UDVA - Percentage
This graphs shows the distribution of post operative uncorrected distance visual acuity (UDVA). It shows the percentage of patient reaching a certain level of unaided visual acuity. It is one of the most important measure for patient happiness after the surgery.
Note that under 'Distant Visual Acuity' we offer a slightly different graph called 'Cumulative UDVA' which may be better represents the postOP UCVA distribution than the classical Efficacy graph. It is the same data, just adding up the percentage of each UCVA group from left to right, showing the percentage of eyes which achieve a certain VA level 'or better'.
