Sutureless corneal transplant surgery DSEK – DMEK
In most of the cornea diseases the pathology is related only to one layer of the cornea. In those cases replacing only the diseased layer of the cornea is the choice of treatment. DSEK and DMEK are the corneal transplantation techniques where only the inner endothelial layer of the cornea is transplanted. These surgeries can be performed through smal incisions and no permenant sutures are used like the full thickness corneal transplant.
Who can have sutureless corneal transplant?
Cornea is made up of five different layers within a 500 microns thickness. Endothelial cell layer is the innermost part of the eye. These cells function to sustain the corneal clarity which is essential for a good visual acuity. In some genetic diseases and after complicated surgeries where the endothelium can be damaged (e.g. cataract surgery) cornel edema may be observed.
Most frequent indications fo the sutureless corneal transplant surgery are:
How sutureless corneal transplant (DSEK - DMEK) is performed?
If the other parts of recepients cornea are intact, the donor cornea is prepared manually, with a microkeratome or with the help of a femtosecond laser. The custom prepared lamellar cornea tissue is then inserted into the eye through a small incision and transplanted with a specialized technique without using any sutures.. This surgery may be performed under local or general anaesthesia.
What are the advantages of sutureless corneal transplant (DSEK - DMEK)?
Since the eyeball is not opened as in a full thickness graft; the eye is more resistant to trauma after the surgery.
