Laser in-situ keratomileusis (Lasik) is a surgical procedure that uses a laser to correct nearsightedness, farsightedness, and/or astigmatism. In Lasik, a thin flap in the cornea is created using either a microkeratome blade or a femtosecond laser. The surgeon folds back the flap, then removes some corneal tissue underneath using an excimer laser. The flap is then laid back in place, covering the area where the corneal tissue was removed.
With nearsighted people, the goal of Lasik is to flatten the too-steep cornea; with farsighted people, a steeper cornea is desired. Lasik can also correct astigmatism by smoothing an irregular cornea into a more normal shape.
Other procedures similar to lasik are SMILE eye surgery (which is the newest method of laser eye surgery) and femto-lasik (which also called bladeless lasik). Read about these surgeries to know which one might be the best option for you.
Before the procedures doctors will examine the eyes to check if they are healthy enough to do the surgery. Patients should care about the following actions before the due date:
Before procedure, medication will be given to some patients helping them to relax. Once patients are ready for the procedure, the eyes will be numbed with anesthetic eye drops. A device will be used to keep eyes open and to help surgeon to create a flap. As the surgeon creates the flap, a light pressure might be felt, but no pain.
Once the flap is created, the surgeon will adjust the excimer laser to your specific prescription. The patient will be asked to look at a target or spot, while the surgeon uses the laser to change the shape of the cornea. Laser treatment lasts for 10 to 90 seconds.
Many patients report being able to smell a faint burning smell during the procedure. Once the procedure is over, your vision will start to improve right away, and should become stable in 1 to 3 months.
Lasik is one of the most well-known and successful corrective eye surgery.
Some patients feel a temporary burning or itching sensation in the treated eye. Patients should expect that their vision will worsen in the first 24 hours after the procedure, and then improve significantly.
LASIK is eventually a pain-free procedure that recovers in 1 or 2 days. The eyes may be sensitive to light for couple of days till eyes are healed. There are some other post procedure recommendations to get the best result:
LASIK has a remarkable success rate, with 96% of patients achieving 20/20 vision or better, according to the American Society of Cataract and Refractive Surgery. Patients with more than 4 Di
