my cato is getting old

my poor cato is really becoming an old man :(
he now has a cream i have to put in his eyes 2x's a day for the rest of his life due to cataracts and KCS (which is also called Dry Eye and is caused by destruction of the tear glands by your dog's own immune system. This means that too few natural tears are produced. Damage to the tear glands is irreversible. If left untreated, eventually the tear glands are completely destroyed and your dog loses the ability to produce tears. Dry Eye is a painful condition, and ultimately leads to permanent blindness.) There was one more thing she said by it's has escaped my mind at this point, but basically from where his eyes have gotten so dry and his eyelids have scratched them just by blinking that the blood vessels have started to grow over his whole eyes to try to repair the scratches.
besides his eyes though he is in awesome health for his age :)
