Contact Lense Prescription problem

    I recently went to the eye doctor and got a prescription for
    glasses and contact lenses. My first appointment, he gave me my
    glasses prescription which was:

    OD: Sphere -1.75
    OS: Sphere -2.00 Cylinder -1.00 Axis 172
    He gave me a trial pair of contacts to try out after this first
    appointment and said he would give me my contact prescription a week
    later when I came in. The contacts seemed fine that first week.

    I received my glasses and they worked perfectly. Then I went back
    the following week and the contact prescription he gave me read as

    OD: BC 8.60 Diameter 14.00 Sphere -1.75
    OS: BC 8.70 Diameter 14.00 Sphere -2.00 Cylinder -0.75 Axis 010

    I didn't have my glasses prescription in front of me when he gave me
    the contacts prescription so I didn't know to ask the difference in
    the axis as I ordered the lenses from his office. A week later I
    received the prescribed contacts and noticed that my OS(left eye), the
    one with astigmatism was not as sharp as my right eye and the left eye
    contact doesn't seem to fit as well as the right. It is as sharp as my
    right eye with my regular glasses. My question is, did he make a
    mistake changing the cylinder number and axis number when he gave me
    the contacts prescription? Any help would greatly be appreciated,
    thank you.

    The contact lens prescription is based on how the lens fits the eye,
    the actual measured over refraction and, in the case of torics, the
    axis is determined by the rotation of the lens on the eye. If you are
    not happy with the vision, return to the fitter. You should know that
    it is more difficult to get a toric (astigmatism correcting) lens to
    deliver good vision and not uncommon for the spherical lens to be
    clearer than the toric.

    sounds like the examination when entirely appropriately. that's
    exactly the same work flow that many optometrists use: examination
    concluding with dispensing trial contacts, and a follow-up appointment
    a short time latter to give you time to assess your vision and the
    comfort of the lenses. the exact figures he wrote on the prescription
    for contacts is quite reasonable. The left toric lens prescription
    also looks entirely reasonable for those types of lenses. Oftentimes
    they sit on the corneal slightly rotated as compared to the
    prescription measured during the exam on the phoropter-- adjusting the
    axis measurement on the contact lens to approximately 10 degrees would
    likely compensate for that rotation.

    fret not. all is well.

    Excuse , me please. are you OCD?


    [don't be afraid to search the archives Lena. Actual inquiry,
    exploration, investigation, and experimentation ARE a universal good
    thing ... EVEN WHEN they refute your closely-held beliefs.]
