  It's A Question of Comfort

  Is contact lens discomfort still a problem? We checked in with some of the world's leading experts. In this edition of Contact Lens Update, Eric Papas and Nancy Keir weigh in on the depth of this issue as it stands today, Robin Chalmers explores the effects of refitting struggling lens wearers with daily disposables, and Nancy Keir reviews a 2006 paper exploring the similarities and differences between dry eye and contact lens-related dry eye. Don't forget to download our Research In Brief, which reviews the link between comfort and terminology used to characterize the surface properties of a contact lens.

  Let's talk about SICS

  Solution-induced corneal staining (SICS) has been a hot topic since the first reports in 2002, but what does the latest research tell us? In this edition of Contact Lens Update, Maud Gorbet explains what we know about the cellular mechanism of this controversial topic, Cameron Postnikoff reviews a 2011 article that contradicts earlier theories of the staining mechanism behind SICS and Jill Woods describes the results of a pilot study investigating symptoms associated with SICS as well as its typical presentation pattern.

  Conjunctival Controversies

  A number of contact lens-related conjunctival findings have been highlighted in the research literature over the last decade, including lid wiper epitheliopathy, conjunctival flaps, lid-parallel conjunctival folds and conjunctival indentation. In this issue of Contact Lens Update Cécile Maissa provides an overview of their presentation, location and presumed mechanical causes as well as their possible effect on comfort, Jalaiah Varikooty shares slit-lamp videos and images highlighting the clinical appearance of these findings, Sruthi Srinivasan reviews a paper by Korb et al. (2002) describing a study evaluating whether dry eye symptoms are associated with LWE in contact lens wearers, and Lyndon Jones’ team describe the results of a lid wiper study carried out in a low humidity environmental exposure chamber.

  • Editorial - Contact lens interaction with the conjunctiva and its influence on comfort
  • Feature Article - Lid wiper epitheliopathy and dry eye symptoms in contact lens wearers: A review
  • Conference Highlights - The evaluation of lid wiper epitheliopathy in contact lens wearers in a controlled low humidity environmental exposure chamber
  • Clinical Insight - Clinical images: Lid wiper epitheliopathy, conjunctival flap, lid-parallel conjunctival folds and conjunctival indentation
