Total score 60.41 ± 24.81 90.16 ± 10.91  < 0.001
Far distance 61.55 ± 22.98 89.70 ± 13.03  < 0.001
Intermediate distance 68.89 ± 26.63 97.50 ± 7.01 0.001
Near distance 58.00 ± 30.17 86.00 ± 14.78 0.004
  1. Mean scores of the patients before the exchange of a multifocal IOL and after the exchange to another multifocal IOL. The greater the score (maximum 100), the better is the visual function. SD = standard deviation
