Laser eye surgery, or LASIK, is a popular surgery that helps correct vision in people who are nearsighted, farsighted, or astigmatism.

It is one of the vision correction surgeries, which works by reshaping your cornea, so that light focuses on the retina in the back of your eye, according to WebMD.

Doctors often indicate laser eye surgery to people with refractive errors, such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism (blurry vision).

Many celebrities had these vision problems and wearing eyeglasses or contacts in their daily lives was not feasible to them. However, they eventually went on to get laser eye surgery.

Here are some of the world’s biggest celebrities who had undergone laser eye surgery:
