Accuracy of a low-cost, portable, refractive error estimation device: Results of a diagnostic accuracy trial

ABSTRACT:

Purpose

To assess the accuracy of refraction measurements by ClickCheckTM compared with the standard practice of subjective refraction at a tertiary level eye hospital.

Design

Diagnostic accuracy trial.

Methods

All participants, recruited consecutively, underwent auto-refraction (AR) and subjective refraction (SR) followed by refraction measurement using ClickCheckTM (CR) by a trained research assistant. Eyeglass prescriptions generated using ClickCheckTM and the resulting visual acuity (VA) was compared to SR for accuracy. Inter-rater reliability and agreement were determined using Intra-class correlation and Bland Altman analysis respectively.

Results

The 1,079 participants enrolled had a mean (SD) age of 39.02 (17.94) years and 56% were women. Overall
