Common Questions

What is laser vision correction?

Laser vision correction is an outpatient procedure that helps restore natural vision and reduces dependency on glasses and contact lenses. The laser works by using a cool beam of light to gently sculpt the surface of the eye known as 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. Dr. Kraff uses the Johnson & Johnson VISX Star S4 IR Laser system to help deliver amazing results! This laser is FDA-approved, which means the technology has undergone rigorous testing to determine safety and effectiveness.

How long have you been performing a laser vision correction surgery?

Dr. Colman Kraff is a pioneer in the field of laser vision correction. He has been doing laser vision correction in Chicago since 1991, when he was 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. Dr. Kraff offers the kind of knowledge and experience that you can trust with your eyes. He continues to pioneer and participate in the FDA clinical trials of new laser vision technology.

How many procedures have you performed in your Chicago LASIK offices?

Dr. Colman Kraff has performed over 70,000 laser procedures with the state-of-the-art VISX laser since 1991, making him the most experienced doctor in the Midwest. Dr. Kraff continues to operate with the highest levels of precision, safety, and patient satisfaction.

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

Dr. Kraff will be involved with your eye care every step of the way. We do offer patients the option of working with some of our affiliated optometrists throughout the Chicagoland area if that is more convenient for them. We also have optometrists in Indiana and Wisconsin that we arrange for you to work with. If a patient chooses to comanage with one of our outside doctors, that doctor will send your exam to Dr. Kraff for review.

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, Dr. Kraff will first create a flap on the cornea using the IntraLase Femtosecond Laser. Once created, Dr. Kraff will then lift the flap and use the VISX Excimer Laser to re-shape the cornea. After the laser treatment, Dr. Kraff will re-align the flap, putting it back in the same position it was prior to surgery. The flap will work like a natural band-aid to help expedite the healing process. Dr. Colman Kraff has performed over 70,000 laser vision correction procedures since 1991. When here for your initial consultation, Dr. Kraff will determine which technique is the safest for you.

What type of LASIK technology do you offer?

Dr. Kraff places an emphasis on providing patients the safest and most effective treatments available. Here at the Kraff Eye Institute we utilize the iDesign technology. The iDesign is the most advanced way of screening and mapping the cornea. This software gives Dr. Kraff the ability to truly customize each individual treatment. This technology is used in both LASIK and PRK treatments.

Is laser vision correction safe?

Over 10 million people worldwide have had laser eye surgery to help lessen their dependency on glasses and contact lenses. Laser eye surgery is a safe and effective treatment for those patients who fall within treatable perimeters. Based off measurements done pre-operatively, Dr. Kraff will determine if LASER eye surgery is a safe procedure for you.

Does laser vision correction hurt?

No, the treatment itself is painless. Topical anesthesia (eye drops) are applied throughout the procedure to help minimize discomfort. It is very normal post-operatively to experience some discomfort, but pain medication will be prescribed to help minimize those sensations.

How well will I see after laser vision correction?

Results vary with each individual. Most patients can expect vision similar to what they have with their glasses or contact lenses. With LASIK, most patients have a highly functioning vision by the day after surgery. Although it is not your final vision, a patient can resume most of their normal activities within 24 hours from their surgery. With PRK, the recovery process is slightly longer and a patient should plan accordingly so that their schedules allow for downtime.

Will I still need reading glasses after LASIK?

Laser eye surgery does not stop the natural aging process of the eye (presbyopia). Patients who are being treated for Myopia or Hyperopia should understand that they will still need reading glasses when they are in their late 40s or early 50s. If a patient is currently wearing reading glasses, then Dr. Kraff may recommend what is known as Monovision. Monovision will be discussed when you are in the office for your consultation.

How soon can I return to work?

With LASIK patients, most can resume their normal activities, including going back to work, by the day after their procedure. With PRK, where the recovery process is slightly longer, patients should plan on taking a couple days off of work.

What are the risks?

There are risks with any medical procedure. Dr. Kraff will discuss, in great detail, the risk factors with each patient when they are here for their initial consultation. If pre-operative measurements show any signs that a patient is not a good candidate for surgery, Dr. Kraff will let you know that you should not move forward.

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. At this appointment, we will examine your eyes to determine if you are a candidate and answer all your questions before you make this very personal and important decision. In addition to meeting with one of our Refractive Counselors, you will meet with Dr. Kraff 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.
