Implanted tooth helps blind US woman recover sight

A 60-year-old US grandmother, blind for nearly a decade, has recovered her sight after surgeons implanted a tooth in her eye as a base to hold a tiny plastic lens, her doctors said Wednesday.

In the procedure -- which was pioneered in Italy but was a first in the United States -- the medical team extracted Thornton's canine or "eyetooth" and surrounding bone, shaved and sculpted it, and drilled a hole into it to insert an optical cylinder lens.

She was able to recognize objects and faces a few hours later, and 15 days later she was able to read newspapers, the Eye Institute said.
