  Scleral Lenses

  The applications of contemporary scleral lenses are wide-reaching, offering benefits to patients with irregular corneas, ocular surface disorders, intolerance of other contact lens designs as well as those with normal eyes. In this issue of Contact Lens Update, Melissa Barnett and Lynette Johns provide an overview of the history and modern applications of these lenses; Trevor Fosso presents the case of a patient fitted with scleral lenses as a treatment for a 69-year-old patient with Sjogren’s Syndrome; Lacey Haines summarizes a 2015 review examining the evidence supporting use of these lenses as a treatment for patients with dry eye symptoms. Download our research brief outlining the the ways in which these lenses can be prescribed in practice!

  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.
