Vision problems such as nearsightedness, farsightedness, and astigmatism can be treated by a surgical procedure known as LASIK, or laser eye surgery. According to the American Academy of Opthalmology, laser eye surgery involves the use of a laser to reshape the cornea in the front of the eye.

Eye surgery, while once a tricky procedure that required working with microscopic structures, is now performed on a regular basis. Eye surgery ranges from corrective procedures to vision-saving surgeries that correct cataracts, glaucoma or eye tumors.
