Rezoom and ghosting problems?

by JustWant2See, Jan 14, 2007 12:00AM
Had a ReZoom lens implanted in one eye in May. About 8 weeks later had YAG treatment for early PCO. Since then I am happy with very good (J1) near vision, but unhappy with poor far vision (20/40). Also experience ghosting, not too bad indoors, but bad outdoors in higher contrast light or at distance.  



Dr. at first thought ghosting was due to slightly off-center IOL. On last visit, lens had mostly re-centered itself (undilated exam), and he thought ghosting was now due to a) residual astigmatism, b) still slightly off-center lens, or c) just the way multi-focal lenses work. He gave me a Rx for a lens for my glasses to correct vision/astigmatism (-.75+0.75x180). Lens barely had any effect on ghosting, but helped improve far vision to 20/30.



At night I have significant glare/halo problems, and halos are not centered on light source, but off to one side. I think if they were symmetrical around the light they would be much easier to tolerate. I think my vision would be much better if there were no ghosting. Reading signs is difficult because ghosted image from one letter overlies “real” image of adjacent letter.



Questions: What else can cause ghosting? Will it go away with time? Should ReZoom be able to give me ghost free vision? Would ReZoom in other eye help fix problem? Can lens be re-centered? Is poor far vision due to incorrect prescription? Suggestions?



I still need my other eye done. If ghosting turned out this bad in 2nd eye, I don’t know if I could drive at night.



Can anyone else comment on their problems with ghosting and ReZoom? Did they resolve with time?

ghosting is one of the well known and much reported risks/side effects of multifocal implants.  no, rezoom in other eye would likely not help IMO.  many, many people here with this same problem.  not really a great solution for your problem.

I also have only one Rezoom multifocal. I am not an expert, but have much experience with the halos, ghosting, etc. I know that the halos can decrease greatly, but can take a long time.  My started to decrease in the 8th month.

I do know that my halo were perfectly centered around any light source.  Sounds like yours lens is not centered.  I would not have the other eye done without getting a second opinion.

Also, it is odd that you have such good reading vision and poor distant vision.  Rezoom's best vision is suppose to be distant, and weakest, near vision.  Something is not right. I have ghosting inside only, which I believe is from astigmatisn.  Have an appointment with another doctor next week.  Again, I would get another opinion from a doctor who has done many multifocal implants.  Best wishes.

Welcome to the club! I also had bi-lateral Rezoom lenses implanted (2 months apart). I had halos and the need for glasses after the first Rezoom. I was told that everything would be fine after the second Rezoom. It made matters worse. Halos are terrible and I still need glasses. I was told to wait another two months for the adjustment to take place. I did so and I still had the same halos and the need for glasses. I was told to wait another 2 months. I guess the magic number is 6 months. Now at 6 months, nothing has changed - same old halos and same old glasses. Now I have to find some doctor that will take these lenses out.



My advise, if you don't see a change in the first couple of months, more than likely you won't. I have seen way too many postings in other sites to support my beliefs. Now you are beginning to see the Rezoom veterans (6 months and up) and no real changes, just the same problems and promises. Wait until you get the second Rezoom in. You'll be back in halo city.  Any doctors in Georgia that are capable of removing these lenses?



If there is a class action suit, please count me in. This product is overrated and now we are paying with miserable vision.

I'm glad that I found this site. Like many of you, I wished that I had checked on multifocal lens outcomes before having the surgery. I also had Rezoom lenses implanted 7 and 8 weeks ago - the right eye first and then the left. I can't say that I'm happy with the outcome. I see halos but not as bad as some people seem to report. My problem is ghosting. Other than in bright light(plenty of sun) conditions, ghosting is very noticeable indoors and outdoors. Before choosing the Rezoom lens, I was warned that there could be some halos and glare, but nothing about ghosting. No where in the literature is ghosting mentioned.



My doctor doesn't know what to do next since he feels that the lenses were implanted correctly - very little astigmatism, if any, and well centered. I have no dry eye and no PCO. The local Rezoom representative is also at a loss. He states that halos and glare is possible, but nothing about ghosting. The rep is also puzzled by the results.



What should I do next? Is this condition permanent? Has anyone resolved this problem? I did not expect my vision to be like this. The Rezoom lens rep made it sound like I was the only person with this problem. I was very surprised to see so many postings on this forum.  Any help/advice would be very much appreciated.

