10 Swedish patients in a two-year trial are now being helped to see again through biosynthetic corneas. These have been developed for more than ten years and was implanted in the eyes of these patients to help them recover their sight to see the light. This information was brought by the researchers in Sweden and Canada.

Ottawa Hospital Research Institute's senior author who is May Griffith stated that the study of biosynthetic corneas are crucial for it is the first to prove that an artificial cornea can help people see and precipitate regeneration. More research is also crucial to the development of this study for it will allow millions of people to see by transplanting a donated cornea in them.

A collagen that was molded to look like a cornea was developed by Griffith along with her colleagues. They were tested with ten patients who were suffering from the scarring of their central cornea. The person who did this with Griffith was Per Fagerholm at Linkoping University located in the country of Sweden.

A cornea is what lets light to enter the eyeball. If the cornea is scarred, it will not allow light to enter the eyeballs and causes blindness. This is the major cause of blindness throughout the world and to remedy it with an artificial cornea could help restore the sight of many blind people.

Each patient that went through the clinical trial had one eye implanted with an artificial cornea so that the damaged corneal tissue would not prevent them from seeing. For two years, cells and nerves from a patient combined and grew into the implant and did not suffer rejection since the corneas were donated to them.

Six out of ten patients who undergone the clinical trial had improvements with regard to their sight which is a promising number for the study.
