What is LASIK?

Happy woman sitting outside after LASIKLASIK, or Laser-Assisted In Situ Keratomileusis, is a surgical procedure that is designed to reduce your dependency on glasses and contact lenses. Here at Chicago Cornea Consultants™, our LASIK surgeons use the latest in laser vision correction technology to ensure each patient receives optimal results.

In addition to LASIK, our surgeons also offer Epi LASIK, LASEK, and PRK which are forms of “advanced surface ablation”, or ASA.  These procedures may be more suitable for patients with very high amounts of refractive errors, thin corneas, or both. We have three convenient locations to serve you, including Chicago, Highland Park, and Hoffman Estates.


LASIK is a laser vision correction procedure that treats refractive errors, such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism (oval curvature), etc. by removing corneal tissue beneath the surface of the cornea.

During the LASIK procedure, a flap is created on the surface of the cornea with femtosecond laser technology. A computer-controlled excimer laser is then used to remove the proper amount of corneal tissue. In less than one minute, the excimer laser reshapes the internal layer of the cornea, or “stroma”.

The thin flap of corneal tissue is then folded back into its original position, where it bonds after only a few minutes. The entire LASIK procedure usually takes about five to seven minutes per eye.

No stitches or eye patches are required after LASIK and the healing time is usually very fast. In fact, most patients are able to return to their regular daily activities the day after their LASIK procedure. Also, the results of LASIK are long-lasting, so you can view the world with a clear, crisp vision for years to come!

  • Are you over the age of 18?
  • Have you had a stable glasses or contact lens prescription for at least two years?
  • Do you have sufficient corneal thickness?
  • Are you affected by one of the common types of vision problems or refractive errors, including myopia (nearsightedness), hyperopia (farsightedness), or astigmatism?
  • Are you free of diseases that may reduce the effectiveness of LASIK or your ability to heal properly and quickly?
  • Are you adequately informed about the benefits and risks of LASIK?

If you think you may be a good candidate for LASIK, contact Chicago Cornea Consultants™ in Chicago, Highland Park, or Hoffman Estates to schedule a consultation with one of our surgeons.

What are the Potential Benefits of LASIK?

Most patients who undergo LASIK experience significantly improved vision and many patients can return to work or normal daily activities the day after surgery. Visual recovery is rapid and patients report little or no post-operative pain. The risk of scarring or developing corneal haze is minimal in comparison to other vision correction procedures.

Are There Risks Associated with LASIK?

There are some risks associated with LASIK, including dry eyes, persistent eye pain or discomfort, glares, and/or halos when driving at night. Fortunately, the risk of significant complications is low.

As technology has advanced, the LASIK surgery procedure has become safer and more effective. Our Chicago practice uses the most advanced laser technology to ensure optimal results and a fast recovery. Contact us today to learn more.

LASIK Surgery Procedure

LASIK surgery is a procedure that relies on advanced technology and precision to reshape the cornea, correcting nearsightedness, farsightedness, and astigmatism. After a topical anesthetic is applied, a thin flap is created on the surface of the cornea.

The flap is lifted, allowing the excimer laser to reshape the inner layers of the cornea. Once the necessary alterations have been made, the corneal flap is replaced, acting like a natural bandage. Typically, LASIK surgery takes just 5-10 minutes per eye.

Laser Technology

At our Chicago practice, we have access to two of the most technologically advanced laser instruments the VISX Star S4 IR, and the Alcons Allegretto Wavelight system. We only perform blade-free femtosecond laser LASIK and utilize the latest technologies.

The experienced eye surgeons at Chicago Cornea Consultants™ select the appropriate laser after reviewing each patient’s unique vision correction needs. To learn more about our advanced technology, we invite you to visit our LASIK technology page.

LASIK Recovery

LASIK eye surgery is a quick outpatient procedure. Patients will return home in sunglasses or protective eye shields. We recommend that our patients plan to rest their eyes for several hours after undergoing LASIK surgery. Following this initial period of rest, vision may be slightly blurred.

However, most patients do notice an immediate improvement in vision. Eye drops will be prescribed to help patients avoid infection, and keep the eyes moist. Other side effects include mild discomfort, sensitivity to light, halos, and/or glare when driving at night.

These side effects usually subside within a week or two after surgery but can persist for a few months. Following recovery, most patients gain 20/20 vision or better.

Traditionally, presbyopia, which happens to all of us as we age, has always meant glasses for clear reading vision. It's a condition not even correctable by laser vision correction. Luckily, there is an option. Refractive lens exchange allows patients a clear alternative to reading glasses and is capable of reducing or eliminating presbyopia by using an advanced multifocal intraocular lens.

Keratoconus describes a cornea that weakens as collagen fibers deteriorate, causing the cornea to adapt a cone-like shape. Keratoconus can cause blurred vision, light sensitivity, glares, and decreased night vision. In its early stages, keratoconus may be treated with the use of prescription glasses or contact lenses. Keratoconus is also one of the most common reasons for corneal transplant, and one of the most successful.

It's estimated that a million or more Americans have glaucoma and don't even know it. People with glaucoma often do not experience any symptoms until they begin losing their peripheral vision. One of the scariest things about glaucoma is that it usually has no symptoms in the early stages, earning glaucoma the name "silent thief of sight." Anyone can be at risk, so it's important to have your vision regularly examined.
