SCIENTIFIC REPORT The usefulness of Vistech and FACT contrast sensitivity charts for cataract and refractive surgery outcomes research

Abstract

Aim: To investigate the repeatability and sensitivity of two commonly used sine wave patch charts for contrast sensitivity (CS) measurement in cataract and refractive surgery outcomes. Methods: The Vistech CS chart and its descendant, the Functional Acuity Contrast Test (FACT), were administered in three experiments: (1) Post-LASIK and age matched normal… (More)
