Corneal transplant surgery (Full-thickness corneal transplant).
The cornea of the eyes is the clear, front window of the eye. It helps focus light into the eye so that you can see. The cornea is made of layers of cells. These layers work together to protect your eye and provide you clear vision.
The cornea of the eyes should be clear in a smoothy way and healthy for good vision. If it’s swollen, scarred or damaged, light is not focused properly on the eye. As a result, your vision is blurry, foggy or you see glare.
If the cornea of the eyes can’t be healed or repaired, your eyes doctor may recommend a corneal transplant for you. This is when the diseased cornea is replaced with a clear, healthy cornea from a human donor who chooses to donate (give) his or her corneas after their death to people who need them. All donated corneas are carefully tested to make sure that they are healthy and safe to use.
There are different types of corneal transplants. In some cases, only the front and middle layers of the cornea are replaced. In others, only the inner layer is removed. Sometimes, the entire cornea needs to be replaced.
Full-thickness Eyes corneal transplant:
Full-thickness corneal transplant is one of the Corneal Transplant Procedure and Surgery Options, Your entire cornea may need to be replaced if both the front and inner corneal layers are damaged. This is called penetrating keratoplasty (PK), or full thickness cornea transplant. Your diseased or damaged cornea is removed. Then the clear donor cornea is sewn into place.
Penetrating keratoplasty PK has a longer recovery time than other kinds of eye cornea transplants. Getting complete vision back after penetrating keratoplasty (PK) may take up to one year or longer.
In a penetrating keratoplasty PK there is an insignificantly higher risk than with other kinds of corneal transplants that the cornea will be rejected. This is when the body’s immune system attacks the new corneal tissue.
