To compare measurements of anterior chamber depth (ACD) and corneal curvature obtained with the Pentacam to other commonly used devices.

Prospective, nonrandomized clinical trial.

Measurements of ACD and keratometry were prospectively obtained in 22 eyes of 11 subjects with the Pentacam compared with measurements of the ultrasound (US) A-scan and IOLMaster (ACD), and with those of automated keratometry (AK) and IOLMaster (keratometry) at the Assaf Harofeh Medical Center.

The mean interdevice differences in keratometry for Pentacam vs AK, Pentacam vs IOLMaster, and AK vs IOLMaster were −0.046 diopters, −0.471 diopters, and −0.424 diopters, respectively. Measurements of keratometry by the IOLMaster differed statistically significantly from those of Pentacam (P < .01) and AK (P < .01). For measurement of keratometry, 95% limits of agreement …
