Study of Algorithm-Assisted Subjective Refraction Software for Children Ages 6 to 12 Using Vision-R and Vision-S Phoropters

What this Trial Is About

Researchers are evaluating a new algorithm-assisted subjective refraction software designed specifically for children aged 6 to 12 years. This study aims to compare the accuracy of two versions of this software, each used with Vision-S and Vision-R phoropters, against the conventional subjective refraction method performed manually with the Vision-R phoropter. The research focuses on improving the standardization and accuracy of refraction assessments in children. The study has two phases Phase A will validate the first version of the Kids refraction software vA and Phase B will evaluate the second version vB, which includes additional steps to help manage the childs attention and cooperation. Participants will undergo subjective refraction tests using both software versions with Vision-R or Vision-S devices, as well as conventional subjective refraction with Vision-R. Measurements will be taken under non-cycloplegic conditions, with some assessments also performed under cycloplegic conditions. Participants will have their visual acuity and refraction results assessed multiple times, including Sphere, Cylinder, and Axis measurements, starting from Day 1 and continuing up to 7.5 months. The study includes comparisons between non-cycloplegic and cycloplegic refraction results using various devices. Researchers will monitor visual acuity throughout the study to evaluate the softwares performance. The total duration of participation for each child will be approximately 7.5 months.
