Non-Disposable soft contact lenses

    I have been wearing non-disposable soft contact lenses for almost
    10 years now (changing it every year or so).

    I went to a doctor recently to get new lenses. He persuaded me to try
    daily disposables. I tried two premier brands each for a period of a couple
    of weeks. But neither was as comfortable as my original non disposables.
    My non-disposables are so comfortable that I practically don't feel them at all.

    However with the daily disposables, I felt they were pinching my eyes.
    The doctor examined my eyes with me wearing the disposables & said it looks
    fine from his end - but I wasn't very comfortable with them.

    My non-disposable's have a B.C. of 8.9
    The disposables had B.C.'s of 8.6 (or 8.6 & 8.7),
    I think. The doctor didn't have any disposables with a higher B.C.
    I checked websites etc & saw that no disposables aren't made with
    B.C. 8.9

    I feel this is the main reason for my discomfort.
    When doctors examine my eyes they always prescribe 8.6 or 8.7 but
    it never works for me - not even in non-disposables - I have tried
    non-disposables with B.C. 8.7 & they weren't comfortable either.

    So finally, the doctor represcribed my old non-disposables & I am
    again very comfortable.

    However, the doctor was very unfortable with me going back to
    non-disposables - he said that they aren't as healthy as disposables.
    He said that protein deposits build up & also they dehydrate & cause
    damage to the eyes for most people. However, he did examine my eyes
    & say that there is no damage at all to my eyes even after 10 years
    of wearing them & said that maybe next year when I come back, I could
    try 2week disposables to see if they work for me.

    Now, I am worried - are non-disposables really so bad.
    I wear contact lens for maybe a total of 15 hours in a week
    (not continuously). Sometimes it's more 25-30 hours, but mostly
    it never crosses 15 hours in any week.

    What is the best way of caring for the lens so that problems
    don't happen ?

    I usually, put it back in Kirkland Signature Multipurpose Solution
    when I am not wearing them - sometimes when I don't wear the lens
    for 2-3 days, they just lie there in the solution.

    Once in a month or once in 6 weeks,I use the enzyme tablets to
    deproteinize (once a month, not once a week, because, mine isn't heavy use and
    also because the Kirkland solution says "no separate protein removal

    Any suggestions etc ?

    If you want to broadly generalize, then I agree with your doc that
    disposable lenses are overall best for most people. However, if you like
    standard annual replacement lenses and you can keep them clean and not
    overwear them, they are probably fine for you. Do not worry. Enzyme them
    as you are doing (I would recommend weekly enzyming though).

    There are many, many brands of disposable lenses. I know of at least one
    brand that is available in an 8.9 base curve. Disposables were invented
    for a reason. Since the advent of disposable lenses, I have seen far fewer
    contact lens related problems, especially those related to dirty lenses
    with deposits. A soft lens is porous, much like a sponge. And, much like a
    sponge, it will attract and retain soil from the tear lipids and proteins.
    And, much as a sponge cannot be cleaned after awhile, a soft contact lens
    cannot be completely cleaned. Then there is the matter of torn lenses,
    unit replacement costs, convenience, etc., etc., etc. To top it off, any
    new lens technology is introduced in the disposable modality. Any of the
    new silicone-hydrogel lenses are disposables.

    Ask your practitioner about the Biomedics 55 2-week disposable lens in the
    8.9 base curve. The old Acuvue is available in an 8.8 base, and the One
    Day Acuvue in the 9.0 base. Also, don't sell the 8.6 Focus N&D short, as
    its smaller diameter makes it fit much flatter than most 8.6's.

    In general, disposables are healthier than non disposables as your doctor
    said. However, some individuals have very good quality tears and are
    successful with non disposables. If your vision is clear and your corneas
    and lids are healthy, then, for your individual case, there is not a problem
    in continuing with your original type of lens and care system.

    If I were your doctor, I would be nagging you considerably to change your
    habits, which I consider poor. These lenses aren't so costly that you need
    to preserve them for 8 years. Not only are these lenses made of a low Dk
    polymer, they are further compromised in terms of their O2 permeability by
    their thickness if they are torics. They should not be worn overnight.
    One of the potential side-effects of a lack of oxygen to the cornea is
    something called "pannus," or "neo-vascularization," which is the
    appearance of blood vessels growing into the clear cornea in a vain attempt
    to supply more oxygen from the blood. I would like to assume that this
    would be noted by your ophthalmologist during your ANNUAL examination, that
    is if you are going regularly.

    Incidentally, the Durasoft lens material was widely known "in the day" as
    being extremely "durable." It is, however, classified as an ionic
    material, and therefore tends to attract protein deposits more.
