The Benefits

Does Ortho-K have any advantages over laser surgery (LASIK)?


  • The prescription does not need to be stable for 1-2 years before undergoing treatment.
  • It does not cause the permanent hazy vision experienced by some patients following laser surgery caused by scarring.
  • Changes in prescription over time can be dealt with without further surgery.
  • The procedure is reversible (laser is not).
  • There is a very significant understanding of the effects of contact lens wear on the cornea, because of the many years of lens use. LASIK long term effects are not completely understood.
  • There is no post-operative pain or recovery period.
  • Ortho-K is significantly cheaper.
  • Ortho-K does not preclude surgery in the future.

What are the advantages of Ortho-K?

  • Good vision without spectacles or contact lenses for most of the day.
  • It is not a surgical procedure.
  • It is reversible.

  • It slows down the increase in myopia in children.
  • Using well established contact lens fitting techniques mean there are very few risks.

What are the disadvantages of Ortho-K?

  • You must be prepared to allow 4-6 visits over 3-6 months.
  • Continued lens wear is essential or the cornea will revert to its original shape.
