- A Canadian man, Brent Chapman, has regained his eyesight after 20 years thanks to a rare and complex "tooth-in-eye" surgery.
- Mr Chapman, 34, lost his vision at the age of 13 due to Stevens-Johnson Syndrome, a severe allergic reaction to ibuprofen.
- The procedure, known as osteo-odonto-keratoprosthesis, involves extracting a tooth, inserting an optical lens, and then implanting this "tooth-lens" into the eye.
- Performed by ophthalmologist Dr Greg Moloney, the surgery was carried out in two stages between February and August, with the final adjustment in August.
- Mr Chapman now has 20/30 vision, and his first sight after the surgery was the Vancouver skyline, an experience he described as "surreal and euphoric".
