Investigation of the Accuracy of a Low-cost, Portable, Autorefractor to Provide Well-tolerated Eyeglass Prescriptions

Refractive Errors Clinical Trial

Official title:
Investigation of the Accuracy of a Low-cost, Portable, Autorefractor to Provide Well-tolerated Eyeglass Prescriptions

Clinical Trial Summary

At the Aravind Eye Hospital (AEH) in Madurai, India, patients ages 18-40 receiving treatment for refractive error who choose to enroll in the study will be evaluated using subjective refraction and objective refraction, by way of the QuickSee autorefractor. Patients will then be randomized into one of two treatment plans: receive glasses from objective measure first then subjective measure second, and vice versa. After one week of wearing the first pair of glasses, patient preferences are assessed, and glasses are switched. After a week of wearing the second pair of glasses from the alternate measurement method, patient preferences are again assessed. Patients may then decide which pair patient like best. This is a double blind, case-crossover clinical trial.
