目的:比较光学相干断层扫描( optical coherence tomography ,OCT)、角膜内皮计与超声测厚仪测量准分子激光上皮下角膜磨镶术( laser subepithelial keratomileusis , LASEK)术后患者中央角膜厚度( CCT )的差异性和相关性。<br> 方法:选取LASEK术后6 mo复诊的近视患者49例96眼,对每位患者分别用OCT、角膜内皮计、超声测厚仪三种仪器测量其CCT,数据统计分析采用配对t 检验和Pearson相关性分析。<br> 结果:OCT、角膜内皮计、超声测厚仪测量CCT的平均值为分别为475.15±33.67,447.80±34.11,465.18±34.23μm。手术预留CCT平均值为431.22±35.32μm。三种仪器所测量结果之间两两比较差异均有统计学意义(P<0.05)。线性相关显示超声测厚仪与OCT、角膜内皮计两种仪器之间存在正相关( r=0.949,0.983, P<0.01)。 LASEK术后实际CCT较手术预留角膜厚度要厚。<br> 结论:三种仪器的中央角膜厚度测量值不可互换。

AIM: To compare the differences and the relationships of central corneal thickness ( CCT) measurements among optical coherence tomography ( OCT ) , Tomey pachymetry and ultrasound pachymetry after laser assisted subepithelial keratomileusis ( LASEK) . <br> METHODS:Forty-nine patients ( 96 eyes ) with myopia after 6mo of LASEK were assigned to measure the CCT by OCT, Tomey pachymetry and ultrasound pachymetry. Paired t-test and Pearson correlation analysis was used for statistical analysis. <br> RESULTS: The mean CCT measured by OCT, Tomey pachymetry and ultrasound pachymetry was ( 475.15 ± 33.67μm), (447.80 ±34.11μm), (465.18 ±34.23μm), respectively.Surgery reserved mean CCT was ( 431.22 ± 35.32 )μm.There were statistically differences between two comparative measured results (P<0.05).Ultrasound pachymetry had a positive correlation with OCT and Tomey pachymetry ( P <0.01 ), and the correlation coefficient was 0.949 and 0.983, respectively.The actual CCT of 6mo post-operation was thicker than surgery reserved CCT. <br> CONCLUSION: The CCT measurements of three instruments were not interchangeable.
