Visual rehabilitation and intraocular pressure control after one site phacotrabeculectomy - an urban uni-center cross-sectional survey of Karachi, Pakistan

ABSTRACT

Cataract extraction and anti-glaucoma procedure together are regarded as an appropriate surgical intervention for co-existing uncontrolled glaucoma and visually significant cataract. Variety of surgical phacotrabeculectomy techniques have been proposed to reduce the frequency of complications and to solve the conflicting problems of water tight cataract incision and patient filtering glaucoma procedure. Our study will determine the visual recovery and intraocular pressure [IOP] control after single sitting phacoemulsification and trabeculectomy. The study is a comparative cross-sectional study. The participants included 50 patients randomly selected from out door patient department of Kulsoom Bai Valika Social Security SITE hospital, a tertiary care center. Routine one site phacotrabeculectomy was performed in all 50 patients and were followed over a period of 24 weeks. The data was entered on Statistical Package for Social Sciences [SPSS] Version 16 and analyzed. The pre-operative intraocular pressure [IOP] was 27.0 +/- 3.7, while the post-operative intraocular pressure [IOP] was 16.04 +/- 0.75 [p-value <0.0001]. The visual acuity which was evident [6/18] in 86% preoperatively and was reduced to 12% postoperatively [p-value <0.0001] while [6/9 - 6/12] visual acuity in the participants were 10% preoperatively and was improved in 80% postoperatively [p-value <0.0001]. Where as visual acuity [6/6] the participants were 4% preoperatively and 8% postoperatively [p-value <0.0001]
