Resolving the OcuCheck: A Human-Centered Design Approach

Abstract

The OcuCheck is a point-of-care device that uses nanotechnology to quantify specific biomarkers in the tear film that result from micro leaks from the corneal wound after a serious eye trauma or surgical incision. Current methods for evaluating corneal wounds or injuries require specific training and access to a Slit Lamp, a large, immobile device that is not typically available outside of the clinical setting. To complement the novel technology housed within the device the design of the OcuCheck needed to be more accessible than the Slit Lamp. Design, research, and prototype testing were focused upon use of materials, patient needs, ease of use, scale, location of device when not in use, and product protocols. Rather than simply creating a utilitarian solution we strove to pre-empt usability and implementation challenges through use of empathy. This device has the potential to disrupt the healthcare industry by creating a product that incorporates the patient’s physical and emotional comfort into the design.
