Using radiofrequency (RF) energy, NearVision CK can change how the eye focuses light by reshaping the cornea to make it steeper. After Dr. O'Brien has applied a topical anesthetic (eye drops), controlled RF energy is applied in a circular pattern on the outer part of the cornea using a hand-held instrument containing a probe smaller than a human hair. This pattern is applied in the periphery of your cornea and therefore minimizes interference with your line of sight (i.e., pupil). The low-level radiofrequency energy causes the connective tissue within the cornea to shrink, acting like a belt that tightens, increasing the curvature of the cornea. Changing the curvature of the cornea affects the way light rays enter the eye, thus bringing near vision back into focus. A medical instrument holds your eye open during the procedure.
Once finished, you don't have to wear a patch and can usually function normally again the next day. For at least one week after surgery, you should avoid swimming or other activities that may allow water to splash into your eyes. When showering, you're your eyes closed as much as possible and avoid spraying water into your face. Avoid wearing eye makeup for a week after the procedure, as well. Vision generally begins improving in about a week's time. As with other procedures, the level of improved vision may be temporary. While NearVision CK can turn back the clock on your vision, it cannot stop the clock entirely.
For those who have clear distance vision but have a difficult time seeing up close, NearVision CK can also be used to achieve monovision, or blended vision, when performed in only one eye. This type of refractive surgery procedure can improve close-up vision in a presbyopic eye with good vision but poor near focus. The non-dominant eye is set to near focus, while the other eye is left or set at good distance vision.
As may happen with any monovision correction treatment or a LASIK eye surgery procedure, your driving vision with this type of vision correction may be less sharp than it is when both eyes see distance clearly. While CK surgery can improve near vision, this type of refractive surgery does not cause as much blurring of distance vision as monovision with contact lenses or laser vision correction procedures. Your eye doctor may perform a quick monovision test which involves holding a lens for near vision correction in front or your eye to see how you might adapt to NearVision CK.
Here are some benefits of NearVision CK:
NearVision CK can also help patients with farsightedness, or hyperopia, a condition in which the eye is too flat. CK modifies the topographical (surface) curvature, making it steeper and therefore improving vision.
NearVision CK is associated with a nominal amount of surgery-related complications. Some people who have had CK refractive surgery have experienced side effects that have impaired their vision for a few days after the procedure. Although these risks are relatively rare, they should be taken into consideration by anyone considering the NearVision CK procedure.
Some side effects include:
If you are over the age of 40, your vision has been stable for about a year prior to having the procedure, and you do not suffer from dry eye or other eye diseases you may be a good candidate for NearVision CK. Should you have a pacemaker, you may not be eligible for this procedure due to the fact radiofrequency waves can interfere with the device.
