1 is obviously non universal. You don't "lose" anything, but the nature of a lens is that it becomes harder, though completely possible, to focus up close afterwards, unless you're old and already can't with glasses.
You can test yourself to see what would happen. Wearing your nearsighted glasses, can you still read a book? You'll notice it is harder than without them. If so, then you still can after LASIK.
