Smile Hello, new member with ? about Multifocal lens from Cooper Vision.

Hello!

I am new to soft contacts, previously wearing RGP. I need multifocal lens and my doctor had me try Cooper Vision Frequency 55 Mutlitfocal. What about Proclear Multtfocal as an alternative? I am interested in sharp distance vision, as well as seeing the computer screen and reading comfortably. He fit me with single vision lens first - not wanting to do multifocus because of my slight astigmatism. However he found that I can have good / excellent distance vision without toric lens. Reluctantly he let me try Frequency 55 Mutlitfocal. I need him to make the distance lens stronger. He is fearing that if I get good distance then the reading will not be strong enough. I am near sighted.

What do you think about this. Can I get great distance and reading. ?
My prescription for single vision is o.d. -4.25 and o.s is -3.25.

Thanks for reading this.

Hi Calvin. Welcome to Lens 101.

Your question is a little tough for me. I'm not an eye doctor and have never fitted lenses, but I think contacts are an individual thing. Without knowing anything about your eyes other than the prescription that someone else measured, it would be hard to say "Try X brand contact lenses."
Don't worry, though. There are others in this forum that are a lot smarter than I am. They should be along soon.

Thank You Horseluvr.

I was just wondering if there are many people out there with multifocal lens but don't have near perfect correction because the dispenser had to weaken the distance to improve the reading or visa versa.

Hi Calvin. I don't wear multifocals either, but I wouldn't be surprised of there were some eye doctors out there who might make some concessions in one area in order to improve another. Sometimes your options are limited and you have to decide if you'd rather be able to read fine print or read signs on the highway. Let's hope you can find a way to get the best of both worlds.

I'm in Proclear Multifocals: non-toric in the left, mild toric in the right. Is my vision as crisp as in RGPs? No, not really, but I CAN wear the Proclears all day in relative comfort, and I couldn't deal with RGPs at all. In my case, I did have to make some concessions. My first year, I opted for distance over near and wore readers. This year, I've opted the other way: I no longer need readers at all (I'm LOVING this) but my distance is so-so. It's fine for driving, but do have trouble reading small road signs. Thank heavens for GPS turn-by-turn! I think each case is so individual that there is really no substitute for just trial-trial-trial for as long as your ECP is willing to work with you. For me, the whole adventure is worth it to be out of my glasses.

Good luck to you!

See Calvin? Horseluver was right. It didn't take long for someone with experience to chime in.

Thanks for your contribution to this thread, HMBgal. I think you're right about just trying the different lenses offered by your eye care professional and see what works for you. It's like they say in those commercials. "Ask your doctor if Proclear Multifocals are right for you.

Cool Great revelation about optimizing for distance - OR - near vision.

HMBgal - your experience with having the prescription optimized for distance and then trying the opposite to optimize for reading was great. This site has been great for getting feedback and information.
Thanks HMBgal, horseluvr, garfield21 and Klingons4peace.
I would like to share that I probably should have stayed with RPG's as I've worn hard lens for over 30 years w/o problems. And the sentiment seems to be that RPGs give just a bit more visual acuity. My current OD steered me to softies, which I found are better than in early days as the softies back then definitely did not give as good vision as the GPs. I have dry eye problems more frequently during the day with the softies - another reason GPs work better for me. And I understand HMBGal's dislike of GPs - they definitely require more effort before you get used to it and a relative insensitivity to foreign objects in the eye goes a long way to accepting GPs.
With all that said, I'll see my OD today (probably last time until next year) and see if he'll agree to make the prescription for my dominate eye, a bit stronger for distance. We already went the route of left eye fair distance but good reading and right eye slightly better distance but lousy reading - and I'm ok with this sort of Monovision. If he can just tweak it more to give me Good (as opposed to middling) distance in the right eye - I'll be very satisfied. Of course, from comments above and other postings - having perfect distance and close vision is a MYTH propagated by the lens manufacturer! I so hoped that the technology had progressed far enough to give me perfect near and distance vision, which I was hoping for when the OD suggested trying soft lens.

Thanks for sharing, Calvin. I'm glad you like Lens 101 and find it helpful. That's probably the nicest thing you can say about this site.
So you're saying that a person can never hope to see both close up and far away with Proclear Multifocal contact lenses? I think it would be hard to speak for everyone on this. Anybody out there disagree that this is a myth?
Please let us know how your appointment goes. Here's to your good eye health.

Default correction for presybyopia and near/far sightedness not in reach for many.

Lucyfur -I' meant that in general, not just for the Proclear Multifocus brand, getting perfect reading and distance is not possible for many users. There often is some compromise - optimizing for one condition over the other. The lens cannot be made to satisfy both - for many people. There probably are users out there that have gotten perfection with softies. However many find that bifocal or progressive eyeglasses give them perfect vision but not with contacts. Furthermore, my old RGPs were also a compromise - the practicioner said that if he increased the power for reading, I will lose some acuity for distance, and visa versa.
So I hope new users are not disillusioned - they may or may not be able to get perfect near and far vision. The advertisements claim that their product will do it, but it certainly does not do it for me nor for HMBgal above!

