FDA/AGS Workshop on Supporting Innovation for Safe and Effective Minimally Invasive Glaucoma Surgery, February 26, 2014

The Food and Drug Administration (FDA) is announcing the following co-sponsored public workshop entitled "FDA/American Glaucoma Society (AGS) Workshop on Supporting Innovation for Safe and Effective Minimally Invasive Glaucoma Surgery.”

The purpose of this workshop is to address the current challenges in the assessment of implantable minimally invasive glaucoma surgical (MIGS) devices with a focus on clinical trial design and conduct. Glaucoma experts will present evidence to better define the appropriate patient population, as well as the appropriate evaluation of effectiveness and safety for MIGS devices.  The primary goal of the workshop is to determine the best clinical trial design for MIGS devices in order to facilitate bringing these innovative technologies to the US marketplace.

Date, Time and Location

This meeting will be held February 26, 2014, beginning at 1:00 p.m. - 6:00 p.m. (materials may be picked up starting at 12:00 p.m.) at the following location:
