Medical Forum / General / Vision / April 2005crystalens iol
01/11/05 my eye surgeon implanted in my left eye this highly touted new type of iol that is designed to flex using a hinge type action to enable corrected near, intermediate, and distance correction. this has not worked out as planned, even with a substitute lens of higher power implanted 02/11/05 With the second lens implanted nearly three weeks ago, i am severely farsighted with somewhat better acuity in the late afternoon. Anybody out there with a similar story? You, and apparently your doctors, are not being patient enough. I have had several meetings with the manufacturer of the Crystalens accommodating intraocular lens (IOL) and several more with some of the doctors who shepherded it through the FDA clinical trials. All concur that the Crystalens does not often accommodate immediately. In fact, the recommendation is to not even evaluate with any serious regard the accommodating power of the lens until at least six months postop. The initial diagnosis of an inaccurate lens power indicates (to me anyway) an implantation positioning concern more than actual IOL power concern. The exchange for an IOL of a different power, which overcorrects, may be a sign that my armchair analysis is accurate. I think what would be of great value, but is probably not readily available, would be an ultra high frequency scan of the anterior segment of eye to determine the exact positioning of the IOL. Also, I highly recommend you and your doctor have a nice talk with some of the surgeons who have implanted many of these lenses and the manufacturer.

For those considering a Crystalens IOL, you may find http://www.usaeyes.org/faq/subjects/crystalens.htm interesting. Glenn Hagele Executive Director Council for Refractive Surgery Quality Assurance Email to glenn dot hagele at usaeyes dot org http://www.USAEyes.org http://www.ComplicatedEyes.org I am not a doctor. I feel that I have been patient enough. I am approaching one year with the IOL's and if anything vision is getting worse. My implants resulted in farsightedness in one eye (20/100) and nearsigthedness in the other. I believe that more and more patients will be coming out exposing this product. By the way the manufacturer will not respond to any inquiries. I (and I'm sure others as well) would love to hear how the rest of your vision is with this lens.. I am going to have the Crystalens procedure done later this year and would be interested in hearing other people's experiences with them. Thanks. I'm surprised that you were able to get the lens replaced. I had questionable results from my cataract surgery, and 2 doctors have refused to replace the lens, saying the risks are too great. Maybe it was because I started out with high myopia, making risks for retinal detachment higher than the norm. Lenses can be replaced if the replacement is done soon after surgery. After time passes, they get more embedded in the eye and can't be removed nearly as easily. I had the first eye done in December and the other two weeks later. Three months and so far am very unhappy. My near vision is worse than before the implant. I am scheduled to have lasik in three days to correct the near vision. I hope it works.

I had lasik two weeks ago and only got 20/30 vision from that. So I'm very reluctant to have the other eye done. What doctors have done your procedures? I am in the Dallas, TX. area. I don't thing the doctor did anything wrong during the procedure. I am irratated that he told me after the implants that people in my age group would not recieve the full benifit. This only leads me to believe he was driven by profit. He has now done lasik to one eye creating monovision, This could have been done first at a fraction of the cost of the implants. Buyer beware! This is something that I see everywhere about this lens.. A misrepresentation of what it can do.. It is a great lens to be sure, but it cannot restore your near vision to that of a young person. The BEST that can be hoped for is 2.5D, which would give someone the near vision of a 50 y/o. 1.0-1.75D is a more typical result, which means that vision will be blurry for distances closer than 2-3 feet. How they are able to market this lens as a solution for presbyopia is beyond my understanding. I had similar results except it is nearsightedness. My Doctor had actually stopped this procedure as the results were not what he was expecting. My current situation is glasses and or contacts definitely not what I expected from all of the hype I had received. I am surprised that this lens is still marketed the way it is. It is not the answer especially for patients under 60 years. I am currently working with a class action suite against eyeonics. I do not think the lens is necessarly bad, I object to the marketing strategy. Also I truly believe that the $10,000.00 price is driving doctors in this field to put profit ahead of patient care. Just my openion of coarse. |
