LAMELAR CORNEAL TRANSPLANTATION: DMEK, DESAEK or DALK
Specialists in DMEK, DSAEK or DALK techniques in Madrid for precise corneal transplants
LAMELLAR AND PENETRATING CORNEAL TRANSPLANTATION
Mainly, there are two groups of corneal transplants, the lamellar corneal transplant, in which only the affected layers of the cornea are replaced. For this transplant the DMEK, DSAEK and DALK techniques and, on the other hand, the penetrating transplant is an ideal alternative when all the corneal layers are damaged.
The cornea is made up of five layers:
WHAT LAMELLAR CORNEAL TRANSPLANTATION TECHNIQUES EXIST?
DALK - Deep anterior lamellar keratoplasty (Deep Lamellar Anterior Keratoplasty).
Partial corneal transplant in which the stroma of the patient is replaced by a healthy one, thus maintaining the Descemet’s membrane and the endothelium, which means the possibility of rejection is lower.
The anterior lamellar corneal transplant is especially indicated in cases in which the endothelium is healthy, but nevertheless the anterior part of the cornea is damaged. For example:
Risks of this technique:
The risks that can arise in this technique are:
Benefits of this technique:
On the other hand, this technique has multiple benefits:
1.- DSAEK Technique
In the transplant of corneal endothelium with the DSAEK technique, only the endothelial cell layer is substituted, together with a thin layer of corneal stroma.
It presents a lower risk of rejection than with a penetrating transplant.
2.- DMEK Technique
In the transplant of corneal endothelium using the DMEK technique, only the cell layer is transplanted. This technique is usually used in ocular diseases such as Fuchs endothelial dystrophy, in which there is an alteration of the endothelium.
It presents a high success rate.
