A Canadian man named Brent Chapman regained his sight after 20 years of blindness thanks to a groundbreaking "tooth-in-eye" surgery performed in Vancouver. Chapman, who lost his vision at age 13, was one of three people to undergo this innovative procedure in Canada for the first time. The surgery, originally developed in the 1960s, is considered a last resort for severe corneal blindness. The complex two-part procedure involves removing the patient's tooth, inserting a plastic lens into it, and then stitching this assembly into the eye socket.
Teeth are ideal for this surgery because they're made of the hardest substances the human body produces, making them perfect casings for the lens. Using the patient's own tooth also prevents rejection by the body's immune system. After approximately 50 previous failed procedures, Chapman finally made successful eye contact with his doctor, bringing both men to tears. He now looks forward to spending time with family and traveling.
