• One hundred nineteen eyes of 99 patients were prospectively followed up for 12 to 21 (mean, 17) months. Laser powers used were lower than those originally proposed by other physicians and ranged from 500 to 800 mW. The postoperative pressure reduction was statistically significant in each power group. The pressure reduction was statistically significantly dependent on the grade of pigmentation on the trabecular meshwork. The quality of the visible burn effect or placement of burns did not have any impact on the postoperative pressure reduction.
