Outcomes

Primary Outcomes

Uncorrected Visual Acuity (UCVA)

Uncorrected Visual Acuity (UCVA) from surgery measured in logMAR. LogMAR is the "logarithm of the minimum angle of resolution". A lower logMAR value indicates better visual acuity.

Time frame: 6 Months after surgery

Secondary Outcomes

Questionnaire Results

Results of questionnaire rating the quality of distance vision without glasses or contact lenses. Measured on a scale of 0 to 6 (0 = worst, 6 = best).

Time frame: 6 Months
