Your cornea is your window to the world. It is the clear front part of your eye. This dome-shaped tissue plays an important role in protecting your eye and refracting light into it, thus ensuring your eye health and contributing to clear vision.

Issues with your cornea can compromise your vision and impact your quality of life. Here, the talented ophthalmologists at Mack Eye Center discuss problems that can affect your cornea.

Refractive Errors

Refractive errors make it difficult to see clearly. These types of problems occur due to the shape of the eye. The most common refractive errors are nearsightedness (myopia), farsightedness (hyperopia) and astigmatism. We offer a range of vision correction options for patients experiencing refractive errors, including glasses, contact lenses and refractive surgery.

Corneal Abrasion

A corneal abrasion occurs when the cornea is scratched or scraped. This can occur when a fingernail, pet claw or other foreign object scratches the eye. If you are suffering from a corneal abrasion, you should see an experienced ophthalmologist or optometrist who can examine the injury and provide further treatment if necessary.

Corneal Infections and Ulcers

A corneal ulcer is an open sore on the cornea. It is often caused by an injury to the eye or an infection. Symptoms include eye pain, red or bloodshot eyes, excessive tearing, pus and vision problems. A corneal ulcer is a medical emergency and should be treated immediately.

Dry Eye

Dry eye is a common condition that results when eyes do not have sufficient lubrication. Severe dry eye can cause cornea problems, including corneal abrasion and corneal ulcers. Mack Eye Center offers a number of dry eye treatment options, including prescription eye drops, intense pulsed light (IPL) therapy and PROKERA.


Blepharitis is an inflammation of the eyelids that can cause a number of uncomfortable symptoms, including redness, swelling, irritation and itchiness. It can lead to other serious problems like damage to the cornea.

Pterygium (Surfer’s Eye)

A pterygium is a raised fleshy growth that can spread to the cornea. As it grows across the eye, it can impact your vision. Treatment often depends on the size of the growth and can range from eye drops to surgery.


Keratoconus occurs when the cornea thins and bulges into a cone shape, resulting in blurred and distorted vision. While there is no cure for keratoconus, it can be managed. The first step in treatment is a comprehensive eye exam. The ophthalmologists at Mack Eye Center offer comprehensive eye exams to diagnose keratoconus.

Fuchs’ Dystrophy

Fuchs’ dystrophy occurs when fluid builds up in the cornea, causing it to swell and thicken. This can cause eye discomfort, glare and distorted vision. If you are experiencing any symptoms, talk to your eye doctor. Treatment options include medication, contact lenses and surgery.
