CHICAGO, Sept. 11 /PRNewswire/ -- Chicago residents who may be candidates
for laser eye surgery now have access to the latest development in Laser
Vision Correction technology, as the Rush Eye Laser Center is now using the
first of its kind, wavefront-guided LADARVision(R) excimer laser system to
perform laser eye surgery.
The U.S. Food & Drug Administration approved this system as the first of
its kind for performing wavefront guided laser eye surgery. With this new
system, made up of the LADARVision(R) 4000 Excimer laser and the LADARWave(TM)
wavefront measuring system, Rush Eye Laser Center ophthalmologists can, for
the first time, measure and treat visual disorders that previously could not
even be detected.
Several types of imperfections, referred to as lower- and higher-order
aberrations, exist within the eye and can affect both a person's visual acuity
and the quality of vision. To date, only lower-order aberrations, which
include nearsightedness, farsightedness and astigmatism, could be measured and
treated. However, lower-order aberrations do not account for all potential
vision disorders. Higher-order aberrations can also have a significant impact
on a person's quality of vision, and cannot be corrected with glasses,
contacts or conventional laser eye surgery. "Higher-order aberrations are
linked to visual disturbances such as glare and halos that may cause night
vision problems and are sometimes associated with conventional laser eye
surgery," said Jonathan Rubenstein, M.D., Director of Refractive Surgery at
Rush.
"By using advanced technology to measure both lower- and higher-order
aberrations, and then treating each patient's unique pattern of lower- and
higher-order visual errors, we are aiming to improve both visual acuity, which
is measured against standard numerical outcomes such as 20/20, and the overall
quality of vision, such as increased visual crispness and clarity," said
Thomas Deutsch, M.D., Chairman, Department of Ophthalmology. Visual acuity of
20/20, considered by most as the standard for vision, has been traditionally
measured by a letter chart, which does not provide for detection of many of
the disorders that may affect vision.
"Sometimes patients complain about vision quality problems, such as not
being able to see in dim or low light. This is referred to as poor contrast
sensitivity," explains Dr. Rubenstein. "Prior to the advent of wavefront
measurements, there wasn't anything we could do to measure or treat
higher-order aberrations. With this technology breakthrough, we can now
measure these disorders, show the patient what's going on in their eye, link
that information to the laser, and actually correct higher-order aberrations
that diminish contrast sensitivity. Wavefront technology enables the surgeon
to improve overall vision quality better than in the past."
