Subbaraman1, Lyndon Jones1 1School of Optometry and Vision Science, University of Waterloo, 2Medella Health Current in vitro models for evaluating contact lenses (CLs) and other eye-related applications are severely limited. The presented ocular platform simulates physiological tear flow, tear volume, air exposure and mechanical wear. This system is highly versatile and can be applied to various in vitro analyses with CLs.
