Purpose:To report 3-year results evaluating the effect on safety and efficacy of canaloplasty to treat open-angle glaucoma when combined with cataract surgery.Patients and Methods:This was a retrospective subset analysis of a prospective, international, multicenter study evaluating 133 eyes of 133 adult, open-angle glaucoma patients who underwent canaloplasty with tensioning suture placement. Eighty-two phakic eyes that received canaloplasty alone were compared with 51 eyes that underwent cataract surgery before or during canaloplasty.Results:Phakic eyes that received combined cataract-canaloplasty surgery (phacocanaloplasty) had a meanSD baseline IOP of 23.5 +/- 5.2 mm Hg and mean glaucoma medication usage of 1.5 +/- 1.0 decreasing to a mean IOP of 13.6 +/- 3.6 mm Hg on 0.3 +/- 0.5 medications at 3 years postoperatively. Pseudophakic eyes undergoing canaloplasty had a mean baseline IOP of 23.9 +/- 5.2 mm Hg on a mean of 1.8 +/- 0.8 glaucoma medications decreasing to 15.6 +/- 3.5 mm Hg on 1.1 +/- 0.8 medications at 3 years. In phakic eyes, reductions in IOP were significantly greater and less postoperative IOP lowering medication was needed after undergoing phacocanaloplasty compared to eyes which had canaloplasty alone.Conclusions:Clear corneal phacoemulsification performed before or in combination with canaloplasty is a safe and effective surgical procedure to reduce IOP in adult patients with open-angle glaucoma.
