What Is LASIK?
Laser-assisted in situ keratomileusis (LASIK) is a common surgery that corrects refractive errors like myopia, hyperopia, astigmatism, and presbyopia.
During the LASIK procedure, the ophthalmologist creates a small flap in the cornea using either a specialized blade or cutting laser. The flap is lifted out of the way, and a computer-guided laser removes precise amounts of tissue from the inside layers of the cornea.
What Is PRK?
Photo-refractive keratectomy is another common laser refractive surgery performed in Canada to correct several refractive errors.
During the PRK procedure, the ophthalmologist removes the cornea’s outer layer with a surgical blade or blunt instrument. Tiny, precise tissue amounts are vaporized using a computer-guided laser to reshape the cornea and correct your vision.
What Is CLE?
CLE replaces your eye’s natural lens with an artificial lens in your required prescription. CLE is traditionally performed during cataract surgery, but it’s becoming more popular for correcting refractive errors in patients who aren’t candidates for laser eye surgery.
During the CLE procedure, your natural lens will either be removed by breaking it up with an ultrasound probe or creating an incision to remove the lens in one piece. Once the lens is removed, the artificial lens is placed in the empty lens capsule.
