Early Changes in Corneal Epithelial Thickness after Cataract Surgery--Pilot Study.

Purpose: To assess early variations in central and paracentral corneal epithelial and non-epithelial thicknesses after uneventful clear corneal incision phacoemulsification.

Materials And Methods: Twenty patients with a senile cataract underwent coaxial phacoemulsification through a 2.75-mm-wide corneal incision created at 180° in a prospective cohort pilot study.

Comparison of central corneal thickness using optical low-coherence reflectometry and spectral-domain optical coherence tomography.

Purpose: To assess intraobserver and interobserver reliability of central corneal thickness (CCT) measurements using optical low-coherence reflectometry (OLCR) technology and its agreement with spectral-domain optical coherence tomography (SD-OCT).

Setting: Rio Hortega University Hospital, Valladolid, Spain.

Design: Evaluation of diagnostic technology.

Precision of high definition spectral-domain optical coherence tomography for measuring central corneal thickness.

Purpose: This study was intended to assess the reliability of central corneal thickness (CCT) measurements using Cirrus high-definition optical coherence tomography (HD-OCT) in healthy subjects and its accuracy compared with ultrasonic pachymetry.

Methods: Seventy-seven consecutive subjects were recruited for evaluating repeatability, and agreement between two examiners. To analyze repeatability, one examiner measured 77 eyes four times in succession.
