You're a candidate for NearVision CK if you:

Unlike LASIK, CK uses radiofrequency (RF) energy instead of a laser to change the shape of the cornea. The surgeon uses a small probe, thinner than a strand of human hair, to apply controlled RF energy to the edge of the cornea in a ring pattern. This circular pattern gently steepens the cornea to help improve the focusing on nearer objrcts. The procedure takes less than 5 minutes per eye and is painless.  Only topical anesthetic administered by eye drops is required to make the procedure  comfortable. CK does not require any cutting or removal of corneal tissue.  The energy is only applied only peripherally avoiding the central visual axis.

Most patients notice an immediate improvement in their reading vision after CK, like the ability to clearly see the face of their watch or to read a newspaper. However, it may take several weeks for the eyes to adjust to their final correction, resulting in fluctuating vision for a week or so.  You may also experience a temporary over-correction of your vision, causing your distance vision may be overly blurry. This will improve during the following weeks. Although the results from CK have shown long term stability,, your eyes will continue to age and you may need additional CK treatment at some point.

Blended Vision - The Best of Both Worlds

CK takes advantage of a technique called Blended Vision. Unlike monovision (where one eye is treated for near vision, leaving the untreated eye for distance vision), Blended Vision improves your ability to focus on near objects with dramatically less impact on distance vision in the treated eye compared with monovision. Data collected in FDA clinical trials on the CK Blended Vision procedure have shown relatively little effect on depth perception or the ability to distinguish contrast under day and night conditions. After the CK procedure:

If you have not been able to tolerate monovision in the past, Blended Vision may be a good choice for you.
