Combined small incision cataract surgery and trabeculectomy on intra ocular pressure outcome

Trabeculectomy is a gold standard filtration procedure in the management of glaucoma. However, small incision cataract surgery with trabeculectomy is the combined surgical procedure for the management of coexisting glaucoma and cataract. The final success rate related to minimizing intraocular pressure (IOP) depends on the follow-up duration and assessment criteria. This study was aimed to evaluate the long term control of intraocular pressure and morphology of bleb in cases undergoing small incision cataract surgery with trabeculectomy. One hundred cases diagnosed with moderate or severe glaucomatous damage with cataract above 32 years were recruited. Postoperative follow up was done from day 1 to 12 months, to evaluate the intraocular pressure (IOP), bleb morphology and postoperative complications. In PAOG, 61.3% cases had good control and 60% cases had poor control of postoperative IOP. In PACG, 32% cases had good control and 28% cases had poor postoperative IOP control. In the overall success, the qualified success rate was 63% and the complete success rate was 97%. Cases with early postoperative IOP of >10mmHg on 5th day or >13mmHg on 10th day is associated with poor control of intraocular IOP at the end of 12th month. Small incision cataract surgery with trabeculectomy is an effective procedure in reducing the intraocular pressure.
