Laser-assisted in-situ keratomileusis

A surgical treatment for nearsightedness, farsightedness, and other refractive errors of vision. In this procedure, a microtome is used to cut a thin flap on the surface of the cornea and a laser is used to resculpt the deeper tissue and correct refractive errors. Many patients have a marked improvement in their visual acuity as a result of the procedure. Complications can include infections, hazy vision, double vision, visual halos, the need for reoperation, corneal burns requiring corneal transplant, and blindness.


A surgical technique, combining the use of a cutting tool and a laser, is employed to reshape the cornea and address moderate to high levels of myopia. This procedure, known as laser-assisted in situ keratomileusis (LASIK), involves the precise modification of the corneal tissue to correct refractive errors. By utilizing a cutting tool, a thin flap is created on the cornea, followed by the application of a laser to reshape the underlying tissue. This reshaping aims to improve the eye’s focusing power and reduce myopia, enabling patients to achieve clearer vision without the reliance on corrective lenses. LASIK surgery has proven to be an effective intervention for individuals with moderate to high levels of myopia seeking long-term vision correction.
