Medical device design & User Experience for Cataract and Glaucoma Treatment at Carl Zeiss

Usability already optimized in early development phase

With the VISALIS 500, Carl Zeiss planned to launch a product innovation that would combine the most important devices for ophthalmic surgery in a single unit. Milani was involved in the early development phase to optimize the new medical device in terms of user-friendliness and to best meet the complex requirements. The challenge was that the surgical device had to be designed for different medical environments internationally. It had to be able to be operated by different people during surgical procedures, both in the sterile zone and outside.

To ensure excellent usability for all users, especially ophthalmologists and surgical assistants, Milani conducted needs assessments in various hospitals across Europe. Based on these findings, the user guidance was designed and optimized in an iterative process. Milani designed prototypes and tested them again and again with different users in diverse application contexts. The result is an ergonomically optimized surgical device that can be used flexibly in the sterile room and operated easily and comfortably by different players.
