Proclear Compatibles

Discussion in 'Optometry Archives' started by Lothar of the Hill People, Oct 26, 2003.

  1. The jury is still out on how well my new Focus Night and Day lenses
    are working for me. They are generally very comfortable, but there
    are times when my vision is a bit hazy, and I think they may be
    getting lightly coated with oily lipids (although not as much as some
    other lenses I've tried). If I decide they don't work for me, I think
    I want to try Proclear Compatibles next.

    I have not been able to find much info on these lenses on the
    web--even the official website has very little info of substance, and
    I curiously can find no info on them on the U.S. FDA's website. I'm
    specifically looking for a copy of the package insert or anything with
    similar info. If my limited information is correct, these lenses are
    not approved for overnight wear. I wonder if anyone can tell me if
    there is something about these lenses that makes them inherently
    unsafe for overnight wear, or if anybody thinks that I will have any
    problems with them if I wear them on a mainly daily-wear schedule with
    occasion evenings of overnight wear. Has anybody worn them overnight
    or had patients who have worn them that way? Judging from their
    relatively high Dk/t value compared with other non-silicone lenses
    that are approved for extended wear, I would not think oxygen
    permeability would be the issue.

  2. First of all, Jan, I am *not* trying to fit contact lenses using my
    own judgement. One of the reasons why I am considering Proclear
    Compatibles is because they have come highly recommended by more than
    one competent specialist (including DrG in this newsgroup, whose
    opinion I respect greatly). I have gotten far more useful advice
    right here in this newsgroup, and from my own reviews of the medical
    literature, than I ever got from my old doc. I have no intention of
    simply deciding to try this lens and then order it from some
    mail-order store with no consultation from my doctor, and don't even
    know if it is even possible to do this. However, in my experience,
    doctors do not often know about the best lenses on the market for a
    particular patent's needs, and they may be more than willing to listen
    to suggestions by their educated patients. My last ophthalmologist,
    for example, had very little knowledge of silicone hydrogels and
    refused to prescribe them for me because he thought they could be
    harmful. Arguably the safest soft lenses on the market--harmful! He
    later admitted (quite seriously) that I probably knew more about
    contact lenses than he does (I certainly don't profess to agree with
    that statement, but I do know more about many matters relevant to my
    peculiar skin conditions than he does). My current doctor *highly*
    recommends silicone hydrogels, and fit me in them immediately when I
    went to see him, with no discussion of alternatives.

    That is the kind of advice I was looking for, and far more useful than
    your other statements. If the reason why Proclear Compatibles cannot
    be worn overnight is because they are too susceptible to damage (I
    would be interested in whether any of the docs in this group can
    confirm this), then I certainly would not wear them that way. It
    seems to me that any lens would be more susceptible to damage from the
    mechanical actions of being removed and cleaned daily, so I am
    skeptical of that statement. I know, however, based on my lifestyle
    that I will occasionally fall asleep while wearing my lenses, even if
    I have no intent to wear them extended-wear, so I am trying to get a
    sense for what options to discuss with my doctor. If I suggest
    Proclear Compatibles to him and he doesn't think I should wear them,
    then I won't. But what is the harm in telling him that I'd like to
    try them? Answer: None!
    I don't understand that sentence, and perhaps I am just reading it
    wrong. I have not come even close to trying all of the lenses on the
    market, and I see no harm (other than financially) in trying several
    different lenses until I find one that works best for me. No doctor
    can know based on an eye exam what lens will work best for the patient
    of all the alternatives on the market.
    I have never been advised against wearing my lenses overnight by
    either of my doctors, so I'm not sure what gives you the impression
    that I "keep trying" to do this. All of the lenses I have tried are
    FDA approved for extended wear. I am trying to determine what it is
    about Proclear Compatibles that potentially makes them any more
    harmful for this type of wear.
    I am not interested in being fit over the internet. I am interested
    in getting opinions from specialists and people who have experience
    with various lenses, so I can be more educated discussing alternatives
    with my doctor.

  3. Thanks, DrG, your response was helpful as always...

    That thought did occur to me, and I'm glad somebody else confirmed my
    thinking. If nobody can point out to me any characteristic of
    Proclear Compatibles that makes them inherently unsafe for overnight
    wear compared with other soft lenses in their class, then I will feel
    a lot better about trying them knowing that as much as I intend to
    wear them on a daily-wear schedule, I *will* fall asleep in them from
    time to time. I also know that there is an increased degree of risk
    in sleeping in any lens on the market, whether or not they are FDA
    approved for that purpose. It's very possible that given my peculiar
    skin conditions and tear chemistry, a highly biocompatible
    lipid-resistant lens that is not approved for overnight wear could
    actually be safer for me to sleep in than one that is approved for
    overnight wear!

    Thanks, I will definitely do that!

    You have gotten other advises too from this newsgroup for some excellent
    lenses but one by one they are excluded by you for several reasons.
    Why do you not visit a contactlensspecialist such as DrG face to face to get
    your problem solved instead of visiting an opthalmologist without some basic
    knowledge on contactlenses?
    You are trying the hard way in my opinion.

    I have gotten far more useful advice
    Find yourself a competent contactlensspecialist.

