Conductive Keratoplasty (CK)
and
"NearVision CK" |
| |
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) 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). |

Conductive Keratoplasty (CK) for
farsightedness and NearVision CK
reduces the need for reading glasses after
age 40 and makes 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. |