Thanks for your honest assessment of multi-focal lenses. Would you advise people to get them adjusted so they can see far away and then just add reading glasses when looking at things close-up?

Default optomize for distance or reading?

Curlupndye: I am not sure which ways is best. It might depend on the user's needs. I was thinking I'd prefer reading and intermediate distance sharpness would be kewl as I use computer all day and read at other times. For driving, I have enough acuity to drive safely - but can't read street signs until they are close. For driving I can always get a pair of glasses (for use with the contacts) but use only when I need to do a lot of distance. By the way, I go crazy with this arrangement because people's features aren't sharp enough at 10 feet away! I have to move close to be able to see faces clearly and not mix up similar looking people. On the flip side, if you don't do much close work, you would probably prefer optimization for distance and then carry readers for when you do need to do close work.

Thanks for giving us your real-life story about multifocal lenses. Things aren't perfect for you, but it sounds like you're moving through the world quite well.

Default Got prescription change and vision is very good.

I apologize - I am now wearing Frequency 55, not the proclear lens which my OD started me with because of some astigmatism. But the good news is that I asked my OD to make the distance better for my dominant right eye. I was seeing about 20/40 with the previous prescription - this makes faces at 10 feet indistinguishable from other faces which bugged me. So today the OD modified the prescription not by increasing the strength, but by decreasing the reading part from 1.5 to 1.0. This allows the lens to deliver stronger distance correction without increasing the power. Bottom line, I can see farther now, faces are clear even at 10 feet, AND inexplicably, the reading is even better than before. The left lens prescription remained the same. At this point I think my distance vision is between 20/30 and 20/25. I can almost make out the 20/20 line on an eye chart.
This result was better than I hoped. But it took a lot of patience and persistence to get the OD to continue to refine or fix the prescription. Altogether I had 5 different fittings, and it only cost me $150. Mind you, after the 2nd fitting and prescription my OD gave me a prescription of single vision lens - which I wasn't happy with, and after a few days I got the courage to call up and ask for another fitting for multifocal lens! He reluctantly agreed to try me on multifocals - because I told him I would not wear the single vision ones -because if I am going to need readers all the time, I'd rather stick with my progressive glasses.
Thanks to all for your comments. I hope other people looking for multi-focal lens will learn from my experience.

Thanks, Calvin. It's very important to be able to distinguish faces in today's modern society, although I suppose if you had to you could conduct all of your interactions vial on-line social networking, but what fun would that be? I'm glad you found a solution for your vision issues.

That is very valuable for me just by reading Calvin's note. I am now with my 1st Multifocus contact that (give me ghosting) required reading glasses for near. Wonder how many fittings that I have to go thr'....
Anyone know what is the most effective way to find the best fit/brand?

I wish I could give you some kind of magic words to chant when looking for an eye doctor, but I don't know of any. My suggestion would be to find an eye doctor that has had many years of fitting experience and let him or her help you find the contact lenses you need.

Thanks for the good advice.

I kind of wonder why contact lens fitting is so challenging, compare to glasses (progressive). I have tried out 3-4 different type/degree lenses for the past 1 month, the search goes on...I would have stopped the search and go back to glasses which is now no more an option for me.

Now I wonder where/how to begin to get the right contact lens fitting...
Should I search for a OD in a specific discipline or OD with alliances with specific lens vendor(s) or go to OD in research/lab in the Univ to find the right fit?

Any ideas which is the right way to start?

In my opinion the most logical place to begin would be to find someone who specializes in fitting contact lenses. Let me tell you a story to show why why I think this is important.

Every once in a while I have to be hospitalized for a medical condition not related to my eyesight. Whenever I'm admitted they start an IV. The problem is I have bad veins, and starting on IV on me is kinda tricky. So as soon as they start looking for a spot to stick me, I ask for someone who specializes in starting IVs. I usually get one and it goes well.

It sounds to me like you might need the services of someone who specializes in fitting contact lenses. Try doing a search for "contact lens fitting specialist" in Google Maps. I tried it and got half a dozen results in Chicago. Let me know if this works for you.

KSN, I'm in the dark as to how to find the best OD. However, look for one who specializes in older patients - the ones that need multifocus. Fitting multifocus seems to be an art with lots of trial and error. More so than for fitting single vision lens. The problem seems to be that if the distance is good, they can't make the reading as good. They compromise, and need to take away from one (say distance vision) to improve the other (near vision.) Another piece of advise is to look for lens that have Near and Distance - I'm can't explain it but look at Cooper Vision Frequency 55. My OD prescribed Distance for the right eye (my dominant eye), and Near for the left eye to improve reading. This is giving the right eye more distance clarity, while leaving the right eye with sharper reading. This tends to give a ghosting effect, but after a while (for me about 1-2 weeks) to get used to and the ghosting goes away. I hope you find the best fit for your eyes. Regards.

