Contact lenses

Contact lens infections can lead to bacterial keratitis and red eye irritation. Also, in severe cases, infections caused by contact lenses can lead to blindness. Extended wear contact lenses therefore exacerbate these problems.

Perfectus Biomed can assess the both the antimicrobial and anti-biofilm efficacy of your product. We offer a range of testing methods and can therefore 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 in relation to microbial attachment

Perfectus Biomed use appropriate pathogens to carry out testing. If you require testing on a product that is not listed above then please contact us to discuss this.
