Lab measurements in clinical practice

Laboratory tests designed to optimize ocular health and comfort with contact lens wear have direct relevance to clinical practice. In this edition of Contact Lens Update, Andrew Pucker provides an overview of properties that can have an impact on the wearing experience; Stephanie Wong reviews a 2013 article by Campbell et al. that compares methodologies used to measure contact angle; and Hendrik Walther relates the evolution of a more realistic in vitro eye model for testing contact lenses. Download our research brief clarifying the meaning of oxygen permeability vs. oxygen transmissibility, modulus, contact angle and coefficient of friction.
