Dr. Seyed Farzad Mohammadi, a faculty member of the ophthalmology department and the head of the Translational Ophthalmology Research Center at Tehran University of Medical Sciences, who performed the surgery, said about this transplant: "One of the most challenging clinical scenarios that ophthalmologists face is the loss of the biological properties and characteristics of the eye’s surface. This surface is considered a highly complex biological tissue and may fail due to congenital diseases, eye injuries, or various other reasons. In such cases, there is a need for the transplantation of limbal stem cell-containing layers of the eye’s surface. Currently, the process of harvesting and transplanting this highly specialized and delicate layer from the donor's eyeball, which is a complex procedure, has been performed for the first time in the world at Farabi Hospital.
