Corneal transplantation, also known as corneal grafting, is a surgical procedure where a damaged or diseased cornea is replaced by donated corneal tissue (the graft). When the entire cornea is replaced it is known as penetrating keratoplasty and when only part of the cornea is replaced it is known as lamellar keratoplasty .
Treatment of patients whose vision is less than 20/200 in the affected eye. Patients with failed corneal transplant using donor cornea and have little or no vision left. Patients with non-autoimmune diseases, congenital birth defects and other ocular problems. Patients who do not have access to corneal transplant tissue
Osteo-odonto-keratoprosthesis (OOKP), also known as "tooth in eye" surgery, [1] is a medical procedure to restore vision in the most severe cases of corneal and ocular surface patients. It includes removal of a tooth from the patient or a donor.
The first successful cornea transplant was performed in 1905 and the first eye bank was founded in 1944. Currently, in the United States, eye banks provide tissue for over 80,000 cornea transplants each year [ 1 ] to treat conditions such as keratoconus [ 2 ] and corneal scarring .
In November 2023, surgeons at NYU Langone Health announced the first successful eye transplantation, [8] which was carried out as part of a partial face transplant in an operation that took 21 hours. [8] The recipient, Aaron James, had lost the left side of his face with his eye, nose and mouth in a high-voltage power line accident. [8]
A corneal button is a replacement cornea to be transplanted in the place of a damaged, diseased or opacified cornea, normally approximately 8.5–9.0mm in diameter. [1] It is used in a corneal transplantation procedure (also corneal grafting) whereby the whole, or part, of a cornea is replaced. [ 2 ]
It involves excising a damaged section of cornea, and replacing it with a section (or "flap") of the patient's own conjunctiva. [ 1 ] It is named for Trygve Gundersen (1902 – February 24, 1987), an American ophthalmologist of Scandinavian descent, who first described the procedure in 1958 at the Massachusetts Eye and Ear Infirmary .
Penetrating keratoplasty, a common type of corneal transplantation, is commonly performed for extensive corneal dystrophy. [citation needed] With penetrating keratoplasty (corneal transplant), the long-term results are good to excellent. Recent surgical improvements have been made which have increased the success rate for this procedure.
