The Gift of Sight - Agree to Donate Your Corneas
Ever looked at your driver's license, in the area marked "donations." If you look closely, you can elect to donate your corneas if you have passed away. If you've never thought about what corneal donation is, or why its important, read this article, and you'll hopefully reconsider.
At the very front of the normal eye, is the clear cornea. More than just a front window, the clear cornea focuses most of the light entering the eye, onto the retina.
Injury or disease can damage the clear cornea, making it opaque. Because light cannot pass through, vision can be reduced, blurred, or lost.
Corneal transplantation is a technically refined surgical procedure used in very difficult cases, where the cornea is damaged beyond repair. During the surgery, the damaged cornea is removed. The clear donor cornea replaces the damaged one; and vision can be restored.
After a cornea has been donated from a deceased person, it is taken and re-sized into a button. It is now the exact size of the portion of cornea that will be removed for a patient undergoing transplant surgery.
Next, a circular trephine incises the damaged cornea. Special micro-scissors complete the incision. The damaged cornea is removed, and the clear donor cornea is placed.
Temporary sutures hold the donor cornea during healing. The sutures are eventually removed, and vision is restored.
How It Works
While synthetic corneas have been created and implanted, these are often expensive, and still in the experiment stage. Corneal transplant surgery has provided complete restoration of vision to many throughout the world, mostly due to the valuable gift of donors. Donors can be of any age and background.
Imagine, you yourself allowing someone to see their granddaughter's face. Please, reconsider signing your donor card today, and give the gift of sight.
