the fact that most surgeons prefer& use one lens or the other does make it more difficult.
do not be scared of an accommodating iol, even if you do only have 1 eye.
I personally like the restor a

"The most remarkable statistic from that study is that 80% of the patients in whom the (ReSTOR) IOL was implanted bilaterally reported not needing spectacles for any activities after the surgery—not for distance, near, or intermediate vision tasks," Dr. Mackool said.
He observed that result compares very favorably against outcomes associated with the Crystalens accommodating IOL (eyeonics) and the Array multifocal IOL (AMO), for which reported rates of

"The ReSTOR IOL is truly a revolutionary implant," Dr. Mackool said.
Four hundred sixty-five patients received bilateral ReSTOR implantation during the FDA trial. Of these, Dr. Mackool implanted 43 lenses. The average patient age was about 65 years.
In that study, the vast majority of patients (84%) who underwent bilateral implantation with the ReSTOR IOL had a distance

I am in a somewhat similar situation to the initial poster but with slight differences. I am 50 and only the right eye needs surgery at this time and although I still have relatively good vision in the left eye but it will need surgery at some point. My optomistrist has said the same thing: "I would not put the multifoacl IOL in at this time". I must add that I am photographer so I am used to good, sharp vision (and that is what I want to have after surgery). Although it would be nice not to have to wear glasses that is not the most important issue. I want the best possible vision after surgery that I can possibly have and if the IOL/glasses combination will give that to me then that is fine. I have my opthalmology appointment tomorrow so I will get his side of the story then.
Thanks to all who may have any additional insight.
I am wondering what is the expected corrected distance acuity of the conventional monovision IOL? Obviously, no one wants a little "blurry" vision at any distance. If I have to use glasses to work, so be it. I am afraid though that fixed focus lens with distance correction means needing one pair of glasses to work on computer at 2-3 ft. Then another pair to walk around to see people at 4-10 ft. Another pair to drive and see street signs at 15 ft with the car instruments bifocal reading. Maybe no glasses to see well beyond 20 ft, but when this circumstance really happens? Possibly, when I am on vacation, sightseeing? Not in every day life. My fear is that I will end up with similar amount of pairs of glasses I have now if I choose monovision lens. If I have to have the surgery anyway, I might as well improve the quality of my life as well as my vision all in one shot if that is possible with minimal exceptions. I am assuming that Restor can be corrected with glasses if necessary to perform certain activities like computer work.
if you go with a "traditional" single focus iol, you will likely need multiple pairs of glasses, or at least glasses with multiple rx's in them (bifocals, trifocals or "progressives"). if you go with the restor, you will likely need fewer pairs of glasses, but you will also likely be slightly BLURRIER all the time and at ALL distances, both with Rx glasses on AND without glasses on.
"monovision" means correcting one eye for one distance, and the other eye for a different distance...usually the dominant eye for farter than 20 ft and the non-dominant eye for 16-18". when you use the word "monovision" while talking about cataract surgery, you are implying using one single-focus IOL for one eye to see at great distances, and using a different power single-focus IOL for the other eye to see well up close.
Thanks again.
I also read that in all multifocal or accommmodative lenses the optimal vision results are achieved when implants are bilateral. Not having this luxury with my bad eye, I am opting for the best clear vision I can get with the traditional method and glasses to correct all other distances. I also have endured enough "blurr" in the last few years with my cataracts and cannot bear the thought of dealing with it for the rest of my life (if I want to avoid risky replacement surgeries down the road) because I chose the wrong lens. I guess my cataract did not come in an opportune time when technology could provide "having it all".

