Uncorrected Visual Acuity (UCVA) [ Time Frame: 6 Months after surgery ]
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.
uncorrected and best distance corrected visual acuities (UCVA and BDCVA) [ Time Frame: Before surgery;1 Day,1 Month,3 Months and 6 Months after surgery ]

Questionnaire Results [ Time Frame: 6 Months ]
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).
