Is LASIK eye surgery reversible?
LASIK eye surgery is a permanent vision correction procedure and is amongst the most popular types of refractive laser eye surgery available today.
It is a procedure in which a laser is used to cut a thin flap of tissue from the front of the cornea, the transparent anterior portion on the outer covering of the eye. Corneal tissue beneath the flap is vaporized by the laser to create a different shape that will correct the refractive error. The flap of tissue is then pulled back over the front of the eye. LASIK surgery can be performed in order to correct myopia (near-sightedness), hyperopia (far-sightedness), presbyopia, and astigmatism.
LASIK stands for Laser-Assisted in Situ Keratomileusis.
While this surgical procedure is irreversible, a laser surgeon is able to make additional corrections to the original treatment if needed. LASIK eye surgery has a high success rate with nearly 80 percent of successful vision corrections in patients who undergo the procedure. While LASIK surgery is relatively quick and painless, there are potential complications, as with any type of surgery.
Refractive eye surgery offers accepted candidates the chance of improved vision without the need for glasses or contact lenses.
Patients who have laser eye surgery have a high chance of achieving 20/25 vision or better. More than 8 out of every 10 patients who undergo LASIK surgery no longer require the use of glasses or contact lenses for the majority of their daily activities. Each patient’s specific results will depend on several factors. Patients with mild near-sightedness tend to have the most success with refractive surgery.
The best candidates for LASIK eye surgery are people who have never had a prior eye surgery.
Patients with healthy eyes and are looking to correct myopia, hyperopia, presbyopia, or astigmatism, are typically great candidates for laser eye surgery. Candidates must also have had stable vision for at least a year prior to the procedure. Those who take certain medications or have medical conditions may not be eligible for laser surgeries.
Lasik surgery is an outpatient procedure that usually takes less than 30 minutes to complete.
After the procedure, the eyes may itch, burn, water, or feel irritated. In addition, patients may experience haloes around lights or general sensitivity. These symptoms should fade within the first few days post-surgery. LASIK eye surgery patients should see a physician within the first 24 to 48 hours after surgery. At this postoperative visit, the physician should remove the eye shields, examine the eyes, and test the patient’s vision. During the first few months after LASIK surgery, vision may fluctuate. It can take between 3 and 6 months for vision to completely stabilize after surgery.
