Conventional Crosslinking vs. Fast Crosslinking: What's the Difference?

Did you know there are different types of crosslinking to treat keratoconus?

In this article, we’ll explain the differences between conventional crosslinking and fast crosslinking, and discuss the benefits and outcomes of each.

What is Crosslinking?

Crosslinking is a surgical procedure aimed at stabilizing keratoconus, a condition that causes thinning and bulging of the cornea. The goal of crosslinking is to strengthen the cornea, preventing its protrusion and stabilizing vision.

🔍 How It Works:

Riboflavin Application: Riboflavin (vitamin B2) is applied to the cornea.

Ultraviolet Light: The cornea is exposed to ultraviolet light to activate the riboflavin.

Corneal Strengthening: The process creates new covalent bonds between collagen fibers, making the cornea more rigid and stable.

Difference Between Conventional Crosslinking and Fast Crosslinking

Conventional Crosslinking

Conventional crosslinking, also known as the Dresden protocol, involves:

Procedure Time: 30 minutes of continuous riboflavin application with ultraviolet light.

Light Intensity: Lower intensity of ultraviolet light over the duration of the procedure.

Fast Crosslinking

Fast crosslinking is a quicker version of the procedure, offering the same results with less application time. Its characteristics include:

Procedure Time: 15 minutes of riboflavin and ultraviolet light application.

Light Intensity: Higher intensity of ultraviolet light to compensate for the shorter exposure time.

Comparison of Results

Scientific studies show that there is no significant statistical difference in the final results between the two methods. Both are effective in stabilizing keratoconus, but fast crosslinking offers greater patient comfort during the procedure.

Why Choose Fast Crosslinking?

At Ampla Oftalmologia, we use fast crosslinking in most cases due to the following benefits:

✔ Comfort: Shorter procedure time, increasing patient comfort.

✔ Efficacy: Equivalent final results to conventional crosslinking.

✔ Recovery: No additional post-operative complications.

Conclusion: Which is Best for You?

If you have keratoconus and are considering crosslinking, it’s important to discuss with your ophthalmologist which method is best suited for your specific case. Both methods are effective, but fast crosslinking may offer a more comfortable experience.
