LASIK (Laser-Assisted In Situ Keratomileusis) is a type of refractive eye surgery that is used to correct vision problems such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. The surgery involves using a laser to reshape the cornea, the clear front part of the eye, in order to improve the way light enters the eye and focuses on the retina, which helps to improve vision.

During the LASIK procedure, the surgeon first creates a thin, hinged flap in the cornea using a blade or laser. The flap is then lifted and the laser is used to reshape the cornea. The surgeon will use a computer-controlled laser to remove precise amounts of corneal tissue based on the patient’s individual prescription.

After the cornea has been reshaped, the surgeon will reposition the corneal flap, which will naturally adhere to the underlying tissue without the need for stitches. The entire procedure usually takes less than 30 minutes and is performed under local anesthesia.

LASIK surgery is typically an outpatient procedure and patients can usually return to their normal activities within a day or two. The success rate of LASIK surgery is high, and most people who undergo the procedure achieve improved vision without the need for corrective eyewear. However, as with any surgical procedure, there are risks and potential complications, and it’s important to discuss these with your eye doctor before deciding whether LASIK is right for you.
