Feedback: BCLA CLEAR interactive – 7

In Optician's April issue, Wendy Sethi offered an overview of the key points from the BCLA CLEAR publication, which focused on the interactions between lens materials, care products and the tear film, looking at the biochemistry and compatibility of the various elements involved in successful contact lens wear.  

Two important areas discussed, which are both of clinical relevance when undertaking an aftercare assessment, were the provision of oxygen to the cornea via a contact lens and the wettability of the contact lens material during wear. 

This exercise was designed to explore how changing a contact lens material for one reason, such as improving oxygen transmissibility, may have an impact upon wettability.
