restor

About two years ago I had Restor lenses  done to both eyes , To this day I have no  intermediate vision and lots of halos.
Lasik MD in Toronto that did the procedure got me to have Yagg done to both eyes to no avail
My question is can I have the Restor lenses removed and Tetraflex put in I have heard a lot of good things about them.
Also the new Restor 3.0 Alcon claims to have fixed the Intermediate vision problems and better sight in dim lighting.
Right now I am in Limbo .
Please help.
THANK YOU .
Sincerely.

Lasik MD certainly has good marketing.  I live in Toronto too.  If by two years the ReSTOR lenses aren't doing what you want, and you are still unsatisfied with them, you could realistically consider explantation.  To clarify I had multifocal lenses implanted two years ago (Tecnis not ReSTOR) and have encountered many of the aberrations you report.  The nature of both lenses is (hopefully) good distant vision and very good near vision.  Mid-vision is poor with both.  I believe the Tecnis mid-vision starts and end before ReSTOR.  Other than the halo issue, some people -- especially with large pupils -- do not adapt well to the ReSTORs.

There hasn't been much feedback on MedHelp regarding the Tetraflex IOL.

Most posters on MedHelp are in the American market and Tetraflen is not currently not available there.  It has been available in the UK and Europe for some time.  The few posters who wrote about it did not have much negative to say.

The ReSTOR 3.0 sounds intriguing, but I've only heard some mention on MedHelp.  From this article:

http://www.medicalnewstoday.com/articles/121632.php

it looks like it has a lesser add (+3.0 instead of +4.0), giving somewhat better mid-vision due to the lesser separation between the near and distant images.  Still that doesn't appear to give "true" mid-vision.  Add or difference between near and distant focus was moved from +3.5 to +4.0 on earlier versions of ReSTOR to aid wearers in differentiating between near and far.  Apparently they have a working +3.0 model.

Back to the Tetraflex, my biggest question is whether and after two years of not using your eye's ciliary muscles to focus your natural lens ... can it be used to focus the accommodative Tetraflex lens?

In my case I've become accustomed to not using my mid-vision as much and, in fact, over time have been able to work with my mid-vision without my +1.00 readers.  I don't have issues with dim lighting or night driving.

If you really aren't happy with your current vision please take your time and use the search engine at the top-right of the page to find what there is on Tetraflex and explantation.  Another poster, light show, gave positive feedback regarding Dr. Rootman at Toronto Western Hospital.  Read this thread:

You'll still need to go through the referral route.

There's lots for you to think about.  Do you want another multifocal in your eyes, even if some of the same aberrations were to return?  You might not be suitable for an accommodative lens such as the Tetraflex if you have been using a multifocal IOL for the past two years.  (This one I very curious about too.)

Good luck with your decision!

Neither the Tetraflex nor the ReStor 3 are available in the USA.  From what little I've read, the accommodating ability of the Tetraflex hasn't lived up to expectations (i.e., you'll still need reading glasses.)  The ReStor 3 is very similar to the Tecnis multifocal.  It reportedly allows the recipient to read at a more comfortable distance than past ReStor models, and it might improve intermediate vision slightly.  But it's still a bifocal lens without a zone for intermediate vision.

Unfortunately, explanting IOLs carries significant risk, especially post YAG.  Bighi, I'm not sure that the potential benefits of either of the IOLs would outweigh the risks for you.
