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


PMID 23429620

Abstract

To report 3-year results evaluating the effect on safety and efficacy of canaloplasty to treat open-angle glaucoma when combined with cataract surgery. 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. 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. 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.
