Bad idea. These things have been around since the 1960's and they've never worked well long term- and sometimes cause permanent eye damage.

They work by being harder or a different shape than your own cornea to mold it into a new shape. Then, the cornea is supposed to stay that way. Problem is, the cornea doesn't like this and tries to resume it's own shape naturally so that the vision becomes unstable- sometimes taking 6 months to come back to normal, during which time the vision is different in the morning than the afternoon, than the evening. In some cases the cornea responds by causing scarring that causes blindness that can only be corrected by corneal transplantation. That's where I come in. I do the surgery. It's expensive and takes about a year to recover from.

The worst that can happen is that the cornea doesn't get enough oxygen at night through the lens and closed eyelid, becomes swollen and painful, gets infected, and the eye is lost.
