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. 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. 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 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 of drying. 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 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!

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, and glares and halos in the line of vision. Risks are rare, and the vast majority of patients who undergo LASIK do not experience significant complications.

What Kind of Technology Does Chicago Cornea Consultants Offer?

Our LASIK surgeons utilize the Intralase laser, which precisely forms the corneal flap without the need for cutting, and Custom Cornea, which allows our surgeons to customize your LASIK treatment using Wavefront-guided treatment profiles.

Long-term Vision Correction

For many years, LASIK has been used to provide patients with long-term vision correction. LASIK, which stands for Laser-Assisted In Situ Keratomileusis, can reduce or eliminate the need for corrective lenses. 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 use two of the most technologically advanced laser instruments the VISX Star S4 IR, and Alcons Allegretto Wavelight system. We also offer blade-free IntraLase LASIK (iLASIK) and utilize the latest version of the IntraLase iFS, which creates a corneal flap with improved speed. Our doctors 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, and halos or glares at night. These side effects should all subside within a week or two after surgery. 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. call any of our offices and ask to speak to the Vision Correction Surgical Coordinator, or use the contact form below.
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.
At Chicago Cornea Consultants, our doctors take great care in maintaining ocular health for our patients. However, a number of our patients voice concerns regarding soft lines and wrinkles around the eyes and other regions of the face. We have responded by introducing cosmetic procedures like BOTOX® Cosmetic through our Chicago practice.
This last decade has brought great advancements in intraocular lens implants.

We encourage you to learn more about these advanced options and schedule a consultation to determine which lens is right for you.
