I presume that you're aware of The American Academy of Ophthalmology. It is the primary conference where all the key players (researchers, distributors, practicing physicians, competitors) attend. https://www.aao.org/annual-meeting/past-and-future-meetings

I was on the development team for a company that sold Optical Coherence Tomography and ultrasound devices in the Ophthalmology market. If you need assistance in getting your device FDA certified - I can provide consulting assistance.
