Corneal Cross-Linking (CXL)

For whom is corneal cross-linking fit?

CXL is offered to patients with progressive keratoconus or corneal ectasia following refractive surgery or induced corneal weakening by either genetic or acquired means. Its most effective use is early on, where it will be used in combination with a preservation of vision and prevention of serious complications requiring corneal transfer.

How is cross-linking in cornea done?

Corneal cross-linking actually consists of three basic steps and all in 1 hour they can be accomplished:-

• Preparation- In general, the eye is numbed with anesthetic drops and a thin layer of the outer part of the cornea called epithelium is usually removed so that it can absorb better the drops of riboflavin.
• Riboflavin Application- Herein the drops of riboflavin continuously drip on the cornea for about 30 minutes.
• UV Light Activation – The cornea will be exposed to UV light for an additional 10-30 minutes, thereby activating the riboflavin, and creating new links (cross-links) between collagen fibers, which will strengthen the cornea.

What are the types of corneal Cross-Linking?

There are two different types of CXL which mainly include:-

• Epi-off Cross-Linking – The epithelium is removed for better riboflavin absorption.
• Epi-on Cross-Linking – The epithelium is left intact, which means it is a less invasive procedure and doesn’t give much discomfort but prolongs treatment time.

Is Corneal Cross-Linking painful?

The procedure is completely without pain as it involves the use of anesthetic drops; however, some people might feel mild discomfort, irritation, and light sensitivity in the recovery phase.

How long does the procedure take?

Corneal cross-linking typically takes around 60-90 minutes, which includes preparation and post-procedure.

What are the advantages people stand to gain from corneal Cross-Linking?

The advantages of the procedure include:-

• Halting Progression – It stops keratoconus and corneal ectasia from increasingly developing and hence saves vision.
• Minimally Invasive – It reduces the chances of more invasive procedures like corneal transplantation.
• Strengthened and Stable Cornea – The eye’s structure eventually becomes stronger and more stable, and some symptoms, such as visual distortion, would be reduced.
• Applicable Broadly – It gives attention to patients of various ages and can, therefore, be done early to prevent potential complications from getting serious.

What are the possible risks of Corneal Cross-Linking?

While the procedure is regarded as absolutely safe, certain risks and side effects could include:

• Discomfort or sensation of a foreign body for a few days.
• Light sensitivity for a couple of days after the procedure.
• Visual haze or decreased night vision, which usually clears with time.
• Rarely, infection, delayed healing, and corneal scarring.

At Tender Palm Eye Hospital, advanced technology and strict protocols are available for ensuring safety and minimum risk to the patient.

What is the recovery experience like after Corneal Cross Linking?

Recovery has various stages:-

• Initial Healing (First Week) – This time may have mild discomfort, irritation, or blur vision on top of the worst healing- with epithelial removal patients should have. Contact lens has been put on the cornea during the period of 3 days in which the contact will be taken off.
• Continuation of Visual Improvement – Vision may fluctuate for a few weeks until it stabilizes and improves gradually over time, usually taking 3 to 6 months.

Can they provide trial following with the post-procedure?

In connection to that, the patients are given a general orientation of optimum healing with the following requirements:-

• The prescribed antibiotic and anti-inflammatory eye drops must be used as directed.
• Rubbing the eyes should not be done to prevent injury or infection.
• Use of sunglasses should be when in outdoor settings to protect the eyes from bright light.
• They should attend to the medical check-up scheduled with the ophthalmologist.

When can they resume their normal activities?

In fact, most patients would resume lighting activities in about 2 to 3 days. Aside from that, tedious labor and some high-risk activities where the eyes can be targeted should be avoided for two weeks at the minimum.

How is the long-term prognosis after Corneal Cross-Linking?

Corneal cross-linking is a really successful technique to stop keratoconus progression in 90% of patients. Instead of reversing already existing damage, it locks the cornea into a stable condition where vision will be maximal. Most patients will continue to use either corrective contact lenses or spectacles for optimum vision, but their situation can be stabilised and managed without surgery.

Is it possible to have Corneal Cross-Linking together with other treatments?

• Yes, the CXL is often used in routine combination with another surgical procedures, like Intacs (corneal implants) or specialized contact lenses, for better visual outcome.
• The techniques and devices available at Tender Palm Eye Hospital are the latest and most advanced for corneal cross-linking.
