What Is Keratoconus
Keratoconus is a degenerative condition of the cornea which causes it to thin and bulge outward taking on more of a cone shape versus a dome shape. As the cornea bulges, the collagen tissue which gives the cornea its shape begins to stretch and ultimately scar. This unstable, thinner cornea leads to highly irregular astigmatism and ultimately very blurred vision not correctable by glasses or contacts.
Keratoconus Signs And Symptoms
Symptoms can vary so it is recommended that you consult with an eye specialist who can assess and diagnose the condition. Some signs of Keratoconus may include:
- Constant and regularly changing refractive errors with increasing astigmatism
- Blurry vision that is not correctable with glasses or contact lenses
- Increased light sensitivity
- Difficulty driving at night
- Halos around lights and ghosting (especially at night)
- Eye strain
- Headaches and general eye pain
- Eye irritation, excessive eye rubbing
