Abstract

Purpose: To assess the results of phacoemulsification_IOL combined goniosysnechialysis for failed trabeculectomy in primary angle-closure glaucoma. Patients and Methods: Primary angle-closure glaucoma eyes who has failed trabeculectomy. Clinical interventional  study was conducted from January/2021 to 12/2022 at Glaucoma Department. Viet Nam National Eye Hospital. Results: Preoperative characteristics: females:males ratiowas 13:3. The mean age was61.15±8.45 year old. Average time after Trabeculectomy was 41.47±43.95 months, Visual acuity (VA)and IOP are improved remarkably after surgery. IOP was reduced significantly at all time pointsfrom 28.79 ±5.61 mmHgat baseline to 15.15±3.46 mmHg at 6 months after surgery. Preoperative Log MAR VA was 1.71±0.87, which has been improvedto 0.77±0.44 at 6 months with p<0.001. Number of IOP lowering medications was  decreased from 2.56±0.63 to 0.31±0.87 with p<0.001. Thecomplete successrate was 87.5 %. Preoperatively,anterior chamber angle were almost completely closed. After surgery, angles were widened to grade 3-4 Shaffer in almost all cases except onlyone case where the angle closure has recurred. Hyphema is the most common complication which happened in 50% cases, which, luckily, was transient and responded well to treatment. Conclusion: Phacoemulsification/ GSL proved to be safe and effective in PACG eyes with previously failed trabeculectomy.
