Reliability and repeatability of the Pentacam on corneal curvatures [PDF]

Australasian journal of optometry, The, 2009
The purpose of this study was to assess the intra-observer reliability and inter-session repeatability of the Pentacam system (Oculus, Inc.) on the simulated keratometry readings (Sim K) and peripheral corneal curvatures (PCC) at both the anterior and posterior corneal surfaces.One eye was randomly selected from each of the 39 normal subjects from the ...
