摘要 目的观察近视患者在波前像差引导个体化LASEK手术前后角膜厚度的变化,对有关因素进行分析。方法用DGH 4000型角膜测厚仪测量,在施行LASEK手术前后分别测量角膜中央厚度差异,用电脑验光仪检测术前及术后角膜曲率和屈光度。结果近视患者158例(316眼),术后平均角膜中央厚度为(517.38±34.19)μm,左右眼、性别、年龄间平均角膜中央厚度差异均无统计学意义;与术前比较,术后平均眼压下降(3.90±0.55)mmHg,角膜中央厚度下降(97.92±7.22)μm,屈光度下降(-8.22±3.24),差异均有统计学意义;角膜曲率虽有下降,但无统计学意义。角膜中央厚度与屈光度和眼内压呈正相关,与角膜曲率无相关性。结论术后近视患者角膜中央厚度变化与屈光度、眼内压等因素有相关性。
