  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.

  • 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

  Kids & Contact Lenses

  Research has shown that children as young as eight can successfully handle, care for and wear contact lenses, particularly with the availability of new materials and daily disposable lenses. So why are so few children being fitted? In this issue of Contact Lens Update, Jeff Walline explores some of the myths that may discourage clinicians from prescribing contact lenses for young children, and Lindsay Paquette reviews a 2011 article by Chalmers et al., which explores risk factors for corneal and inflammatory events in young soft contact lens wearers. Check out Beth Kinoshita’s ARVO 2012 poster reviewing minus soft contact lens power progression in young myopes – and don’t forget to have a look at a new resource from the Centre for Contact Lens Research: an information handout for parents.

  One-day silicone hydrogel lenses

  Are daily disposables the Holy Grail of contact lens wear or do they have their own set of problems? In the latest issue of Contact Lens Update, Eric Papas looks at the growing popularity of this modality worldwide, Isabelle Jalbert examines their use as bandage lenses, Michael Spyridon explores their utility for patients who have difficulty wearing other types of contact lenses, and Jennie Diec reviews the risk of contamination associated with re-use of a daily disposable lens.

  • Editorial - The daily disposable takeover
  • Feature Article - Contamination of re-used daily disposable contact lenses: A Review
  • Conference Highlights - Refitting ‘problem’ reusable contact lens wearers with daily disposable lenses
  • Clinical Insight - One-day silicone hydrogel as a therapeutic lens in a severely symptomatic case of meibomian gland dysfunction
