Looking for contacts after RK

    I had RK 20 years ago to correct myopia. I guess I have those kind of
    eyes that just keep going, and going, and going because now I am very
    farsighted and wear a strong reading pescription. I have progressive
    lenses now and they are not too bad because my reading prescription is
    pretty close to my distance.
    I have been thinking of contacts. Maybe distance in one eye, reading
    in the other. I am

    R +3.50, -.75, 100 (dominant)
    L +4.75, 1.00, 067
    +2.25 add

    Any contacts need to be able to work with me falling asleep in front
    of the TV at night. My most eye-strenuous needs are a computer screen
    and golf. I don't want to spend to much in case it doesn't work out,
    maybe pick up something on the internet, but I recognize from reading
    this group that cheap contacts over RK can be pretty tricky. My
    reading eyes have been pretty stable for the last few years.
    If I can get a specific brand recommendation I could shop doctors or
    go sreaight to the internet because my Dr. has a limited selection.
    Any suggestions?

    This is a long and complicated subject. The majority of post-RK patients I
    have worked with have required custom-designed rigid gas-permeable lenses
    to achieve the best vision. These lenses are able to correct not only the
    farsightedness, but also the irregular astigmatism that often occurs as a
    result of RK. These lenses and the time it takes to fit them will require
    an investment of time and money.

    On the other hand, some post-RK patients have done quite well in soft
    lenses. You have a borderline amount of astigmatism for a conventional
    soft lens, and you may need a toric lens to correct the astigmatism. You
    would need to go for a trial fitting first to find out. Also, post-RK
    corneas are more sensitive to oxygen deprivation and very easily grow blood
    vessels that follow the RK incisions. And, since you like to sleep in your
    lenses, they should have the highest possible oxygen permeability. The
    soft lenses that fit this criterion are the Focus Night and Day, the Acuvue
    Advance(not FDA approved for overnight wear), and Purevision(available
    outside the U.S. at present). None of these lenses are available in toric
    versions for the correction of astigmatism.

    You cannot purchase lenses on the internet without a prescription, and you
    cannot get a prescription without seeing a doctor for a trial fitting. As
    I said, this is a complicated subject.

    Sadly you can purchase lenses on the internet without a prescription DrG.
    Outside the US everything is possible.

    Sorry, my mistake. And here I thought that the U.S. was less regulatory.
    Perhaps it would be more correct to say that it would be foolish to self-

    Ok. I see the acuvue advance is cheap enough to give it a go. I'll
    try one eye reading, one eye distance. Can you advise on how to
    convert my reading prescription to a mono lens?
    If this doesn't all doesn't work out, can I get a recommendation for a
    lens to be fitted by the Dr? I have been looking at the C&H Macrolens
    and the Menicon but there aren't many places in town that handle them.

    Thanks all for your advice

  6. The best advice given should be : visit an eyecareprofessional who is
    familiar with and known for his or her skill on fitting contactlenses.
    You may ask the specialist you are visiting about his skill in fitting hard

    Keep in mind, fitting contactlenses is NOT possible without having a
    client/patient " face à face" in front of you.
    I.e , to find out which eye is to be used as the "far distance" one, it is
    not simply take the dominant eye (one of the more simple decisions that has
    to be made).

    Paying peanuts getting .......?

    BTW, this advise is for free but not a primate Otis.

    I am not advising you to prescribe for yourself, but the definition of an
    "add" is something that is added, i.e. in this case added to the distance
    prescription. So, a person with a -2.00 distance and +2.00 add would
    require a plano lens for reading.

    I fit the Macrolens, but I have them customized for the unusual shape of
    the post-RK cornea. They are difficult or next to impossible to fit
    without a good set of trial lenses.

    Menicon is just a manufacturer. Years ago they had a product called the
    Plateau lens. It was the first lens to be advertised for post-refractive
    surgery. The Plateau lens was just their version of a large, reverse
    geometry RGP lens. This is a sub-specialty where experience can mean the
    difference between success and failure.

    Then again, I don't really know your personal criterion for success.

    Indeed I advised you instead of answering, so did others.
    Keeping people out of trouble.
    Not at all, since this newsgroup is called sci.med.vision and not
    Eyecare professionals are paid for such, are you not?
    You'r wellcome

  9. Indeed DrG is more kind and friendly as is the Dutch guy.
    The advise given by DrG is not that direct as mine (the Dutch are famous for
    being direct) Puttster, but in the end he says the same.
