At the start of this year, Optician published the final part of the Essential Contact Lens Practice series. In part six of this series, Dr Rachel Hiscox and Robyn Marsden discussed the topic of lens selection and included information about the properties of lens materials and what might influence the initial choice for any given patient.1 Their review of the literature showed that, as well as oxygen transmissibility (which has tended to dominate decision about material choice), factors that also need consideration when making this choice include:

  • Deposition
  • Modulus
  • Coefficient of friction
  • Wettability

In part 12 of the series, Dr Rachel Hiscox and Dr Sandeep Dhallu offered an overview of the aftercare routine.2 Included in this review was referenced information about signs and symptoms that might be reported by or seen on a patient that warranted a review of their current contact lens and when a change to a different type of lens might be appropriate.

Discussion

In this exercise, the article acts as source material for a discussion. It is available in our CET online area where, after again familiarising yourself with the articles mentioned, you will then be asked to answer some multiple choice questions. Once completed successfully, you will then be asked to undertake a discussion with a similarly qualified colleague concerning the following case scenario.
