Symptoms
By Mayo Clinic staffSigns and symptoms of keratoconus may change as the disease progresses. They include:
- Blurred or distorted vision
- Increased sensitivity to bright light and glare
- Problems with night vision
- Headaches from eyestrain
- Sudden worsening or clouding of vision, caused by a condition in which the back of your cornea ruptures and fills with fluid (hydrops)
When to see a doctor
See your eye doctor (ophthalmologist or optometrist) if you have astigmatism (irregular curvature of the eye) and your eyesight is worsening rapidly. Your eye doctor also will likely look for signs of keratoconus during routine eye exams.
If you're considering laser-assisted in-situ keratomileusis (LASIK) eye surgery, make sure your doctor checks for signs of keratoconus before you proceed.
