Purpose The purpose of this study was to investigate the safety and efficacy of phacocanaloplasty with suprachoroidal drainage (PCscD) and to compare its intraocular pressure ( IOP )‐lowering and drug‐sparing effect to canaloplasty with suprachoroidal drainage (CscD). Methods The study retrospective interventional study included patients with open‐angle glaucoma or secondary forms of glaucoma who underwent either CscD or PCscD between the year 2011 and 2014 in Knappschaft Eye Clinic Sulzbach. Primary end‐points were IOP reduction and the number of IOP ‐lowering medication after 12 months. Secondary end‐points were intraoperative and postoperative complications. Results A total of 328 eyes were included, 193 were treated with CscD and 135 underwent PCscD. Canaloplasty with scD achieved an IOP reduction of 37.0% (from 20.9 ± 3.6 mmHg to 13.2 ± 2.6 mmHg) after 1 year, whereas PCscD showed a significant higher reduction of 47.4% (from 23.2 ± 5.1 mmHg to 12.2 ± 1.7 mmHg). Reduction in IOP ‐lowering medication was higher after PCscD (from 3.6 ± 0.6 to 0.2 ± 0.5) than after CscD (from 3.5 ± 0.8 to 0.7 ± 1.0). Twelve months after surgery 55.5% in the CscD group and 80.2% in the PCscD group were free of IOP ‐lowering medication. In both groups, no severe or sight‐threatening complications occurred. Conclusion Combining cataract surgery and CscD achieves a higher IOP reduction, and patients postoperatively need less IOP ‐lowering medication than after CscD alone.
