Positive outcomes for 2-year study of OAG standalone procedure

Posted on August 20, 2021

Two-year data demonstrated that the OMNI procedure (OMNI Surgical Systems, Sight Sciences) is a safe and predictable surgical approach to lower IOP pressure in patients with open angle glaucoma (OAG). Long-term data is needed to confirm the results, according to researchers who presented at ASCRS 2021 Annual Meeting.

In the prospective 24-month individual study, the safety and effectiveness of 360-degree viscodilation and the subsequent 360-degree trabeculotomy in 34 eyes from 22 patients with OAG were assessed in practice as an independent procedure. Ocular medical assessment, best corrected visual acuity (BCVA), slit lamp examination, IOP via applanation tonometry, gonioscopy, fundus examination, assessment of nerve abnormalities, imaging of the optic nerve head, C / D ratio, visual field pachymetry, and endothelial cell morphology were recorded. Study also included screening visit, subsequent washout phase (1d-48d), and baseline before the operation. Follow-up visits were planned out to 24-months.

The first results in an observation period of 24 months postop showed IOP was lowered from 24.7 mm Hg preop to 14.5 mm Hg after 1 year and 14.2 mm Hg after 2 years. The mean number of medications was reduced from 1.9 to 0.4 after 1 year and 0.6 after 2 years. The complication rate was low and showed only minor complications (hyphema or lens touch in phakic eyes). No second surgery was needed.