I sure wish I could help you.  But I also have ghosting.  But it is only inside in artificial lighting.  I know my halos are greatly decreasing after 8 months.  But my inside ghosting and inside focusing problems remain. I guess we are pretty much in the same situation.  It depends upon risking explants, or the wait and see aproach. So hope your ghosting clears up.  My halos, circles, finally, finally,  improved. Best wishes.

ghosting is a phenomenom, I believe, from not enough power difference in the add in the optic. When 3M owned the Restor lens, it had a 3.5D add, just as Rezoom does today. When Alcon acquired 3M Vision in the 90's, their R&D decided that more add (4.0D) would minimize these unwanted phenomena. The theory is that the brain needs more separation between the focused and defocused images with these bifocal implants. That is what is available today on Restor, and now AMO, the maker of Rezoom, has designed their next generation of multifocal with a 4.0D add. This is the Tecnis Multifocal that is expected in the US in 2008.

K-D - Thank you for your comments. Could you please give me a description of your ghosting image under artificial lights? In my case, I see the ghosted image of  the lights right below the original image. Brighter (indoor) lights make the ghosted image more noticeable and severe.



Hud - your explanation of how the optics work seem too complex for me to understand. I know from other postings in the forum that people with Restor lenses also have similar problems. Without debating which lens is better, is it possible to adapt to these unwanted images? Is the brain capable of ignoring this phenomenon? To your knowledge, has anyone (Rezoom or Restor patients) been able to see an improvement over time? Is ghosting a permanent problem?  Thanks.

i disagree with the following statement posted by hud:



"ghosting is a phenomenom, I believe, from not enough power difference in the add in the optic"



i just dont thinkt ats true.  thats like saying the majority of overweight Americans are that way b/c they eat too many twinkies.  when in reality there's like 1500 factors involved with each individual weight problem, not just "twinkies".



ghosting can be caused by at least 10 different factors that i can think of off the top of my head.

My ghosting is inside under artificial lighting. It is a thick white shadow that outlines an object, especially one that reflects. I do not have it outside, just inside. I have had it for almost a year. My halos started to decrease starting my 8th month, and are slight now, where they were disabling at first. So, maybe the ghosting will diminish also.  I just really do not know. Alot of wait and see with a multifocal. Best wishes.

I am confused. Has no one seen the same problem with Crystalens?



I have. It has been in since July 2005.

I am almost totally night blind in that eye and have been

since the time of the operation.



I had it implanted because of a cataract.

I told the doctor about it 4weeks after the surgery, and he

insisted that he had "never had this problem with crystalens before".

I was given pilocarpine to diminish the halos and minimize the

ghosts. In 30-45 days of constant usage of pilo, per his instructions, my retina

disconnected in April 2006. In July 2006, it disconnected two

more times(two weeks apart).



I am now 50% blind in that eye and am angry that I was never

told that pilo could "disconnect my retina".

This is the quote from the surgeon that has had to reattach

my retina three times, and says that I do not have a chance

for a fourth time.



I think a product action suit is now in order in my reading

of all the same problems that patients are having from these

lenses.



It is the same set of problems throughout these chat rooms, and

it seems to me that if all of the information was put together,

then the FDA might want to check up on what they have allowed

the American people to be subjected to without proper

warnings from the docs.



I still have to have a cataract removed and an implant in

the other eye, with the luck that I have been having so

far, I am not sure if I will be seeing with either eye in

6-8months!



Is there help out there?

I am`so sorry to read your post. All I can suggest is to get anoher opinion. Surely someone else can help you.

I am confused.

I am reading these rezoom lenses problems as if they

were the problems that I have had with the crystalens.

I know that this product has been defective since the

day that it was placed in my eye in July 2005.



The doc gave me drops a few months later to get rid of the

ghosts and the halos, because he had never seen any problem

like mine with crystalens.

The drops made my retina detach, per the second surgeon that

has put my retina back together for three times(once in April, and twice in July 2006).

My vision is only 50% and blurred in the daytime.

It is 10% to gone at night.



I am trying to initiate a med mal practice suit against the

doc that gave me the drops, because I was never told that

they can cause retinal detachment or I would have stayed status

quo.



I am also looking into a product liability suit against the

crystalens company and the drops mfg.



Not trying to hide the fact about these actions. especially

when I am now reading about the tremendous amount of people

that are affected by the same vision problems everywhere.



Hope all heals well for you.

At the very least, everyone with multifocal problems should report them to the FDA.  It is simple to do on line at FDA.gov.    Susan12345
