Abstract

This study aimed to identify design and usability issues of a portable corneal topography device, its software and manual. A usability test with a think aloud protocol was carried out by sixteen experienced optometrists. After using the device, the PSSUQ and SEQ questionnaires were applied. The results show a positive mean score for all the usability dimensions, being the top three elements of the higher evaluation the interface quality, usefulness and overall satisfaction. Further, based on the results it is possible to improve the device design by reducing the size of the handgrip and changing the location of control for image capturing. Results also allow enhancing the feedback provided by software when using the device and organise better the information in its manual. Overall, this study strengthens the idea that implementing usability tests as a key element on the design process to recognizing the user’ needs, and thus, improving medical device systems.
