Purpose: To develop a portable fundus camera based on the Living Lab method.
Methods: We developed a portable fundus camera using Living Lab methodology. For user-centered design, initial specification of the fundus camera was determined based on the result of a questionnaire by the Korean Retina Society members, and a trial product was manufactured. To verify its usability and clinical usefulness, a second living lab group was constructed. It was comprised of six centers (three University hospitals, two private clinics, and one health welfare social cooperative). Fundus images of 320 volunteers were taken; the photographs were evaluated by one retina specialist. Inspectors in six centers answered questionnaires after using the trial product. The manufacturer produced a prototype based on user evaluation of the trial product and the efficiency of the photographs.
Results: The questionnaires showed that the requirements for the fundus camera were low-cost, high pixel count, autofocus, weight of about 1 kg, and a nonmydriatic design. Three hundred and twenty photographs were taken using the trial product and detection of readable fundus photos was 81.56%. Thus, the first prototype camera was made based on user needs identified by questionnaires.
Conclusions: A user-centered/user-driven fundus camera was developed that showed a favorable clinical usefulness. The Living-lab method enabled the incorporation of user-driven requirements into the process of developing a portable fundus camera. This case suggests the applicability of the Living Lab method for developing medical instruments.
