NCT03655743

Brief Summary

The development and validation of a concise, practical, on-line, self-administered, self-archiving, and self-scoring PRO questionnaire for routine clinical use in refractive surgery is the primary study objective. Secondary objectives are to gather outcome data from patients before and after surgery in each of the following domains comprising key elements of vision related quality of life: spectacle dependence; quality of vision; eye comfort; freedom; emotional well-being; and overall satisfaction with the results of surgery. Patients undergoing refractive surgery at Moorfields Private Outpatient Clinic will be enrolled in the study in the validation phase.
