%X purpose: to assess the repeatability of central corneal thickness measurement at the geometrical center (central corneal thickness - cct) given by the pentacam high resolution (hr) comprehensive eye scanner (oculus, wetzlar, germany) over time. methods: prospective, single center, observational study. two separate cct measurements were taken by the pentacam corneal tomography exam (ctm) 3 to 12 months apart, and compared. results: one hundred and sixteen eyes (n=116) of 62 health patients were included in this study. average cct in first and last visits was 541.6¡À37 ¦Ìm and 543.6¡À36.9 ¦Ìm respectively. mean difference between both measurements was 9.2¡À6.4 ¦Ìm, and there was no statistically significant difference in cct measurement between visits, with good correlation between them (p = 0.057, r2 = 0,9209). conclusion: pentacam (hr) ctm gives repeatable cct measurements over time.
