If the cornea is cloudy or scarred from an eye injury or disease, vision
becomes blurred. Scar tissue and other disorders can block light rays and prevent
normal vision. The effect has been described by many patients as somewhat like
looking through rippled glass.
Fortunately, the clouded cornea can be removed and replaced by clear, healthy
tissue from a generous eye
donor. A person may obtain a corneal transplant through
the request of a qualified eye surgeon (Ophthalmologist). This type of surgery has
restored sight and changed the lives of thousands from children, to senior citizens
to those in the prime of life.
What is a Corneal Transplant or grafting?
First, the cloudy tissue is removed with a cylindrical cutting instrument called a
trephine. The same trephine is used to cut out the donor cornea so that the shapes
are identical. Then, the clear donor cornea is sewn into place. If the graft is successful,
light rays will once again be focused onto the retina.
What are the indication of corneal grafting?
The most frequent indications :
1. Pseudophakic bullous keratopathy- which is a corneal decompensation that
occasionally follows cataract surgery.
2. Corneal ulceration.
3. Corneal scars.
4. Keratoconus.
5. Herpes simplex and Varicella zoster viral infections or fungal infection leading to scarring.
6. Fuch’s endothelial dystrophy.
7. Congenital opacities of the cornea.
8. Chemical burns of the eye.
9. Opacity of cornea due to any injury.
The Corneal Transplantation Procedure
cloudy or diseased cornea
The Donor cornea is prepared using a corneal trephine to create the corneal “button.” The corneal button will become the transplanted cornea.
The diseased, or scarred, cornea is then removed using a corneal trephine, creating a “bed” for the transplant cornea.
Finally, the donor cornea is gently sewn into place with ultra-fine sutures
