3 STEPS TO VISUAL ACUITY
CROSS-LINKING
The cross-linking procedure (CXL – Corneal Collagen Cross Linking) is a proven, widely recognized method of surgical treatment of keratoconus. It aims to stop or slow down the progression of the disease. The procedure involves soaking the cornea with riboflavin (vitamin B2) and then irradiating it with ultraviolet radiation, which cross-links the collagen fibers that make it up, increasing its stiffness and stopping the disease.
Depending on the stage of the disease and anatomical conditions, we may decide to additionally modify the procedure by performing phototherapeutic keratectomy (PTK) or photorefractive keratectomy based on corneal topography (Topo-guided PRK). Thanks to this, the excimer laser (usually used for laser vision correction) is able to improve the geometry of the top of the keratoconus and thus improve the quality of vision. This is a therapeutic procedure and cannot be confused with typical laser vision correction.
