NearVision CK (Conductive Keratoplasty(R)) is a quick procedure with no cutting involved. You don't even have to go to an outpatient surgery center. In just three minutes, a doctor can perform NearVision CK in his or her office.
The procedure...
Using radiofrequency (RF) energy, NearVision CK can change how the eye focuses light by reshaping the cornea to make it steeper. After the doctor has applied a topical anesthetic (eye drops), controlled RF energy is applied in a circular pattern to shrink the corneal tissue. This pattern is applied in the periphery of your cornea and therefore minimizes interference with your line of sight (i.e., pupil). A device called a "speculum" holds your eye open during the procedure.
Once finished, you don't have to wear a patch and can usually return to work or normal activities the next day. 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.
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.
Risks and complications
NearVision CK is associated with a nominal amount of surgery-related complications. Some people who have had CK 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:
Discomfort and/or foreign body sensation
Glare
Halos
Overcorrection
Tearing |
