User Friendliness of a Wearable Visual Behavior Monitor for Cataract and Refractive Surgery

Abstract: A prospective feasibility study was conducted to determine whether a new wearable device, the Visual Behavior Monitor (VBM), was easy to use and did not present any difficulties with the daily activities of patients. Patients for cataract surgery and refractive lens exchange were randomly selected and screened for inclusion in the study. A total of 129 patients were included in the study as part of a multicenter study. All measurements were performed before surgery. Upon inclusion, patients were trained to wea… Show more

“…It is conceivable to weight the retrieved parameters with factors accounting for the importance of time spent by the patients on near, far, daytime or nighttime activities, requiring stereovision or benefiting from constant visual quality. The information from these weights could be extracted, from lifestyle questionnaires or devices attached to the patient that measure light exposure and work distance over a period of time 32 .…”

“…An exposed recharge port also means the device is not water resistant, which would not be ideal for a preschool population. The Vivior 25 is another recently developed device for measuring visual behavior in adult patients undergoing cataract and refractive lens exchange surgery to improve treatment outcomes. This device, however, is designed to be used short term and only has a recording capacity of 16 hours, which would not be ideal for amblyopia treatment monitoring.…”

“…With recent technological advancements in myopia research, a number of wearable devices have been developed to provide real-time objective measures of light intensity, physical activities, and distance to reading material through use of light, gyroscopic, acceleration, and infrared sensors. 24 , 25 These sophisticated multifunctional devices are designed to fit a variety of frames, but again are not designed to specifically measure spectacle adherence. The devices require regular recharging, posing a burden on parents to remember to recharge the device, which risks lost data.…”

“…Measured illuminance also depends upon the location and orientation of the illuminance meter. The illumination that contributes to the retinal image can be estimated by mounting a forward-viewing light meter, near the eye [22,23]. The integration angle of such forward-viewing measurement devices should not exceed the angular area of the human visual field (approximately 20,000 square degrees).…”

“…Small ambient light sensors which can be mounted to the wrists, clothing, or incorporated into spectacle frames [17][18][19][20][21][22][23] have recently been employed to monitor light levels in children's environments and helped reveal that myopic children, on average, tend to be exposed to less light [8,24]. Since retinal illuminance depends on the eye pupil illuminance, which depends on the direction of the eye's line of sight, the ability of these light measurements to capture the features of the lighting environment relevant to eye growth is disputable.…”
