Since 2018, the ophthalmic hospital of Lausanne has greatly participated in the installation of diagnostic and operating devices (Zeiss microscope) for cataract operations. Students thus benefit from equipment for their training and patients can finally be consulted in an optimal way and operations can be done in complete safety. A very special thank you to the entire team of bio-medical engineers at Jules Gonin's ophthalmic hospital and their employees for collaborating and working on the donation of all this equipment. (operating microscopes, phaco machines for cataracts, tonometers, slit lamps, pachymeter, video cameras mounted on a microscope for teaching, video recorder for operations ....)
