Repeatability, Reproducibility, and Agreement of Two Scheimpflug-Placido Anterior Corneal Analyzers for Posterior Corneal Surface Measurement

摘要

PURPOSE: To evaluate the intraoperator repeatability and interoperator reproducibility of two Scheimpflug-Placido anterior corneal analyzers (Sirius; Costruzione Strumenti Oftalmici, Florence, Italy, and TMS-5; Tomey, Nagoya, Japan) for the measurement of posterior corneal surface in normal eyes and the agreement between the two devices.
