Orthokeratology Shaping Lens

Defined - Orthokeratology is the temporary reduction of myopia achieved by the programmed application of contact lenses to reshape the cornea.

If you’re nearsighted, you’ve had to grow dependent upon eyeglasses or contact lenses for vision correction. At times it can be inconvenient. You may have even considered laser surgery, but been turned off by the risks. Now, there’s a non-surgical alternative that improves your vision while you sleep. It’s called Boston XO overnight Orthokeratology lens.

Vision Shaping Therapy (VST) also known as Orthokeratology (ortho-k) uses a special contact lens to gently reshape your cornea while you sleep. The reshaping of the cornea allows light entering the eye to focus on the retina correctly. When you wake up, you have better vision with your naked eye. You’ll be able to see clearly, without glasses or contact lenses. It works a lot like a dental retainer worn at night to help straighten teeth. The lenses work while you sleep. After a few weeks after VST you will begin to see clearer without the use of contacts, eyeglasses or surgery.

Ortho – k actually isn’t a new practice; in fact some eye care professionals have been using this method of correction for decades. Newer evolving technology has only made the process better, exhibiting more comfort, and longer lasting results.

The blue area in the above photo shows how the cornea was flattened to produce power. Unlike Laser or Lasik surgery this procedure is completely reversible.

Overnight Ortho – k lenses can be worn by just about anyone, of any age with nearsightedness (myopia) or a moderate amount of astigmatism. Modern advances in oxygen permeability make overnight wearing of contact lenses safer than ever.

Modern Orthokeratology achieves this using specially designed reverse geometry gas permeable (GP) ortho-k shaping lenses worn during sleep. This overnight wearing process provides a faster, more predictable result than early ortho-k attempts as practiced in the 1980s using conventional, rigid contact lenses fitted incrementally flatter. Using this vision shaping technique, properly selected patients can go through the day wearing no correction and enjoy excellent visual acuity.
