Efficiency of «AB INTERNO» trabeculectomy using the «Trabectome» operating system in patients with primary open-angle glaucoma and cataract

Abstract

ABSTRACT Purpose. To study dynamics of intraocular pressure in open-angle glaucoma and cataract patients after «ab interno» trabeculectomy with the use of the «Trabectome» system. Material and methods. There were operated 52 patients (63 eyes) with open-angle glaucoma. The IOP level was determined using the Maklakov tonometer before operation and 1 week, 2 weeks, 3-5, 6-8, 9-12, 13-26, 27 and more weeks after operation. Results. In patients with cataract and glaucoma the mean IOP before operation was 26.1±3.23mmHg and after operation — 20.5±3.23mmHg in the mean follow-up 173±170.2 days. Conclusions. «Ab interno» trabeculectomy with the use of the «Trabectome» operating system allowed to decrease the IOP by 21.5% in glaucoma patients. It is possible because of microinvasive removal of the trabecular tissue as the main reason for a resistance to the aqueous humor outflow in open-angle glaucoma patients.
