About the Cornea

The cornea is the clear outer layer located at the front of the eye. It helps with focusing light that enters the eye so that you can see clearly. It also provides much of the focusing power of the eye. Most refractive errors, such as farsightedness, nearsightedness, and astigmatism are due to issues with the cornea.

Common Issues that can occur include:

Keratoconus is a progressive eye disease that occurs on the cornea, the clear part on the front surface of your eye. Keratoconus causes the cornea to become gradually thinner, which can lead to the outward bulging of the cornea. This can cause a cone like appearance to occur within the cornea. The disease can cause vision to become extremely blurry and many patients complain of sensitivity to light.

Corneal Collagen Cross Linking

Corneal collagen cross-linking, or CXL for short, uses ultraviolet (UV) light and vitamin B2 (riboflavin) eye drops to strengthen the corneal tissue. This treatment is the first of its kind to have the ability to slow or halt the progression of keratoconus, and it also improves the vision in over 50% of the patients that are treated. In the past, patients with keratoconus would often have to have a full thickness corneal transplant. But now, corneal cross-linking may allow patients with this eye disease to live a normal life by slowing or stopping the progression of keratoconus.

Fuchs’ Dystrophy/Dsaek

Fuchs’ dystrophy is a disease of the cornea that affects the endothelium layer, which is the innermost layer of the cornea. The endothelium layer consists of a group of cells that help keep the cornea clear by pumping out excess fluid. When the cells undergo degenerative changes, they can diminish and fluid can start to build up. This condition causes the cornea to swell, become cloudy and cause a loss of clear vision.

In order to manage Fuchs’ dystrophy and to improve vision, corneal surgeons today can perform a partial corneal transplant called Descemet Stripping Automated Endothelial Keratoplasty (DSAEK), which removes the damaged endothelial cells and replaces them with healthy donor cells to improve the clarity of the cornea.
