It involves removing a patient's tooth, usually the canine, installing a plastic optical lens inside it, and then implanting the whole thing into the eye.
You're viewing a single thread.
I was involved in some research making implants using in part, patients own hair as a support matrix, and I made the 'mistake' or misconception that I think may also be here. That being the concept of it being the 'patients own tissues', and therefore better. However for these more inert tissue types there is no advantage, and you have the disadvantage of not selecting an inert material that might be have more optimal properties, and doesn't require harvesting. So in this example, an artifical bone material, if implanted in the same fashion, would respond in the same way. The notion of it coming from a patients own tooth enamel, might give a 'feel good factor', but in histological terms, does not have the biological advantage you might think it has.
