Corneal collagen cross-linking is a technique that’s been around for a while now but recent studies have now proven that this technique can in fact halt the progression of the disease Keratoconus for up to 5 years.
It is a non-surgical method utilising a UVA light source, which is delivered onto the Cornea, together with a chemical mix largely made up of riboflavin for strengthening the collagen fibres within the corneal structure. The combination of the UVA light and the riboflavin creates a joining or bonding of the chemical structures within the cornea.
The effect is similar to the change we commonly see when toasting bread. A fine slice of bread bends easily and has little strength but after toasting, the bread results in being stronger and slightly more compact.
