Abstract

Purpose:

To determine the effectiveness and safety of combined MicroPulse transscleral laser therapy (TLT) and phacoemulsification in patients with co-existing cataracts and glaucoma.

Methods:

A retrospective consecutive case series of 22 eyes of 19 patients with co-existing cataract and glaucoma. The patients underwent MicroPulse TLT, phacoemulsification, and intraocular lens implantation during the same setting. A comparison of baseline data with the data at 18 months follow-up was made to determine the variation in best-corrected visual acuity (BCVA), intraocular pressure (IOP), and changes in the number of anti-glaucoma drugs.

Results:

Twenty-two eyes of 19 patients (57.9% were female) underwent combined MicroPulse TLT and phacoemulsification. The mean age was 60.5±9.3 years (range: 39.0 to 76.0). Nine eyes (40.9%) had primary open-angle glaucoma, nine eyes (40.9%) had chronic angle-closure glaucoma, and four eyes (18.2%) had pseudoexfoliation glaucoma. The mean baseline IOP was 26.3±4.7, which was significantly reduced to 15.3±2.4 mmHg (43.9%±10.2%) at 18 months (p<0.001). The median number of glaucoma medications was 4 (2 to 5) at baseline and 2 (0 to 4) at 18 months (p=0.002). The mean BCVA was 0.84±0.31 LogMAR (Snellen: 20/138) at baseline and 0.28±0.23 LogMAR (Snellen:20/38) at 18 months (p<0.001). The mean follow-up period was 15.8±3.0 months (range 12 to 18).

Conclusions:

Combined MicroPulse TLT and phacoemulsification was a safe and effective procedure that achieved reduction in both IOP and glaucoma medications for up to 18 months, with no associated vision-threatening complications.
