LASIK (short for Laser In-Situ Keratomileusis) is a widespread solution used to correct vision for patients with near- and far-sightedness and astigmatism. LASIK is a surgical procedure that uses an Excimer laser to reshape the corneal tissue so that light can be properly focused on the retina. LASIK is unique from other methods of eye surgery in that a flap is made in the cornea in order to access and repair the underlying tissue.
Like other forms of refractive laser eye surgery, LASIK uses a laser to reshape the cornea so in order to properly focus the light that travels through it onto the retina.
What to expect before a LASIK surgery:
Before surgery, a LASIK surgeon will generally recommend removing soft contact lenses for one to three weeks to prepare for the surgery. The surgeon will also use a laser to take a topographic map of the cornea in order to detect irregularities and astigmatism. This information is used to plan and prepare for the procedure.
Patients are required to stay conscious and alert during the procedure, but some sedatives such as aesthetic eye drops and valium are generally given.
In the weeks following surgery, the patient will be given eye drops to prevent infection and inflammation, and instructions are giving for proper care and recovery.
Approved by the FDA in 1989, a trial version of the Excimer laser known as PRK was used, and by 1992 LASIK was introduced and used in 10 centers in the US LASIK is now considered to be a very safe and reliable form of corrective eye surgery and millions of treatments are performed every year in the US