The ReZoom gives you a full range of vision from near to far and 20/20 distance. The only accoomdating lens in the Crystalens since it is supposed to move back and forth. The others are bifocal or multifocal. The ReZoom is a true multifocal. The Tecnis is a monofocal but is different. It has two FDA claims of improved night time driving and improved functional vision so it is better than the average monofocal lens. There are quite a few one eye patients that are doing will with the Array lens which was the predecessor to the ReZoom. But if you are leary look at the Tecnis.
It is a more forgiving lens than the others.
I am seeking a second opinion on 1/3/05 to determine what to do:
1)Have a lens exchange to better fit the left eye with the proper power.
2)Live with left Restor lens and have lasik to correct the remaining astigmatism and hypeopia caused by the wrong power on the Restore lens.
I am particularly interested in hearing IF the knowledge of the wrong power of the Restor lens I now have will help in getting a very good power prescription for a second lens exchange. Having two botched lens power selections is NOT something I want to endure.
Also,I am concerned how long I have to get the lens exchange before the Restor lens "settles in."
I want to get the left eye issues resolved before I tackle the right eye.
I will see 2 new doctors on 1/3/06 along with the doctor that did the surgery on the left eye and I will update you following.
My current concern is that the outcome statistics offered by Victoria Eye Center for ReSTOR lenses is 80% of those with the lenses don't need glasses and 90% would do it again. Yet, few if any have posted in these related sites anything positive in their personal experiences with the ReSTOR lens. I would welcome some positive comments from people who have had these lenses installed.
More follow-up postings describing my results over time to follow.
Dr. #1 is a respected Ophthalmologist at Southwestern Medical Center. He says the cataract removal has left me with high order abberations and significant astigmatism. Oddly the astigmatism wasn't remarkable before the surgery.He says a lens exchange would not solve my astigmatism problem and suggests lasik or surface PRK to correct both astigmatism and hyperopia. He says he would attempt to lift my 8 year old lasik flap(yikes!)and failing that,do surface PRK. Apparently cutting a second flap is not a good thing to do.
Dr. #2 is a young Ophthamologist in Fort Worth.He said he had never seen post surgery astigmatism like I have.He says a lens lens exchange is a better route(than lasik)but says he would bail on Restor and use a monofocal lens. He says getting the power closer to -+0 ,rather than farsighted,is not an unreasonable/unattainable goal. Both #1 and #2 said contact lens could be considered as a "status quo approach."
I also saw Doctor #3 who did my cataract/Restor surgery on 12/12/05. Doctor #3 is a young doctor who does lots of Restor work. He sides with Dr. #1 but said he did not do lasik himself anymore.He thought the contact lens idea was worth trying.
Assuming I went with a lens exchange he did NOT like the idea of a monofocal rather than a second Restor. He seemed interested in dismissing me -- and said he would see me in 3 months.
Here is my take today:
1)The status quo seems like a dead end because I don't like the idea of a far-sighted astigmatic left eye while the right eye remains nearsighted. Wearing glasses with a 3.75 diopter differnce is not really doable. Realistically I expect to need glasses for golf and reading no matter what route I take.Contacts might allow the "staus quo approach" to work but I see this as a longshot.
2)I don't like the idea of raising the 8 year old lasik flap.It is interesting that the doctor with the most experience and a prestigous background came up with this aggressive approach.
I would want to know a lot more about raising a flap and current surface/PRK techniques before going that route.
3)The right eye can't be overlooked. If I stay with status quo (farsighted Restor)in left eye then am I bound to target a similar outcome for the right eye so they will "match?" (lessen the diopter difference). Again,I am thinking about the ease of wearing glasses ultimately.
4)I will try contacts right away.I have an excellent Theraputic Optometrist who will give me my best shot at contacts.
5)I will get at least one more opinion and try to get further clarification from Drs. #1 and #2 after better outlining my concerns to them.
I WOULD BE MOST INTERESTED IN YOUR THOUGHTS. I am now 23 days out from my cataract removal.If you have a suggestion for a doctor in Dallas/Arlington/FW for my 4th Opinion I would be appreciative.
Go to Wes Herman in Dallas. He does lasik, has Array's in his own eyes and will do the right the thing if he can help you. 214-361-1443. See him and no one else. He has the experience. He has done both ReStor and ReZoom. The Array is the predecessor to the ReZoom. Let me know what happens.
Have talked to three surgeons so far, one of whom implants restor, rezoom, tecnis monofocal, and crystalens. He also is in FDA trials for tecnis multifocal. I don't know how far out FDA approval of that IOL is. His study group is full; I am not eligible to get the tecnis multifocal. His recommendation is for me to wait a bit until I am not correctable to 20/20 DVA, and, assuming this is within the year or so, then to implant the crystalens, and do lasik (?) to correct any bothersome astigmatism. He says that he sees me as a "refractive patient". Could someone explain that term please? I had tried monovision correction with contacts some years ago, and I was never really happy with that.
It sounds to me from reading these posts that restor is problematic with the night driving halos, etc, and the lack of crisp acuity throughout the whole range. I've also heard (from doc #2) that the crystalens hinging mechanism fails in as little as three years, rendering it essentially a monofocal IOL. Further, it sounds like the reading capability of the crystalens would not be enough reading for me. This leads me to prefer the tecnis monofocal IOL, and just put up with glasses (or contacts, maybe?) for near and intermediate. However, if I could do this without glasses, that would be my preference. Still young and active (ski, golf, drive my 14 year old kid around, etc.). Can anyone speak to how the crystalens compares to the tecnis IOL in terms of "functional vision" and contrast sensitivity? Those seem to be the biggies for folks complaining of night driving difficulties. Does anyone know how soon the tecnis multifocal will be available, and if it is any better than the restor with respect to halos? Is the improved functional vision that is touted with the tecnis monofocal also a selling point for the tecnis multifocal? If I opt for tecnis monofocal, can I wear some kind of contact lens which would be "blank" for distance, and only correct for intermediate and near?
Also confused by conflicting (?) reports on the UV blocking capability of the crystalens. These two sites both indicate that the crystalens does not have UV blocking capability: http://www.agingeye.net/otheragingeye/crystalens.pdf http://www.crystalens.com/crystalens-physician-labeling.pdf
This site seems to indicate that it does have (some? but not sufficient?) UV blocking capability:

