Prophylactic Effect of Oral Acetazolamide against Intraocular Pressure Elevation after Cataract Surgery in Eyes with Glaucoma

Eyes with POAG experienced short-term IOP elevation from 3 to 7 hours after phacoemulsification. Oral acetazolamide administration 1 hour preoperatively significantly reduced the IOP elevation from 1 to 24 hours, while administration 3 hours postoperatively reduced the IOP elevation at 5 hours or more after surgery.
