iLASIK Milwaukee Wisconsin

Dr. Steven B. Koenig, iLASIK surgeon at The Eye Institute in Milwaukee, Wisconsin has helped thousands of individuals realize the life-changing effects of vision correction surgery offering The IntraLase Method™, CustomVue™, and Photorefractive Keratectomy (PRK).  Watch the video shown below to learn more about the vision-enhancing procedures we offer.  For more information contact The Eye Institute at (414) 955-2020.

The IntraLase Method™ ( of iLASIK surgery ) BLADE-FREE METHOD OF iLASIK SURGERY

The first step of iLASIK surgery is to create the corneal flap using BLADE-FREE technology. The IntraLase Method™ uses an infrared laser to create the flap from below the surface of the cornea.


  • Improved Safety - Virtually eliminates the most severe iLASIK complications
  • Fewer Re-treatments -The number of enhancements required to perfect the visual outcome is significantly lower.
  • Reduced Dry Eye Symptoms- In clinical studies, standard tests performed to diagnose dry eye show a reduction in symptoms by as much as 72 percent.
  • Thinner Flaps- Patients with thin corneas may now be candidates for iLASIK.

IntraLase Flap Description

The following steps describe a typical iLASIK procedure.

Tiny pulses of light pass harmlessly through the outer portion of your cornea and form a uniform layer of microscopic bubbles just beneath the surface of your eye.

These bubbles define the flap’s dimensions and distinct beveled edge, as well as the location of the hinge. This entire process is computer controlled for maximum precision.

Dr. Koenig then separates the tissue where these bubbles occur, folding it back to complete the flap.

Step 2 -  Cornea is Reshaped

The AMO STAR S4™ Excimer Laser System is used to reshape the cornea by removing microscopic amounts of tissue.  It produces an extremely smooth treatment surface on the cornea. Smoother treatments promote faster healing and result in better visual outcomes.

Step 3 - Flap is Replaced

When the treatment is complete, the flap is put back in place, a process made more accurate by the unique beveled edge created by the IntraLase FS60™ Laser.

PRK (Photorefractive Keratectomy)

Dr. Koenig offers an alternative to iLASIK, known as Photorefractive Keratectomy (PRK). This procedure is usually chosen if your corneas are too thin, too steep, or too flat to proceed with conventional iLASIK.

The main difference between iLASIK and PRK is that while iLASIK involves a flap, allowing the correction to be made to the inner layer of the cornea, PRK does not involve a flap and the correction is made to the surface of the cornea.

After the procedure, patients wear a protective contact lens for one week, allowing sufficient time for the eye to heal.  Recovery of enhanced vision is slower with PRK when compared to iLASIK. However, long-term improvements with vision are identical to iLASIK.


As the eye ages, the lens loses its flexibility and becomes unable to focus on near objects. This natural aging process, known as presbyopia, typically begins to develop around the age of 40. Monovision is a surgical option to help reduce a presbyopic person’s dependency on reading glasses. Dr. Koenig typically corrects the dominant eye for distance, while the other eye is left slightly nearsighted, to allow for near/reading vision. The brain will learn to rely solely on one eye for distance vision and the other for near vision. Monovision is a middle-of-the-road solution between perfect distance vision and perfect near vision. Patients who choose monovision must often compromise some degree of sharp distance vision in order to avoid reading glasses.

It is important to remember that presbyopia is a progressive condition. As you get older, you may still need reading glasses, especially for more demanding tasks such as reading fine print. While monovision works well with most patients, not everyone is able to easily adjust. During your personalized evaluation, Dr. Koenig, iLASIK surgeon in Milwaukee, Wisconsin, will be able to help you determine if monovision is right for you.
