Laser eye correction surgery has been used for decades to correct astigmatism.

Astigmatism occurs due to an irregular curvature of the cornea resulting in a blurry image
This causes images to appear blurred or even show “ghost imaging”. Half of people suffering from myopia or hyperopia also suffer from astigmatism.

Laser eye surgery can correct astigmatism, whether there is also some residual myopia or hyperopia or not.
