Ortho-K ... the Non-Surgical Alternative to LASIK (Laser Eye Surgery)

As seen on ABC's The View - Barbara Walters learns about Ortho-K (Corneal Refractive Therapy) from the NY Yankees team doctor.

Imagine being free from glasses or contact lenses all day long without the need for any kind of surgery.  Open your eyes - because imagination is now reality with Ortho-K ... the benefits of LASIK at a fraction of the cost.

It's hard to imagine waking up in the morning and not having to wear glasses or contact lenses during the day!  It would free you up for a host of activities that you may otherwise avoid because of your need to wear glasses or contact lenses.  And unlike surgery, Ortho-K is great for kids as well as adults.

A recently FDA approved, revolutionary non-surgical vision correction that improves your natural vision in a matter of hours without drugs or surgery is called Orthokeratology, or Ortho-K (also known as Corneal Refractive Therapy). Your nearsightedness and astigmatism may improve dramatically the day after your first fitting with the new Ortho-K therapy. Excellent vision is achieved in a unique way, with the wearing of specially designed vision retainers. These vision retainers, which resemble rigid oxygen-permeable contact lenses, are custom designed to gently change the shape of your cornea ( the front curvature of your eye) to safely and quickly improve your vision. The best analogy for Ortho-K is "orthodontics for the eye". The corneal shape is altered by gentle pressure from custom-designed vision retainers that work much like dental retainers.

This new method of vision improvement is accomplished most often over a period of days or several weeks to attain better vision. Ortho-K is safe, effective, and best of all, non-surgical and reversible.

Nearsightedness (Myopia)

Normal eyesight is present when light rays focus on the retina, creating a clear image. Nearsightedness, or myopia, occurs when the curvature of the cornea is too steep and/or the length of the eye is too long. As light rays pass through the steeper central cornea, they are refracted too much and come to a point of focus in front of the retina. This creates a blurred image on the retina. People with myopia experience blurred vision at longer distances, but may see well close up.

The curvature of the cornea and the axial length of the eyeball are responsible for myopia. With Ortho-K, contact lenses are used to reduce the corneal curvature and reduce the myopia, which improves unaided vision.


Many patients with myopia have some degree of astigmatism. This means that the cornea, rather than being completely round in shape, similar to a ball, may be slightly oval and shaped more like a football. People with astigmatism experience blurred vision and sometimes distortion or tilting of images due to unequal bending of the rays of light entering their eyes.

In astigmatism, light entering the eye focuses in multiple areas rather than in one location. High degrees of astigmatism will cause blurred vision for both far and near objects. For example, the image observed on the backside of a spoon is quite distorted and demonstrates a very high degree of astigmatism. Astigmatism often causes eyestrain and headaches, as well as blurred vision.

Ortho-K Vision Correction for Treatment of Nearsightedness and Astigmatism with Vision Retainers 

Before Ortho-K Vision Retainers are applied to your eyes, the curvature of your cornea is measured. Once the initial lens is designed, you will be instructed in the care and handling of the retainers, which are much like rigid contact lenses. You will be given exact wearing instructions, which typically involves wearing the lenses overnight only. Generally, you will be seen the day after lenses are dispensed. At that visit, the corneal health, vision, and corneal shape will be evaluated. Careful monitoring continues throughout the therapy.

Many patients ask, "How can specially designed and customized vision retainers possibly improve my vision without surgery?" As mentioned, due to the precise design of the vision retainers, the central curvature of the front of the eye is gently molded without removal of corneal tissue.

The vision retainers are worn at night and the new corneal shape is retained during the day. This method of reshaping reduces the light refracting power of the cornea and reduces or eliminates nearsightedness and astigmatism.

The high-tech, therapeutic vision retainers are manufactured using carefully constructed lathes to create the rigid oxygen-permeable material that allows enough oxygen to pass through the vision retainer and allows the eye to remain healthy, even during sleep.  Current Ortho-K vision retainers are made of highly oxygen-permeable materials which are FDA approved for overnight wear, allowing people to sleep with the vision retainers over their cornea.

Most of the visual changes that occur rapidly with Ortho-K happen in the first few days and most patients achieve significant results in the first week. Once maximum results are attained, retainer wear is initiated.

After treatment and maximum desired results are accomplished, retainer contact lenses (like retainers for the teeth) are worn as necessary to stabilize the results. That is, we determine the minimum wear necessary to maintain the correction change.  If retainer wear is discontinued, the cornea will simply return to its original shape within a few weeks. Failure to wear the retainer lens on an ongoing basis will result in the return to the pre-existing prescription. 


  • After correction, vision is improved without the help of glasses or contact lens wear during the day.
  • Vision improvement occurs rapidly -- in days or weeks.
  • Free from surgical risk, the Ortho-K process is convenient, comfortable and reversible.
  • With no age restrictions, Ortho-K is the perfect option for active kids and teens that aren't eligible for LASIK.
  • The natural vision achieved with Ortho-K is invaluable for recreation, sports and leisure.
  • Occupational demands for unaided vision may now be met by pilots, policemen, firemen, swimmers, and others.
  • Ortho-K is safe, rapid, and effective.
  • The cost of Ortho-K is approximately 1/4 the cost of LASIK.

Are You a Candidate for Orthokeratology?

In general, the ideal candidate for Ortho-K has nearsightedness that does not exceed 6.00 diopters and/or astigmatism greater than 1.50 diopters. Candidates must have healthy corneas and people with certain medical conditions or women who are pregnant may not be good candidates for Orthokeratology.
