PURPOSE: To compare the efficacy of brinzolamide 1% with that of apraclonidine 0.5% in preventing intraocular pressure (IOP) rise after neodymium: YAG (Nd: YAG) laser posterior capsulotomy. SETTING: Department of Ophthalmology, Akdeniz University, Antalya, Turkey. METHODS: One hundred fifteen patients who had Nd: YAG laser posterior capsulotomy for posterior capsule opacification were prospectively randomized to receive brinzolamide 1% (57 patients) or apraclonidine 0.5% (58 patients) approximately 1 hour before laser surgery. A masked observer measured IOP by Goldmann applanation tonometry before treatment and after treatment at 1, 2, and 3 hours and 7 days. RESULTS: The mean IOP changes from baseline were not statistically different between the study groups at 1, 2, and 3 hours and 7 days (P = .109, P = .764, P = .275, and P = .879, respectively). The incidence of IOP elevation of 5 mmHg or higher was 12.2% (7 of 57 eyes) in the brinzolamide group and 10.3% (6 of 58 eyes) in the apraclonidine group (P = .743); IOP elevations of 10 mmHg and greater occurred in 3.5% (2 of 57 eyes) and 1.7% (1 of 58 eyes) (P = .618), respectively. There were no IOP elevations greater than 20 mmHg in either group. CONCLUSION: Brinzolamide 1% and apraclonidine 0.5% given prophylactically before Nd: YAG laser capsulotomy were effective in preventing IOP spikes after treatment.
