Medical Forum / General / Vision / September 2006Frequency 55 vs. Focus Monthly lenses
Hi: I am about to order new lenses, and would like to get the "best all around" lenses that do not cost too much. I am -2.25 / -2.25. I wear my lenses 12-14 hrs/day, lots of computer work. At this point, I am considering Coopervision Frequency 55 and Ciba Focus Monthly lenses. a) Is either one a better lens and why? (the F55s are cheaper) b) I have a trial pair of the F55s with Base Curve shown as "MED" and seem to fit fine, but order forms show 8.4, 8.7, or 9.0 available... Q: which is equivalent to the MED curve? 8.7? c) Any other lenses that I should consider? Thanks in advance! -- Paul there are literally hundreds of lenses like the ones you are considering. if they feel comfortable to you, and you see well with them, and the eye doc says they fit you, then they will work fine for you in the way you intend to wear them. typically these brands of lenses are not the least expensive brands, at least where i live (midwest US). there are very similar lenses that are more aggressively priced by the manufacturer. i would try lenses made by biomedics (e.g. biomedics 55) and vistakon (acuvue 2). you are right. MED = base curve 8.7 --------------- > Hi: > [quoted text clipped - 16 lines] > > -- Paul >Hi: > [quoted text clipped - 6 lines] > >a) Is either one a better lens and why?

Old style HEMA SCLs are never a first line choice for me; they are only used when I have to. The cheapest ones are the Ciba O2Optix and the Acuvue Advance. > Hi: > > I am about to order new lenses, and would like to get the "best all around" > lenses that do not cost too much.

Given that you wear them most of the day and work in potentially drying condidtions, why not treat yourself to the best lens that fits you instead of concentrating on price. Better lenses would cost under $50 more per year -- less than $0.25 a day. > At this point, I am considering Coopervision Frequency 55 and Ciba Focus > Monthly lenses. These lenses are very similar, 15 to 20 year old material and design. > a) Is either one a better lens and why? (the F55s are cheaper) The best lens is the one that fits and performs best on your eyes. > b) I have a trial pair of the F55s with Base Curve shown as "MED" and seem > to fit fine, but order forms show 8.4, 8.7, or 9.0 available... Q: which is > equivalent to the MED curve? 8.7? When your fitter writes the prescription this will be specified. > c) Any other lenses that I should consider? Ask your fitter about the newer silicone hydrogel lenses or Benz material lenses. You will need a prescription from your fitter to order lenses. Dr Judy "Ask your fitter about the newer silicone hydrogel lenses or Benz material lenses. " Just wanted to comment on this--I wear the Extreme H20 lenses, and they work well for me (I have dry eye), but I noticed from the beginning that I needed more minus power in this brand--to achieve the same acuity as in other brands. Has anyone else noticed this? I wonder if people just trying these lenses for the first time would find them "weak" and vision blurry as I did, and give up on them for that reason. Thanks, C66 > "Ask your fitter about the newer silicone hydrogel lenses or Benz > material lenses. " [quoted text clipped - 10 lines] > Thanks, > C66 The correct lens power for any given brand/design/fit is determined while the lens in on the eye. It is not unusual for someone to need + or - .25 or so difference from one brand to another. The only way to get "weak" blurry vision is if the lens is incorrectly fitted and prescribed, like basing it on a spectacle correction and not checking the visual acuity and adjusting it appropriately. LB, O.D. As others have said, while it is true that the silicone hydrogel lenses are superior to the older HEMA based lenses that you are trying, they should still work fine for you since you don't plan to wear them for excessive periods of time and they are comfortable to you. they are also less expensive which seems to be a concern for you. If you want the healthiest lens for your eye at the best price for those lenses, then I agree that 02 Optix or Acuvue Advance is the best choice. thanks but... I just tried some CIBA O2 Optix for 3 days and was disappointed: - made my eyes sting and go bloodshot - vision was somewhat blurry, noticeably worse than w. Freq. 55s - expensive - PS: I use ClearCare sol'n, which I have been for a year w. no problems QUESTION: what about Coopervision Biocompatibles? (vs. silicone hydrogels).. I used these for 3 years no problems, but was hoping to switch to cheaper lenses (they are priced same as the expensive vs. silicone hydrogels) thx! > As others have said, while it is true that the silicone hydrogel lenses > are superior to the older HEMA based lenses that you are trying, they [quoted text clipped - 5 lines] > those lenses, then I agree that 02 Optix or Acuvue Advance is the best > choice. NOTE: Coopervision Biocompatibles a.k.a. ProClear thx > thanks but... > [quoted text clipped - 20 lines] >> those lenses, then I agree that 02 Optix or Acuvue Advance is the best >> choice. the aspheric design of 02 Optixs also causes blur for many patients. some docs deliberately overminus patients a little to reduce this complaint. Biocompatible is a good lens. You should try Biomedics XC which is very similar and less expensive. I have had lots of patients who are very satisfied with these lenses and pick them over silicone hydrogels in side-by-side comparisons. ================ > thanks but... > [quoted text clipped - 20 lines] > > those lenses, then I agree that 02 Optix or Acuvue Advance is the best > > choice. seems the Biomedics XC are described as a 2 week lens on the Coopervision site... I understand Proclear/Biocompatibles are 1 month.... so, does that mean I will go through the XCs twice as fast? ao, are they both OK for 1 month seems that Coopervison makes both, but the XCs are definitely cheaper thx! -- Paul > the aspheric design of 02 Optixs also causes blur for many patients. > some docs deliberately overminus patients a little to reduce this [quoted text clipped - 31 lines] >> > those lenses, then I agree that 02 Optix or Acuvue Advance is the best >> > choice. >thanks but... > >I just tried some CIBA O2 Optix for 3 days and was disappointed: >- made my eyes sting and go bloodshot That can happen as people go from traditional (HEMA) soft contact lenses (SCLs) to silicone hydrogel (SHCLs) lenses, as their eyes get used to getting so much more oxygen. That typically goes away in less than 1 week, although in one EW SCL abuser it took around 2-3 weeks before she felt comfortable in then. This "problem" is pretty much IMHO exclusive to those who go from HEMA SCLs to SHCLs and not to "virgin" eyes. >- vision was somewhat blurry, noticeably worse than w. Freq. 55s (1) Very picky people with (2) oily tear films sometimes notice this, although I find it to be rare. >- expensive ??? Cost *per lens* (Frequency 55 is a monthly replacement SCL, O2Optix are every two weeks with daily wear [DW]) is about the same. IOW, cost is about 2X more for O2Optix, but you get twice the lenses. >- PS: I use ClearCare sol'n, which I have been for a year w. no problems > >QUESTION: >what about Coopervision Biocompatibles? (vs. silicone hydrogels).. I used >these for 3 years no problems, but was hoping to switch to cheaper lenses >(they are priced same as the expensive vs. silicone hydrogels) SHCLs are my lens of choice for EVERY SCL (save daily disposable because none are available) patient. Although for low power successful SCL patients without any contact-lens related complications, the benefits might be hard to see. If you are looking for cheap lenses, look at the B&L SofLens 59 or the Ciba Choice AB lenses. I find them to be garbage and never use them, but if cost is your overriding issue, then they may be worth looking into. |
