What happens after laser eye surgery?

Depends on goal. Laser may be used to change the refractive power of the eye (lasik or prk), treat glaucoma (alt) , treat angle closure glaucoma (peripheral iridotomy), treat aberrant blood vessels in the back of the eye (prpc, focal laser treatment), or tumors of the back of the eye. What happens after is improvement in the treated condition, and sometimes a cure.