    However, in my experience,
    Strange situation to me, a doctor who prescribes what you want by lack of

    My last ophthalmologist,
    Not very professional I might say.
    Discutable, meaning "safest" when said in general.

    Strange doctors you have overthere knowing lesser on their field than the
    patient does.

    My current doctor *highly*
    Maybe my other statements are meant for other people too as a kind of
    My responds are not without a purpose and not only meant too be read by

    If the reason why Proclear Compatibles cannot
    No, this is not the matter.

    , then I certainly would not wear them that way. It
    Some lenses are weaker than others, nothing more nothing less.

    I know, however, based on my lifestyle
    Occasionaly falling asleep for several hours when wearing Proclear's is not
    a big problem most of the time.
    Keep in mind that this is said only when it happens by accident and rarely
    and not as a normal recommendable use.
    But wearing them night and day is another.
    In Europe we think about the night and day wearing a bit differend as
    specialist in the US do.(speaking general)
    One off the subjects involved are the metabolism debries that came out of
    the cornea from wich you can say that they stay for a long period of time
    between the lens and the cornea.

    If I suggest
    You are right here.
    Right again but keep in mind that EVERY contactlens comes with some
    discomfort, some with very very little, some of theme with more.
    If you tried them all, do you realy know wich one you have to choose
    Many postings (like this one) by you mentioned the overnight wearing so I
    thought it is one important issue to you.
    My excuses if I read and interpretated wrongly.

    All of the lenses I have tried are
    Approved but not nesceceraly to be used and or advised that way.

    I am trying to determine what it is
    Cooper Vision simple does not advise to use Proclear Compatable that way.
    Maybe the lens is most succesfull in wearing them in such a way.
    Maybe the reason why this succes could be change if they agreed in wearing
    night and day.
    A good company policy if I may say so.
    A good eyecare professional should know and must be capable off telling you
    the same stuff as you got here.
    Also he or she has the best chance of giving you a good advise by "seeing "
    your problem.

    Proclear Compatibles do tear relatively easily, for reasons unknown. I
    think that this is the propensity to "damage" that Jan was alluding to.
    Obviously, a torn lens will fail very quickly, and cannot be worn at all.
    However, this does not seem to discourage most of my dry eye patients from
    buying more of them.

  7. Jan, I just discovered this reply from you. I would have replied
    earlier, but didn't see it, and I don't want you to think I was
    ignoring you...

    I did go see a specialist, after I left my last ophthalmologist, who I
    was convinced knew less than I did about contact lens problems. The
    new doc is very well published in contact lens issues, as is his
    fitting technician, and I get the impression that he is well known.
    He was one of the first doctors in the country to be chosen to
    evaluate Proclear Compatibles. Even so, I'm still experiencing
    problems which I'm trying to figure out, and I don't want to rely on
    the advice of any one person, which is why I like the expertise in
    this newsgroup so much.
    In my experience, many doctors prescribe what their patients want, to
    a certain degree, even if it is not *necessarily* what they think is
    best for them. This is apparent, for example, with the increasingly
    widespread prescription of antibiotics for infections that are
    probably not bacterial. I actually had a doctor tell me one time that
    an illness I had was viral. In the next sentence he said he'd be
    happy to prescribe me some antibiotics if I wanted them! I presume he
    did that mainly to give me a feeling that he was actively doing
    something to try to treat me, rather than just telling me to go home
    and get some rest. I think it is a very good idea for patients to
    educate themselves about their conditions and suggest to their doctors
    what course of treatments they are interested in, as well as which
    ones they are not. I'm certainly not saying that patients should
    self-prescribe their treatments and only go to doctors who will agree
    with them, but I also don't think patients should always blindly
    accept whatever treatment a doctor suggests for them without
    discussion. My last doctor admitted to me on a couple of occasions
    that I taught him something, and I respected him greatly for saying

    I don't believe that a doctor needs to know everything about every
    potential problem in their field to be a good doctor. That's what
    consultations with specialists and literature research is for.
    That is an interesting observation that I had never really thought
    much about, and could explain why my vision has been blurry after
    wearing certain lenses overnight.

    I'd like to think I am doing my experimentation in a systematic enough
    way that I would be able to decide later which lens worked best for
    me. I keep a daily journal of my own (admittedly subjective) "comfort
    rating" and "acuity rating" on a scale of 1 to 10, along with a
    sentence or two of notes for that day. I can then go back months
    later and see how well a previous lens compared with a current lens
    and decide which one worked better for me.
    That's a good thought in theory, but I don't think I agree that this
    is the case in reality. Every doctor has his own area of specialty,
    and can't possibly be an expert in all subspecialties. My old doctor
    may not have been an expert in contact lenses, but I am confident that
    he was a good medical doctor with the ability to medically treat any
    complications that might have arisen. Likewise, there are
    optometrists who may be renowned experts on contact lenses, who I
    would not want to seek out for treatment or advice for certain eye
    conditions. The fact that I know more than some eye doctors about
    certain contact lens issues does not make them bad doctors--it simply
    means that I have done more focused research on current issues than
    they may have received in school, or have communicated with
    specialists who know more than he does in on a particular issue.
