Corneal Transplant (Full Thickness): Before Your Surgery

Skip to the navigation

What is a full thickness corneal transplant?

Anatomy of the eye

A full thickness corneal transplant is done to remove a diseased, infected, or scarred cornea. It's replaced with a healthy cornea from a person who has died. The cornea is the clear surface that covers the front of the eye.

In most cases, you will be awake during the surgery. The doctor will put medicine in your eye to numb it. You may also get medicine to help you relax. Or you may get it to make you sleep during the surgery.

Surgical tools are used to keep your eye open. You may feel some pressure in your eye. The doctor makes a small cut (incision) in your cornea. Then your cornea is removed. The doctor puts the new cornea over your eye and sews it into place. The stitches usually stay in place for 2 to 3 months. They are slowly removed over many months as the cornea heals.

This transplant takes about 1 hour. Most people go home on the day of the surgery.

After surgery, you will need to wear an eye patch for about a day. Then you will need to wear a clear eye shield or glasses to protect your eye. You'll use this until the eye has healed.

You will probably be able to go back to work or your normal routine in about 1 to 2 weeks. But your vision will still be blurry. You will need to avoid heavy lifting for about 3 to 4 weeks, or until your doctor says it is okay.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

What happens before surgery?

Surgery can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for surgery.

Preparing for surgery

  • Understand exactly what surgery is planned, along with the risks, benefits, and other options.
  • Tell your doctors ALL the medicines and natural health products you take. Some of these can increase the risk of bleeding or interact with anesthesia.
  • If you take blood thinners, such as warfarin (Coumadin), clopidogrel (Plavix), or aspirin, be sure to talk to your doctor. He or she will tell you if you should stop taking these medicines before your surgery. Make sure that you understand exactly what your doctor wants you to do.
  • Your doctor will tell you which medicines to take or stop before your surgery. You may need to stop taking certain medicines a week or more before surgery. So talk to your doctor as soon as you can.
  • If you have an advance care plan, let your doctor know. Bring a copy to the hospital. If you don't have one, you may want to prepare one. It lets your doctor and loved ones know your health care wishes. Doctors advise that everyone prepare these papers before any type of surgery or procedure.

What happens on the day of surgery?

  • Follow the instructions exactly about when to stop eating and drinking. If you don't, your surgery may be cancelled. If your doctor told you to take your medicines on the day of surgery, take them with only a sip of water.
  • Your surgery may be cancelled if you have an eye infection, your eye is swollen, or there are problems with the donor cornea.
  • Take a bath or shower before you come in for your surgery. Do not apply lotions, perfumes, deodorants, or nail polish.
  • Take off all jewellery and piercings. And take out contact lenses, if you wear them.

At the hospital or surgery centre

  • Bring a picture ID.
  • The area for surgery is often marked to make sure there are no errors.
  • You will be kept comfortable and safe by your anesthesia provider. You may get medicine that relaxes you or puts you in a light sleep. The area being worked on will be numb.
  • The surgery takes about 1 hour.

Going home

  • Be sure you have someone to drive you home. Anesthesia and pain medicine make it unsafe for you to drive.
  • You will be given more specific instructions about recovering from your surgery. They will cover things like diet, wound care, follow-up care, driving, and getting back to your normal routine.

When should you call your doctor?

  • You have questions or concerns.
  • You don't understand how to prepare for your surgery.
  • You become ill before the surgery (such as fever, flu, or a cold).
  • You need to reschedule or have changed your mind about having the surgery.
