What's the difference between lasik and cataract surgeries?

There are two main types of vision correction surgery: LASIK and cataract surgery. Lasik surgery corrects refractive errors, such as nearsightedness, farsightedness, and astigmatism. Cataract surgery removes the cloudy lens that causes vision problems. While both types of surgery can improve your vision, they are different procedures. Lasik involves modifying the shape of your cornea with a laser to change the way light enters your eye. Cataract surgery replaces your cloudy natural lens with an artificial one.
