Cornea Transplant – What Should You Know?

Cornea Transplant is a surgical procedure that replaces a person’s cornea. The transplant is usually an outpatient procedure, and patients are given local anesthesia to numb the area. Afterwards, patients can go home the same day. The procedure usually takes 30 minutes to an hour. During the procedure, doctors perform the transplant through a microscope. The patient will wear an eye patch for four days after the surgery.


Infection after cornea transplantation is an important complication that affects the recipient eye. Infection after transplantation can occur as a result of a variety of factors. In this study, microbiology results of 59 episodes of infection were reviewed. Eighty-four percent of the cases were caused by Gram-positive organisms. Ten percent were caused by Gram-negative organisms. Fungi accounted for five percent of the episodes.

Two patients in this study were diagnosed with ulcers at the graft-host junction, and two had corneal perforation as a result. In the other, a patient with a failed graft and a Peter’s anomaly developed a large staphylococcal ulcer. After the infection was controlled with PKP, the patient’s eye was cleared. Four other patients developed an atrophic ulcer in their host cornea.


Cornea transplant surgery involves removing the damaged central part of a patient’s eye and implanting a donor cornea. Often, the donor is obtained from a cornea bank. It is first screened for infectious diseases and then placed into the open space left by the old cornea. A very fine suture is then used to secure the new cornea in place. This suture stays in the eye for several months while the eye heals and is removed gradually during routine office visits.

The surgery usually takes less than an hour and most patients can go home the same day, or spend the night. While there is a small risk of rejection by the body, patients typically will need a few weeks of antibiotics after surgery. The patient will also need to wear glasses or shields for the first few weeks after surgery. Corneal transplantation can take up to 18 months to achieve full vision.

Degenerative changes

A cornea transplant is a type of surgery that replaces the cornea of an eye with a donor cornea. The procedure involves making a small incision in the cornea of the recipient eye and harvesting the donor cornea. The graft is then inserted into the recipient eye through this incision. The surgeon can use different techniques for insertion, such as using a specialized instrument called a pull-in corneal graft or using endothelial grasping forceps.

The surgery is relatively safe and requires no significant downtime. However, some people may experience rejection to the transplanted tissue. About one out of every 10 transplants will result in the body’s immune system attacking the donated tissue. However, this is not a permanent problem and can be reversible with eye drops. The procedure can be performed under general anesthesia, making it an excellent choice for patients who want to avoid pain.


If you have recently undergone cornea transplant surgery, you may be worried about the possibility of rejection. However, there are several precautions you should take to reduce your risk of this potentially serious complication. First, you should follow all post-surgical instructions carefully. This includes not rubbing or pressing on your eyes for several days. It is also important to follow all prescribed medications.

The most common symptoms of rejection after cornea transplant include cloudiness and deterioration in vision. Rejection is most likely to occur if it is not detected early, but if it is diagnosed early, there is a 90 percent chance that you will be able to reverse the condition. Early rejection usually starts with increased redness and decreased vision, which should improve within a few days.

Newer techniques

Newer techniques in cornea transplant surgery aim to improve the effectiveness of transplanted corneas. As corneal opacity is a major cause of vision loss, cornea transplantation is a valuable way to correct this condition. Cornea transplantation can be performed in patients with a range of corneal diseases.

DMEK transplant surgery is a procedure in which the diseased inner layer of the cornea is removed and replaced with a thin layer of donor cornea. This surgery is not invasive and only requires the patient to lie flat with their faces turned upwards after the procedure. This technique offers the best chance for 20/20 vision and quick recovery, according to researchers.

Although corneal transplant surgery has a good success rate, some patients still experience rejection. About one out of 10 transplants will be unsuccessful due to an immune system attack on the donor tissue. In such a situation, patients are given eye drops to suppress the immune system and avoid corneal rejection.
