WHICH WOULD REDEFINE EYE TEETH (via Jim Yates):

Tooth used to save woman's sight (BBC, 8/18/04)

A blind woman can see again thanks to UK surgeons who used her own teeth to restore her vision. [...]

It is an option for people with corneal blindness which has not been amenable to conventional eye surgery.

The surgery takes part in two stages, each taking around six hours and carried out about six months apart.

Two surgeons, an eye surgeon and a maxillo-facial surgeon, work together to repair the damaged eye.

During the first stage, the superficial scar tissue over the damaged cornea is removed and the whole surface is then covered with a patch of tissue taken from the inside of the patient's cheek.

This will create a new surface for the eye.

The surgeons then remove one of the patient's teeth, usually a canine, together with a small block of jawbone.

This is used to fashion a rectangular plate with a hole drilled through the middle.

A small synthetic tube is inserted into this hole and the whole thing, now called an OOKP lamina, is placed under the muscle of the lower eyelid for two to four months to allow surrounding tissue to grow into the substance of this implant.

During the second stage, the cheek tissue covering the eye's surface is raised and a hole is made through the centre of the scarred cornea.

The surgeons then remove the iris, the lens and the jelly of the eye that lie behind the cornea.

They extract the OOKP lamina that they had implanted and then insert it into the hole they have made in the cornea and sew it firmly in place.

The cheek tissue is lowered back down to cover the eye again.

About 80% of people who have this surgery achieve an improvement of their vision, according to he eye surgeon who carried out the procedure, Mr Christopher Liu.


Of course, it's not easy flossing your eyelashes...

Only in America, well in this case the U.K. could anything like this be even imagined nevermind become routine.

Good going doc.

I heard on Al-Jazzeera today that this procedure was first used by Muhammed in the city of Mecca when . . .

Oh, that's right - no decent medical discoveries have ever emanated from that part of the world since the rise of Islam, with the exception of decapitations.

This gives a whole new meaning to "An eye for an eye and a tooth for a tooth."
