Contact lenses and glasses: They correct common eye problems like nearsightedness, farsightedness, and astigmatism.
LASIK (laser-assisted in-situ keratomileusis): A doctor creates a thin flap in your cornea and then uses a laser to reshape it. This procedure improves nearsightedness, excessive farsightedness, and astigmatism.
Photorefractive keratectomy (PRK): The doctor rubs surface cells off your cornea, then uses a laser to improve nearsightedness, farsightedness, or astigmatism. The cells grow back and your eye heals the same way it would if you'd scratched it.
Artificial tears: These eye drops are a lot like your natural tears. They can help treat dry or irritated eyes.
Cataract surgery: The doctor removes the cloudy cataract and replaces your natural lens with a man-made version.
