Types of Cornea Transplant
• Penetrating Keratoplasty
• Endothelial Keratoplasty
• Boston Keratoprosthesis
At Haider Eye Care, one of our specialties is cornea transplants. We are one of the few practices in Louisivlle who offer these procedures. A cornea transplant is a procedure done to replace tissue in the cornea with donor tissue. The cornea is where light enters the eye and is the most important part of the eye to allow us to see clearly.
Cornea transplants are often done to restore vision of a person who has a damaged cornea. Some conditions that are treated with cornea transplants include:
Keratoconus, a condition that causes the cornea to become thinner and possibly change in shape
Cornea scarring, from injury or eye infection
Hereditary diseases such as Fuchs’ Endothelial Dystrophy, where the cells lining the cornea begin to deteriorate
To be eligible for a cornea transplant, a thorough eye exam is done to try and figure out underlying causes or conditions that could potentially cause complications after the transplant. We then take comprehensive measurements of the eye to determine the cornea transplant size needed. Unrelated eye problems are treated prior to surgery, like swelling or infection, to increase the chances of a successful surgery.
At Haider Eye Care, Dr. Haider performs 3 different types of cornea transplants. There are many factors taken into account to determine which transplant procedure will be performed, like cornea thickness.
Types of Cornea Transplants
PK is a full-thickness cornea transplant. This procedure is done while under local or general anesthesia. A special tool is used to remove a circular piece of the damaged tissue, which is then replaced by donor tissue. The new corneal tissue is held together by small stitches and most patients require a single night hospital stay following the procedure.
EK is the process of transplanting the back part of the cornea. There are two main techniques to perform this surgery, Descemet’s Stripping ENdothelial Keratoplasty (DSEK), and Descemet’s Membrane Endothelial Keratoplasty (DMEK). DSEK replaces the inner lining of the cornea, making up about 30% of the whole cornea. DMEK replaces only the inner layer of cells in the cornea. Both of these procedures allow for a faster recovery of vision and come with a lower risk of complications. Instead of stitches, this procedure allows for the donor tissue to be held in place with the use of an air bubble.
BK is a procedure that involves donor tissue as well as a device. During the implantation, the small device is made up of two plates with donor corneal tissue in the middle. This surgery is often combined with other procedures and is the primary route of treatment for cases of repeat graft failure and pediatric corneal opacities.
Most patients who receive a corneal transplant will have vision at least partially returned. It is important for patients who have undergone this procedure to follow-up regularly with an eye doctor to monitor progress and prevent complications. Once your cornea is healed, several weeks after the procedure, your eye doctor can make improvements to vision by correcting unevenness in the cornea or prescribing corrective lenses or contacts.
