Sharron Thornton, who was blind for nine years as a result of a disorder known as Stevens-Johnson syndrome that damaged her corneas, was able to recover her sight after she underwent a rare surgery that transplanted her own tooth into her eye, a procedure called modified osteo-odonto-keratoprosthesis (MOOKP). It had seemed before that there was no hope for Thornton in regaining her eyesight, but thankfully, one of her doctors had previously heard of a surgery in which an artificial cornea could be constructed using a tooth as the scaffold.
