Laser Eye Surgery: A Quick and Painless Alternative to Wearing Spectacles
Laser eye surgery is a form of refractive surgery performed to correct hyperopia , astigmatism, and myopia. These are spectacle errors found in people with uncorrected or impaired vision. By 2011, more than 11 million patients had undergone laser eye surgery in the U.S.; by 2009, over 28 million surgeries had been performed globally. An ophthalmologist performs laser eye surgery using a microkeratome or laser to reshape the cornea and improve the patient's visual acuity. Most patients who undergo the procedure receive a permanent alternative to wearing contact lenses or eyeglasses. The procedure involves three main steps where: The ophthalmologist creates a lean flap in the cornea’s surface layer and sets it on the side. They’ll then reshape the bare area using precisely targeted laser pulses. The laser is guided by sophisticated algorithms to remove tiny corneal tissue amounts from various positions of the cornea that were pre-determined. This will correct the overall curv...
