The transparent layer in front of the eye is called the “corneal layer“. It allows us to see objects clearly. Light is, refracted as it passes through the cornea. This allows us to see.
In patients with damaged cornea, this layer narrows forward and swelling increases. This disorder shifts downward in the center of the cornea by gravity over time.
In this way, the patient gradually has myopia and astigmatism. Failure to correct this problem with glasses leads to visual impairment.
Keratoconus can be diagnosed with a routine eyes exam. Your ophthalmologist examines the cornea and measures its curvature.
This examination helps to determine whether there is a change in shape of the cornea. Your ophthalmologist examines the corneal surface using a special computer. Afterwards, it clearly shows the condition of the corneal surface.
Keratoconus disease has no age of onset. It can occur at any age. Early diagnosis of kerataconus is important.
- Clear, distorted and blurred vision.
- Progressive myopia and astigmatism.
- Inability to see clearly despite frequent changes in glasses.
- Double vision.
- Headache, eye strain, eyebrow pain.
- Eye hypersensitivity to light.
- Slight deterioration in vision due to straight lines that appear twisted or wavy
Treatment for keratoconus depends on the symptoms and the stage of the disease. In the early stages when symptoms are mild, your vision can be corrected with glasses.
You may then need to use special hard contact lenses to help focus the image properly.
There are other methods used in the treatment of keratoconus. The curvature of the cornea is tried to be corrected by surgically placing a small curved device into the cornea. The doctor uses a special UV light and eye drops to strengthen the cornea.
Doing so will help the cornea to flatten or harden, preventing it from becoming even more puffy.
- CCL (corneal cross linking)
- ICR (intracorneal ring)
- Cornea transplantation
