2、干断层扫描仪分别测量LASIK术后1周每个角膜上0。和90。两条子午线所在截面上特定7个点的角膜瓣厚度。两组角膜瓣预计值均为110m。结果术后1周激光组制作的角膜瓣形态均一、规整,形状近似规则的平面,两条子午线问角膜瓣厚度无明显差异(t=1.582,P=0.114)。角膜刀制作的角膜瓣呈周边厚,中央薄的新月形,两条子午线间角膜瓣厚度无明显差异(t=1.010,P=0.313)。激光组与角膜刀组相比,仅中央点两者厚度无明显差别,其余各点两者间均存在明显差异(P<0.05)。激光组角膜瓣实际厚度与预计值的差值(7.15±4.89)m明显小于角膜刀组(18.97±
3、11.56)txm,差异有统计学意义(P<0.01)。结论飞秒激光组制作的LASIK角膜瓣比微型角膜刀制作的LASIK角膜瓣更精确;重现性更好;形态更均一、更规整。【关键词】准分子激光角膜原位磨镶术;角膜瓣厚度;飞秒激光;傅立叶光学相干断层扫描【中国图书分类号】R772.2ComparisonofthemorphologyofflapscreatedbyIntraLaseFS60femtosecondlaserandMoriaM2mechanicalmicrokeratomeHUYalfin,ZttOUYuehua,andZHANGJing.BeijingT
