Orthokeratology

What Is Orthokeratology?

Ortho-K (short for Orthokeratology) is a non-surgical procedure using specially designed contact lenses to gently reshape the curvature of the eye to improve vision and slow the progression of myopia.

Orthokeratology is a revolutionary non-surgical procedure that eliminates the need for glasses or daytime contact lenses. It improves vision by gently reshaping your eye WHILE YOU SLEEP using specially designed therapeutic contact lenses. You just put the specially fitted lenses in at bedtime, and when you awake, you will have clear, sharp, natural vision for your waking hours.

This safe and effective treatment can correct near-sightedness (myopia) and more importantly can significantly slow down or even stop the progression of myopia in children. It is a great alternative to LASIK for those who don’t want the risk or are not ready for surgery.

In the most basic of terms, Accelerated Overnight Orthokeratology or Ortho-K is the science of changing the curvature or shape of the cornea to change how light is focused on the retina at the back of one’s eye.

Think of the cornea as the eye’s equivalent of a watch crystal. It is a clear, dome shaped structure that overlies the colored iris. Its tissue is most similar to clear, wet skin; and like skin it is very pliable. Because the cornea separates the eye from air and the rest of the outside world and because it has a curvature that bends light towards the back of the eye, it is responsible for most of the eye’s corrective power and contributes to various conditions such as nearsightedness (myopia), farsightedness (hyperopia), and the blur of astigmatism.

When you choose Ortho-k a few key tests must be performed. Chief among these tests is the determination that your eyes are healthy. Dr. Silverman will examine the retina and also the health of the outside of the eye. The other key procedure is the mapping of your cornea. To do this an instrument called a Topographer is used. Just like a topographical map of a camping area show hills, plains, and valleys; the topography of the eye shows Dr. Silverman exactly how your cornea is shaped.

The information from your corneal mapping plus the size of your cornea and the prescription needed to correct your vision are all used to design the Wave NightLens retainer lenses (corneal molds) needed to create the Ortho-k effect. The FDA approved Bausch + Lomb Vision Shaping Technology Wave NightLens is the most advanced Ortho-k lens design available and is custom designed to each unique cornea. Dr. Silverman has been designing and fitting Wave Ortho-k retainer lenses for over a decade.

On the day you pick up your Wave NightLens Ortho-k retainer lenses you will be instructed in how to insert, remove, and take care of your vision retainer lenses. The fit of your retainers will be evaluated and you will be scheduled to be seen after your first night of wear. On day 1, Dr. Silverman will re-evaluate your fit and newly corrected vision and another mapping of your cornea will be performed.

Throughout your initial fitting period, Dr. Silverman will monitor your corneal health and the effectiveness of treatment. Orthokeratology can produce results in a surprisingly short period of time.

We advise patients that they may need to use their retainers every night to maintain their newly corrected vision although some patients are able to vary their wearing time to once every two to four nights. The reason for this is due to the flexibility of your cornea
