PURPOSE: To examine the changes in intraocular pressure (IOP) and the incidence of substantial rises in IOP in the early period after cataract surgery in eyes with open-angle glaucoma (OAG). SETTING: Hayashi Eye Hospital, Fukuoka, Japan. METHODS: The study included 32 eyes of 32 patients with OAG and 31 control eyes of 31 age-matched patients scheduled for phacoemulsification surgery. The IOP was measured preoperatively and 1, 2, 3, 5, 7, 14, and 28 days postoperatively. The incidence of a substantial rise in IOP postoperatively was evaluated, with the criterion being an IOP higher than 30 mmHg. RESULTS: In the OAG group, the mean IOP increased 1, 2, and 3 days postsurgery and then decreased, whereas in the control group, it decreased from day 1 postsurgery. Although no significant differences were found between groups preoperatively, the mean IOP in the OAG group was significantly higher than in the control group postoperatively. Furthermore, the mean IOP decrease was also less in the OAG group than in the control group. A substantial increase in IOP occurred at day 1 postsurgery in 4 eyes (12.5%) in the OAG group, whereas no eyes in the control group showed such an increase; this difference was significant (P =.0419). CONCLUSIONS: A substantial increase in IOP occurred in an approximately 13% of eyes with OAG 1 day after phacoemulsification surgery. The IOP shortly after surgery was significantly greater in the eyes with OAG than in nonglaucomatous eyes.
