© Davis Eye Associates 2014 Made with Xara Frequently Asked Questions What is Orthokeratology (Ortho-K) Ortho-K is the use of therapeutic corneal molds or lenses to gently reshape the curvature of the cornea (front part of the eye) to reduce nearsightedness, farsightedness and astigmatism.  How does Ortho-K work? Orthokeratology or Ortho-K is accomplished through the use of specially designed corneal molds or lenses.  These molds are worn while you sleep, and cause the migration of corneal cells to the peripheral cornea, thereby allowing you to see clearly throughout the day.  Watch this demo from the Ortho-K NETwork to see exactly how it works. What is involved with Orthokeratology? Each patient is required to have a comprehensive eye health examination.  If your prescription falls within a certain range, further testing will be done.  An extensive computerized corneal mapping (Corneal Topography) will help determine if you are a good candidate for this procedure. We will then design customized molding contact lenses using a CAD/CAM (Computer Assisted Design/ Computer Assisted Manufacturing) process and then a CNC lathe produces the lenses within 0.1 micron accuracy.  These molding lenses will be dispensed to you and you are trained in lens handling and care.  The lenses are worn only while you sleep.  Each night these lenses will gradually flatten your cornea, thereby improving your vision.  Typically within a week you will have clear vision that lasts all your waking hours. Is Orthokeratology an alternative to refractive surgery? Yes- Ortho-K is a non-surgical alternative to surgery.  Individuals interested in reducing their nearsightedness and astigmatism, but are apprehensive about surgery, now have a safe and effective alternative. We often receive referrals from area refractive surgeons asking us to assist them with patients that are not good surgery candidates, but might benefit from Ortho-K. Is Orthokeratology new? No- the concept and process of corneal molding has been available since 1962.  What is new is the Ortho-K design and computerized corneal mapping.  Ortho-K contact lenses customized to the patient's unique corneal shape using a CAD/CAM (Computer Assisted Design/ Computer Assisted Manufacturing) process and then CNC lathe production with 0.1 micron accuracy is new.  Dr. Lisa Davis has been monitoring the development of these advancements and has completed extensive training to ensure our patients' success. Is Orthokeratology permanent? No, unlike refractive surgery, Ortho-K is reversible simply by not wearing your molding contact lenses.  Within 1 to 7 days your vision will return to its pretreatment state. I suffer from “dry”eyes, could I benefit from Ortho-K? Yes. Many patients with slightly dry eyes do well with Ortho-K.  Since you are wearing the lenses only while sleeping, the closed eye state minimizes evaporation loss of tears and can give dry-eye patients improved vision without compromising the ocular surface.  Many dry eye patients are more comfortable during their waking hours with Ortho-K versus soft or gas permeable contact lenses.  Only your eye care professional can determine if you are an Ortho-K candidate. I used to wear contact lenses but stopped because of discomfort.  Am I a candidate for Orthokeratology? Ortho-K lenses are worn at night while you are sleeping. This greatly reduces any discomfort normally experienced while wearing contact lenses during the day. Can I see with my Ortho-K lenses in? Yes.  One of the great features of the Ortho-K lens is that if you get up in the middle of the night, you will be able to see perfectly.  You will enjoy great vision with your Ortho-K lenses on or off. What do I wear during the adaptation period? Your doctor will either have you wear your glasses or give you other diagnostic lenses to wear while your eyes are adapting to your new vision with the Ortho-K lenses. This is usually a short term situation of a week or so. Is there any scarring with Ortho-K? No- this process is a non-surgical vision correction. Is there any scarring with refractive surgery? Almost all refractive surgeries cause some minimal corneal scarring. How often do I have to wear the retainer (molding) contact lenses following Orthokeratology? This varies with each individual.  Some patients have to wear the lens each night while others only need to wear the lens every other night. Will medical insurance cover Orthokeratology or refractive surgery? No - even though Ortho-K improves your visual function, the insurance carrier defines all refractive surgeries and Ortho-K as cosmetic procedures. Does Ortho-K help stop my child’s eyes from getting worse? Rigid gas permeable lenses, the same used with Ortho-K, have been shown to slow the rate of progression of near-sightedness when compared to children wearing eyeglasses. More studies are needed to confirm this and the exact mechanism, but in our opinion children with rapidly progressing nearsightedness should wear these lenses in an attempt to reduce myopia progression. To learn more about how Ortho-k slows nearsightedness in children, please read the attached study. How old do I have to be to qualify for Ortho-K? This procedure is beneficial to any nearsighted or astigmatic patient within certain criteria. Age is not a restriction with Ortho-K, whereas in refractive surgery a patient must be at least 18 years of age.  Our youngest patient using Ortho-K is 7 years old and our eldest is 67. What are the fees for Orthokeratology and what does it include? The Ortho-K program includes corneal evaluation for 6 months, computer mapping of the corneas, the doctor's time and expertise to customize a pair of Ortho-K lenses, lens insertion and removal training, initial cleaning solutions and one pair of Ortho-K lenses.  Ask our doctor or staff for a range of applicable fees.  "CareCredit" offers an easy payment plan that can reduce your monthly payments to between $30 to $70 per month.
