            NEW LASER CORRECTS VISION WITHOUT INCISION

    DETROIT, Nov. 8 -- The Kresge Eye Institute of Wayne
State University, part of The Detroit Medical Center is testing a laser
that sculpts a corrective prescription on the cornea of the eye.
    The Kresge Eye Institute is one of five sites nationwide selected by
the U.S. Food and Drug Administration to study the most advanced
technology in the field of excimer laser in clinical tril.  he lasr
correctsdistotedvisin wit a high-intensity liht bem.
    For the first phase of the clinical trials, ophthalomologists at the
Kresge Eye Institute are seeking an initial 28 patients who are
dissatisfied with current eye glasses or contact lens visual correction
for nearsightedness, which may range from -1.00 to 10.00 diopters.  This
clinical trial is unique in that it allows correction of myopia up to -
10.00 diopters.
    "The excimer laser is a refined technique to reshape the front of
the eye, called the cornea, and will markedly reduce or eliminate
reliance on corrective lenses," says Jayne S. Weiss, M.D., Associate
Professor of Opthalmology at Kresge Eye Institute/Wayne State
University, and principal investigator of the study.
    The excimer laser does not require that incisions be made into the
cornea of the eye, unlike traditional Radial Keratotomy surgery.  Rather
than cutting, excimer laser shaves off preprogrammed outer layers of the
cornea's tissue, intended to preserve the internal eye structure.
    Patients for the first phase of the Kresge Eye Institute excimer
laser study will be those who have nearsightedness (myopia correctable
with eye glasses or contact lenses) which can range as high as -10.00
diopters, be at least 18 years of age, and have otherwise healthy eyes
with stable vision.
    After vision in the first eye is corrected, follow-up will be
conducted to ensure there are no complications and patients will then
have the option of undergoing vision correction in the other eye, if
appropriate, at a later date.
    The cost for undergoing the excimer laser procedure is approximately
$1,500 for each eye and includes follow-up care during the anticipated
three-year length of the study.  "The funds will pay for this very
advanced laser which costs just under a half a million dollars," says
Dr. Weiss.
    Duringthe irst hase f te study only corretion ofsimplemyopi
wil be studied but clinical potocls re eingdeveloped wich will
require further FDA approval to treat myopia with associated
astigmatism, simple hyperopia (farsightedness), hyperopia with
astigmatism, therapeutic treatment for corneal scars, and advanced
myopia (greater than 10 diopters).
    Other test sites for the Meditec laser study are located in
Minnesota, Florida, Kentucky and Texas.
    Mark L. McDermott, M.D., Associate Professor of Ophthamology at
Kresge Eye Institute/Wayne State University, will share responsibility
for the studies with Dr. Weiss.
    People who are interested in participating in the study but are not
sure they are in the category of myopia required for this study can
confirm their degree of myopia with their eye care professional.
    People interested in the Kresge Eye Institute trial should call
313-577-0145, or 810-573-9866, for more information.
    The Kresge Eye Institute, established in 1948, was the first
comprehensive eye treatment and research center in Michigan.  The Kresge
Eye Institute serves as the Department of Ophthalmology for the Wayne
State University School of Medicine and administers and directs all
ophthalmological services for The Detroit Medical Center.
