31,139 observed eyes across matching follow-ups
Percentages are results a study reported for its own patients, not a prediction for you. Where a study measured an outcome more than once, the latest matching follow-up is shown. “Not reported” means the study did not publish that number; it does not mean zero.
Share of checked eyes that could see 20/20 or better without glasses or contact lenses after treatment.
Share of checked eyes that landed within half a diopter of the correction the study aimed for.
Share of checked eyes that landed within one diopter of the correction the study aimed for.
