Real-World Outcomes of Canaloplasty and Trabeculotomy Combined with Cataract Surgery in Eyes with All Stages of Open-Angle Glaucoma.

Purpose To evaluate the long-term safety and efficacy of sequential canaloplasty and trabeculotomy combined with cataract surgery in patients with mild, moderate, and advanced open-angle glaucoma. Patients and Methods Case records of 171 consecutive patients (171 eyes) who had undergone cataract surgery followed by canaloplasty (≥180°) and trabeculotomy (≥90°) for mild, moderate, or advanced open-angle glaucoma (Shaffer grade ≥3) using the OMNI Surgical System (Sight Sciences, Inc., Menlo Park, CA) were analyzed retrospectively. Efficacy endpoints included change in mean IOP and number of medications from baseline to postoperative 12- and 24-months for the overall dataset and stratified by each stage of glaucoma. Kaplan–Meier survival analysis of success (eyes that did not require secondary surgical interventions (SSI)) by postoperative 24 months was also performed. Results Postoperatively, there was a statistically significant reduction in IOP (baseline of 17.2 mmHg on 1.3 medicines reduced to 14.3 on 0.8 medicines (12 months) and 14.0 on 0.9 medicines (24 months), p<0.001 for both time points). Eyes with advanced glaucoma (N=63) maintained significant IOP reduction (17.8 mmHg on 1.6 medicines at baseline reduced to 13.6 mmHg on 1.3 medicines (12 months) and 13.0 on 1.5 medicines (24 months), p<0.001). Kaplan–Meier analysis showed a 93.0% survival probability for the avoidance of SSI at 2 years after surgery. Conclusion Canaloplasty and trabeculotomy combined with cataract surgery provided effective IOP reduction for eyes with all stages of glaucoma at postoperative 12 and 24 months, and the procedure yielded a 93% survival rate for SSI avoidance at 2 years.
