Accuracy and precision of automated subjective refraction in young hyperopes under cycloplegia.

Purpose: To assess the agreement between the Eye Refract, an instrument to perform subjective automated refraction, and the traditional subjective refraction, as the gold standard, in young hyperopes under noncycloplegic and cycloplegic conditions.

Methods: A cross-section and randomized study was carried out, involving 42 participants (18.2 ± 7.

A Comparison between Automated Subjective Refraction and Traditional Subjective Refraction in Keratoconus Patients.

Significance: The performance of the Eye Refract (Luneau Technology, Chartres, France), a new instrument to perform aberrometry-based automated subjective refraction, has been previously evaluated in healthy subjects. However, its clinical implications in other ocular conditions are still unknown.

Purpose: The purpose of this study was to evaluate the agreement between the Eye Refract and the traditional subjective refraction, as the criterion standard, in keratoconus patients with and without intracorneal ring segments (ICRSs).
