Contact Lens Update

• Issue 11 | November 2012

  Solutions

  Good care and maintenance are essential components of contact lens wear, and modern lens care systems have evolved to provide better comfort and antimicrobial efficacy. In this issue of Contact Lens Update, Percy Lazon de la Jara reviews the recent history of lens care systems and considers the factors necessary for optimal lens care; Daniel Tillia looks at associations between solution induced corneal staining, corneal infiltrative events and  case contamination, and reviews an article on the efficacy of contact lens solutions against three types of bacterial biofilm (Szczotka-Flynn, 2009); and Maria Markoulli relays the case of a patient who developed solution-induced corneal staining and bilateral asymptomatic infiltrative keratitis.

  • Feature Article - How effective are contact lens care solutions?
  • Conference Highlights - Associations between solution induced corneal staining, corneal infiltrative events, and Gram-­negative bacteria case contamination

  Spotlight on Scleral lenses

  Scleral lens design and technology have come a long way since their introduction, 125 years ago. Originally manufactured in glass and PMMA, these lenses are now available in more oxygen permeable materials with updated manufacturing techniques, allowing for longer wearing times, easier lens fitting, improved comfort and better ocular health. This issue of Contact Lens Update describes the current landscape of scleral lens fitting and its implications for patients with irregular corneas.

  • Feature Article - Importance of scleral contact lenses in clinical practice: A review
  • Conference Highlights - Jupiter Scleral Lenses: The UC Davis Eye Center experience
  • Clinical Insight - Scleral silicone hydrogel contact lens as a therapeutic contact lens

  Drug delivery via contact lenses

  Contact lenses able to deliver drugs via the eye will revolutionize patient care. In this issue, Alex Hui provides an overview of past and current research; Chau-Minh Phan reviews a study investigating the use of contact lenses to deliver cyclosporin A as a dry eye treatment (Peng and Chauhan, 2011); Anthony Soluri reports success in delivering ketotifen fumarate to the eye via contact lenses; and Alisa Sivak reports on Noel Brennan’s BCLA talk about the regulatory hurdles facing this new technology.

  • Editorial - Contact lenses for drug delivery – overview and recent developments
  • Feature Article - Delivering cyclosporine A from contact lenses: An article review
  • Conference Highlights - Ocular delivery of ketotifen fumarate by silicone hydrogel and conventional hydrogel contact lens materials
  • Clinical Insight - Barriers to drug delivery via contact lenses: A report from the 2012 BCLA meeting

  Ocular allergies

  Ocular allergies can have a significant impact on our patients — particularly those who wear contact lenses. In this issue of Contact Lens Update, James Wolffsohn and Paramdeep Singh Bilkhu explore ways of helping patients maintain contact lens wear despite allergies; Bernardo Cavalcanti and Candice Williams demonstrate the use of confocal microscopy to investigate corneal and conjunctival changes in patients with ocular allergies; Fiona Soong reviews an article (Mark Abelson, 2003) on the pathophysiology of ocular allergies; and Ulli Stahl and Jalaiah Varikooty demonstrate slit lamp techniques differentiating folliculosis from phlyctenulosis.

  • Editorial - Maintaining contact lens wear in patients with allergic conjunctivitis
  • Feature Article - Pathophysiology of allergic eye disease
  • Conference Highlights - In vivo confocal microscopy as a tool to evaluate cellular changes in the cornea and conjunctiva in ocular allergy and non-allergic ocular inflammatory diseases
  • Clinical Insight - Visualization of limbal/conjunctival folliculitis associated with soft contact lens wear
