Novel VR system for refractive error measurement demonstrates high reliability

A light field virtual reality (LFVR) system has been validated as a reliable tool for measuring refractive errors in the human eye, showing strong agreement and high repeatability when compared to traditional methods, according to a study.

The study included 50 participants who underwent refractive error assessments using both the LFVR system and traditional methods such as closed-field and open-field autorefractors, retinoscopy, and subjective refraction.

The findings revealed a strong agreement between the LFVR system and conventional methods, with intraclass correlation coefficients (ICC) for spherical equivalent (SE) measurements ranging from 82.7% to 86.7% and for focal line measurements (F1 and F2) ranging from 80.7% to 86.4%. The system also demonstrated high intra-repeatability, with ICC values of 88.8% for F1 and 97.5% for F2.

These results suggest that the LFVR system could be a reliable tool for refractive error measurement in optical care.
