent laser suture lysis subsequently. After a mean period of follow-up 14.7 months (12-36 months), the average intraocular pressure was decreased from pre-operative 5.93 kPa (44.5 mmHg) to post-operative 1.96 kPa (14.7mmHg). The experimental group of patients was compared with the control group, 41 eyes of 39 cases at the same period randomly undergoing trabeculectomy without laser suture lysis. The control rate of intraocular pressure is higher (89.8%:73.2%) and the incidence of ocular complications (such as, shallow anterior chamber, choroid detachment, hyphema, lens opacity) is significantly lower in the former group, showing that trabeculectomy with following laser suture lysis is a safe and effective anti-glaucoma surgery. The advantages, points for attention and experiences of laser suture lysis have been introduced in the paper.
