  2. OBJECTIVE To compare de central corneal thickness measurements found using non contact methods as are Visante OCT, Pentacam and Galilei.

  3. MATERIALS AND METHODS • Prospective, comparative, and double blinded study measuring central corneal thickness on 50 eyes of 25 patients being evaluated for refractive surgery. The measurements were taken by three different researchers without knowing the previous results obtained by the other devices. • We analyzed the thickness averages, maximum and minimum values, and their standard deviations. The statistical analysis was made using ANOVA testing and SPSS v 15.

  4. RESULTS Our subjects mean age was 30.8 (SD=5.736). The central thickness average for Visante OCT was 530.02 ± 30.682, for Pentacam was 554.76 ± 32.028, and for Galilei was 562.38 ± 29.21. When comparing the three devices we found that there’s a statistical difference between the measurements (p=0.000), and when comparing PentacamvsGalilei that difference is not found (p=0.648).

  6. RESULTS Mean of corneal thicknessmeasurement value was not statistically significant comparing the three devices.

  7. CONCLUSION Our subjects mean age was 30.8 (SD=5.736). The central thickness average for Visante OCT was 530.02 ± 30.682, for Pentacam was 554.76 ± 32.028, and for Galilei was 562.38 ± 29.21. When comparing the three devices we found that there’s a statistical difference between the measurements (p=0.000), and when comparing PentacamvsGalilei that difference is not found (p=0.648).
