Common Cornea Problems

The cornea is the transparent protective layer of your eyes. Along with the white of your eyes, it can act as a barrier against dust, bacteria and other substances from damaging your eyes. Your cornea also filters out some of the sun's ultraviolet rays. But not much, so your best bet is to wear a pair of sunglasses when you're outdoors.


It also plays a key role in vision. When light enters your eyes, it is refracted or bent by the curved edges of the cornea. This helps determine how well your eye can focus on objects close-up and far away.


If your cornea is damaged by disease, infection or injury, the resulting scars can affect your vision. This can distort or block light coming into your eyes.


When your cornea is damaged, your vision will decline. To restore your vision, you can have a corneal transplant. The corneal transplant can repair the vision of some people. Doctors need to use needle holders, medical forceps, eye scissors, and alligator forceps when performing corneal transplant.



Structure of The Cornea

To better understand the cornea, you need to know its structure. The cornea is generally composed of three layers.


Epithelium: The epithelium is the outermost layer of the cornea. It prevents outside matter from getting into your eyes. It also absorbs oxygen and nutrients from tears.


Stroma: The stroma is the thickest layer in the middle of the cornea, which lies behind the epithelium. It's mainly made of water and proteins that make it resilient but strong.


Endothelium: This is a monolayer of cells on the back of the stroma. Aqueous humor, a transparent liquid in the anterior chamber of your eyes, often comes into contact with this layer. It's like a pump. The stroma absorbs excess liquid and the endothelium pulls it out. Without this function, the stroma will accumulate water. Your cornea will become opaque and blurred, and so will your vision.

Symptoms of Cornea Problems

If the cornea is only slightly damaged, it will repair itself, and in the process, you may feel pain, blurred vision, tears, red eyes and sensitive eyes to light. These symptoms are accompanied by other eye problems, so they may indicate more serious problems requiring special treatment. When you have the above symptoms in your eyes, you need to go to the hospital for examination. 


In our daily life, we need to pay attention to the health of our eyes. Don't rub your eyes with your hands. There are a lot of bacteria on your hands. These bacteria may infect your eyes. In addition, you can't wear contact lenses while sleeping, which also increases the risk of eye infections.
