Corneal Cross-linking (CXL)

CCC has been offering CXL to our patients since 2010. We have performed more corneal crosslinking procedures than any other practice in the metro Chicago area. Patients are referred to us for CXL from throughout the midwest.

Corneal Cross Linking (CXL) has revolutionized the treatment of corneal ectasia,which is an abnormal shape of the cornea.  The cornea is the transparent “window” of the eye and plays a very significant role in how well we see.  In various disease processes, like keratoconus and post-LASIK corneal ectasia, the cornea loses its normal shape, becoming thin and “cone-shaped”. These changes in the cornea can continue to progress over months and years leading to frequent changes in prescription and, if undetected or untreated, may result in permanently decreased vision.  Often at a late stage, the only remedy is corneal transplantation, which is a major surgical procedure.  Fortunately, with early detection and CXL treatment, many patients may be able to maintain good vision and prevent the need for corneal transplant surgery.

CXL is an in-office procedure in which Riboflavin (a Vitamin B derivative) and Ultraviolet (UV) light are used to create cross-links between the collagen fibers of the cornea, making it more rigid and preventing further changes from occurring.

The use of CXL was first reported in 1998 and has been performed routinely for these conditions, worldwide, since 2006.  However, the treatment of corneal ectasia with CXL was not approved in the USA until 2016. With FDA-approved “epithelium-off” CXL, the epithelium or top layer of the cornea is removed prior to treatment.  Both eyes are generally NOT treated simultaneously with this technique. Because the surface layer of the cornea is removed, a “bandage” contact lens is placed for comfort and to promote healing. This lens is typically removed several days after the procedure, once the surface layer has healed.  However, vision will likely be blurrier than it was prior to surgery during the healing, process, which can take many weeks.

“Epithelium-ON”, or “trans-epithelial” CXL is available to our patients as part of an IRB-supervised clinical trial.  This technique IS usually performed bilaterally, as there is generally only one night of blurry vision and minimal discomfort after this procedure.

The team at Chicago Cornea Consultants, Ltd. Is pleased to offer both forms of CXL to our patients with keratoconus or corneal ectasia.  We performed “epithelium-ON” CXL as part of the “CXL-USA” clinical trial from 2010-19, with excellent results. We continue to offer this procedure as part of another clinical trial.  Both eyes can undergo treatment simultaneously, the visual recovery is faster than with the “epithelium-off” technique and there is decreased risk of scarring, infection and discomfort.

Many studies have demonstrated the extremely high success rate of CXL in preventing further vision loss.  It is important to remember that CXL is unlike LASIK or PRK in that the goal of the procedure is to PREVENT vision loss. Patients will still require glasses or contact lenses in order to correct their vision after this procedure. We have found that patients achieve a SUBSTANTIAL improvement in contact lens tolerance following CXL, particularly when specialized keratoconic contact lenses are properly fitted.  Many patients who have previously become contact lens INTOLERANT find that they can once again wear them successfully. While most people do not require more than one treatment, CXL can be repeated when necessary.

When is it time for CXL? If you have a diagnosis of keratoconus or corneal ectasia, you may be a candidate.  Please call any of our offices and schedule your consultation now.

Does Insurance Cover CXL Treatment?

Unfortunately, we have yet to see an insurance policy cover this treatment.

Is Financing Available?

Convenient, affordable financing is available to help our patients get the treatment they need before their keratoconus or another similar condition progresses to the point where they can no longer have CXL.

LASIK , 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, Ltd., our LASIK surgeons 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. 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.

Loss of near vision, or presbyopia, happens when your natural lens loses elasticity, making it difficult to change your focus to see objects up close.  It affects most people in their 40s and early 50s. The hassle and inconvenience of readers is driving many patients to look for a better way to improve their near vision without glasses. The Raindrop Near Vision Inlay is a simple solution to presbyopia. This innovative and unique procedure is an effective alternative to the hassle of readers. Raindrop Near Vision Inlay is a minimally invasive and long term solution to improve near vision without glasses.
