To analyze the actual corneal flap thickness (FT) after flap making by MK-2000 microkeratome during laser in situ keratomileusis (LASIK), 42 females and 20 males with myopia or myopic astigmatism were enrolled in this study. FTs were created using a microkeratome with a 130 microm head. Corneal thickness was measured by ultrasonic pachymeter. The correlations between FT and central corneal thickness (CCT), keratometric power and age were analyzed. The mean age at operation for all study subjects was 27.6+/-4.9 years. The average FT was 133.2+/-15.4 microm. The average CCT was 540.+/-30.3 microm. The average keratometric power was 43.66+/-1.32 D. There was a positive correlation between FT and CCT and no correlation between FT and keratometric power or between FT and age. We recommend that LASIK surgeons inspect the actual FT when using microkeratome.
为分析在准分子原位角膜磨镶术（LASIK）中使用MK - 2000微型角膜刀制作角膜瓣后的实际角膜瓣厚度（FT），本研究纳入了42名女性和20名患有近视或近视散光的男性。使用头部为130微米的微型角膜刀制作角膜瓣厚度。通过超声角膜测厚仪测量角膜厚度。分析了角膜瓣厚度与中央角膜厚度（CCT）、角膜曲率以及年龄之间的相关性。所有研究对象的平均手术年龄为27.6±4.9岁。平均角膜瓣厚度为133.2±15.4微米。平均中央角膜厚度为540.±30.3微米。平均角膜曲率为43.66±1.32 D。角膜瓣厚度与中央角膜厚度之间呈正相关，而角膜瓣厚度与角膜曲率或角膜瓣厚度与年龄之间无相关性。我们建议LASIK手术医生在使用微型角膜刀时检查实际的角膜瓣厚度。
