Abstract

To decrease astigmatism in cataract as well as trabeculectomy different modification have been tried in the incision shape, size and sites. Sutureless trabeculectomy and ‘W’ shaped incision trabeculectomy is also few of them. A randomized, prospective, interventional and comparative clinical trial carried out on 39 eyes of 39 patients with primary open angle glaucoma (POAG) with coexisting cataract. The aim of the study was to compare the astigmatism of combined manual Small-Incision Cataract Surgery (SICS) and posterior chamber intraocular lens (PCIOL) implantation with Trabeculectomy by sutureless  [group A] versus combined SICS and PCIOL implantation with trabeculectomy using ‘W’ shaped incision technique [group B]. Surgically induced ATR Astigmatism in group A was 1.57±0.37D while in group B was 1.28±0.39D [p=0.028]. None of the patient in either group had surgically induced WTR astigmatism. Due to the high mechanical stability of the W-shaped incision and suture, comparatively less induced astigmatism was seen in combined surgery done with W- shaped incision in comparison to combined SICS with sutureless trabeculectomy. Both the procedures are safe as none of the patient in any group had any major complication or sight loss due to surgery
