A recent study found that “despite advances in diagnostic tools keratoconus is often diagnosed at a relatively late stage.”3 Currently we see more advanced keratoconus patients getting corneal cross linking, because it is being diagnosed at a later stage. If there is any suspicion you may have keratoconus, we recommend getting scans to see if you have keratoconus. Remember, the earlier we diagnose keratoconus, the earlier we can do corneal cross linking.
