SUBJECT: To evaluate the effect of number of pulses, energy per pulse and total energy on intraocular pressure (IOP) in patients with posterior capsule opasification who were treated with YAG laser posterior capsulotomy. MATERIAL AND METHODS: Thirty pseudophacic patients with posterior capsule opacification were treated with Nd: YAG laser capsulotomy. All the patients included in the study were treated with prophilactic %1 apraclonidine, administered one hour before the procedure. IOP was measured with Goldmann applanation tonometry one hr before and 30 min, 1 hr, 2 hr, 4 hr, 24 hr and 1 week after the process. RESULTS: There was a positive relation between the number of pulses and rise in IOP at 30 min, one hr, 2 hr, 4 hr and 24 hr after the procedure but no significant relation was found in one week results. A positive and significant relation betwen pulse energy and rise in IOP was found at 30 min, one hr, 2 hr and 4 hr after the procedure. There was no significant relation in 24 hr and one week values after the procedure. In addition there was a positive relation between total energy and the rise in IOP at 30 min, one hr, 2 hr, 4 hr and 24 hr after the process. The rise in IOP one week after the process was not significant. CONCLUSION: This study indicates that pulse number, pulse energy and total energy which was applied during the operation increases the risk of a sudden rise in IOP. Therefore, in addition to using preoperative antiglaucomatous prophilaxy, during the operation minimum pulse energy and pulse number should be used. LA: Turkish
