Abstract

Study Design: Retrospective
Purpose:To examine effects of phaco on long term intraocular pressure(IOP)in patients with medically treated primary open-angle glaucoma(POAG),pseudoexfoliation glaucoma(PXG),or primary angle closure glaucoma (PACG)without prior or concurrent glaucoma surgery
Methods:A minimum follow up of 1 year was followed.Patients were evaluated before surgery and at 7 days,1 month,3 months, 6 months and 1 year after surgery for IOP and the number of medications
Results:154 eyes of 85 patients were included.Patients were using a mean of 1.5-1.9 medications before surgery.One year post surgery,change of IOP was a mean -1.15±3 mmHg(p=0.01),-2.14±3mmHg(p=0.005) and -4.2±3 mmHg(p<0.001) in the three groups respectively and a change in the number of medications by a mean of -0.1±0.43 ,-0.5 ± 0.48 and -1.1±0.52 respectively
Conclusion: Phacoemulsification results in small, moderate, and marked reductions of IOP and medications for patients with POAG, PXG, and PACG respectively
