ABSTRACT
To evaluate the differences and factors to be considered when measuring intraocular pressure after photorefractive keratectomy[PRK]and laser in situ keratomileusis[LASIK], we prospectively reviewed the medical records of myopic eyes between -4~-7 diopters. Among them, 14 patients, 22 eyes underwent PRK and 10 patients, 18 eyes recieived LASIK. We measured intraocular pressures by Goldmann applanation tonometry preoperatively, 1 month, 3 months and 6 months postoperatively in each group. Corneal curvatures, central corneal thicknesses were measured and compared when measuring intraocular pressure. The postoperative intraocular pressure was lower than the preoperative value in both groups[p<0.01], and the decreased amount of IOP were not statistically different in both groups[p=0.29]. Targeted ablation depth[p=0.19]and ablation diameter[p=0.16]did not show statistically significant correlation to postoperative IOP decrease. In measuring intraocular pressure after PRK or LASIK, attention should be given to the pressure and its interpretation.
