Currently I am working in a medical device company that focuses on vision electrophysiology. The overall purpose of these vision testing systems is to aid optometrist and ophthalmologist diagnose their patients and use these devices for early detection. The two modalities we currently use is vision evoked potential (VEP) and electroretinography (ERG). While working in this company, i took part of their quality control and technical support for these devices. As the professor mentioned in the prior lectures, it is key to provide support to a medical device once it is released to the market, it plays a huge role when it comes to the customers.
