Corneal Disorder Treatment
What Are Corneal Disorders?
The cornea is the eye’s outermost layer. It is the clear, dome-shaped surface that covers the front of the eye. A corneal disorder is anything that causes the cornea to become damaged or irregularily shaped. There are many causes of corneal disorders. One of the most common is keratoconus, a disease that causes the cornea to undergo progressive thinning and thus protrude outward, forming a conelike curvature. This irregular curvature leads to blurred and distorted vision. Keratoconus most commonly occurs in both eyes, but can occur in only one eye. Other causes of corneal disorders include:
- Eye injuries
- Hereditary corneal disease
- Corneal damage from previous eye surgery
Treatment for Corneal Disorders
Various refractive eye surgery techniques change the shape of the cornea in order to reduce the need for corrective lenses or otherwise improve the refractive state of the eye. Non-surgical treatments can include hard or rigid gas-permeable contact lenses to transiently reshape the cornea in order to improve the refractive state of the eye or reduce the need for eyeglasses and contact lenses.
