The name literally means “conical or cone-shaped cornea” and rarely appears until puberty or older. In keratoconus the cornea becomes stretched and thins at its centre, and the thinned part of the cornea bulges making the vision more shortsighted and irregular. As a result the vision is distorted. The stretching of the cornea tends to progress but the rate varies. Both eyes are affected but the condition may not be at the same stage in both eyes. The majority of people with keratonconus have no family history of the condition and are very unlikely to have affected children. Treatment usually begins with the use of rigid contact lenses, although soft contact lenses or spectacles may still be suitable in the early stages. The rigid contact lenses help to provide the best possible vision but they do not affect the rate of progression of the condition. As the condition progresses good vision may be difficult to maintain and contact lens tolerance may vary. A condition called ‘hydrops’ may also occur. This may result in a sudden drop in vision and is due to a break in Descemet’s membrane allowing fluid to leak into the stroma of the cornea. This can be uncomfortable and cause the eye to water. It may also lead to scarring.
