LASIK is a surgical procedure intended to reduce a person's dependency on glasses or contact lenses. After the laser reshapes the cornea, the flap is then laid back in place, covering the area where the corneal tissue was removed. Then the cornea is allowed to heal naturally. Laser eye surgery like Femtosecond Laser Assisted Cataract Surgery requires only topical anaesthetic drops, and no bandages or stitches are required. There are many issues which can be treated with the laser eye operation.
Farsightedness can be treated with laser eye operation. Eye Doctors make the cornea steeper by removing tissue outside of the central zone of the cornea. This shifts the point of focus from beyond the retina to directly on the retina. To treat nearsightedness, tissue is removed from the central zone of the cornea. This shifts the point of focus from in front of the retina to directly on the retina. Often nearsightedness or farsightedness is accompanied by astigmatism, which can be treated simultaneously by making the cornea more spherical. Excimer lasers also can correct astigmatism by smoothing an irregular cornea into a more normal shape. It is a misconception that LASIK cannot treat astigmatism.
