Benefits of Corneal Cross-linking
The corneal cross-linking treatment, also known as CXL, has brought a ray of hope for patients suffering from progressive keratoconus and corneal ectasia. It is a minimally invasive procedure that has shown significant benefits in halting the progression of keratoconus and, in some cases, even improving the shape and structure of the cornea. Here are some key benefits of corneal cross-linking:
Halting the Progression of Keratoconus and Corneal Ectasia: The primary benefit of corneal cross-linking is its ability to stop the progression of keratoconus and corneal ectasia. These are progressive eye diseases that, if left untreated, can lead to significant vision loss and may ultimately require corneal transplantation. By strengthening the cornea and creating new corneal collagen cross-links, CXL helps to stabilize the cornea and prevent further thinning and bulging.
Preventing the Need for Corneal Transplant: Keratoconus and corneal ectasia can lead to a thinning of the cornea to a point where a corneal transplant (deep anterior lamellar keratoplasty, or even a penetrating keratoplasty) may be the only option left. Corneal cross-linking will strengthen the cornea, and in most cases, eliminate the need for a corneal transplant. A corneal transplant can be very helpful in the right circumstance, but it is ideal to avoid a corneal transplant if possible since it comes with inherent risks such as rejection, infection, and other complications.
Improvement in Visual Acuity and Reduction in Astigmatism: Not all, but many patients experience a small improvement in visual acuity and a reduction in irregular astigmatism after undergoing corneal cross-linking. This can lead to a improved vision with glasses or contact lenses. While the primary goal of CXL is to halt the progression of the disease, the improvement in vision is a welcome benefit for many patients.
Strengthening the Cornea: The CXL procedure creates new cross-links between molecules and fibrils in the corneal tissue, thereby increasing the mechanical strength of the cornea. This strengthening of the cornea helps to restore and maintain its natural shape and improve its structural integrity.
Long-lasting Results: The effects of corneal cross-linking are long-lasting. It is designed to be a single treatment. Once the new cross-links are formed, they are expected to remain stable and provide lasting reinforcement to the cornea. This is not a temporary fix but a long-term solution for stabilizing the cornea and preventing further progression of the disease. The goal is to treat with CXL as soon as the diagnosis of keratoconus is made.
Minimally Invasive Procedure: Corneal cross-linking is a minimally invasive, outpatient procedure. It does not involve any incisions or sutures and has a relatively quick recovery period. This makes it a preferable option for many patients compared to more invasive surgical interventions.
Long Track Record: The CXL procedure was developed in Germany over 20 years ago. It has received approval in the United States from the Food and Drug Administration, which means it has undergone rigorous clinical trials and has been found to be safe and effective for the treatment of progressive keratoconus and corneal ectasia. It is the standard of care for keratoconus.
It is important to note that while corneal cross-linking has many benefits, it is not a cure for keratoconus or corneal ectasia. It is a therapeutic treatment aimed at halting the progression of the disease and preventing further vision loss. CXL will not completely fix the irregular shape of the cornea from changes caused by keratoconus. At Waite Vision, we believe in personalized care and will work with you to develop a treatment plan tailored to your specific needs and goals.

The Need for Corneal Cross-linking
The human eye is a marvel of biological engineering, and the cornea is its outermost layer, responsible for focusing about 70% of the light entering the eye onto the retina to create visual perception. A normally curved cornea is crucial for optimal vision, but keratoconus and corneal ectasia can lead to corneal thinning and bulging, causing distorted vision and eventually, vision loss. This vision loss is caused by a cone-like shape of the cornea and irregular astigmatism. This section will discuss the progressive nature of these diseases and the resulting need for corneal cross-linking.
Progressive Nature of Keratoconus and Corneal Ectasia: Keratoconus is a progressive eye disease that typically begins in adolescence or early adulthood and worsens over time if left untreated. The cornea thins and bulges outward into a cone-like shape, leading to distorted vision, light sensitivity (photophobia), and, in advanced cases, scarring of the cornea. Corneal ectasia is a condition exactly similar to keratoconus, but that occurs as a complication after refractive surgery, such as LASIK or PRK. The progressive thinning and distortion of the cornea can lead to significant visual impairment, impacting daily activities and quality of life.
