lens implants

[douglasi]

do you know of long term success cases with lens implants for long sight please?

there seem to be warnings of possible complications and risks with ICL on most sites.

Dr.
Would you know anything about decompression surgery for TED?

The central portion of the ReZoom is 2.1mm for distance. The second zone which is near. With a 2mm pupil you will have distance and intermediate.  Once you get into the 2.2 to 3mm range you pick up near. The outer ring does not account for much at all. It has to do with light distribution. He might have been checking you and watching your pupil respond without you even knowing it. The contacts being off is for your cornea to retain its normal shape for accurate k or keratometry readings. You use the K readings and the axial length measurements or distance from the cornea to the retina to input into a formula to come up with the power that you need. Some do this with immersion biometry which is more accurate than hand held and some also use the IOL master.

Thanks.  Do you think I should be concerned, that if in a pre-op visit the MD/office did not check my pupil size in a dark room and they did not ask me to keep my contacts off for 5 days  before "measurements" were done?  This is the MD that wants to put in the REZOOM lens.  I kind of insisted on these things being done because I   understood these were important details when #1 deciding on the REZOOM lens and #2 for accurate measurements.  Is the contact thing for the accuracy of the topography of the cornea or the axial length.. or neither?  Perhaps these things are not important. When I asked if my measurements were different this time (no contacts X 6 D) vs. the first time they were taken (10 hours out of contacts)I was told it could effect the corneal measurements -but didn't really get a straight answer.  Also, if the pupil gets smaller when focusing NEAR, how does the light hit the outer zone (near vision) of the REZOOM? Perhaps you can see better w/ the REZOOM in darker lighting conditions due to this.  Thanks

I read   of a case in Spain, I believe, where a phakic IOL produced zonular dehissence. This article was written Jan 2005 I believe. I don't know if that is significant or not.  Are the multifocal lenses, Rezoom and Restore, considered phakic IOL's?

The ReZoom and Restor are not phakic IOL's. Phakic IOLs are implanted in the eye while it still has the crystalline lens. It is not removed. They are for high myopes that do not have cataracts yet desire great vision without contacts or glasses and due to the fact they are not lasik candidiates.

As for as track record for phakic IOLs (Artisan lens), also known as Verisyse (pronounced Vera Cise like precise) here in the US -- they have been around since the mid 1980s. 1986 to be exact in Europe. They are made of PMMA (poly methylmethacrylate- highly refined hard plastic) which was first implanted in 1949. FDA approved here in the US in September 2004. They are permanent yet reversible if needed. Many young, active people have them in their eyes. They are good for people that are either too near-sighted for LASIK, or unable to have LASIK because of too dry eye, too thin cornea, or possibly even too steep of cornea. The vision is incredible. Many surgeons prefer them over LASIK because of the quality of vision post op. The ICL, or Visian in the US, just recently FDA approved is a "sulcus" lens. This means it goes in through a smaller incision, (for now -foldable Verisyse in coming in few years). The down side of ICL is that more likely to cause cataract because it sits right on top of the natural crystalline lens.

i dont know if anyone knows of long term anything with "implantable contact lenses" or phakic iols.  they're too new.  however they are fairly similar to anterior chamber iol's which have been around forever and are fairly safe.
