Two-Year Outcomes of Goniotomy After Failed Surgery for Glaucoma: A Multicenter Study.

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 evaluate the 2-year outcomes of goniotomy (GT) in patients with prior failed glaucoma surgery. Design: A prospective, observational multicentered study. Participants: Patients who underwent GT after previous failed glaucoma surgery. Methods: Patients were enrolled from May 2021 to October 2022. They underwent comprehensive ophthalmic examination, including medical history review, slit lamp examination, best-corrected visual acuity, and intraocular pressure (IOP) assessments preoperatively and postoperatively. Postoperative complications were also evaluated. Complete success was defined as IOP of 6 to 18 mmHg with ≥20% reduction from baseline, without medication. Qualified success required similar IOP control with medication. Main Outcome Measures: Intraocular pressure change, medication use, treatment success rate, and postoperative complications over 24 months. Results: A total of 61 eyes from 51 patients were included, with 20 eyes (17 patients) diagnosed with primary open-angle glaucoma and 41 eyes (34 patients) with primary angle-closure glaucoma as their primary condition. The mean age was 60.6 ± 10.6 years, with 30 (58.8%) female patients. Prior surgeries included peripheral iridectomy (23 eyes), trabeculectomy (39 eyes), XEN Gel implant (1 eye), Ahmed valve implant (1 eye), and phacoemulsification and intraocular lens implantation (17 eyes). Among these, complete success was achieved in 26 eyes (42.6%) and qualified success in 52 eyes (85.2%). The mean IOP dropped from 26.4 ± 6.2 mmHg preoperatively to 16.3 ± 4.8 mmHg at 24 months (35.8% reduction; Conclusions: Goniotomy proves to be a safe and effective procedure for patients with previous failed glaucoma surgery over the 24-month study period.
