Yes, her surgeon should have explained all this to her. She still can leave her second eye nearsighted and she hopefully will be happy with that.

Apparently, your aunt was nearsighted before surgery, and now she has good uncorrected distance vision. But she will need glasses for cooking, using the computer, and reading. This should have been explained to her before surgery.
Tell your aunt to make sure that her surgeon leaves her second eye a little nearsighted. Then she should be able to cook, put on makeup, and use the computer without glasses. If all goes well, she will only need glasses for reading small print.
