LASIK or Lasik (/ ˈ l eɪ s ɪ k /; "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 astigmatism. [1]
Photorefractive keratectomy (PRK) and laser-assisted sub-epithelial keratectomy (or laser epithelial keratomileusis [1]) (LASEK) are laser eye surgery procedures intended to correct a person's vision, reducing dependency on glasses or contact lenses.
Recovery time is longer with PRK than with LASIK, though the outcome (after 3 months) is about the same (very good). More recently, customized ablation has been performed with LASIK, LASEK, and PRK. Transepithelial photorefractive keratectomy (TransPRK) is a laser-assisted eye surgery to correct refraction errors of human eye corneas. It uses ...
Laser Blended Vision can be achieved through laser eye surgery, usually performed as LASIK, although surface laser eye surgery PRK or LASEK can be used to produce the effect. Laser Blended Vision works by increasing the depth of field of each eye through subtle changes in the optics of the corneal spherical aberration. [2]
Eye surgery, also known as ophthalmic surgery or ocular surgery, is surgery performed on the eye or its adnexa. [1] Eye surgery is part of ophthalmology and is performed by an ophthalmologist or eye surgeon. The eye is a fragile organ, and requires due care before, during, and after a surgical procedure to minimize or prevent further damage.
Their vision can still be restored with Epi-LASIK, photorefractive keratectomy, LASIK or phakic lens extraction, or cataract surgery. The corneal curvature has to remeasured and modified by history, central keratometry , or contact lens method.
