Retinal reconstruction from peripheral biometry.

Abstract

This study presents a method for retinal reconstruction using peripheral biometry. The incident beam is presumed to be directed toward the center of curvature of the anterior cornea, reaching the retina with minimal deviation. A significant advancement is demonstrated by extending previous approaches to three dimensions and effectively capturing the complexity of astigmatic corneal surfaces. The method was evaluated in Zemax using Navarro's eye model featuring a retina of 12 mm radius, across various levels of accommodation ranging from 0 to 8 D, and a visual field angle between 25 and 25°. The method's reliability diminishes for field angles ≥ 35°. Validation was carried out using 500 synthetically generated eyes, and the method's performance was also assessed with an ellipsoidal retina. The findings revealed that spherical equivalent differences were consistently under 0.25 D at 25° for both types of retinas. Overall, these results demonstrate the method's effectiveness, offering a promising new tool for retinal reconstruction.