Limitations of Glasses and Contact Lenses: In the early stages of keratoconus and corneal ectasia, glasses or contact lenses may help correct the vision distortion. However, as the diseases progress, the cornea continues to thin and bulge, making it challenging to achieve satisfactory vision correction with glasses or contact lenses. Specialized contact lenses, such as rigid gas-permeable lenses or scleral lenses, may provide better vision correction but can become uncomfortable to wear and may not be a viable long-term solution for all patients.
Risk of Corneal Transplantation: If keratoconus or corneal ectasia progresses to an advanced stage, a corneal transplant may become necessary. Corneal transplantation involves replacing the damaged cornea with healthy donor tissue from an eye bank. While this procedure can restore vision, it comes with risks such as graft rejection, infection, and other complications. Additionally, there is often a long recovery period, and sutures may be required to hold the donor cornea in place.
Given these challenges, there is a pressing need to halt the progression of keratoconus and corneal ectasia before they reach advanced stages. This is where corneal cross-linking comes into play. Since keratoconus is progressive, the sooner the CXL treatment, the better.
Corneal Cross-linking as a Preventive Measure
Corneal cross-linking (CXL) is a therapeutic treatment that strengthens the cornea and halts the progression of keratoconus and corneal ectasia. The newly created cross-links after CXL increase the mechanical strength of the cornea, preventing further thinning and bulging. This treatment can effectively stop the progression of the disease, thereby reducing the risk of vision loss and the need for corneal transplantation.
In summary, the progressive nature of keratoconus and corneal ectasia, the limitations of glasses and contact lenses, and the risks associated with corneal transplantation underscore the need for corneal cross-linking. This minimally invasive procedure is a game-changer for patients, helping to preserve their vision and improve their quality of life. At Waite Vision, we are committed to providing the best possible care for our patients, and we offer corneal cross-linking as a preventive measure to stop the progression of these debilitating corneal diseases.

The Corneal Cross-linking Procedure
The corneal cross-linking (CXL) procedure is a revolutionary treatment designed to halt the progression of keratoconus and corneal ectasia, two progressive corneal diseases that lead to the thinning and bulging of the cornea. By increasing the number of cross-links, or bonds, between collagen fibers in the cornea, the procedure strengthens the corneal tissue, restoring its shape and mechanical strength. At Waite Vision, we believe in using state-of-the-art techniques and technologies to offer patients the best possible outcomes. Here is a step-by-step description of the corneal cross-linking procedure:
Preparation: Before the procedure, the eye is numbed with anesthetic eye drops to ensure the patient’s comfort throughout the treatment. During the Dresden procotol, the ophthalmologist removes the epithelium, the thin outer layer of the cornea, to allow the riboflavin eye drops to penetrate the corneal tissue. This is known as the epithelium-off or epi-off technique. At Waite Vision, we do not remove the epithelium, but will keep it in place since it is safer with less risk for scarring or infection compared to an epi-off technique. Our protocol is equally as efficacious as the Dresden protocol.
Riboflavin Application: Riboflavin (vitamin B2) eye drops are applied to the cornea. Riboflavin is a photosensitizing agent that, when activated by ultraviolet (UV) light, interacts with the molecules in the corneal stroma creating new covalent bonds. The riboflavin eye drops are applied every few minutes for 30 minutes to ensure adequate saturation of the cornea.
Ultraviolet (UV) Light Exposure: Once the cornea is sufficiently saturated with riboflavin, the eye is exposed to a controlled amount of UV light for approximately 30 minutes. The UV light activates the riboflavin molecule , facilitating the formation of new cross-links between the collagen fibrils.