I'm trying to do my homework now, so that when the time comes, I'm ready to pull the trigger. Would appreciate any help, personal experiences, etc. Thanks.
As far as determing the power of the lens to implant there are a couple of methods. The IOL master is one and an A-scan is the other. Immersion A-scan is more accurate than hand held. The doc will use a machine to measure the steepness of your cornea to get K readings which the horizontal and vertical axis of your cornea and for astigmatism. He will then use an A-scan or IOL master to measure the length of your eye. He will take this information and input it into a third generation mathematical formula to come up with the right power for the desired refraction. Depending on the amoung of astigmatism you have, they can operate of the steep axis to reduce it or perfrom limbal relaxing incisions at the time of surgery or later in the office. Lasik can be also used to correct more astigmatism. You will probably have to be out of your contacts and just wear your glasses for a period of time to let your cornea resume its natural shape. Most surgeons will personalize their surgeon factor over a series on the monofocal counterpart of the multifocal lens platform and the companies require them to do this to be certified. By doing a series of 25 or more lenses, they will come up with their own a-constant to be more accurate which they input into the formula. This has just gotten better and more accurate over time with immersion biometry and the IOL Master. Some will use both in your workup. As far as the silicone versus acrylic with the Tecnis, it becomes surgeon preferece and with any designs and materials there are pro's and cons that can be debated all day long but there have been millions of both implanted and silicone has actually been implanted longer than acrylic. My mother and stepmother have silicone monofocal lenses and my dad has silicone Array lenses. The ReZoom is an improved acrylic version of the Array lenses which has had over 7 years experience implanted in the US. It replaced the Array. I hope this helps as there are many opinions and you are in a great area with some very well known surgeons who are nationally and internationally respected. But they all have their favorites just as you probably do in things you work with and like. The most important thing is to look at your life style and what you do from your work to hobbies and the state of your eyes and then try to match the best thing for you. Some surgeons even have used a blended vision of different IOL's to give you near with one and better distance and intermediate with the other. You can imagine all of the possibilites as your research this more. As far as night driving, if you have posterior subcapsular cataracts that is when it will bother you the most as light hits and scatters from headlights. Hope some of this helps.
My current optical prescription for the left eye that will undergo an exchange is :sphere +3.50 cyl -2.50 axis 177.
The original Restor lens used that got me to this farsighted condition was 17.5 D. What "ballpark" Restor power would you use to get me back to "0" or slightly nearsighted? I am only looking for your best guess here.
I will get one extra and possibly two independant power selections next week.
I would appreciate any other thoughts you have on my selected course of action.
At this point, I'm planning to wait, maybe till next fall (when the nights get longer and night driving becomes more of an issue because, well, there's more night!), and go with the tecnis monofocal. I'm thinking about an a la carte approach now, rather than one IOL and one surgery which will do it all. Accounts of restor implants make me kind of leary.
Anyway, after the tecnis monofocal surgery recovery period, I believe that I could consider contact lenses again (I've worn them now for years and years; they are my primary means of correction now anyway), with "blank" for distance, presuming they've gotten the IOL power correct, and only correct for intermediate and near with the contacts. I'd really like to hear from anyone who has tried this approach.
If the distance does not get corrected to 20/20 with the tecnis monofocal, I also believe that lasik would be an option (also had one doc say that he could do the limbal relaxing incisions at time of IOL insertion for the astigmatism) to correct distance VA only. Then, perhaps years down the road when there are solid surgical tecniques for presbyopia correction with IOLs, I could pursue that.
My biggest problem now with my posterior sub-capsular cataracts is the loss of acuity for night driving (I'm still legal, though). The tecnis monofocal addresses this issue particularly. If people's experiences with that IOL are living up to the claims, then it would certainly seem to be a prudent, conservative, and appropriate choice. If I could hear of some living proof of contact lenses following tecnis monofocal insertion, I'd really find that helpful. At 51, and with my long history of contact lens wear, I guess I could be comfortable doing it for another 10 or 20 years. And in that time, who knows what surgical procedures for near and intermediate correction may be present? This demographic will certainly be driving innovation in this field in the years to come.
I do have another concern about just how they go about measuring for IOL power. One doc has told me that his practice uses the IOL Master. I've read some stuff about that, and wonder if it is perhaps not the best with posterior sub-capsular cataracts in particular? Is immersion A-scan more accurate with this type of cataract? Is it more invasive? IOL Master looks pretty simple and non-threatening.
All this having been said, I do still sort of wonder about the coming (hopefully) tecnis multifocal. Does anyone have info about what this IOL will be able to claim? Same superior contrast sensitivity as the tecnis monofocal? Reduced incidence of halos and other night time disturbances, compared to present multifocal technology?
Thank you all, and good luck to everyone grappling with this issue.
I really am interested in experiences of folks who've worn contact lenses (multifocal, with "blank" for distance) following monofocal IOL implants. Maybe this a la carte approach will be the best way to get the best of everything, albeit, having to wait who knows how long for solid surgical enhancements for the presbyopic part. On the other hand, I don't want to pin my hopes on that route (contacts) if there are compromises I would find unacceptable.
Thanks again, and good luck to all.
