Contact lenses

Contact lens infections can lead to bacterial keratitis and red eye irritation and in severe cases blindness. These problems can be exacerbated with the use of extended wear lenses.

In order to demonstrate the antimicrobial and anti-biofilm efficacy of your product we will carry out testing on:

  • Contact lens solutions
  • Antimicrobial coated lenses
  • Silica lenses
  • Hydrogel lenses
  • Contact lens coatings
  • Surface structure in relation to microbial attachment
  • Protein accumulation on contact lenses in relation to microbial attachment
  • Other – please contact us to discuss.

All of our testing can be carried out against appropriate pathogens

We offer a range a standard test methodologies including:

  • ISO 14729: Microbiological requirements and test methods for products and regimens for hygienic management of contact lenses
  • ISO 14730: Antimicrobial preservative efficacy testing
