Corneal Collagen Cross-Linking (CXL)

The eye is one of the most complex and elegant organs of the human body. It’s perhaps no wonder, then, that there are so many problems that can affect a person’s vision. It’s for that reason that our Chicago cornea surgeons are ready to meet with you and help you with your various needs. We at Chicago Cornea Consultants™, Ltd. are well trained and well equipped to address vision problems of many different kinds.

About Keratoconus

One such vision problem that we can help people with is keratoconus. Keratoconus is a generally common vision problem in which the cornea of the eye becomes thin and begins to protrude. The eye becomes cone shaped due to this protrusion, resulting in distorted vision.

Causes and Symptoms of Keratoconus

Keratoconus is sometimes linked to vigorous rubbing of the eyes as has also been associated with health conditions such as eczema, asthma, and various allergies. There is often a genetic factor at work with keratoconus, which basically means you run a higher chance of getting it if it runs in your family. Such matters will be taken into account by our our Chicago optometrists and ophthalmologists when you visit for a consultation.

Some common symptoms of keratoconus include:

  • Blurry vision
  • Distorted vision
  • Glare
  • Light sensitivity
  • Irritation of the corneas

Treatment Options for Keratoconus

Traditional treatments for keratoconus usually involved the use of corrective lenses to improve vision. In some cases, a corneal transplant was performed. At our practice, we offer the latest in custom cornea and LASIK technology, which is why we’re proud to offer patients corneal collagen cross-linking as a treatment.

Corneal Collagen Cross-Linking (CXL)

Although not fully FDA approved here in the United States, collagen cross-linking (CXL) has yielded good outcomes in studies performed in Europe since 1999 for various forms of keratoconus.  We offer corneal collagen-cross-linking (CXL) here as part of a large USA study of the procedure. The treatment has proven remarkably successful in Europe where it has been used since 1999, and we anticipate that it will eventually be approved for use here in the United States given its effectiveness.

How Corneal Collagen Cross-Linking Works

Corneal collagen-cross-linking helps to strengthen the cornea and hence resist the outward protrusion caused by keratoconus. The cornea is strengthened by reforming new crosslinks between its collagen fibers.

The entire treatment involves safe eye drops fortified with riboflavin administered to the cornea. The first set of eye drops are and are administered once every two minutes for 30 minutes. The second set of eye drops are administered one every two to five minutes for 30 minutes while the patient looks at an ultraviolet light.


LASIK eye surgery is a procedure that is designed to reduce your dependency on eyeglasses and contact lenses. Here at Chicago Cornea Consultants™, our LASIK surgeons and eye doctors use the latest in laser vision correction technology to ensure each patient receives optimal results.

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.

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.

Dry eye can result from a lack of sufficient production of your own natural tears, with an inability to provide adequate lubrication for your eyes.
