Use of the YAG laser with a seven-micron spot in pseudophakic eyes.

Abstract We report on 216 cases of posterior capsulotomy performed with a LASAG Microruptor II YAG laser in patients with posterior chamber intraocular lenses. In 108 cases, the YAG laser was used in multimode with a 70-micron spot and 3.5 mJ to 5.0 mJ of energy; in the other 108 cases, the laser was used in fundamental mode with a 7-micron spot and 0.7 mJ to 1.2 mJ of energy. In the first group, IOL damage was seen in 10.2% of cases, uveitis developed in 0.4% of patients, and transient eye pressure elevation was noted in 6.5% of patients.In the second group, neither IOL damage nor uveitis occurred, and only two cases (1.8%) developed transient pressure elevation.
