영문 초록

Purpose: To compare the corneal measurements of orbscan and pentacam in normal subjects. Methods: From April 10 th 2006 to May 10 th 2006, subjects were tested by automated refractokeratometry (Canon RK-1, Japan), Pentacam (OCULUS, Germany), and Orbscan (Orbtek Inc, USA). Measurements included central, superior, nasal, inferior and temporal corneal thickness, radius of anterior elevation and posterior elevation, keratometric value and axis of the 4 mm zone, and anterior chamber depth. Results: A total of 96 eyes from 48 patients were included, with 13 men and 35 women. Average age was 25.4 years old. In comparing the Orbscan and Pentacam, central, superior and temporal corneal thicknesses of the Pentacam were significantly thicker than those of the Orbscan (paired t-test, p=.000, p=.000, p=.003). The mean K value of the 4mm zone of the Orbscan was steeper than that of the Pentacam (paired t-test, p=.000). The anterior chamber depth of the Pentacam was deeper than that of the Orbscan (paired t-test, p=.000), but all of the Pentacam measurements were strongly correlated to those of the Orbscan. Conclusions: The measurements of the Pentacam and the Orbscan were significantly different, but they were strongly correlated. Both machines can be useful in clinical applications with partial compensation.
