Early Changes in Intraocular Pressure Following Phacoemulsification

To evaluate early postoperative changes in intraocular pressure (IOP) following phacoemulsification and intraocular lens (IOL) implantation. This prospective study included 129 eyes with open angles and normal or high IOP undergoing phacoemulsification and IOL implantation for senile cataracts. The patients were divided into 3 groups (Gs) based on preoperative IOP:? 15 mmHg (G1, n=76); from 16 to 20 mmHg (G2, n=43) and; from 21 to 30 mmHg (G3, n=10). IOP was measured by Goldmann applanation tonometry one day before surgery, and 1 and 6 weeks postoperatively. IOP was decreased postoperatively in all study groups 1 and 6 weeks after surgery as follows: 2.8±1.5 and 1.8±1.7 mmHg respectively in G1 (P
