is my Slab-off prescription necessary

    I am 51, had lasik about 5 years ago correcting to 20/20 in both eyes.
    Was quite nearsighted before that. Last month I had a detached retina
    in my right eye, had surgery, had the buckle put around my eye and I'm
    recovering well. Can read quite well at about 14" now, but distance is
    what needs to be corrected the most. Doctor says my eye will continue
    to improve a bit over the next few months.

    My pupil is still a bit dilated. I went to my eye doctor the other day
    to get a new lens prescription. The reading on my eyes is:
    Sphere Cyl. Axs VA Far Add
    R:-2.50 -0.25 100\ 20/30 2.25
    L:+0.75 -0.25 100\ 20/20 2.25

    Notes: Slab Off

    When I took this prescription to Costco I was told they don't do Slab
    Offs. I went elsewhere and they charge $130 just for the Slab Off
    portion. Ouch, no insurance. So I hesitated, thinking I'd learn a bit
    more about this - especially if it means every pair of glasses I get
    for the rest of my life will need to include this expensive slab off.

    As I read up on internet, it appears that I need it to help prevent
    double vision if the difference in diopters is greater than 2 between
    the two eyes. I guess mine is greater than 3 if I interpret the above

    But when I take my present glasses and tilt them so the left eye is
    looking thru the magnified area where it usually reads, and the right
    eye is looking more thru the clear, less magnified, area of the lens
    (I can now read quite well without correction if page is 14" away), I
    don't have any double vision problems. The letters on the page appear
    as one. Also, if I close one eye and then the other, the letters
    appear to be the same size.

    So my question is, do I really nead the Slab-off procedure as part of
    my prescription? Is my "tilting the glasses" test at all valid? I
    really don't want to always get the Slab Off on all future glasses if
    I don't need it.

    Anyone who has any experience with this, I'd sure like to hear from
    you. Also, are my eyes likely to improve sufficiently over the next
    months to where I wouldn't need the Slab off? The right eye is at
    20/30 now, I'm a commercial pilot and praying it comes back to the
    required 20/20!!!

    Thanks for any input.

  2. You went for your broken tire to fix it, they changed the whole car
    giving you an old rotten bycicle.

    Now what do you expect?
