Canaloplasty and trabeculotomy ab interno with the OMNI system combined with cataract surgery in open-angle glaucoma: 12-month outcomes from the ROMEO study.

PURPOSE: To provide safety and effectiveness outcomes 12 months postsurgically for sequential canaloplasty and trabeculotomy with the OMNI system combined with cataract surgery in mild-to-moderate open-angle glaucoma (OAG). SETTING: Eleven ophthalmology practices and surgery centers located in 8 U.S. states. DESIGN: Retrospective, multicenter, single arm. METHODS: Twelve surgeons contributed 81 patients meeting eligibility criteria: OAG, 12-month follow-up, and medicated intraocular pressure (IOP) 36 mm Hg or less on 4 or less medications preoperatively. Analysis was stratified by baseline IOP: more than 18 mm Hg (Group 1) and 18 mm Hg (Group 2) or less. Success was defined as proportion with 20% reduction or greater in IOP or IOP between 6 and 18 mm Hg (inclusive) and on the same or fewer medications without secondary surgical intervention (SSI). Other endpoints included mean IOP and medications at 12 months. Safety included corrected distance visual acuity and adverse events (AEs). RESULTS: Of the 81 patients included, primary success was met by 79% in Group 1 and 81% in Group 2. The mean IOP was reduced in Group 1 (21.9 to 15.1 mm Hg, P < .0001) and remained controlled in Group 2 (14.1 to 13.4 mm Hg, P = .3177). Medications went from 2.0 ± 1.3 to 1.1 ± 1.1 in Group 1 and from 1.6 ± 1.3 to 0.9 ± 1.2 in Group 2. AEs were typical for cataract or angle surgery: mild inflammation (11%), IOP spikes (5%), and hyphema (4%). Four patients (5%) required an SSI. CONCLUSIONS: The OMNI system provided effective IOP reduction, sustained IOP control, and meaningful medication reduction for up to 12 months postoperative.

Canaloplasty and Trabeculotomy with the OMNI System in Pseudophakic Patients with Open-Angle Glaucoma: The ROMEO Study.

PURPOSE: Provide outcomes up to 12 months postsurgically for sequential canaloplasty and trabeculotomy with the OMNI surgical system (Sight Sciences, Inc) in pseudophakic patients with mild to moderate open-angle glaucoma. DESIGN: Retrospective, multicenter, single-arm study conducted at 10 multi-subspecialty ophthalmology practices and surgery centers located in 7 states (Arkansas, California, Kansas, Louisiana, Missouri, New York, and Texas). PARTICIPANTS: Eligible patients were pseudophakic, with mild/moderate open-angle glaucoma, 12-month follow-up, and medicated intraocular pressure (IOP) ≤36 mmHg on ≤4 medications preoperatively. One eye per patient was enrolled. METHODS: Institutional Review Board approved. All available cases meeting eligibility criteria were enrolled. Analysis of secondary end points was stratified by baseline (BL) IOP (>18 mmHg in group 1 and ≤18 mmHg in group 2) recognizing that treatment goals differed depending on BL IOP. MAIN OUTCOME MEASURES: Primary success was defined as the proportion of patients with ≥20% reduction in IOP from BL or IOP between 6 and 18 mmHg (inclusive) and on the same or fewer medications without secondary surgical intervention (SSI). Other effectiveness end points included mean IOP and number of medications at 12 months. Safety end points were best-corrected visual acuity (BCVA), adverse events (AEs), and SSIs. RESULTS: Forty-eight patients were enrolled, 24 in each group. Primary success was met by 73%. Mean IOP was reduced in group 1 (21.8 to 15.6 mmHg, P < 0.0001) and remained controlled in group 2 (15.4 to 13.9 mmHg, P = 0.24). Medications went from 1.7 ± 1.3 to 1.2 ± 1.3 (P = 0.024) in group 1 and from 2.0 ± 1.3 to 1.3 ± 1.3 (P = 0.003) in group 2. Adverse events were typical for the patient population undergoing angle surgery. Those reasonably related to the procedure were mild inflammation (13%), IOP spikes (6%), hyphema, corneal edema, and BCVA loss (all 4%). Five patients (10%) required an SSI. CONCLUSIONS: The sequential combination of canaloplasty followed by trabeculotomy performed as stand-alone procedures using the OMNI system in pseudophakic patients with open-angle glaucoma provides effective IOP reduction or sustained IOP control and meaningful medication reduction for up to 12 months postoperatively.
