Frequently Asked Questions

What is laser vision correction?

Laser vision correction is an outpatient procedure that helps restore natural vision and reduces dependence upon glasses and contact lenses by using a cool beam of light to gently sculpt the surface of the eye—the cornea. The light gently pulses to remove a microscopic amount of tissue, changing the curvature of the cornea, allowing images to be more sharply focused on the retina.

The Kraff Eye Institute offers the most progressive technology in Refractive Surgery. Only state-of-the-art lasers and the safest, most advanced instruments for performing LASIK are utilized. The Kraff Eye Institute has a state-of-the-art AMO/VISX Star S4 IR Laser system at each facility. This laser is FDA-approved, which means the technology has undergone rigorous testing to determine safety and effectiveness.

How long have you been performing laser vision correction surgery?

The doctors at the Kraff Eye Institute are pioneers in the field of laser vision correction. They have been doing laser vision correction in Chicago since 1991, when they were selected as one of the ten investigational sites in the original FDA clinical trials that found laser vision correction as a safe and effective treatment for eligible patients. The doctors at the Kraff Eye Institute offer the kind of knowledge and experience that you can trust with your eyes. They continue to pioneer and participate in in FDA clinical trials of new laser vision technology.

How many procedures have you performed?

Our physicians at the Kraff Eye Institute have performed over 40,000 Lasik procedures with the state-of-the-art VISX laser since 1991, making them the most experienced doctors in the Midwest. Chicago LASIK doctors Manus Kraff and Colman Kraff continue to operate with the highest levels of precision, safety, and patient satisfaction.

Will the doctor be performing my pre-operative and follow-up examinations?

At the Kraff Eye Institute, your Chicago LASIK doctors will be involved from the initial consultation through all of your follow-up visits. We believe that every Chicago LASIK patient is unique and requires personal attention. We also work with a number of optometrists throughout Chicagoland, Northwest Indiana, and Wisconsin to offer the convenience of co-managed care to patients. The Kraff Eye Institute is committed to bringing you the best results that Laser Vision Correction surgery can offer.

Have you participated in research activities, lecturing, or writing?

Dr. Manus Kraff and Dr. Colman Kraff have been invited to lectures and teach at scientific institutions such as John Hopkins, Yale University, Hebrew University, in Jerusalem and Vanderbilt. They have chaired national ophthalmology programs, published numerous scientific papers upon research performed at the Institute, and The Kraff Eye Institute continues to pioneer in the field of Laser Vision and Correction.

What is the difference between PRK and LASIK?

PRK (Photorefractive Keratectomy) and LASIK (Laser in-situ Keratomileusis) both utilize the VISX Excimer Laser to remove corneal tissue in order to re-shape the cornea. In the PRK procedure, the laser works on the surface of the cornea. With LASIK, the surgeon first creates a flap on the cornea using either the IntraLase laser or the microkeratome and then uses the laser for treatment below the corneal surface. The doctors at the Kraff Eye Institute have performed over 40,000 laser vision correction procedures since 1991. The doctors at Kraff Eye Institute will determine which technique is the best for your eyes, and discuss your options with you.

What type of LASIK technology do you offer?

The Kraff Eye Institute has always placed an emphasis on providing the safest and most effective methods to perform LASIK surgery. In recent years, we have employed technological advances including Custom Wavefront™ LASIK and IntraLase® LASIK which have allowed them to treat even a greater percentage of patients. They will continue to evaluate each new technology and its advantages as it relates to LASIK safety and accuracy. For more information, please read our Chicago LASIK technology section.

Is laser vision correction safe?

Over seven million patients worldwide have had this treatment performed on them successfully. Our practice at the Kraff Eye Institute has been performing laser vision correction procedures since 1991, when we were selected as one of the ten investigational sites in the original FDA clinical trials that found laser vision correction a safe and effective treatment for eligible patients.

Does laser vision correction hurt?

No, the treatment itself is painless. Topical anesthesia (eye drops) are applied just before the procedure to eliminate any pain. Some patients may experience mild discomfort for one to three days after treatment. Many patients compare this to a sensation of sand in the eye.

How well will I see after laser vision correction?

Results vary with each individual. The large majority of people can expect vision similar to what they have with their glasses or contact lenses. In fact, 98% of our patients see well enough to pass a driver's test without corrective lenses. Vision may be slightly blurry in the days following the procedure and some patients experience small vision changes during the first several months, which is normal.

Will I still need reading glasses after LASIK?

If you used reading glasses before LASIK surgery, you may still need reading glasses after surgery. It is more than likely that you are suffering from presbyopia, an eye condition which is common with the aging process. For some patients who already require reading glasses, a monovision LASIK procedure may be an option. Monovision LASIK is a procedure in which one eye is left slightly nearsighted for reading, and the other eye is treated for distance vision. The doctors will cover this information with you during your LASIK consultation.

How soon can I return to work?

90% of LASIK patients return to their normal activities the day after their procedure, while PRK patients require a slightly longer recovery time. Two to three days of rest is suggested for patients who have PRK.

What are the risks?

There are risks with any medical procedure. The Kraff Eye Institute doctors will discuss in great detail the risk factors with each patient, and if a patient is a suitable candidate for the procedure based on their individual needs. The most common problem associated with laser vision correction is undercorrection or overcorrection. Fortunately these problems are usually not visually significant and can be treated. In a small percentage of patients, an enhancement may be required.

How do I know if I can have laser vision correction?

The best way to determine if you are a candidate is to schedule a no-cost consultation appointment in one of our Chicago LASIK offices. At this appointment, we will examine your eyes to determine if you are a candidate, and answer all of your questions before you make this very personal and important decision. In addition to meeting with one of our professional coordinators, you will meet with your surgeon to discuss your individual needs.

Do you have financing available? If so what are the terms?

Kraff Eye Institute offers financing through CareCredit, America's top patient payment program. CareCredit offers flexible monthly payment plans which help with the upfront costs of LASIK. To find out more about our financing options, visit our Chicago LASIK Financing page.
