Abstract: :
Purpose:To evaluate and compare the effect of clear corneal cataract extraction with foldable intraocular lens implantation on intraocular pressure (IOP) in patients with medically controlled primary open angle glaucoma, ocular hypertension, and normal patients. Methods:35 patient records from the Kresge Eye Institute were reviewed. All patients underwent uncomplicated clear corneal cataract extraction with foldable intraocular lens implantation. Patients were divided into two groups. Group 1 consisted of 15 patients with primary open angle glaucoma or ocular hypertension controlled on medical therapy and group 2 consisted of 20 patients without glaucoma. Demographic data, IOP and number of glaucoma medications were recorded preoperatively and at intervals over six months post-operatively. Results:There were no differences between the groups with respect to demographic data. There was no significant change in mean intraocular pressure following cataract extraction in group 1 or 2 at 1 day, 1, 3, or 6 months. The number of medications needed for IOP control in group 1 one did not change at 6 months compared to preoperative. However, IOP spikes were more prevalent in group 1 compared to group 2 (P=0.03). Conclusion:Following uncomplicated clear corneal cataract surgery there was no significant change in mean IOP at 6 months compared to preoperative in normal, ocular hypertensive patients, or patients with medically controlled primary open-angle glaucoma. IOP spikes at post-operative day 1 were more common in patients with ocular hypertension and glaucoma compared to normotensive patients.
