Corneal Cross Linking

 

 

Collagen Cross Linking
It is a surgical procedure that is indicated for:
1. Patients with keratoconus, which is a congenital corneal disease. It starts in early childhood and progresses quickly to result in distortion of the normal corneal shape and curvature.
2. Patients with corneal ectasia which is very similar in to keratoconus but occurs after corneal refractive surgery such as LASIK or LASEK where the cornea has become very weak

 

Procedure
One drops of Riboflavin is put on the eye every 5 minutes for 30 minutes and then the cornea is illuminated with UV-A light for approx.10 – 30 minutes (depending on the cross-linker used). The riboflavin forms bonds on the stromal layer of the cornea. The eye is covered with a bandage contact lens which is removed 5 to 7 days after the procedure. The cornea will be examined and scanned at frequent intervals to monitor for its stability.

The video shows how one of the methods we do where we preserve the corneal epithelium. It also shows how does collagen cross-linking works.
