LASIK surgery reshapes the cornea by ablating corneal tissue using a laser to correct its shape.

“basically the way the lasic does that is it actually ablates or uh uh gets rid of a little ring or rim of that corn tissue so that for example if you were a little shallow and you got rid of a little bit of that tissue around the edge with the laser the Las lasic you know starts with the word laser if you got rid of that edge tissue then you're sort of making it a little more basketball shaped right or if you were too steep on your cornea and you use the laser to kind of shave off a little bit of the the tip of that basketball right then you're flattening it out flattening out the cornea”
