What are the disadvantages of Orthokeratology?

  • An overnight retainer lens is needed most nights (68% of patients only need to wear lenses alternate nights at 1 month from fitting)
  • You will need to use other vision correction for the first 2 weeks while the treatment takes effect
  • You will need to clean & disinfect the lenses every day on removal
  • There is a risk of eye infection if the lenses are not cared for correctly using the solutions advised
  • The therapy is NOT permanent
  • The therapy reduces its effect if the retainer lens is not worn. Your prescription increases by approximately -0.25DS per day, back to your eye's natural prescription over a few weeks
  • Most people become more short sighted in later life, and the lenses will need re-adjustment at that stage
