If the cancer is in your eye socket, the surgeon may have to remove your eye (orbital exenteration), which will lead to vision changes.
The empty eye socket will be replaced by a sphere of tissue from another part of your body. This keeps the structure of the eye socket.
Later you can be fitted for an artificial eye, which is painted to look like your remaining eye. The eye is like a large contact lens that fits over the new tissue in the eye socket. You will still be able to see with your remaining eye, but your depth perception and peripheral vision will be poorer. Your changed vision should not prevent you from continuing activities such as driving or playing sport, but it may take time to get used to these changes.
