The title "For the 1st time in Canada, surgeons put teeth in patients' eyes to restore sight" is much clearer than "Surgery aims to restore sight by implanting a telescopic lens in a tooth". First, the tooth is put into the eye — used as biocompatible material to hold the lens. Second, the surgery is 60 years old and has something like a 94% success rate after 27 years, so it's hardly fair to say "surgery _aims_ to restore sight". It almost certainly will restore sight. The part that is interesting in this story is that it's an uncommon surgery that is happening only for the first time _in Canada_.
