This will depend on which layers of your cornea are affected. It’s not always necessary to replace all layers of the cornea - Mr Patel will suggest the most appropriate type of cornea transplant surgery.
- Penetrating Keratoplasty (PK) is the conventional technique whereby all layers of the cornea are removed and replaced.
- Deep Anterior Lamellar Keratoplasty (DALK) is a modern technique that is performed to replace only the outer two layers.
- Descemet Stripping Automated Endothelial Keratoplasty (DSAEK) and Descemet Membrane Endothelial Keratoplasty (DMEK) are modern techniques that selectively replace the inner layer of the cornea.
This varies from person to person and depends on the type of cornea transplant performed. Visual recovery may be faster in patients that have undergone a partial thickness transplant.
You will be reviewed within a week of the surgery and then at intervals of between 1 and 3 months for the first 6 months, depending on the type of cornea transplant and how your eye is settling.
There are general risks that apply to all transplant surgery like rejection, glaucoma, infection and loss of vision but Mr Patel will discuss the specific risks that may be applicable to you.
