Abstract

BACKGROUNDː Glaucoma surgeries result in substantial intaocular pressure (IOP) reductions but associated with significant risks. Recently, new surgical techniques needed to achieve more IOP reduction with satisfactory safety profile.

Aim of work: Compare phacoemulsification and goniotomy with the Kahook Dual Blade versus phacoemulsification with subscleral trabeculectomy showing their impact on glaucoma surgery.

Methodology: This prospective, randomized, comparative study included 40 patients above age of 40 of both genders diagnosed as primary open angle glaucoma. The patients were assigned into two equal groups: using the Kahook Dual Blade and traditional sub scleral trabeculectomy. Evaluation of visual acuity and measurement of IOP were the main outcomes.

RESULTSː Traditional sub scleral trabeculectomy group had showen statistically significant lower IOP at first week (P=0.01) and at six month (P=0.03 without statistical difference regarding medication requirements postoperative (P > 0.05) and in the success or failure rates (P > 0.05), in comparison to Kahook Dual Blade group. However, both groups show significantly difference compared to baseline values rgerding IOP, medication requirements postoperative and complications incidence(P<0.001).

CONCLUSIONSː Phaco-Kahook goniotomy was proved to be effective in treatment of glucoma with high success rates as phaco-trabeculectomy and have potential advantagesas like easy technique and it has excellent safety profile but without difference in reducing antiglaucoma medications and postoperative complication when compared with phaco-trabeculectomy .Also, Phaco trabeculectomy has more effect on IOP reduction after six month.
