Can you read this? How about this? Close
up vision often erodes with age, but most baby boomers would rather
fumble with reading glasses than rush for eye surgery. The otherwise
popular LASIK uses lasers to cut and reshape the cornea, and in rare
cases it can cause scaring or infection. People of a certain age,
it seems, don’t like their eyes sliced. Now Conductive
Keratoplasty—a new three-minute, outpatient, slice-free
technique—helps safely restore close vision in farsighted
folks and is recommended for those over age 40. Last week at the
annual meeting of the American Academy of Ophthalmology, researchers
announced that the procedure, abbreviated as CK, restored normal
vision in 93 percent of patients over the two years of study.

“This is really a baby boomer eye surgery,” says
Robert Maloney, a Los Angeles ophthalmologist and one of the 54
doctors who tested the treatment during Food and Drug Administration
trials. About 350 additional U.S. physicians will get training
in the technique by spring, according to Refractec Inc., the
company that makes the CK system.
Tiny adjustment, big change. Farsightedness is the result of an
eyeball that’s too short or a cornea that’s not
curved enough. Both lead to the improper focusing of light on
the retina, causing close objects to appear fuzzy. In CK, after
applying a numbing eyedrop, a doctor inserts tiny metal probes
around the cornea, going just 1/50th of an inch deep. Heat sent
through the probes cinches the corneal tissue, increasing
it’s curve.
Bill Halvorsen, 54, a retired police sergeant from Las Vegas,
says he “was tired of having glasses all over the
place.” Maloney performed CK, and a few minutes later asked
Halvorsen to read the time on his watch. “For the first
time ever I could read all the little writing on it.”
The key is what happens to people like Halvorsen even beyond two
years, says Mark Speaker, an ophthalmologist with the New York
Eye and Ear Infirmary who is gearing up to offer CK to his
patients. “It will take more time to really say that
the outcomes are as good as those with LASIK.” The best
candidates are those who were either born farsighted or developed
the condition with age, are age over 40, and whose eyeglass
prescriptions has changed little for at least 12 months. And
like LASIK, CK isn’t covered by insurance companies. So
the biggest discomfort might be the price—Maloney charges
$2,450 per eye. At least patients can sign their checks without
rooting around for glasses. |
