Keratoconus & Contact Lenses

Keratoconus & Contact Lenses

Keratoconus is a condition that affects the cornea (surface) of the eye. Find out how our specialist clinicians diagnose and manage Keratoconus.

What is Keratoconus?

Keratoconus is a condition that affects the cornea (surface) of the eye. The cornea is the clear, outer layer of the eye, mainly made up of water and collagen. Keratoconus causes the cornea to become thin creating an irregular cone-shaped surface resulting in poor focussing and blurred vision. When the cornea becomes thin it starts to lose its normal integrity and scarring may occur.  

Keratoconus is usually diagnosed in people in their teens or early twenties, generally, their astigmatism will increase, and they will experience blurred vision. During the early stages, specialist contact lenses are usually worn to help prevent the progression.

How does Keratoconus affect vision?

Keratoconus is a progressive condition and is usually first diagnosed by an optometrist during an eye examination. During the earliest stages, vision may seem unaffected, but as it progresses, Keratoconus causes blurred vision; and if left untreated, corneal scarring can occur, stopping the eyes from focusing correctly. Even in advanced Keratoconus, contact lenses can usually be used to correct the vision, but if scarring does occur, surgery may be required.

What are the symptoms of Keratoconus?

Most people with Keratoconus are unaware they have the condition. The earliest symptom is usually blurred vision that is not easily fixed with standard glasses or contact lenses.

Oher symptoms of Keratoconus can include:

- Eye irritation
- Headaches
- Increased sensitivity to bright light
- Difficulty seeing at night
- Glare and halos around lights
