Intrascleral intraocular lens fixation with ab interno trabeculotomy in patients with exfoliation glaucoma with lens subluxation

Purpose To evaluate the surgical outcomes of intrascleral intraocular lens (IOL) fixation using ab interno trabeculotomy (LOT) in patients with exfoliation glaucoma with lens subluxation. Study design Retrospective case series. Methods Twenty eyes of 18 patients with exfoliation glaucoma and lens or IOL subluxations were included. Three success criteria were based on postoperative intraocular pressure (IOP) (A, ≤15 mmHg; B, ≤18 mmHg; C, ≤21 mmHg). The IOP, number of glaucoma medications, and visual acuity were compared before and after surgery. Success probability was analyzed using Kaplan–Meier survival curves. Cox proportional hazards’ regression models were used to examine prognostic factors for surgical failure. Results The mean follow-up period was 23.4 ± 7.8 months. The mean IOP significantly decreased from 23.2 ± 6.8 mmHg preoperatively to 14.0 ± 4.4 mmHg at 1 year postoperative ( P
