Comparison of central corneal thickness measurements after LASEK by three instruments
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). <p>METHODS:Forty-nine patients(96 eyes)with myopia a...

| description | 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). <p>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 <i>t</i>-test and Pearson correlation analysis was used for statistical analysis. <p>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(<i>P</i><0.05). Ultrasound pachymetry had a positive correlation with OCT and Tomey pachymetry(<i>P</i><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.<p>CONCLUSION: The CCT measurements of three instruments were not interchangeable. |
