What is LASIK (laser in-situ keratomileusis)

What is LASIK (laser in-situ keratomileusis)

LASIK (laser in-situ keratomileusis) is eye surgery which corrects myopia or nearsightedness, farsightedness and astigmatism. LASIK stands for Laser-Assisted In-Situ Keratomileusis (vision correction laser surgery). LASIK eye surgery is corrective eye surgery in which laser is used. A flap of the corneal surface is lifted and a thin layer of underlying tissue is removed.
Myopia or nearsightedness, farsightedness and astigmatism are often caused because of focusing errors that can be corrected or treated by changing shape of the cornea. Eye cornea football-shaped causes astigmatism more steep shape causes nearsightedness and too flat shape causes farsightedness. LASIK surgeon reshapes cornea and uses a laser to remove microscopic cells in the layer under flap of corneal surface. After few minutes, the surgeon completes his work and puts the flap back in place which works like bandage as patient’s eyes repair. After LASIK eye surgery patient sees with improved vision.
