Accelerated Orthokeratology « Welcome to Dr. David Ng and Associates – Trust the health of your eyes to us

AOK is a method of reshaping the cornea of the eye without surgery. Oxygen permeable contact lens are worn during sleep which flattens the cornea and reduces myopia (nearsightedness). These lenses are extremely comfortable and safe.

With the advances in AOK lens designs and computer assisted lathe production, we are able to reduce the myopia significantly in a matter of days. Within 7 days most patients achieve 20/20 vision without the use of any glasses or contact lenses during the day. Orthokeratology has been shown to control myopia and prevent further progression. The technique is extremely effective and well tolerated by children.

AOK technology is for you if:

  • You want myopia control.
  • You do water sports.
  • Dry eyes prevent you from wearing daily contact lenses.
  • You cannot have laser refractive surgery.
  • Your prescription is still changing.
  • You want to have a reversible corrective procedure.

Recent studies have shown that AOK controls the increase in the eye’s axial length (the greater the axial length, the higher the myopia) in children. This translates to lower prescriptions once the eye reaches adult maturity.

Myopia (nearsightedness) control and therapy « Welcome to Dr. David Ng and Associates – Trust the health of your eyes to us

However recent studies provide evidence that myopia increases when the peripheral retinal images are focused behind the retina (hyperopic defocus). This is the world’s first single vision spectacle lens design which uses the Peripheral Vision Management Technology. As the child and eye grows there is an attempt of the eye to bring the hyperopic defocus onto the peripheral retina.
