Abstract Details

Purpose:

To understand the different visual profiles of patients based on the amount of near, intermediate, and far distance vision with the assessment of objective behavioral data provided by the visual behavior monitor (VBM; Vivior AG, Zurich, Switzerland) and to understand the consequences for the surgeon’s decision on visual correction.

Setting:

Medipol University Hospital, Istanbul, Turkey

Methods:

Patients who were candidates for presbyopia-correcting IOLs were fitted with a VBM and instructed to wear the device for 3 to 5 days, 8 to 10 hours per day. Patients returned at the end of this period, where the results were analyzed, and patients classified into different groups.

Results:

A total of 48 patients (mean age was 45.7 years (SD 11.09) were included in the analysis. The findings showed that the patients could be classified into four groups: a) 22,9% are near-dominant, i.e. use more that 40% near vision, , b) 27,1% are intermediate-dominant, i.e. use more that 40% intermediate vision, c) 31,2% are far-dominant, i.e. use more that 45% far vision and d) 9% were balanced, i.e. use near, intermediate and far vision proportionally.  No correlation could be found between the visual behavior and age of the patients.

Conclusions:

These first results clearly demonstrate the need for objective data to understand and group patients according to their different visual behavior.  Surgeons must understand the visual behavior of the patients to select the correct treatment and achieve improved outcomes in the use of presbyopia-correcting IOLs.
