The study aimed to explore how visual function is related to various factors like corneal scatter, higher-order aberrations (HOAs), and severity grading in patients with Fuchs endothelial corneal dystrophy (FECD).
It involved an analysis of 49 eyes from patients with FECD and 10 healthy eyes, assessing visual acuity and contrast sensitivity while examining several explanatory variables, including corneal thickness and HOAs.
Findings revealed significant correlations between visual function and factors like modified Krachmer grade and corneal densitometry, identifying specific threshold levels that correlate with decreased visual function in FECD patients.
