Corneal transplantation refers to the replacement of all or part of the cornea (the front window of the eye) with a donor cornea. It was first performed in the early 1900s. During all types of corneal transplantation, the diseased part of the patient’s cornea is removed and replaced with healthy corneal tissue from a human donor.

What is corneal transplant surgery?

Corneal transplantation refers to replacement of all or part of the cornea; the specific transplant type is dependent on the underlying problem.

There are many different reasons why the cornea may be damaged and lose its clarity and transparency leading to loss of vision. These can include infective causes such as the herpes simplex virus (cold sore virus) or contact lens related infection, traumatic injuries, inherited diseases such as Fuchs’ dystrophy or lattice dystrophy, or even previous cataract or glaucoma surgery.

The optical function of the cornea may also be affected by conditions that lead to a change in it’s shape including keratoconus or pellucid marginal degeneration, or due to prior infection or injury.

Often, instead of transplanting the entire cornea, only the diseased portion is transplanted. In keratoconus, this means leaving the endothelial cell layer undisturbed and only transplanting the anterior (front) part of the cornea (Deep anterior lamellar keratoplasty or DALK).

Treatment types are varied including penetrating keratoplasty, lamellar surgery or selective endothelial keratoplasty; your surgeon will recommend the best treatment option for you. Or you can book a consultation with us and find out how our surgeons can tailor the treatment based on your specific needs.

Types of corneal transplants

  • A full-thickness transplant is called a penetrating keratoplasty (PK). During this procedure, a circular piece of damaged cornea from the centre of your eye is removed and replaced with the donated cornea.
  • Techniques for transplanting only part of the cornea have also been developed. Depending on the condition you are suffering from, a partial thickness transplant may be the best option for you, as the procedures often have a faster recovery time and a lower risk of complications. This type of surgery is called lamellar (layered) surgery
  • The latest development in corneal transplantation is a procedure called DMEK, where just the affected back membrane of the cornea is transplanted- a layer that is just 10 microns thick.