Bandage Contact Lens Application: After the UV light exposure, a bandage contact lens is placed on the eye to protect the cornea and promote healing if an epi-off procedure is performed. If epi-on is performed, no bandage contact lens is necessary. Antibiotic and anti-inflammatory eye drops are also prescribed to prevent infection and reduce inflammation.
Post-Procedure Care: The initial healing after CXL is uncomfortable. The UV exposure is similar to a sunburn on your cornea which is highly innervated and very sensitive. Sometime, numbing drops can be used to control the post-operative pain on the first day only. Patients are advised to avoid rubbing their eyes and to wear sunglasses to protect their eyes from bright light and UV exposure. Regular follow-up appointments with the ophthalmologist are essential to monitor the healing process and assess the outcome of the treatment.
The corneal cross-linking procedure typically takes about 1-2 hours and is performed on an outpatient basis. It may take several months for the cornea to fully heal and for the vision to stabilize. The epi-off technique is currently the only FDA-approved method in the United States.

Frequently Asked Questions About Corneal Cross-linking Utah
Can I wear contacts or glasses after corneal crosslinking treatment?
After the corneal crosslinking treatment, you may still use glasses, but will need to hold off on using contact lenses for about 3 days after the epi-on protocol we use. The treatment aims to halt the progression of keratoconus or corneal ectasia and stabilize the cornea, but it will not fully correct the vision, so glasses and contact lenses will still be necessary after the procedure. Your eye doctor will conduct a comprehensive eye exam and assess your corneal topography to determine the most suitable lens options for you.
Is the corneal crosslinking procedure painful?
During the procedure, there is no pain since numbing drops are used. Pain and discomfort after the corneal crosslinking procedure vary from patient to patient. Anesthetic eye drops are used to numb the eye prior to the procedure, which minimizes pain. After the procedure and after the numbing drops wear off, there is often intense burning. With an epi-on procedure, this burning will last from 8-10 hours. After the burning resolves, there is mild light sensitivity for about 24 hours. Some patients may experience dry eye syndrome or mild discomfort for the first few days after the procedure, which is usually manageable with over-the-counter pain medication and lubricating eye drops. At Waite Vision, we prioritize your comfort and provide detailed post-operative care instructions to help manage any discomfort.
Is corneal crosslinking suitable for treating Post-LASIK ectasia?
Yes, corneal crosslinking (CXL) is the recommended treatment for Post-LASIK ectasia. This condition occurs when there is a progressive thinning of the cornea after LASIK eye surgery. Corneal crosslinking works by creating new bonds in the corneal stroma, which helps to stabilize the cornea and halt the progression of ectasia. At Waite Vision, our experienced eye doctors and surgeons will conduct a thorough eye exam and assess your suitability for the corneal crosslinking procedure.
What is the role of riboflavin solutions in the corneal crosslinking procedure?
Riboflavin (vitamin B2) acts as a photosensitizing agent in the corneal crosslinking procedure. The riboflavin is activated by ultraviolet (UV) light, creating a singlet oxygen molecule which facilitates the formation of new covalent bonds between glycosaminoglycans and other molecules in the corneal stroma. This helps to strengthen the corneal tissue, restore its mechanical strength, and halt the progression of keratoconus or corneal ectasia. At Waite Vision, we use an effective epi-on CXL protocol to ensure the safety and efficacy of the corneal crosslinking treatment.
Can corneal crosslinking treat keratoconus?
Yes, corneal crosslinking (CXL) is an FDA-approved treatment for progressive keratoconus. It is designed to strengthen the cornea by creating new cross-links between the corneal molecules, which helps to stabilize the cornea and prevent further thinning and bulging. It is a minimally invasive outpatient procedure that has been shown to halt the progression of keratoconus and reduce the need for more invasive procedures like corneal transplants. At Waite Vision, we offer a proven corneal crosslinking method to help manage keratoconus and preserve your vision.
Do I need to see an ophthalmologist for corneal crosslinking?
Yes, it is essential to consult an ophthalmologist who specializes in corneal diseases and treatments to qualify for corneal crosslinking.
