Corneal transplant surgery, also known as keratoplasty, is a procedure that replaces a damaged or diseased cornea with a healthy cornea from a donor. This surgery can restore vision, reduce pain, and improve the appearance of the eye. Understanding the process is crucial for those considering this treatment. Below, we delve into what happens during corneal transplant surgery.

Pre-Operative Preparations

Before undergoing corneal transplant surgery, patients have a comprehensive pre-operative evaluation. This typically includes a detailed eye examination, a discussion of medical history, and a review of any medications being taken. The eye doctor will explain the procedure, expected outcomes, and potential risks, ensuring the patient is well-informed and comfortable.

Anesthesia Administration

On the day of the surgery, the patient is usually administered either local anesthesia or general anesthesia, depending on the case and patient preference. Local anesthesia numbs the eye while the patient remains awake, while general anesthesia allows the patient to sleep through the entire procedure.

Corneal Removal

Once anesthesia takes effect, the surgeon carefully opens the eyelids using a device called a lid speculum. The damaged or diseased cornea is then removed. The surgeon will create a circular incision in the cornea, making sure to leave the corneal tissue around the edge intact. This technique is vital for ensuring the stability of the eye after the transplant.

Donor Cornea Placement

After excising the affected cornea, the surgeon will prepare the donor cornea. The donor tissue is cut to match the size and shape of the eye's remaining corneal tissue. The healthy donor cornea is then positioned in the eye. The surgeon uses fine stitches, or sutures, to secure the donor cornea in place. These sutures may be removed later, depending on the healing process.

Finishing the Procedure

Once the new cornea is securely in place, the surgeon carefully checks for any bleeding and makes sure the eye is stable. The eyelids are then gently closed, and the patient may have a protective eye shield placed over the eye to aid in the healing process.

Post-Operative Care and Recovery

After surgery, patients are taken to a recovery area where they are monitored until they are ready to go home. Post-operative care typically includes prescribed eye drops to prevent infection and reduce inflammation. Follow-up appointments are crucial for monitoring the healing process and for potential suture removal.

Patients may experience blurred vision or discomfort during the initial recovery period. Full recovery and optimal vision improvement may take several months. It is essential for patients to adhere strictly to post-operative instructions provided by their surgeon for the best possible outcomes.

Conclusion

Corneal transplant surgery is a complex but highly beneficial procedure for those with severe corneal issues. Understanding the different stages of the surgery—from preparations and anesthesia to the transplant itself and recovery—can help demystify the process and alleviate concerns for prospective patients.
