<unk>  or<unk>  (laser-assisted in situ keratomileusis), commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hyperopia, and an actual cure for astigmatism, since it is in the cornea.<unk>  surgery is performed by an ophthalmologist who uses a laser or microkeratome to reshape the eye's cornea in order to improve visual acuity. For most people,<unk>  provides a long-lasting alternative to eyeglasses or contact lenses.<unk>  is most similar to another surgical corrective procedure, photorefractive keratectomy (PRK), and<unk> . All represent advances over radial keratotomy in the surgical treatment of refractive errors of vision. For patients with moderate to high myopia or thin corneas which cannot be treated with<unk>  and PRK, the phakic intraocular lens is an alternative. As of 2018, roughly 9.5 million Americans have had<unk>  and, globally, between 1991 and 2016, more than 40 million procedures were performed. However, the procedure seems to be a declining option for many in recent years.
