Preparing The Corneal Transplant Surgery

The Corneal Transplant Surgery:
If you are taking any other medication, ask your ophthalmologist whether you should continue it. You will probably be asked not to eat or drink anything for several hours before the surgery.
Usually a local anesthesia is used for surgery, so you will be awake but feel no pain. Intravenous medications will help you relax. The nerves in your eye will be completely numbed so you will not be able to see or move your eye. Sometimes the doctor may use general anesthesia.

The Trnsplant Procedure :
For the transplant, the doctors use an operating microscope and very delicate instruments. Once the old cornea is removed, the new cornea is stitched into place. The sutures or stitches are barely visible and are not painful, althoughyou might feel some irritation or a scratching sensation for a few days.
If necessary, other procedures may be performed at the same time as your transplant. For example, a cataract may be removed and replaced with an intraocular lens(IOL). An IOL may be replaced or removed. The vitreous gel may be removed from the eye and replaced with fluid. A damaged iris may be repaired. Your ophthalmologist will advise you about them.
Some Potential Risks :
As with other surgical procedures, a corneal transplant involves some risks- most of them can be treated.
  • eye infections
  • failure of the donor cornea to function normally
  • rejection of the donor cornea by your body
  • cataract (clouding of the eye’s lens)
  • glaucoma(build-up of fluid, leading to increased pressurein the eye)
  • bleeding from the iris
  • swelling or detachment of the retina
Rejection of a Transplant – the dander signals!
Rejection of a transplanted cornea can occur any time, but is more likely to happen in the first year after surgery. Unfortunately, rejection reduces the chance of success of any repeat corneal transplantation. However, this can be prevented by timely diagnosis and appropriate manaement.
Watch out for these dangersignals:
  • Redness
  • Sensitivity to light
  • Vision loss
  • Pain
The acronym ‘RSVP’ can help you remember these symptoms. If you notice anyof these symptoms in your operated eye, however minor they may seem and regardless of the time of day, contact us immediately. If this is not possible, visit the nearest ophthalmologist, preferble a cornea specialist.
