The cornea is the front part of the eye that plays a crucial role in vision. It refracts, or bends light as it enters the eye to focus it on the retina. It also protects the eyes from dust, wind and foreign particles. Given the important role that the cornea plays, it is important to ensure that it is healthy. Here are some signs of a cornea problem that you should know about so that you can seek medical assistance without delay:
Pain or discomfort:
Pain or discomfort in or around the eye should not be ignored as it is usually a sign of a cornea problem. It can range from mild, uncomfortable feelings, including excessive tearing, dryness, or feeling like something is stuck in the eye.
As the cornea is responsible for the eye’s focusing power, any damage to the cornea can result in blurred vision. If you are experiencing blurred vision while reading or driving, you must see an eye doctor immediately.
Redness in the eye can indicate an issue with the cornea. Infection, inflammation, or even a foreign object stuck in the eye can be a sign of an infection or other complications. If left untreated, a cornea problem can worsen.
Sensitivity to light:
A damaged cornea can make the eye more sensitive to light. If you are experiencing discomfort because of bright lights, you should see an eye doctor to get to the root cause of the problem.
If you wake up with a crusty eye and discharge, it is important to pay attention as it could be more than just an irritated eye. In fact, these symptoms can indicate a serious problem with the cornea that requires medical attention. Corneal infection or inflammation might cause these signs and symptoms, which could lead to a potentially dangerous corneal ulcer if untreated.
Difficulty with contact lenses:
The cornea holds the contact lens in place. If your contact lenses are not fitting well or causing discomfort suddenly, you must see an eye doctor. It could be a sign of an underlying cornea problem.
Common cornea problems are::
- Corneal abrasions: A corneal abrasion is a scratch on the surface of the cornea. This can be caused by foreign particles in the eye or wearing wrong-size of contact lenses.
- Corneal dystrophies: Corneal dystrophies are a group of inherited disorders that affect the cornea.
- Keratoconus: It is a condition in which the cornea bulges, leading to blurred vision and light sensitivity.
- Fuch’s dystrophy: Fuch’s dystrophy is a condition in which the cells that produce the innermost layer of the cornea die. This causes the cornea to swell.
When is cornea surgery needed?
A cornea transplant is needed to repair or replace a damaged cornea. The transplant is also done to alleviate pain or other symptoms caused by cornea diseases.
