I'd do that in a heartbeat if it corrected astigmatism. I'm sure it's a
lot less painful than the PRK I've been relegated to, plus it's reversible.

Check your eyelids. If you have heavy eyelids, the pressure from them can
slightly deform the cornea and produce refraction errors that manifest as
astigmatism. If this is the cause, minor plastic surgery on the eyelids can
reduce their pressure on the cornea and correct the error. Monocular
diplopias can be caused in this way.
