LASIK (Laser-Assisted In Situ Keratomileusis) is a popular and effective surgical procedure used to correct common vision problems such as nearsightedness, farsightedness, and astigmatism.

During LASIK surgery, a special laser is used to reshape the cornea, which is the clear front part of the eye, to improve the way light is focused on the retina, resulting in improved vision. The procedure is usually performed as an outpatient procedure under local anesthesia, and typically takes less than 30 minutes to complete.

Here are some key steps involved in LASIK surgery:

1. Preparation: Before the surgery, your eye surgeon will perform a thorough eye examination to assess your eye health and determine whether you are a good candidate for LASIK. You will also be given instructions on how to prepare for the procedure, which may include avoiding contact lenses and eye makeup for a period of time before the surgery.
2. Anesthetic: The surgeon will use anesthetic drops to numb the eyes and make the procedure more comfortable.
3. Cornea Reshaping: The surgeon will create a thin flap on the cornea using a microkeratome or a femtosecond laser. The flap is then folded back, and a laser is used to reshape the cornea. The amount of cornea tissue removed is determined by the specific vision problem being corrected.
4. Flap Replacement: After the cornea has been reshaped, the flap is carefully repositioned onto the cornea without the need for stitches.
5. Recovery: After the procedure, your eyes may feel dry and scratchy for a few days. You may also experience some blurriness or hazy vision, which should improve over time as the eyes heal. Your surgeon will provide specific instructions on how to care for your eyes after the surgery, including the use of eye drops and avoiding certain activities such as swimming or heavy lifting.

LASIK is generally considered a safe and effective procedure, but it’s important to discuss the potential risks and benefits with your eye doctor before deciding whether it’s right for you.
