We Know: All About NearVision CK What is NearVision CK? NearVision Conductive Keratoplasty, or NearVision CK, is a non-invasive procedure that improves near vision. A tiny probe delivers radio waves in a circular pattern around the periphery of the cornea. This reshapes the cornea by shrinking the collagen tissue. The non-dominant eye is corrected for near vision while the dominant eye is corrected for distance vision, resulting in a phenomenon called "blended vision." The Food and Drug Administration (FDA) approved NearVision CK to correct mild to moderate presbyopia, a decline in near vision due to aging. This procedure is non-invasive, with milder complications than the more popular LASIK procedure. Who receives treatment by NearVision CK? Potential candidates for the procedure must be over the age of 40 with presbyopia or hyperopia. Presbyopia is the diminished capacity of the eye to focus on objects. Hyperopia is the opposite of presbyopia and affects distance vision. Both conditions occur with increasing age. Doctors do not recommended NearVision CK for those who have had previous corneal surgery and dry eyes. Can both eyes be treated with NearVision CK? NearVision CK is used for the non-dominant eye. The dominant eye is treated for distance vision. Both eyes may not be treated simultaneously. What is involved in NearVision CK? NearVision CK is performed in a medical office on an outpatient basis. The steps involved in NearVision CK include: The ophthalmologist applies eye drops to the eye to numb it. The ophthalmologist uses ink to imprint a circular pattern around the eye. A probe with a fine tip applies radio waves to the cornea in a circular pattern. Anywhere from 8 to 32 spots are placed around the corneal stoma. Collagen around the cornea shrinks, and the tightening bands of tissue steepen (curve) the cornea. How effective is NearVision CK? According to a one-year clinical study sponsored by Refractec, Inc. and approved by the FDA, 85% of the patients treated with NearVision CK had improved near vision, with 76% reporting satisfaction with the procedure. The FDA study concluded that NearVision CK is effective in re-creating near vision for age-related losses, but it does not restore near vision. What is the difference between LASIK and NearVision CK and why would I choose NearVision CK? The major difference between LASIK and NearVision CK is that NearVision CK is a non-invasive procedure. This means that there are no incisions or cutting into tissue. By using NearVision CK to correct near vision, patients avoid the typical side effects of LASIK which include: Creation of a flap in LASIK creates some risk in the structure of the cornea. LASIK causes dry eye which is a result of severed corneal nerves. NearVision CK is easier to perform, entails reduced costs, and does not involve cutting into any organ or tissue. Is NearVision CK covered by insurance? NearVision CK is not covered by insurance currently. What are the risks of NearVision CK? NearVision CK creates a phenomenon called "blended vision," caused by the changes made to the surface of the cornea.
