Comparison of central corneal thickness measured with Orbscan and Pentacam.

Purpose: To compare central corneal thickness measurements obtained with Orbscan II using the acoustic equivalent correction factor (CF) and Pentacam in eyes screened for refractive surgery.

Methods: Central corneal thickness in 91 eyes of 51 volunteers with a spherical equivalent refraction ranging from -17.00 to +5.

Anterior chamber depth measurement before and after photorefractive keratectomy: comparison between IOL master and Orbscan II.

Purpose: To measure the anterior chamber depth (ACD) with 2 different devices before and after photorefractive keratectomy (PRK).

Design: Noncomparative case series.

Participants: One hundred forty-three eyes of 143 patients who had undergone PRK with refractive errors ranging from -13.
