Abstract Details


The satisfaction of patients with MF-IOLs depends on various factors. In individual cases a difference between both eyes of a single patient is not always easily explainable. When implanting an Mplus-IOL there is the question, which effect does a decentered position of the visual axis with respect to the pupil and to the position of the IOL have.


In one group of operated patients the decentration of the visual axis with respect to the pupil und to the refractive zone of the Mplus-IOL (transition zone between near and far) was detected, but the IOL has been placed according to the manufacturers recommendations. In a second group the detection of the visual axis was done preoperatively by checking the purkinje-reflex, and then during surgery the IOL was placed systematically with the near addtion opposite to the quadrant where the decentered visual axis was detected related to the pupil.


All post-operatively examined patients of the first group, where the visual axis passes through the transition zone, halos or other visual phenomena were reported. All patients of the second group, where the positioning of the Mplus-IOL was determined preoperatively according to the visual axis, the symptoms were significantly lower.


The detection of the location of the visual axis with afterwards positioning the reading zone according to the visual axis does increase the satisfaction of the patients and reduces significantly the optical effects.


When implanting a Mplus-IOL, the reading zone should be positioned in the opposite quadrant of where the location of the visual axis (determined by Purkinje-reflex) is. The result is that the visual axis passes through the distance zone of the IOL.
