Abstract
Aim: To evaluate the effectiveness of brinzolamide–brimonidine fixed combination to control the intraocular pressure elevation throughout the first 24 h following uncomplicated phacoemulsification cataract surgery. Patients and Methods: A total of 62 patients who underwent phacoemulsification cataract surgery were included in this prospective randomized comparative case series. The brinzolamide–brimonidine fixed combination group (34 eyes) was administered a single dose of brinzolamide–brimonidine fixed combination immediately after phacoemulsification. No treatment was administered in the control group (28 eyes). Intraocular pressure was measured 1 day before surgery (baseline) and at 6, 12 and 24 h postoperatively. Results: The brinzolamide–brimonidine fixed combination group had significantly lower intraocular pressure at 6, 12 and 24 h after phacoemulsification compared to baseline (p < 0.0001 for all comparisons), while in control group, intraocular pressure was significantly higher at 6 and 12 h after surgery compared to baseline (p < 0.001 and p < 0.0001, respectively). In control group, an intraocular pressure elevation ⩾ 5 mm Hg was noted in 32.4% of the eyes at 6 and 12 h and in 5.9% of eyes at 24 h after surgery, while in brinzolamide–brimonidine fixed combination group, only 8.8% of the eyes at 6 h postoperatively had such an intraocular pressure elevation. Conclusion: The administration of a single drop of brinzolamide–brimonidine fixed combination effectively prevented intraocular pressure elevations and intraocular pressure spikes during the first 24 h after uneventful phacoemulsification.
