Corneal Crosslinking is a treatment for an eye problem called keratoconus.
In this condition, the front part of your eye, called the cornea, thins out and gets weaker over time. This makes it bulge into a cone shape, which can distort your vision and make it difficult to see clearly.
Doctors use special eye drops and ultraviolet A (UVA) light to make the tissues in your cornea stronger. That stops the bulge from getting worse.
It’s called “crosslinking” because it adds special bonds between the collagen fibers in your eye. They work like support beams to help stabilize the cornea.
