Abstract
Purpose :
We evaluated the effect of modified trabectome surgery with cataract surgery in reducing intraocular pressure.
Methods :
We retrospectively studied 94 eyes of 56 patients with primary open angle glaucoma, normal tension glaucoma, or pseudoexfoliation glaucoma treated by modified trabectome surgery with cataract surgery. The patients had not previously undergone surgery and had no other ophthalmic history except cataract. The surgical method used differed from the conventional method, in that the anterior chamber was filled with a viscoelastic substance and the inner wall of Schlemm's canal was resected at an angle of 70 degrees in the unperfused state. Intraocular pressure and complications were evaluated preoperatively and 1, 2, and 3 months postoperatively.
Results :
Preoperative intraocular pressure was 16.6 ± 5.4 mmHg, dropping significantly to 13.6 ± 3.9 mmHg at 1 month, 12.8 ± 2.7 mmHg at 2 months, and 13.0 ± 3.2 mmHg at 3 months, postoperatively. There were no serious intraoperative or postoperative complications. Intraocular-lowering eye drop use decreased from 1.6 ± 0.8 agents preoperatively to 0.7 ± 0.7 agents at 3 months postoperatively. The greater the number of preoperative eye drops used, the greater was the effect in reducing intraocular pressure (34.4 ± 20.8% for patients using 3 agents, 24.1 ± 17.7% for patients using 2 agents, and 21.3 ± 13.0% for patients using 1 agent).
Conclusions :
Our method of trabectome microincision with cataract surgery provides good therapeutic results without causing serious complications and requires a shorter operating time than conventional methods. Hence, it is considered as an effective surgical procedure for cataract patients with glaucoma.
