Standalone Canaloplasty and Trabeculotomy Using the OMNI Surgical System: A Subgroup Analysis from the American Academy of Ophthalmology IRIS

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: To characterize clinical outcomes of canaloplasty and trabeculotomy using the OMNI Surgical System (Sight Sciences) as a standalone procedure in primary open-angle glaucoma (POAG) subgroups (phakic, pseudophakic; mild, moderate, severe disease). Design: Retrospective, observational cohort study utilizing the American Academy of Ophthalmology (Academy) IRIS Methods: Patients with POAG undergoing standalone OMNI surgery with known laterality between January 2018 and December 2021 and followed for a minimum of 6 months and up to 36 months were included. Analyses divided the cohort into mild, moderate, and severe glaucoma subgroups (International Classification of Disease-10 coding), and lens status (phakic and pseudophakic) subgroups. Outcomes included changes in intraocular pressure (IOP) and glaucoma medication class use. Results: Data from 220 eyes of 187 patients were analyzed. Mean IOP reductions from baseline were clinically and statistically significant at every time point across disease severity groups; mild, 5.5-9.4 mmHg (p < 0.0026); moderate, 5.3-7.4 mmHg (p < 0.0001 at all time points); severe, 5.8-7.6 mmHg (p < 0.0004). Mean IOP reductions were 5.1-7.4 mmHg in phakic eyes and 5.8-6.7 mmHg in pseudophakic eyes; p < 0.0001 all time points, both subgroups. Mean medication reductions from baseline were clinically and statistically significant at month 6 and month 12 in the mild and severe groups, and insignificant at all other time points in the three groups. Medication reductions averaged 0.3-0.4 in phakic eyes (non-significant) and statistically significant reductions of 0.4-0.6 in pseudophakic eyes (months 6, 12, and 18 [p < 0.01]), with non-significant reductions (0.3-0.4 medications) at later time points. Conclusion: In this study, standalone OMNI surgery significantly decreased IOP for up to 3 years regardless of disease severity or lens status. This procedure may be considered for phakic or pseudophakic patients with all stages of glaucoma whose therapeutic goals fall within the ranges achievable with standalone surgery.
