Anterior chamber depth measurement in pseudophakic eyes: a comparison of Pentacam and ultrasound.

Purpose: To compare the anterior chamber depth (ACD) measurements of a Scheimpflug camera (Pentacam, Oculus Optikgeräte GmbH) and immersion ultrasound biometry (UltraScan Imaging System, Alcon Laboratories) in pseudophakic eyes.

Methods: This prospective, multicenter study included three independent sample groups. The ACD, defined as the distance between the corneal epithelium and intraocular lens anterior surface, was assessed by ultrasound biometry.
