Assessment of an algorithm-based combination device for objective and subjective refraction: accuracy and efficiency across examiner experience levels.

ABSTRACT:

Purpose

A novel combination device for objective and subjective refraction was assessed regarding repeatability, reproducibility, validity, vision quality, and timing for experienced and untrained examiners.

Methods

Six examiners (each three trained optometrists and untrained examiners) examined 33 healthy participants for objective and subjective refraction. The ZEISS VISUCORE 500 (VC) objective and subjective refraction combination device with an algorithm-based guided and regular custom mode was compared to a conventional control procedure (wavefront aberrometer and phoropter).

Results

For the objective measurement of spherical equivalent refractive error (SE), VC shows good repeatability (≤ ±0.29 D) and reproducibility (≤ ±0.28 D) across all examiners versus contr
