INTRODUCTION: This retrospective chart review aims to report a combined surgical approach of intraocular lens (IOL) fixation and gonioscopy-assisted transluminal trabeculotomy (GATT) for the treatment of subluxated IOLs and glaucoma or ocular hypertension.
METHODS: Charts of patients who underwent IOL fixation combined with GATT between November 2019 and July 2023 were reviewed. The main outcome measure was surgical success, defined as a well-centered IOL and an IOP of 18 mmHg or lower and either a 30% IOP reduction or a reduction in medications as compared to baseline. Complications and the need for reoperation were recorded.
RESULTS: Eleven patients who underwent GATT with IOL fixation were included. The mean age was 80.45 years (range: 73-90). IOL subluxation was associated with pseudoexfoliation in all cases. Seven patients underwent scleral fixation, and four underwent iris fixation. The mean follow-up was 15.36 (range: 2.7-26.6) months. The success rate was 72.73%. The mean baseline IOP was 20.63 ± 6.56 mmHg on 2.81 ± 1.53 medications. Four patients were on oral carbonic-anhydrase inhibitor (CAI) before surgery. The mean IOP at the end of the follow-up was 13.86 ± 3.5 mmHg on 1.36 ± 1.57 medications, and none were on oral CAIs. No intraoperative complications occurred, and transient hyphema and vitreous hemorrhage were the most common postoperative complications. All patients had a well-centered IOL. No patients needed additional surgery for IOL position or IOP control. The mean corrected distance visual acuity was 0.634 ± 0.62 logMAR at baseline and 0.36 ± 0.38 at the end of follow-up.
CONCLUSIONS: GATT can be combined with IOL fixation to the sclera or iris to effectively reduce IOP and medication usage.
