Contact lens -associated corneal infiltrative events (CIEs)

contact lens -associated corneal infiltrative events (CIEs)

• the main corneal pathological entities associated are known as contact lens-associated corneal infiltrative events (CIEs). These include (1):
  • microbial keratitis (MK)
  • contact lens-induced peripheral ulcer (CLPU)
  • contact lens-induced acute red eye (CLARE)
  • infiltrative keratitis (IK)
• factors associated with an increased risk of CIE include (2)
  • lens type (greatest risk for extended-wear hydrogel lenses than daily wear hydrogel lenses)
  • sex -males are more suceptible
  • smoking
  • late winter months
• Clinical presentation of CIE includes
  • eye soreness - commonest
  • irritation
• Management of contact lens-associated corneal infiltrative events (CIEs) (1)
  • lens wear should be suspended
  • contact lens solutions discontinued
  • anti-microbial therapy initiated immediately
  • changes in contact lens wearing schedules, and materials
  • referred to ophthalmologist immediately (3)
