We perform partial replacement and full thickness corneal transplants
A corneal transplant involves replacing a diseased or scarred cornea with a new one. When the cornea becomes cloudy, light cannot penetrate the eye to reach the light sensitive retina. Poor vision or blindness may result. The corneas are usually donated from an eye bank for this procedure, and eye drops are needed after the surgery.
When possible, the eye care specialists on the medical staff at Baylor Scott & White Health will do a partial replacement of the cornea such as an endothelial keratoplasty or anterior lamellar keratoplasty. These newer surgeries are usually safer and result in quicker return of vision.
However, many conditions are still best managed with a full thickness corneal transplant called a penetrating keratoplasty.
Corneal transplant eligibility
To determine who is a good candidate for a corneal transplant, the patient must be evaluated. Patients are considered suitable if they have considerable corneal deterioration. Patients with corneal deterioration will have cloudy vision and are not able to see clearly through their affected eye.
Patients are usually referred for a transplant by their ophthalmologist and are scheduled for a corneal consultation with us if the physician suspects corneal damage.
What to expect
Eligible patients must be healthy enough for surgery to receive a donor cornea. Patients undergoing a corneal transplant will be able to use any donated cornea. Unlike other types of transplants, corneal transplants do not require the donor and recipient to have the same blood type.
Nevertheless, sometimes the body rejects the foreign tissue. Anti-rejection medication is given to the patient after the transplant surgery to help their body accept the corneal tissue. If rejection does occur, a second transplant can be performed.
Who are the donors?
Donors are deceased individuals who, prior to death, agreed to donate their organs. Baylor Scott & White coordinates with eye banks, such as the Lonestar Lion’s Eye Bank in Manor, Texas, to secure corneas for transplantation.
Risks and benefits of corneal transplant
The primary benefit of corneal transplantation is total restoration of vision.
The risks of corneal transplant include:
- Astigmatism, which can be caused by a ripple in the tissue during surgery. Corrective lenses may be needed to correct this problem.
- Glaucoma (high pressure in the eye that can cause vision loss).
- Sometimes, the body rejects the corneal tissue. Medication is given to the patient after the transplant surgery to help their body accept the corneal tissue. In a small number of patients, however, the body rejects the donor cornea, resulting in cloudy vision. If rejection does occur, a second transplant can be performed.
- Blindness if the surgery is not successful.
