ABBOTT PARK, Ill., Dec. 17, 2013 /PRNewswire/ -- With the introduction of
Abbott's iDesign Dx system, U.S. ophthalmologists now have a diagnostic tool
that can capture five optical measurements in one three-second scan to
determine the patient's visual abnormalities. This highly advanced diagnostic
tool measures the internal optics and surface of the eye more precisely than
conventional methods, allowing doctors to fully evaluate imperfections that
result in poor vision. Obtaining these measurements in one three-second scan
enables ophthalmologists to screen patients more efficiently to determine if
they are eligible for LASIK or other refractive surgery and to assist in
diagnosis of other conditions.

The iDesign Dx system uses advanced wavefront sensing technology to measure
and map "aberrated" eyes – i.e., eyes with visual irregularities. This same
technology, developed by Abbott scientists, was used by NASA to measure and
precisely shape the mirrors in the James Webb Space Telescope to ensure it
transmits high resolution images of deep space back to Earth after it launches
in 2018.

"The same technology used to measure optics in space telescopes has now been
applied to the eye with the iDesign Dx system, allowing us to take
microscopically-precise measurements of the eye with greatly increased
resolution," said Steven Schallhorn, M.D., clinical professor, University of
California San Francisco Department of Ophthalmology. "These higher-resolution
measurements provide details that improve our ability to measure ocular
aberrations with accuracy, precision and greater dynamic range."

The iDesign Dx system measures not only the optical system, but also
individual components of the eye. This means the iDesign Dx system can capture
the shape of the cornea; its curvature/power; the ocular wavefront; a
patient's refraction (how light passes through the eye); and pupil diameter
under different lighting conditions − all in one scan of the eye.

How Wavefront Sensing Technology Works

The wavefront sensor measures all aspects of light: its intensity or
brightness, as well as the light ray angles on the eye. By sending a beam of
light into a patient's optical system and measuring the quantity and quality
of light that bounces back, the wavefront sensor provides important data on
the performance of the system, as well as where improvement is needed.

"The iDesign Dx system, at its core, is the next generation of wavefront
technology – most significantly, the improved degree of resolution that can
now be captured," said Dr. Schallhorn. "Passing through the optics of the eye,
the wavefront technology projects a small spot of light on the retina. That
light scatters from the retina and is collected by the lens in the eye through
the cornea and then travels back into the instrument."

The iDesign Dx system's wavefront sensor is made from a tiny micro lens array
comprising thousands of lenslets, each the diameter of a human hair. This lens
array increases the resolution of the wavefront scan five-fold. With this
data, ophthalmologists can see increased details of the cornea and the optical


The iDesign Dx system launched in 2013 in the United States for diagnostic
use. In Europe and a number of countries around the world, including
Australia, Brazil, Canada, India, Japan, and New Zealand, the iDesign Advanced
WaveScan Studio is currently approved for LASIK treatment, planning, screening
and diagnostics. The iDesign Advanced WaveScan Studio is not approved in the
United States.
