Abstract

PURPOSE
To evaluate the effect on intraocular pressure(IOP) of cataract surgery in chronic glaucoma patients. METHODS: We reviewed the change of IOP retrospectively in patients with controlled chronic primary glaucoma who did not show change in the number of glaucoma medications pre- and postoperatively after sutureless phacoemulsification and intraocular lens implantation up to 5 years of follow-up periods. This study included 15 patients with chronic open angle glaucoma and 13 patients with chronic angle closure glaucoma. Mean duration of follow-up period was 39.6 months. RESULTS: The mean preoperative IOP was 15.32 mmHg and mean postoperative IOP was 14.82 mmHg at last follow-up. There was statistically significant difference between pre- and postoperative mean IOP until 1 year postoperatively(p<0.05) but not significant thereafter(p>0.05). There was no significant difference in mean IOP during the follow-up period between chronic open angle and chronic angle closure glaucoma. The degree of IOP reduction was statistically significant until 1 year postoperatively but did not thereafter. There was no statistically significant difference in mean IOP reduction between chronic open angle and angle closure glaucoma during the follow-up periods. CONCLUSIONS: These results suggest that intraocular pressure(IOP) after cataract surgery in controlled primary glaucoma patients might be slight reduced up to 1 year postoperatively, but the removal of cataract does not seem to significantly affect IOP level in the long run.
