Corneal Cross-Linking
Corneal cross-linking (CXL) is an in-office procedure designed to strengthen the cornea (the clear, outer lens on the front of the eye) when it has become weakened by laser vision correction surgery or an eye condition called keratoconus. The procedure uses ultraviolet (UV) light and special eye drops containing vitamin B2 to strengthen the cornea. Much like rebar provides strength to concrete, cross-linking provides strength to the cornea by creating connections within the cornea.
The two basic types of corneal cross-linking are:
- Epithelium-off: The thin outer layer (epithelium) of the cornea is removed to allow the vitamin B2 drops to more easily penetrate the corneal tissue. This is the only FDA-approved type of CXL.
- Epithelium-on (or transepithelial CXL): The epithelium of the cornea is left intact and requires a longer period of time for the vitamin B2 drops to be absorbed into the corneal tissue. This type of cross-linking is not FDA-approved but is being studied in clinical trials to determine its effectiveness.
CXL has been found to be highly effective in preventing the progression of keratoconus and post-refractive surgery corneal weakening. In fact, patients who undergo CXL typically see their vision improve by a few lines on the eye chart. The procedure carries little risk, and the benefits are significant. UAB Callahan Eye Hospital is excited to offer this procedure to patients who need it.
