in myopia , your eye balls is longer than usual so things are out of focus. but mypoia is generally stable .
keratoconus is weakeness of the cornea of the eye ..and the cornea being thin bulges and becomes irregular. ...the cornea is the clear window that you see outermost in the eye...... or rather , becoz it is transparent ..you don't see !
the problem with keratoconus is that it may progress. it behaves differently in people . in most in progresses and then stops ...but in some it goes on progressing.
many can be corected with contact lenses , but some will need a corneal transplant.
