Abstract Details

Purpose:

To evaluate if the Visual Behaviour Monitor (VBM, Vivior AG, Zurich, Switzerland), which provides objective data of a patient’s daily visual activities and lifestyle, does impact a surgeon’s decision making in intraocular lens selection in patients scheduled for cataract surgery or refractive lens exchange.

Setting:

Five-center feasibility study in Ireland, Germany and Switzerland

Methods:

The VBM is a unique wearable that can track a patient’s visual lifestyle using a combination of sensors measuring working distances, ambient light, head movement and position, resulting in an objective evaluation of the patient’s visual activities. This study sought to determine if the effect of VBM results influenced the surgeons’ decision-making process. The study compared IOL selection following the VBM results, compared to historical IOL implantation data of each surgeon. Patients were randomly selected for enrolment and were not screened for a pre-existing interest in a premium IOL.

Results:

In an initial analysis of the first 23 patients enrolled at one center (Dublin, Ireland) for cataract surgery or refractive lens exchange, of the 45 eyes undergoing surgery, 66% of eyes (n=30) were implanted with a trifocal or multifocal IOL, with 27% implanted with a monofocal IOL (n=12) and 7% with a toric IOL (n=3). These results were compared to a 2-week period of cataract and refractive lens exchange surgery at the same center where of the 45 eyes undergoing surgery, 44 were implanted with monofocal IOLs and one with a premium IOL.

Conclusions:

In this initial feasibility study, once patients had worn the visual behaviour monitor and understood their own personal vision needs, agreed to opt for a presbyopia-correcting IOL at almost 15 times the previous rate seen at this clinical site. Further, in this initial analysis, PC-IOL use increased from <5% to >75% in patients who had worn the VBM.
