Corneal transplant surgery (Partial 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.
Partial thickness corneal transplant:
Partial thickness corneal transplant is one of the Corneal Transplant Procedure and Surgery Options, Sometimes the front and middle layers of the eye cornea are damaged. In this case, only those layers are removed. The endothelial layer, or the thin back layer, is kept in place. This kind of transplant is called deep anterior lamellar keratoplasty (DALK) or also it called partial thickness corneal transplant. deep anterior lamellar keratoplasty (DALK) is commonly used to treat keratoconus or bulging of the cornea.
Recovering time after deep anterior lamellar keratoplasty (DALK)is shorter than after a full cornea transplant. There is also less risk of having the new cornea rejected.
