The study aimed to assess the efficiency, efficacy and satisfaction of a redesigned portable corneal topography system to identify design solutions for system improvement. Twelve participants had to complete different tasks interacting with the software and the other elements of the system in a controlled scenario. After, a Retrospective Think Aloud was carried out focusing on the most challenging tasks during the system interaction. Finally, a satisfaction questionnaire was used to assess user perception. The most frequent errors and difficulties were identified along with the participants’ insights into the design elements for improvement of the system. Design solutions were generated to address software deficiencies and to improve the design of all aspects of the system. Usability analysis of software showed high relevance in the correct usage of the entire system, and along with the quick guide provides most of the feedback to understand the proper use of the handheld device.
