Eye Rubbing, Allergy and Keratoconus

Repeated eye rubbing is associated with keratoconus and its progression. Allergy does not mean that a person will develop keratoconus, but chronic itch can create a cycle of rubbing and mechanical stress on the cornea.
Why do people rub?
Ocular allergy, dry eye, eyelid inflammation, contact lenses and habit may all cause itch or foreign-body sensation. The cause should be treated rather than relying only on willpower.
Practical steps
- Seek assessment for persistent itch.
- Treat allergy or dry eye according to diagnosis.
- Use a cool compress without pressing on the eye.
- Review contact-lens fit and hygiene.
- Avoid unsupervised redness-relief drops.
When should the cornea be mapped?
Tomography should be considered when rubbing is accompanied by changing astigmatism, reduced vision, asymmetry or family history—particularly in children and teenagers.
Is stopping rubbing enough?
No. It is an important risk-reduction measure but does not replace monitoring or CXL when progression is present.
