Abstract

Purpose:: The purpose of this study was to compare central corneal thickness (CCT), best fit anterior and posterior sphere measurements obtained with the Pentacam (Oculus) with scanning slit topography (Orbscan; Bausch & Lomb), and with ultrasound pachymetry (Nidek).

Methods:: CCT in 50 consecutive healthy, un-operated practice patients (100 eyes) was measured twice with each modality.

Results:: The mean CCT values as determined with the different modalities (+/-standard deviation) were: 532+/-29 microm, 555+/-37 microm, 530+/-34 microm, respectively. The differences between modalities (+/-95% limits of agreement) were -2.8+/-21 microm between rotating Scheimpflug and ultrasound, 25+/-31.2 microm between scanning slit and ultrasound, and 23+/-27 microm between scanning slit and rotating Scheimpflug imaging.

Conclusions:: In the assessment of normal corneas, the Pentacam measured CCT values closer to ultrasound pachymetry and with less variability compared with Orbscan.
