Final answer:
LASIK surgery can correct refractive problems such as myopia, hyperopia, and astigmatism by permanently changing the shape of the cornea.
Step-by-step explanation:
LASIK surgery is a procedure that uses a laser to reshape the cornea of the eye, which can correct refractive problems such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. It permanently changes the shape of the cornea so that light is correctly focused on the retina, resulting in improved vision.
However, LASIK surgery may not be suitable for all types of refractive problems or individuals. It is important to consult with an eye care professional to determine if LASIK surgery is the appropriate treatment option.
