The Outcome of Manual Small Incision Cataract Surgery (MSICS) Using Ruit’s Technique in Phacomorphic and Phacolytic Glaucoma at Nan Hospital, Thailand

Abstract

Objective: To evaluate the visual outcome and complications of manual small incision cataract surgery (MSICS) using Ruit’s technique in the treatment of patients with phacomorphic and phacolytic glaucoma. Materials and Methods: The medical records of 150 eyes in 147 patients with phacomorphic and phacolytic glaucoma who underwent MSICS by the Ruit’s technique between January 2009 and May 2022 at Nan Hospital, were retrospectively reviewed. Out of these 150 eyes from the 147 patients, 58 eyes from 58 patients missed the six-week follow-up, and 14 eyes from 14 patients had pre-operative vision impairing pathology. Records were analyzed of the patients with pre-operative, post-operative uncorrected visual acuity (UCVA), intraocular pressure (IOP), operative time, intraoperative difficulties and complications, and post-operative complications and astigmatism in the second and sixth week after surgery for the 78 eyes out of 75 patients. Results: Seventy-eight eyes of 75 patients treated by MSICS using Ruit’s technique with IOL implanted in the posterior chamber demonstrated no significant intraoperative or post-operative complications. The post-operative UCVA at the sixth-week follow-up was 20/70 or better in 76% of the phacomorphic glaucoma group and 64% of the phacolytic glaucoma group. In the sixth week after treatment, the mean post-operative astigmatism of the phacomorphic glaucoma group was –1.4±0.9 D and –1.3±0.7 D for the phacolytic glaucoma group. The mean post-operative IOP in the sixth week after surgery for phacomorphic glaucoma and phacolytic glaucoma were 10.7±3.7 mmHg and 9.8±4.3 mmHg, respectively. Conclusion: Manual small incision cataract surgery (MSICS) using Ruit’s technique is an effective method and excellent at controlling the IOP and achieving good visual acuity with a low rate of complications for patients with phacomorphic and phacolytic glaucoma.
