  Myopia Control

  In response to rising awareness of myopia as an international public health concern, this edition of Contact Lens Update highlights promising advances in the field. Percy Lazon de la Jara provides an overview of myopia control techniques and reviews the case for retinal defocus; Paul Gifford and Kate Johnson describe one family's experiences using three different methods of correcting (and controlling) myopia; Sarah Guthrie reviews a paper (Anstice and Phillips, 2011) reporting encouraging results with dual-focus soft contact lenses; and Lindsey Paquette reports the results of a study demonstrating that children and youth are more than capable of wearing and caring for contact lenses.

  • Feature Article - Effect of dual-focus soft contact lens wear on axial myopia progression in children
  • Conference Highlights - Ease of contact lens fitting and training in a child and youth population

  Presbyopia

  Contact lens manufacturers have responded to an aging worldwide population by working to develop more  effective contact lenses designed to correct presbyopia. In this edition of Contact Lens Update, Jill Woods relays the results of a study designed to compare objective consulting room tests with wearers’ “real life” experiences with monovision and multifocal lenses; Tony Chahine relays his approach in fitting lenses for a young presbyope with a high-performance, visually demanding job; Pauline Xu reviews a paper (Morgan et al. 2011) exploring the results of an international contact lens fitting survey; and Craig Woods explores the positive results of fitting patients with presbyopic correction.

  • Editorial - Presbyopia: a pause in focus
  • Feature Article - A review of an international survey of contact lens prescribing for presbyopia
  • Conference Highlights - Medium-addition, centre-near, silicone hydrogel multifocal lens compared to monovision: performance, adaptation and preference
  • Clinical Insight - A case report in the refitting of a presbyopic patient from monovision to aspheric multifocals, and then ultimately to translating RGP bifocals

  Compliance and non-compliance

  According to the research literature, we've been concerned about how well patients follow guidelines for safe contact lens wear and care for decades. In this edition of Contact Lens Update, Kathy Dumbleton and Lyndon Jones review that literature and outline the risks associated with specific areas of non-compliance; Alisa Sivak reports from the BCLA, with strategies for encouraging compliance; and Pauline Xu reviews a paper (Wu et al. 2011) exploring the best way to clean a contact lens case. Don't forget to check out Healthy Soft Contact Lens Habits, a resource developed by the Association for Optometric Contact Lens Educators.

  Lens care

  Though widely popular, multipurpose contact lens care systems on the market today may not be as effective as we would like, particularly when it comes to cleaning and disinfecting lens cases. In this edition of Contact Lens Update, Mark Willcox explores the efficacy of dual-disinfectant care systems, Doerte Luensmann reviews a paper (Zhao 2010) investigating whether there is a  link between adverse events and lens deposits, Gareth Ross clarifies the role of surfactants and other components of lens care systems and Daniel Tilia tells us what can happen when the quest for convenience clashes with lens of choice and recommended lens replacement frequency.

  • Editorial - Multipurpose disinfection solutions: New challenges, new products, new ingredients, new tests
  • Feature Article - Physiological response to protein and cholesterol deposition on silicone hydrogel contact lenses
  • Conference Highlights - Link between cleaning efficacy and physical properties of multipurpose solutions
  • Clinical Insight - Matching lens care systems with patients
