PURPOSE: To review changes in intraocular pressure (IOP) after cataract surgery on glaucomatous eyes. CASES AND METHOD: This study involved 132 eyes that underwent phacoemulsification and aspiration during the past 7 years 3 months. The series comprised 92 eyes of primary open-angle glaucoma (POAG) and 40 eyes of exfoliation syndrome. All the eyes had IOP below 21 mmHg before surgery with topical medications. IOP averaged 15.6 ± 3.0 mmHg in POAG group and 14.9 ± 2.7 mmHg in exfoliation syndrome. Cases were followed up for 3 months and longer, average 29 months. Findings: Final IOP after surgery averaged 16.0 + 5.1 mmHg in POAG group. The difference was not significant (p = 0.44). It averaged 13.1 ± 3.1 mmHg in exfoliation syndrome. The difference was significant (p = 0.0013). There were 10 eyes with poor IOP control after surgery. They had significantly higher IOP before surgery and had a higher incidence of ruptured posterior capsule. CONCLUSION: Cataract surgery induces reduction in IOP in exfoliation syndrome. There are two risk factors for rise in IOP after surgery: high IOP before surgery and rupture of posterior capsule. LA: Japanese
