Most cases of astigmatism are only due to the bad shape of the cornea. So can night-time contact lenses have a permanent effect on cornea reshapening?

"Night-time contact lenses: During sleep, special gas-permeable contact lenses exert gentle pressure on the outer layer of cells in the cornea, reshaping its surface. The next morning, the eye has a different refractive value, so that wearers can see clearly during the day without glasses or ordinary contact lenses."


But even if these contact lenses are gas-permeable they are not 100% and very good hygiene rules must be taken in order not to get infected.
