The first successful corneal transplant was performed in 1905 by Eduard Zirm, an Austrian ophthalmologist.
Zirm transplanted a donor cornea from a recently deceased person into the eye of a patient who had lost their vision due to a corneal disease. The procedure was considered a success because the patient regained some sight.
This groundbreaking procedure paved the way for modern corneal transplantation, which is now a common and effective treatment for a variety of eye conditions.
It's important to note that corneal transplants are different from full eye transplants, which involve replacing the entire eye. Full eye transplants are still highly experimental and are not yet widely available.
