One to One LASIK is proud to introduce the latest advance
in the treatment of age-related loss of reading vision – a
procedure called “NearVision CK” or Conductive Keratoplasty
(CK). Conductive keratoplasty uses painless radio waves
to change the shape of the cornea, the clear front window
of the eye. For suitable candidates, this procedure can
reduce dependence on glasses for reading after age 40.
The normal age-related loss of close-up focusing power
after age of 40 is called “presbyopia.” Conductive Keratoplasty
(CK) can also be used to reduce dependence on glasses for
those 40 years and older who have mild to moderate amounts
of farsightedness.

| Conductive Keratoplasty (CK) for farsightedness
and NearVision CK to reduce the need for reading glasses
after age 40, make use of radio waves that are delivered,
painlessly, to the cornea (clear front window of the eye) in a ring-shaped pattern. The
radio waves cause heating and shrinking of the cornea, changing the shape
of the cornea. This changes the cornea's focussing power and helps to reduce
or eliminate the need for glasses. |
Conductive Keratoplasty (CK) uses a pen-shaped instrument with a cool tip as
thin as a human hair. After application of anesthetic eye drops, Dr. Feldman
applies radiofrequency (RF) energy to the cornea in a series of “spots” which
form a circular pattern. This pattern is applied in the outer edges of the
cornea and therefore minimizes interference with your line of sight. A device
called a "speculum" is inserted to hold your eye open during the
procedure, so you don't need to worry about blinking.
During the procedure, there is virtually no sensation at all. Once finished,
you don't have to wear a patch and can usually return to work the next day.
During the first 24 to 48 hours after the procedure, you may experience some
mild discomfort, including a foreign-object sensation or "scratchiness" in
the eye. Vision begins improving in about a week's time.
NearVision CK modifies the topographical (surface) curvature of the cornea,
making it temporarily steeper and improving near vision. In FDA clinical studies,
98% of patients were able to read newspaper-size print without reading glasses
after the CK procedure (12-month follow-up data). |
