Collamer intraocular lens
Posted , 13 users are following.
Hello! Unfortunately after 6 months of really disturbing glare, halos, flickering and so on with an Acrysof, an acrylic hydro-phobic intraocular lens implanted in my right eye, I asked to have a lens exchange. I made some research and found several studies suggesting a lens called NANOFLEX made of collamer, a special polymer which has a very high water content, a very low or nonexistent degree of glare and halos, it is totally bio-compatible, it doesn't attract proteins, zero glistering, zero reflects, it has a dense core which mimics the human crystalline ... it even has some accommodating function so people with that lens can see relatively well both close and far. I asked my surgeon and he criticized that lens telling that "it's an old model" ... what?! Who cares? The lens he put me and he had magnificent it, it's brand new and yet it's causing a lot of problems to many people (even on this forum there are several complying bitterly about that). So he has a sort of prejudice against the nanoflex and said he won't use it on me. Now I'm really wondering why is that ... What could be wrong with that lens? Did I miss something?

Seems many of us on Patient have flicker, glare, stars, and halos. Mine is mainly night with single point lights....yikes. Looks like a bomb going off. Also flicker from florescents glare. I have Silicon Technis Z9002 lenses. They were put in 4 months ago. They were over corrected by about +.75. I also have PCO and had Macular Edema. So I don't talk to old surgeon. I have glasses to correct near and distance. Soooo
I have been under close watch of new Ophthalmologist and the fix is, cure Edema, then do YAG for PCO, then touch up Distance with EPI PRK..surface correction. I have asked 10 times if it would be better to replace lenses and not blow a hold in capsule. He says I'll need Yag either way. However Once the YAG is done no really good way to replace lens. He strongly recommends not changing lenses do to risk.
So did you check PCO? Maybe YAG laser will help. Plus any comments about my plan would be great. AT201?

Very sorry to learn about all the issues, which you have right now.
I think that your opthamologist's plan is basically good, although it can be tweaked a little. My thoughts are are as follows;
1. I think that getting rid of the Edema should definitely be the first step. Did the ophthalmologist give you the reason for it? Has he given you some eye drops to help the recovery from it.
2. I also will not encourage changing of the IOL at this stage. That may or may not fix your vision issues and create some new ones. However, that does not necessarily mean that you should have a YAG laser to get rid of the PCO right away.
You have to first have a reasonable idea of the improvement you may or may not see after the YAG laser treatment.
Thus, once the edema is minimal, you need to know what your exact eye prescription (spherical and cylinderical) is and what your best corrected vision (with glasses) is. If your best corrected vision is very good with glasses, then getting rid of the PCO may not be necessary right now (even if you may need it in the future in case of worsening of the symptoms). YAG laser to get rid of the PCO is straightforward and usually trouble-free, but any surgery has a chance (even if small) of having an unintended consequence,
Just as a minor side comment, I have had a PCO in my left eye (used primarily for reading) for the last 18 years, but it is not a big issue for me, and my Ophthalmologist has never tried to convince me that it is worth getting rid of just to achieve a minor potential vision improvement.
3. Once your corrected vision with glasses is good (without or after YAG Laser treatment), then it will be a good time to consider PRK or Laser Enhancement for the vision correction, if you don't want to wear glasses. You may even want to play around with slight changes in prescription of the 2 eyes to see if mini-monovision will work for you, to achieve the best focus distance for each eye so that you don't have to wear glasses for most activities.

Thanks AT. I think M Edema is going away ok. Vision has stabilized last 3-4 weeks. I sure wish original surgeon explained lens choices better. Person that posted this lens...."Oculentis Mplus X" multifocal IOL seems like a winner!!
Edema was from surgery, 1-2% get it even with proper surgery. So far it was found only in right eye. Caught it very early on, about 5-6 weeks after surgery. Yes NSAID drops were done for 8 weeks and steroid drop for 4 weeks. Both were only 1 per day. Now off drops and hoping edema does not return. Dr. says it comes back often, so hopefully no for me. I'll know Dec 8.
Good point on PCO. Ill try to determine vision gain with YAG or no YAG. However to get proper Rx with EPI PRK dr wants to do YAG first as lens can move a bit and change Rx for surgery.
Seems like I hear high risk and almost no risk on remove and replace lens. Very mixed opinions on this. What do you all think?
So yeah not great options but we'll figure it out. Thanks for your help.

PS...Correction with current progressive (post surgery) is +.75R, +.5L with +2.50 add. Small .25 astigmatism at 35 degrees. That give me pretty sharp vision.
Last, what would you guess YAG would do to help glare, halos, stars, and some wax paper vision?
You've been thinking about that for 18 years, so maybe you have more input on that.

Cataract surgeons get paid a set fee by insurance to put in a standard monofocal lens. If they are in network with your insurance, this is all they can get. Certain lenses, (lenses that correct astigmatism, multifocal lenses etc) as are certain services (eg laser) are approved by medicare, and as a result by private insurance, as "premium" where added fees are permitted. The Staar nanoflex has some premium features, but Staar never got it approved to bill extra for premium. So it is a great lens but the surgeons make less if they use it. The money in his pocket convinced your doctor what you needed.
