Cooper Torics with Base Curve of 9.0

IanB · #1 (**permalink**) 02-06-2010, 02:45 PM

I currently wear Cooper Torics with a Base Curve of 9.0 which are made to order. However my optometrist tells me you can buy 'off the shelf' Cooper Torics that would be suitable (I have a CYL reading of -5.00). I can't find these on-line; any thougts? Thanks

Hello IanB

Welcome to Lens101 forum.

I had a look on the various websites but could not find Cooper Torics in your Base Curve or anywhere near your cylinder correction.

The nearest I have found are Coopervision Hydrasoft. There are a number of different lenses on this website, but I don't know the differences between them.

http://www.visiondirect.com/la/product/default.asp?pid=214866&catid=11889&aid=337021&apar am=hydrasoft_toric_options_&CAID=bef991b8-91c8-4363-92c0-07a0df806ae5

However, they seem expensive (they are 3 monthly disposable lenses) and come in a pack of 4 (i.e. 6 months supply).

I would guess others on this forum may know of other sources where you can buy the lenses you want.

Do you have to have the Cooper Toric lenses, or would another Coopervision brand or even another manufacturer be acceptable?

Copper Toric is a vial lens. lens.com cost is 65 /lens It's available with a base curve of 8.4 or 8.7 I assume your OD is saying a base curve of 8.7 is close enough. The same lens is available in a 4 pack marketed as Preference. It's intended for quarterly replacement and costs around $100 for the 4 pack.

There may be other lenses that work for you, depending on what the other parameters of your script. Give your entire script and some posters may have some other suggesions.

Why not have your doctor order a bunch of trial lenses?

edited to ask are you saying your cylinder is -5.00? You'll need the preference XR lenses (extended range). The cost is a little higher. Check the websites, any lens that says XR might be available.

Hi lurker2010.

I just want to say that I'm impressed at how helpful you're being to IanB. It's good to see people on Lens 101 willing to "go the extra mile" to help someone who posted a question. I wish I new a little more about contact lenses so I could be as helpful, but I'm glad you have an answer for IanB and I hope he or she finds it useful.

Yes, I'd agree. That should be very helpful to IanB.

I don't know what country the OP is from but I think we're missing something (at least if the OP is from the US). The OPs optometrist told him he could use a copper toric lens off the shelf. That requires a script written the by the optometrist. The optometrist should know, or could easily determine, which cooper vision lens is appropriate, order a trial lens and then write a script if the lens works.

A change in the brand of lens, particularly with a change in base curve from 9 to 8.7, would require a new script. The preference XR lens would probably be made to order.

There are a variety of lenses that might be available. The OP should be looking at trying different lenses and not just trying to get a script for a similar lens to what's he's now wearing.

Hello. Please excuse my ignorance, but what is an "OP"? Some people like to abbreviate "eye doctor" as "OD." Is it pretty much the same thing?

OP= "original poster"

Thanks Lurker2010. I guess it has nothing to do with eye doctors as Frodo suggested. It's got more to do with forums and it seems like a handy dandy term.

Thanks, Lurker2010. I guess I should have found that on Forum Posting 101, as it seems pretty basic. I'm a better poster for it.

I thought "off the shelf" was the opposite of "custom made." Most RGP lenses are custom made, or so I've heard, so I would think that soft toric lenses like Cooper Toric will require a prescription, but because the lenses are all mass produced in different prescriptions like T-shirts they would be "off the shelf." Am I right?

That's going to depend on whose shelf you are talking about. I would think, as you stated, that the majority (not all) of soft lenses will be produced in batches and held in stock by the manufacturer. The optician will stock the common spherical powers, but it gets difficult logistically to stock all the variants for toric lenses.

RGP lenses (in my case Menicon) seem to be held in stock by the manufacturer in increments of 0.5mm base curve and probably three different diameters, but again I would be surprised if they could stock every variant of axis and cylinder power for torics, so perhaps these are 'made to special order'.

Thanks for your insight, Knotlob. I heard, like Railfan up there, that all RGP contact lenses are custom made. Did I miss something?

I based my statement on the Menicon RGP lenses. I wear Menicon Z Alpha and their product catalogue (which is in their professional area) shows the lens is available in 0.05mm increments of base curve (6.5-9.0mm) and actually 8 different diameters (8.8-11.0mm). i.e. the sizes available are set incrementally so that doesn't sound like it's made to measure - you cannot get a base curve of say 7.27mm - but you can have 7.25 or 7.30mm. So I would think that Menicon try to keep a range of lenses in stock at a central location in each country. It certainly didn't take longer than 3 days to get my lenses once the optician ordered them.

Some of the soft toric lenses, particularly the extended range lenses, are made to order. The Proclear Toric (including XR) is available in over 45,000 different prescriptions. Not every combination is stocked, even by CV. Maybe when the mfg makes lenses to order they make some extras to keep in stock.

Yes, I agree that when you start adding the possible combinations for each available cylinder axis and power, the stock logistics become extraordinarily difficult, especially if there is an expiry date on the lenses.

But there must be a trade off, as some customers will not appreciate waiting long while a production run for their prescription is scheduled.

So they're not totally custom made to fit you exactly, but they have a whole lot of sizes so you will probably get a pair of contact lenses that fits very well. To use the time-tested shoe analogy again, it's like a shoe store that offers half-sizes like 9 1/2 instead of just the whole numbers, right? So if my shoe size is 9.45 I could wear the more comfortable 9.5 rather than the 9 or ten. Is it something like that?

Yes, but your shoes would also probably have to be available in different width fittings as well

This is the 18th reply that you've gotten to your question about finding the right size Cooper Torics. Did you find this thread helpful at all? We got off on a slight tangent but then got back on the track. Has this thread helped you find contact lenses that are suitable for you?
