Validation of the Vision Trainer Clinical Decision-Support Software:A Randomized Comparison of Software-Guided Subjective Refraction(JCC and Non-JCC Algorithms) Against Unassisted Manual Refraction
University of Pennsylvania
Summary
This study is a prospective, randomized, crossover clinical investigation designed to evaluate the accuracy, efficiency, and usability of the Vision Trainer software for subjective refraction. The study compares software-guided refraction, implemented using both Jackson Cross Cylinder (JCC) and Non-JCC workflows, against standard unassisted manual refraction performed by trained examiners
