목 적: 각막굴절교정수술을 받은 환자를 대상으로 비접촉식 안압계로 안압을 측정하고 측정안압에 영향을 주는 변수를 분석하고자 하였다. 방 법: LASIK 또는 LASEK 각막굴절교정수술을 받은 154명(261안)을 대상으로 하였다. 안압은 비접촉식 안압계(KT-800, KOWA, JAPAN)를 이용하여 측정하였고, 각막곡률, 각막지형도검사, 중심각막두께는 Orbscan(OrbscanⅡ, Bausch+Lomb, USA)을 이용하여 측정하였다. 수술 후 안압 변화량과 중심각막두께 변화량, 각막곡률 변화량 및 교정굴절력과의 상관성은 SPSS ver. 18.0(SPSS Inc, Chicago, Illinois)를 이용하여 분석하였으며 유의수준은 p
Purpose: To investigate the significant parameters that affect intraocular pressure (IOP) measured by non-contact tonometry in patients who have undergone corneal refractive surgery. Methods: One hundred fifty four subjects (261 eyes) who underwent Laser in Situ Keratomileusis LASIK) or Laser assisted sub-epithelial keratomileusis (LASEK) were participated. IOPs were measured with non-contact tonometer (KT-800, KOWA, JAPAN) and corneal curvature, corneal ablation amount and central corneal thickness measurement were performed by using Orbscan topography (Orbscan Ⅱ, Busch + Lomb, USA). The correlation between the changes of IOP and the changes of central corneal thickness, corneal curvature drop and corrected diopter value were investigated statistically using SPSS 18.0 (SPSS Inc, Chicago, Illinois). Differences were considered significant when the P vale was less than 0.05. Results: The subjects who received corneal refractive surgery were in the mean age of 31.45±5.98 years and 83 patients (131 eyes) were in LASIK group and 71 patients (130 eyes) were in LASEK group. The Pre and post operative IOPs showed positive correlation with the central corneal thickness (R=0.25, p
