To study the efficacy of selective laser trabeculoplasty (SLT) in pseudophakic eyes after primary and repeat SLT.
Retrospective review of electronic medical records from affiliated practice of patients with open angle glaucoma who underwent primary (SLT I) and repeat (SLT II) 360-degree SLT for intraocular pressure (IOP) reduction between 06/2003 and 11/2007. Twenty three pseudophakic eyes from 18 patients who underwent cataract surgery at least six months prior to SLT I were included. Patients with history of any incisional ocular surgery other than cataract were excluded. The first age-matched 23 phakic eyes selected from the database served as controls. Demographic data, SLT parameters, IOP and number of glaucoma medications were collected at baseline and 1, 4, 8, 12, 18, and 24 months. Success of the procedure was defined as 20% reduction from baseline IOP. Mean, SD, one way ANOVA followed by Tukey's test, and chi-square (Χ2) test were used for analysis.
Age, race, SLT parameters in pseudophakic and phakic group were not statistically different. Pre-treatment IOP did not differ between groups (19.2±2.5 vs. 19.7±3.2 mmHg before SLTI, P>0.05; 19.2±3.4 vs. 18.9±4.6 mmHg before SLT II, p>0.05). Mean numbers of glaucoma medications did not change during 24 month follow-up in both groups. Percentage of pseudophakic and phakic eyes achieving ≥20% IOP reduction did not statistically differ after primary and repeat SLT up to 24 months (Table).
Percentage of successful IOP reduction from primary and repeat SLT in pseudophakic eyes was not significantly different from phakic eyes. These retrospective data suggest primary and repeat SLT were similarly effective in phakic and pseudophakic eyes.
