Rosen Symposium


The 16th Annual Rosen Symposium on Cataract & Refractive, originally to be held on Friday May 1st, 2020,

has been cancelled.




The Queen's University Department of Ophthalmology is excited to present the 16th Annual Rosen Symposium on Cataract and Refractive.

In the year “twenty twenty,” surely there is no better topic for the annual Rosen Symposium than cataract and refractive surgery!

Since many attendees may not be familiar with refractive surgery, a number of talks will be focusing on information relevant to comprehensive ophthalmologists and optometrists.  

As a change from previous years, this year's format will feature shorter presentations that will cover a wider range of topics in cataract and refractive.  Aditionally, in the afternoon we will be hosting an hour-long complicated case symposium where we discuss attendee-submitted videos/presentations (details to be announced soon).