Hi Calvin,

I have a new question. You started out wearing RGP lenses while most people start out with soft lenses. Why did you do it that way?

Yeah, I agree that this is an unusual route to take, Lucyfur. I don't think I've ever heard of someone switching from soft to hard contact lenses.

It looks like your patience as a patient has paid off. Congratulations, Calvin.

The problem seems to be that if the distance is good, they can't make the reading as good. They compromise, and need to take away from one (say distance vision) to improve the other (near vision.) Another piece of advise is to look for lens that have Near and Distance - I'm can't explain it but look at Cooper Vision Frequency 55.
Here's a helpful hint. If the number of your prescription has a negative sign in front of it (-) then that means it's helping you see things far away better. A contact lens prescription with a plus sign (+) in front of it means that it's helping you to see things close up.

I think I read someplace on this forum something close to this. It said that when you see a prescription with a minus sign, it means that without glasses, the person would have to pull things closer, or decrease the distance from their eyes, for them to see it clearly. The plus prescription works the opposite way. Get it?

Another piece of advise is to look for lens that have Near and Distance - I'm can't explain it but look at Cooper Vision Frequency 55. My OD prescribed Distance for the right eye (my dominant eye), and Near for the left eye to improve reading. This is giving the right eye more distance clarity, while leaving the right eye with sharper reading. This tends to give a ghosting effect, but after a while (for me about 1-2 weeks) to get used to and the ghosting goes away. I hope you find the best fit for your eyes. Regards.
Thanks Calvin for your pointers...I believe I come very close to find the right contact lens via half a dozen fittings - (beside been to 2 of my Optometric practicianers, I was very pleased to receive the fitting from a local polytechnic's optometric centre (OC) where the final yr students carried out the prescription/eye check etc with final confirmation carried out by qualified technicians/tuitors. They even gave me OCT and Hamsphere VisionFieldTest.
The OC do not have any preferences with any lens suppliers/vendors and able to provide best suitable lenses for fitting purposes. The synergies are great as the students practise what they were taught, the technicians verify and confirm the prescription, though it does take longer, 2-3hrs each session but I, the patient get the double assurances of my presc. and I do not pay for the services (I would gladly pay as it was more thorough).

I came to realise or 'visualise' the differences between Multi-focus and Single-Focus lens, I wish I had gone thr' these contact lens fittings BEFORE I underwent my IOL ReSTOR implant on my nondorminant eye.
I now fully realised what halo means, what are the compromises/trade-off of Multifocus (or rather Multi-ghosting/multi-Images) lens under different lighting conditions. I come to realised how bad the multiple-halo can be when multifocus contact lens was off prescription.

Many ODs do advise trying out the use of contact lens before monoVision IOL implants, I wonder why my OD did not ask me to try out multifocus contact lens before I had ReSTOR IOL (multifocus) selected and implanted.
I would recommend any potential presbyopia cataract IOL patient to do contact lense fittings to have a 'feel' if they like to have multifocus lens experiences.

My post-op email question to Alcon corporation did not receive any reply...I paid for 'premier lens' and I do not get to know in the product note which states "emmetropia must be targeted" until I carried out my google search after the op, and I saw in the eyetube video (Alcon live surgery in hd - unexplained IOL by Robert Osher) of a 80 yr old wife of doctor went thr' 4 IOL implants/explants by a top surgeon to get the biometry spot-on.

After one eye with multifocus IOL implanted, and most importantly, more than a dozen multifocus contact lenses fittings of various types, and realised the trade-offs for multi-focus(or called it multi-ghosing or multi-tradeoff) lenses, I wonder if FDA should suggest to Multifocus IOL manufactures to let their patients to have a feel of multi-focus experience via contact lense trial before going ahead with IOL implant. Who should be responsible for the explant bills if Emmetropia did not achieved or off the mark? What are the acceptable range etc. given that there are still 'unexplained' factor in biometry calculation? Buy an insurance to insure quality of life/vision on the specific MF IOL?

Now I am happy to find my 2 preferred contact lenses (1 for golf outting and 1 for in-door/Computer activities) according to my activity/event for that day, and one 'in-between' lens that I can do both, including driving and casual reading.
I am so grateful to the Polytech OC, that save my 2 OPs lots of time and me, lots of money for fitting services.
Thanks to those contributors like Calvin of this forum. I am sharing both my IOL and contact lens experience with the hope that others can have better way/process/feel in their selection/ decisions.

Cheers

Thanks for telling your story, KSN. I'm glad that you can still play golf and do the things you enjoy after your surgery.
