What Is Keratoconus?
Keratoconus is a progressive condition in which the cornea — the clear front surface of the eye — gradually thins and bulges outward into a cone shape. This irregular shape distorts the way light enters the eye, causing blurred and distorted vision that glasses alone often can’t correct.
Keratoconus usually begins in the teens or early twenties and can progress for years. Early diagnosis and treatment are the best way to protect your vision.
Signs and Symptoms
- Blurred or distorted vision, often worse in one eye
- Frequent changes in your glasses prescription
- Increased sensitivity to light and glare
- Halos or streaking around lights at night
- Difficulty with night driving
Treatment Options
Corneal Cross-Linking
A minimally invasive treatment that uses special eye drops and UV light to strengthen the cornea and slow or stop the progression of keratoconus.
Specialty Contact Lenses
Rigid gas permeable, hybrid and scleral lenses create a smooth optical surface over the irregular cornea for clearer vision.
Corneal Transplant
In advanced cases, replacing part or all of the cornea with healthy donor tissue can restore a clearer, more regular surface.
Frequently Asked Questions
Can keratoconus be cured?
There is no cure, but treatments like corneal cross-linking can halt its progression, and specialty lenses or surgery can restore functional vision. Regular monitoring is key.
Will I go blind from keratoconus?
Keratoconus rarely causes blindness. With timely treatment, most people maintain good, functional vision throughout their lives.
