It is the most modern and safe method of keratoconus correction, a very minimally invasive procedure aimed at stopping the progression of keratoconus.
What is the procedure?
Cross-linking is performed under local anesthesia in the form of eye drops. The procedure itself does not take long and is not too complicated. First, the corneal epithelium is removed, then its tissue is soaked with riboflavin solution, and then – for about 30 minutes – irradiated with safe UV rays. As a result, new cross-links (hence the name ‘cross linking’) are formed between the collagen fibers within the cornea. This makes the cornea resistant to further deformation and strengthened. After the end of the ultraviolet radiation emission, a protective lens is put on, which is worn until the first checkup.
The procedure is completely safe and does not cause significant complications. Complications that may occur after crosslinking are temporary corneal swelling, cloudiness or clouding.
The basic examination in the diagnosis of keratoconus is the topographic map of the cornea with the analysis of many eye parameters. This test is non-invasive and provides a wealth of information on the degree of the taper, progression over time. The test allows to determine whether the cross-linking procedure is possible in a given patient.
