Ophthalmologists use advanced laser system to improve vision


Patients who want their vision problems corrected with the latest laser technology can get their wish fulfilled by ophthalmologists at University of Iowa Hospitals and Clinics.

A highly advanced new system integrates a unique function that essentially generates a fingerprint of the eye with 3-D tracking capabilities and a treatment zone that is up to 51 percent larger than earlier systems.

"The system is precise, safe, and flexible," said John Sutphin, M.D., a clinical professor in the Department of Ophthalmology and Visual Sciences and a specialist in refractive corneal surgery. "We can treat patients even faster, yet the system is also very reliable and provides excellent outcomes."

The system, manufactured by VISX, Inc., is used by to treat patients who are near-sighted or far-sighted. The system provides photo-therapeutic keratectomy (PTK) and trans-epithelial (PRK) and subepithelial (LASEK) refractive surgery treatments, in addition to the more popular LASIK procedures.

It is the only laser eye surgery system that can capture all three dimensions of eye movements during a procedure, which means that it is not necessary to dilate the patient's eyes.

"We can also use the technology to adjust the size of the laser beam according to the treatment, which minimizes the amount of corneal tissue that is removed," Sutphin added. "In addition, we now screen patients with advanced new technology, to decide when waiting for the next type of laser treatment or not having laser treatment is in the patient's best interest."

Candidates for refractive surgery:

  • Age 18 years or older
  • Myopia (nearsightedness) up to -14 diopters either without astigmatism or from -0.5 to -5 diopters of astigmatism. INTACS are available for patients with myopia of -1 to -3 diopters and less than 1 diopter of astigmatism.
  • Hyperopia (farsightedness) from +1 to +6.0 diopters with less than 6 diopters of astigmatism by laser treatment, and +.75 to +3.00 with less than 1 diopter of astigmatism by Conductive Keratoplasty
  • No history of eye disease, corneal scarring, or retinal problems
  • Not pregnant or nursing for 3 months and not planning a pregnancy in the 6 months after surgery
  • A stable refraction
