Corneal cross-linking is a reliable means of permanently stopping the progression of keratoconus. Keratoconus, a relatively common condition affecting 1/2000 people, typically begins shortly after puberty. By causing corneal thinning and bulging, keratoconus can lead to blindness even in young people. Keratoconus is not reversible and until recently the only treatment has been hard contact lenses–a treatment that improves vision, often with significant discomfort, but does nothing to slow the progression of the disease.
If you have been recently diagnosed with either keratoconus or post-LASIK ectasia it is important that you: 1) Never rub your eyes, and 2) Stop the worsening of your corneal warpage as soon as possible with corneal cross-linking.
