EVALUATION OF CHANGES IN IOP FOLLOWING PHACOEMULSIFICATION WITH PCIOL IMPLANTATION AND ITS CORRELATION WITH OCULAR BIOMETRIC PARAMETERS

Abstract

Background: The intraocular pressure is reduced by phacoemulsification with PCIOL in accordance to the intraocular pressure observed prior to surgery. The postoperative decrease in intraoperative pressure is linked to a number of preoperative conditions.

Aim: The purpose of this study was to evaluate the effects of phacoemulsification with PCIOL implantation on intraocular pressure after cataract surgery. It also aimed to evaluate the correlation between preoperative ocular parameters, such as AL ACD, AL, and CCT, and changes in intraocular pressure after surgery.

Methods: 262 patients with cataracts, of both sexes, had phacoemulsification and PCIOL implantation as surgical treatments. After surgery, ocular biometric parameters and IOP reduction were assessed in all individuals on the first postoperative day and one month later.

Results: BCVA using a LogMAR chart was 1-0.76 for study individuals prior to surgery and 0.16-0 thereafter. Preoperative BCVA using the Snellen chart was 72%, while postoperative BCVA was 67%. Preoperatively, the ACD was 3.25±0.26, but it raised to 3.64±0.29 (p<0.001) considerably. Following surgery, the mean intraocular pressure (IOP) of the operated eyes dropped dramatically (p<0.001) to 11.50±1.68 mm Hg. Preoperative mean IOP was observed to be 13.46±1.96 mmHg, and it dropped to 11.56±1.64 mmHg postoperatively. After a month, there was a 1.92±0.59 mmHg change in the mean IOP. 14.11% was the percentage change in IOP at one month. It was statistically significant (p<0.001) that the mean intraocular pressure changed.

Conclusion: The current study suggests that normal eyes with cataracts, especially those related with age, have a considerable reduction in intraocular pressure following phacoemulsification with PCIOL implantation. Furthermore, in patients with cataracts, ACD is substantially linked to the postoperative drop in intraocular pressure as compared to preoperative intraocular pressure.
