Conductive Keratoplasty

Conductive Keratoplasty SM (CK) is the only FDA-approved procedure for mild to moderate hyperopia that uses radiofrequency instead of a laser.

CK builds upon the principles of thermokeratoplasty, using radiofrequency (RF) energy to reshape the cornea and therefore adjust its refractive characteristics.

What happens during the procedure?
After applying drops to numb the eye, the doctor imprints a treatment pattern on the cornea using rinse-away dye. The doctor will have determined the pattern in advance of the procedure, based on the individual patient’s amount of hyperopia and details of their examination. The pattern guides the doctor’s treatment; each point represents a place where radiofrequency (RF) energy will be applied. Once the cornea is marked, the doctor uses a small probe to apply the energy in a circular pattern to reshape the cornea

Is CK painful?
The CK procedure is considered painless. The most common sensation that patients experience is a feeling of pressure on the eye. Patients may also be aware of a support or speculum that helps to hold the eye open. After surgery, there may be some mild discomfort, and many patients experience a foreign-object sensation or "scratchiness" in the eye. This usually subsides within 24 hours of the procedure.

After CK?
Most patients report an immediate improvement within the first day. For others, the improvement may not be apparent for the first few weeks. It usually takes a few weeks for the eye to adjust to the final level of treatment.

Who is a good candidate for CK?
To be eligible for CK, the eye must be in good health and vision must be stable. However, some people are better candidates than others and consultation with the doctor prior to surgery is important to determine estimated benefits and possible complications.

NearVision Conductive Keratoplasty

Are you having trouble reading up close?
It seems to happen overnight. You suddenly can’t read a menu, see your alarm clock or review the scores on your golf card. But you’re not alone. Millions of baby boomers like you are losing their near vision as part of the natural aging process.

Why vision loss with age?
When we turn 40, our eyes begin losing their ability to easily focus on near objects. This can be the result of two different conditions.

  • Farsightedness (hyperopia): When the surface of the eye (cornea) is too flat, changing the way our eyes focus light. Young eyes are often strong enough to compensate, which is why it may only be a problem after 40.
  • Presbyopia: When the lens in the eye loses flexibility because of age. This also causes problems in the way our eyes focus light. Everybody over age 45 will eventually suffer from this condition.

Over 100,000 people have improved their near vision.
NearVision CK can help improve your vision, allowing you to see clearly like you could 10 years ago. It’s an exciting new advancement in vision correction because it uses radio waves instead of a laser to treat your vision problem.

  • No cutting – helps minimize side effects and speed recovery.
  • Convenient and safe – your doctor performs the procedure in his or her office.
  • Fast and easy – takes only 3 to 5 minutes and is virtually painless.

How NearVision CK works
NearVision CK can change how the eye focuses light by reshaping the surface of your eye (cornea). When the shape is changed, light can be refocused on the correct part of your eye (retina). To produce this reshaping, NearVision CK uses the controlled release of radio waves to heat and shrink corneal tissue. This steepens the cornea and allows light to properly focus on the retina again.

What to expect during a NearVision CK procedure.
Once your doctor has determined that you are a candidate for NearVision CK, your eye will be photographed to determine its current and individual shape. This will be used to plan the procedure and measure results.

What to expect before and after a NearVision CK procedure.
Before the procedure, the only requirements are to not wear makeup and arrange for transportation to and from your doctor’s office. The procedure itself is fast and simple and will take just a few minutes to perform.

After the procedure, and as with other vision correction procedures, you may experience some eye discomfort and light sensitivity for a few days. Your doctor will recommend that you apply eye drops for a few days after the procedure. Ask your doctor or ophthalmic technician for more information.

Are you a candidate for NearVision CK?

  • Are you over 45 years of age?
  • Have you had great distance vision without glasses for most of your life?
  • Are you tired of your reading glasses?

If you answered yes to these three questions, you may be a candidate for NearVision CK.

You may NOT be a good candidate for NearVision CK if:

  • You have had significant changes in your vision over the past year.
  • You have any chronic eye disorders.
  • You are pregnant or nursing.
  • You have a chronic illness or disease.

Take the next step toward freedom from reading glasses.

NearVision CK improves your ability to focus on near objects without reading glasses. In the clinical study for NearVision CK, 9 out of 10 patients could see 20/20 or better in the distance and could read newspaper-sized print after the procedure without glasses.

If you are interested in the NearVision CK procedure, talk to your doctor and get a full eye examination. He or she will determine your specific vision needs and treatment plan and establish if NearVision CK is the right procedure for you.
