History
  • Dr. Steven Trokel introduced Photorefractive
    Keratectomy (PRK). He also patented the Excimer
    laser for vision correction and performed the
    first laser surgery on a patient's eyes in 1987.
  • In 1996, the first Excimer laser for ophthalmic
    refractive use was approved in the United States.

4
What is Laser Surgery For Eyes ?
  • LASIK is a surgical procedure that uses a laser
    to correct near-sightedness, farsightedness,
    and/or astigmatism.
  • In LASIK, a thin flap in the cornea is created
    using either a microkeratome blade or a
    femtosecond laser.
  • The surgeon folds back the flap, then removes
    some corneal tissue underneath using an excimer
    laser.

5
How Is LASIK Surgery Performed
  • First, your eye surgeon uses either a mechanical
    surgical tool called a microkeratome or a
    femtosecond laser to create a thin, circular
    "flap" in the cornea.
  • The surgeon then folds back the hinged flap to
    access the underlying cornea (called the stroma)
    and removes some corneal tissue using an excimer
    laser.
  • For near-sighted people, the goal is to flatten
    the cornea with farsighted people, a steeper
    cornea is desired.
  • Laser eye surgery requires only topical
    anesthetic drops, and no bandages or stitches are
    required.

6
Advantage
  • The LASIK technique takes less than 30 minutes to
    perform and is very effective
  • The technical advancements incorporated in the
    LASIK technique eliminates the clinically
    significant risks leading to visual impairment
    after a refractive surgery.
  • Most surveys show that 92-98 of people who
    undergo the surgery are satisfied. With the
    results

7
Disadvantages
  • The LASIK surgery, done on the most sensitive
    part of the eye and is not reversible
  • Even after a LASIK surgery, a person may require
    reading glasses during midlife.
  • The surgery is usually not covered by insurance
    policies.
  • Additional surgery or ' enhancement' may be
    required to enjoy the best possible result of a
    LASIK.

8
Long-Term Results
  • Laser eye surgery offers numerous benefits and
    can dramatically improve your quality of life.
    Most people achieve 20/20 vision or better after
    the surgery, but LASIK results do vary. Some
    people may achieve only 20/40 vision or less.
  • You may still need to wear glasses or contact
    lenses following laser vision correction, though
    your prescription level typically will be much
    lower than before.
  • A small percentage of people will need a LASIK
    enhancement, or "touch up" procedure, a few
    months after the primary LASIK surgery to achieve
    acceptable visual acuity.
