A corneal transplant, or keratoplasty, is a surgical procedure to replace a damaged cornea.
The procedure involves removing either your entire cornea or a portion of it and replacing it with healthy tissue. Except in certain cases, the new corneas used in corneal transplants are entirely natural and come from the bodies of those who have chosen to donate their organs.
If you know that your cornea has been damaged for some reason, you should consider contacting an ophthalmologist at Ophthalmic Specialists of Michigan.
An ophthalmologist performs corneal transplants to resolve issues with the cornea of the eye.The cornea is transparent and allows light to enter the eyes. When the cornea is damaged, there may be pain, vision loss, and visible aberrations of the eye, such as discoloration and scarring.Your ophthalmologist may recommend a corneal transplant for various problems related to the eyes, such as:
Various types of corneal transplants are available. The one recommended for you would depend upon the reason why you need the transplant.
The endothelium and a thin layer of tissue that shields the endothelium from damage and infection are removed during this procedure. The excised tissue is replaced with donor tissue.Two kinds of endothelial keratoplasty exist: Descemet stripping endothelial keratoplasty (DSEK) and Descemet membrane endothelial keratoplasty (DMEK).DSEK involves replacing about a third of the cornea with donor cornea tissue. With DMEK, only a very thin layer of donor cornea tissue is used.
In this type of corneal transplant, the surgeon makes a precise circular incision through the full thickness of the cornea in order to remove a small round disk of cornea tissue. Then the donor tissue of the same size and shape is sewn into place.
Leaving the rear endothelial layer as it is, the surgeon excises bad tissue from the topmost corneal layers and then grafts healthy donor tissue in place.
When it’s not possible to use live cornea tissue from donors, artificial corneas can be used. This is called keratoprosthesis.
To be considered a good candidate for a corneal transplant, you:
A corneal transplant could restore your vision or bring it back to acceptable levels. Talk to your ophthalmologist at Ophthalmic Specialists of Michigan to get more information about this surgical procedure.
