    The range of pathologies which can be treated with Laser Eye Surgery

    * Myopia (nearsightedness): -0.75 diopters to -10.0 diopters
    * Hyperopia (farsightedness): +0.75 diopters to +5.0 diopters
    * Astigmatism (associated with myopia): 0 to 4.0 diopters
    * Presbyopia (the eye's diminished ability to focus that occurs
    with aging).

    Traditionally, many of these conditions were often treated with
    prescription glasses or contact lenses. Today, a number of innovative
    Laser Eye Surgery procedures are widely available.
    There are three main types of Laser Eye Surgery:

    PRK (Photo Refractive Keratectomy) has been the standard eye laser
    surgery for many years.
    It involves the complete removal of the epithelium or the outer layer
    of cells on the eye, with the use of a "cold" laser light.
    PRK is mostly used on patients with low to moderate amounts of Myopia
    Below you can watch a video showing a PRK surgical intervention:

    LASEK (Laser Assisted Sub-Epithelial Keratectomy) or EPIFLAP (Laser
    Assisted Epithelial Keratomileusis) surgery involves the fractional
    removal of the epithelium to reveal the cornea, which is then firmed
    or reshaped by a laser. The outer layer of cells is then pushed back,
    and the eye heals shortly after.
    LASEK is used on patients with low to moderate amounts of Myopia or
    Below you can watch a video showing a LASEK surgical intervention:

    LASIK (Laser Assisted in Situ Keratomileusis) is the newest and most
    popular type of eye laser surgery. Initially developed by Spanish
    ophthalmologist José Barraquer, with this procedure a thin layer of
    the eye's cornea is sliced off to create a flap. This enables the
    laser to target the tissue underneath. The flap is simply replaced and
    grows back naturally. Vision is restored almost immediately.
    LASIK is usually used on patients with severe Myopia
    (nearsightedness): -0.75 diopters to 10.0 diopters.
    Below you can watch a video showing a LASIK surgical intervention:

    All of these treatments have been approved for use in many countries
    around the world and are therefore considered to be safe.
    But it must be taken into account that all types of surgery does
    involve risks and eye surgery is no different.
    There have been cases during which patients have suffered major
    complications and required cornea transplants following laser

    Not everyone can have laser eye surgery. Although eye laser surgery is
    usually suitable for healthy adults and can be performed on virtually
    any eye, sometimes it is not advisable.

    You've only described refractive laser surgeries -- there's a whole
    lot of other eye surgeries done with lasers, including the treatment
    of glaucoma (Selective Laser Trabeculoplasty, for example); the use of
    lasers in removing cataracts (laser phaco); the use of lasers to clear
    up cloudiness of the capsular tissue left behind when some IOLs are
    implanted; and of course lasers used to treat retinal diseases.

    I have written about all of the above, including laser refractive
    surgery on my web Journal.

    Go to http://irvaronsjournal.blogspot.com and type in "menu" in the
    search box at the left top to find articles/reports on all of the
    above type of laser surgeries.

    I believe it speaks for itself, no?

    Would you be so kind as to point to individual posts?

    The easiest way to see what's on the web site is to open the main page
    and then type "menu" into the search box in the upper left hand
    corner. I have 9 menus that will show up, listing the various
    postings, along with links to the individual pages.

    I have written extensively on refractive surgery, SLT for glaucoma,
    laser phaco for cataract removal, and on laser surgery on the retina
    for treating AMD.

    The "home" page is:


    Good luck.

    If you have any questions, please contact me via email -- the address
    is on the side bar of the blog.

    There is a better way for doing that with tags.
    I probably will in the future, Irv.
    Too busy right now.

    Take care.
