Phacoemulsification and intraocular lens implantation before, during, or after canaloplasty in eyes with open-angle glaucoma: 3-year results.

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 mean ± SD 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.
