Lens Solution Sensitivity

Symptoms

  • Itching, burning and /or stinging
  • Redness

Signs

  • Bilateral conjunctival hyperemia. Sometimes a pannus of blood vessels infiltrating the cornea may be observed

Etiology

  • Any preservative can potentially lead to an immune reaction and sensitization may take months or years
  • Most common with hydrogel lens wear
  • Rapid reaction after lens insertion in sensitized patients; infiltrates may be seen within 24 hours

Prevalence

  • Rare with modern preservatives

Differential Diagnosis

Management

  • Use non-preserved solutions and/or hydrogen peroxide based solutions
  • Ensure lenses are replaced at appropriate intervals
  • Redness and irritation usually subside within 48 hours of lens removal; infiltrates take at least one week to resolve. Vessel infiltration will take months to resolve
  • Cease lens wear until infiltrates resolve (if present)
  • Consider minimal maintenance options such as DD lenses
