Use artificial cornea to restore vision

Canadian scientists have used artificial corneas to successfully restore sight to some patients, thereby helping them avoid the risk of blindness.

The therapeutic effect of these patients is similar to the effectiveness in treating patients with corneal donation.

Cornea is especially important for vision. The birth of an artificial cornea is of great significance to complement the scarcity of the cornea and meet the needs of patients.

First, the scientists created thin and button-shaped lenses from the cornea made of colloid colloids. Ten patients with corneal disease have undergone surgery to remove damaged organizations outside the eye and replace them with new artificial corneas.

This artificial corneal transplant patient may have the same vision as a corneal transplant patient from donors. In addition, this artificial cornea can avoid the risk of infectious diseases in people who donate corneas and the elimination phenomenon caused.

Corneal lesions can have many causes including genetic factors, surgical injuries, burns, infections and cancer chemotherapy lesions. Every year the world has about 1.5 million blind people because they are not given corneas.
