How Does LASIK Surgery Work?

H2: How Does LASIK Surgery Work?

1. What is LASIK Surgery?

LASIK (Laser-Assisted in Situ Keratomileusis) is a type of refractive surgery that aims to improve vision by reshaping the cornea. During the surgery, a laser is used to remove some of the corneal tissue to alter the way light enters the eye, correcting refractive errors such as nearsightedness, farsightedness, and astigmatism.

2. How is the procedure performed?

To perform LASIK surgery, a surgeon first creates a protective flap on the outer layer of the cornea using a precise, computer-controlled instrument. This flap is folded back to expose the underlying corneal tissue, which the surgeon then reshapes with a laser. The laser's intensity and duration are carefully controlled, allowing the surgeon to reshape the cornea so that light entering the eye is properly focused onto the retina.

After the cornea has been reshaped, the surgeon replaces the protective flap over the treated area and allows it to heal naturally. Because the flap adheres to the eye, no stitches are required. The entire procedure is relatively quick and usually lasts less than 30 minutes.

3. What are the benefits of LASIK Surgery?

LASIK surgery can improve visual acuity and reduce dependence on glasses or contact lenses. Most patients experience improved vision within a few days of the surgery, and the results are typically long-lasting.

4. What are the risks and side effects of LASIK Surgery?

As with any medical procedure, there are risks associated with LASIK surgery, although they are rare. Possible complications include infection, dry eyes, glare, halos, double vision, and slight vision loss. However, most patients experience few or no side effects and are able to resume normal activities soon after the procedure.

H3: Conclusion.

In conclusion, LASIK surgery is a safe and effective way to improve vision and reduce dependence on glasses or contact lenses. By reshaping the cornea with a laser, the procedure corrects refractive errors and allows for properly focused light to enter the eye. Although there are risks associated with the surgery, they are rare and most patients experience few or no side effects. If you are interested in LASIK surgery, talk with your eye doctor to determine if you are a good candidate and to discuss the potential benefits and risks.
