Purpose:
|
To determine intraocular pressure (IOP) changes and factors influence it after myopic photorefractive keratectomy (PRK)
|
|
Methods:
|
patients underwent myopic PRK followed at 1, 2, and 3 month postoperatively. Intraocular changes and the relation between preoperative IOP, central corneal thickness (CCT), and manifest refraction with postoperative IOP at month 3 were analyzed.
|
|
Results:
|
Sixty-two patients enrolled in the study. Patients’ mean spherical equivalent (SE) was -3.49 D ± 1.49 (Diopter, rang -7.25 to -0.75) at baseline, which reduced to -0.04 D ± 0.24 (-0.75 to 0.63) post PRK (p< 0.01). The mean IOP was 13.6±2.1 mmHg and the mean central corneal thickness was 542 ± 30 µm (482 to 610 µm)preoperatively. At the first two months postoperatively, no significant change was seen, but at month 3, IOP decreased to 12.7±2.5 (change: -1±2.2, p<0.05). The decrease in IOP at month 3 was linearly related to preoperative IOP and not related to preoperative SE or CCT.

|
Conclusion:
|
Intraocular pressure was measured lower three months after myopic PRK and eyes with higher preoperative IOP experienced a greater IOP decrease
