Abstract Details

Purpose:

To assess the accuracy of a surgeon’s prediction of the frequency of near, intermediate, and far distances requirements of patients requiring presbyopia-correcting intraocular lenses compared with the assessment of objective behavioral data provided by the visual behavior monitor (VBM; Vivior AG, Zurich, Switzerland).

Setting:

Medipol University Hospital, Istanbul, Turkey

Methods:

Patients who were candidates for presbyopia-correcting IOLs were evaluated using a questionnaire to predict the frequency of near, intermediate, and distance vision during a typical day. After the questionnaire, patients 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 compared to the questionnaire results.

Results:

A total of 23 patients (mean age was 44 years (SD 13.06) were included in the analysis. The findings showed that the individual patient predictions differed substantially in the evaluation between near, intermediate, and far vision assessed by the VBM. There was a low correlation (r2 = 0.304) between surgeon and VBM for near, a medium correlation (r2 = 0.527) for intermediate distance and a high correlation (r2 = 0.720) for far vision. However, the correlation between the surgeon prediction and the VBM data did not achieve statistical significance.

Conclusions:

These first results clearly demonstrate that a surgeon’s predictive abilities of patients’ visual requirements based on a verbal questionnaire, are no match for objective data based on a patient’s daily activities. The use of objective visual data, provided by the VBM, should result in improved outcomes in the use of presbyopia-correcting IOLs.
