Ortho-K Overnight Lenses

Risk-free Alternative to Laser Eye Surgery

Ortho-K overnight lenses correct vision without the need for contact lenses during the day. This is made possible by a specially designed Ortho-K contact lens that reverses the power of the cornea at the front of the eye during overnight wear.

Once the full effect of the Ortho-K process has taken place the eye is effectively ‘normal’ and can see clearly during the day. Once one stops wearing Ortho-K lenses the eye goes back to normal, making them a truly great and risk free alternative to laser eye surgery.

Charles Babumba explains Optomap Retinal Scanner on SBTV (Brazil)

The changes to the cornea experienced by wearing Ortho-K lenses are reversible. Although laser eye surgery is quite a safe procedure, there is always a possibility of having one or more following problems after having surgery, which may remain permanent:

  • Dry eyes
  • Ghosting effect
  • Regression, especially for higher prescriptions
  • Night vision problems
  • Over/under correction

On the other hand, changes to the cornea using Ortho-K lenses are reversible, so when you stop using them your prescription goes back to the original one within a few days or weeks.

Who can benefit from Ortho-K?

Ortho-K is ideal for low to mid-short sighted people who:
  • Find soft contact lenses do not provide the comfort required for their life-style
  • Take part in leisure activities in which contact lens wear isn’t ideal
  • Have considered refractive surgery but are concerned about the risks
The benefits of Ortho-K are:
  • Freedom from contact lenses and glasses during the day
  • Only overnight lens wear required
  • Comfortable semi-permeable alternative for the correction of short shortsightedness
  • Safe and reversible vision correction therapy without surgery
Requirements for Ortho-K:
  • A spherical prescription of -0.50D up to -11.00D and +0.50D to +6.00D
  • Astigmatism of up to -0.50D to -4.50D
How much does Ortho-K cost?

Ortho K is similar in price to wearing a pair of quality daily disposable lenses every day. The lenses require replacement every 6 to 12 months to ensure they provide optimum correction.

Will they work for me?

If suitable, an eye-mapping instrument will be used and lenses ordered from the data collected and progress will be monitored regularly until only 3-6 monthly assessments are required.
