Optimization of a Photoretinoscopy Method for Determining the Objective Refraction of Children

Ametropia Clinical Trial

Official title:
Optimization of a Photoretinoscopy Method for Determining the Objective Refraction of Children With a Smartphone/add-on Device in Hong-Kong

Clinical Trial Summary

The objective is to compare the refractive parameters of the photorefraction prototype device without cycloplegia with the refractive parameters of reference device, an autorefractometer with and without cycloplegia.

Clinical Trial Description

A single visit will be necessary. After informed consent, and checking of the inclusion and exclusion criteria, investigators will perform measurements with an autorefractometer and with the photorefraction prototype device without cycloplegia followed by an objective refraction with an autorefractometer under cyclopegia. ;
