Cells mother to improve transplantation of cornea.
grafts obtained from healthy patient’s eye and serve to regenerate the area damaged.
Spain, January 2012.- The Alicante General Hospital Ophthalmology service uses stem cell grafts in patients who failed prior cornea transplant. In this way increases the likelihood of success of a new operation and reduces the risk of a rejection. Each year carried out 3 or 4 such operations.
The procedure is to remove the tissue with stem cells from the healthy eye of the patient, situated around the cornea. These cells are implanted in the diseased eye to regenerate the area of the epithelium and thus perform later transplantation with greater guarantees of success. There are occasions where eye damage suffered by the patient are bilateral and not allowed to do with their own stem cells grafting, so it has to resort to a tissue donor. In these cases the use of grafting of families with greater immunological affinity, such as parents or siblings can be partly alleviated the drawback. However, this alternative “increases the risks of rejection, the patient need to take immunosuppressive.
“The ophthalmology service of the General Hospital was a pioneer in transplantation of cornea in the province, intervention has been practicing more than 30 years with nearly 2,000 made interventions. Each year become more than one hundred, one of the highest figures at the national level.
