Conductive Keratoplasty is a relatively new procedure that uses radio waves to shrink collagen tissue within the cornea to treat low to moderate farsightedness and presbyopia and bring near vision back in focus.
Using a small probe, thinner than a strand of human hair, a controlled release of radio waves are applied in a circular pattern on the outer cornea to shrink small areas of collagen. This creates a restrictive band, like the tightening of a belt, that increases the curvature of the cornea.
NearVision CK is for those who:
- want to reduce or eliminate their dependence on glasses, reading glasses or contacts
- have difficulty with close vision
- are at least 40 years of age
- have not had a significant change in their vision for one year
- have no health issues affecting their eyes
- have not had previous vision correction surgery
- are not pregnant or nursing
What to expect on the day of your procedure
NearVision CK does not require a surgical facility. First, your eye will be completely numbed with powerful eye drop anesthesia. When your eye is completely numb, an eyelid holder will be placed between your eyelids to keep you from blinking during the procedure.
Then either sitting upright as if undergoing an eye exam or lying back, you’ll be asked to look at the microscope light. Your eye will be marked with a series of dots. Your surgeon will touch the dots with the probe making a full circle around the outer margins of the cornea. There will be eight to 32 treatment points, depending on the amount of correction needed. As the dots are touched, heat from the radio waves shrinks the tissue, producing a clenching effect that creates a more curved cornea. Some patients elect to have only one eye treated to give them monovision.
Soon after the procedure, your eyes will be examined and you will go home and relax for the rest of the day. For the first couple of days, you may experience some scratchiness in your eyes, or excessive watering. This rapidly improves and medications can be taken to relieve any discomfort. Normal activities are generally resumed within a day or two. While many patients see improvement in their near vision immediately after the procedure, it usually takes a few weeks to several months for vision to stabalize and the results to be fully realized. As with other vision correction procedures, you may experience some discomfort and light sensitivity (glare or halos) for a few days following NearVision CK.
The decision to have NearVision CK is an important one that only you can make. The goal of any refractive surgical procedure is to reduce your dependence on corrective lenses. However, we cannot guarantee you will have the results you desire.
Because NearVision CK is minimally invasive, the procedure has exhibited very minimal risk and almost no side effects. During the first 24 to 48 hours after NearVision CK, you may experience tearing and some discomfort. You may also experience slight over-correction of your vision, which stabalizes during the following weeks. If you are a good candidate, you will be given additional information about the procedure that will allow you to make an informed decision about whether to proceed. Be sure you have all your questions answered to your satisfaction.
