- 4 ∼ - 7 diopter 사이의 근시 환자에서 레이저 각막 절제술과 각막 절삭가공 성형술후 Goldmann 압평안압계로 측정된 안압의 차이 및 이에 끼치는 영향요소

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(J Korean Ophthalmol Soc 41:613~619,2000).
