How A Tooth in the Eye Is Giving Blind People Sight
hold out hope: to continue believing that something good might happen, even when it seems unlikely
For the first time in Canada, surgeons are using a patient’s own tooth to restore eyesight. The operation, called “tooth-in-eye” surgery, has been done in other countries for decades and has a 94% success rate.
Doctors take a small piece of the patient’s tooth and place a tiny lens inside it. They then insert it in their cheek so tissue can grow around it. Later, they move it into the eye, allowing light to pass through the lens and restore vision. Since the tooth comes from the patient’s own body, there is no risk of rejection.
Brent Chapman had been blind for 20 years. He tried many different treatments over the years. Some of them would restore his vision for a short time, but then he would go blind again. Despite these failures, he holds out hope that this tooth-in-eye surgery will permanently restore his vision. This week, he will become one of just three Canadians to have this unique treatment.
