Phacoemulsification with excimer laser trabeculotomy reduced IOP and the need for IOP-reducing medications in patients with glaucoma or ocular hypertension, according to a study.

“IOP remained significantly reduced from baseline 12 months after phaco-ELT [excimer laser trabeculotomy] regardless of preoperative IOP levels, with no major complications. The IOP reduction remained constant over the entire follow-up,” the study authors said.

Investigators prospectively evaluated 64 eyes of 64 patients who underwent phacoemulsification with excimer laser trabeculotomy. Mean patient age was 76.5 years.

The study group comprised 40 eyes with preoperative IOP of 21 mm Hg or less; a control group included 24 eyes with IOP of 21 mm Hg or greater.

Study results showed mean IOP in the study group was reduced by 1.9 mm Hg and medication use decreased by 1.1. Both reductions were statistically significant (P = .012 and P < .001, respectively).

Mean IOP in the control group decreased by 9.5 mm Hg and medication use decreased by 0.7; the decreases were statistically significant (P < .001 and P = .085, respectively).

Best corrected visual acuity improved significantly in all eyes (P < .001).
