In this presentation from AAO 2016, Dr. Julie Woodward provides an overview of fillers, from their estimated market growth in recent years to techniques for ensuring successful use. She explains how the elasticity or stiffness, known as the G' measure, varies between the various approved fillers, and how this attribute affects the optimal use of each device.
