120/403: Vision Assessment Device (Multidisciplinary Team)

Many presbyopes with age-related farsightedness require multifocal lenses to correct multiple refractive errors (near and farsightedness). After initial screening, prescribing multifocal lenses relies on a heuristic approach, requiring patients to try their lenses before reporting visual issues. We need a more effective method to determine prescriptions for multifocal lenses in presbyopic eyes, measured by fewer return appointments for fittings or post-fitting surveys assessing fit quality. We designed the Apex Viewer to simulate how multifocal lenses work in real-life environments. Users look through a goggle apparatus to see an image on a screen. Through subjective input, trained personnel adjust the images until they determine a prescription. By mimicking the reality of vision with the patient’s multifocal prescription, patients can experience faster, more effective fittings and require fewer return office visits. We aimed to improve device ergonomics by modifying the initial prototype to include an adjustable apparatus and accommodate a greater range of face sizes.
