Treating Keratoconus

With Collagen Cross Linking (CXL)

A comparison of a Normal Eye and an eye with Keratoconus

Corneal collagen cross-linking (CXL) is a technique to treat patients with keratoconus. Keratoconus can cause the cornea to become weak, thin, and irregularly shaped.Instead of keeping its normal round shape, corneas with keratoconus can bulge forward and have a cone shape, causing poor vision. Our practice is proud to be able to provide the CXL treatment to our patients who could benefit from this advanced technology.

Normal corneas have cross-links between its collagen fibers that keep it strong and able to retain its normal shape. With keratoconus, the cross-links of the cornea are not there and the cornea becomes weak. This weakened structure causes the cornea to bulge outwards. The cross-linking procedure adds cross-links or“cross beams” to the cornea, making it more stable. These new cross-links help strengthen the cornea and stop the thinning process.

Research studies have shown that CXL prevents further vision loss in over 95% of patients. The same studies have also shown that CXL can often prevent the need for a corneal transplant and allow patients to wear contact lenses/glasses more comfortably and safely.

Since keratoconus is a condition that often runs in families, it’s important to arrange a screening for all family members of patients with keratoconus. If caught early, CXL may halt the progression of keratoconus and prevent the need for corneal transplant.
