Medical Forum / General / Vision / January 2009Multifocal silicon hydrogels?
Are the Purevisions still the only multifocal silicon hydrogel contact lenses? Or did some new models come out recently Thanks in advance for the info. > Are the Purevisions still the only multifocal silicon hydrogel contact > lenses?

I recall reading on this board months ago that others were on their way.

How does Ciba Focus Progressives compare to Purevisions? In any respect, from comfort to vision acuity. How does Ciba Focus Progressives compare to Purevisions? In any respect, from comfort to vision acuity. I don't know, as I never tried the Focus Progressives. However, that is off-topic, because the FPs are not Si-Hy (afaik). Sure wish Ciba would make a Night and Day Progressive! PS- Since the silicon hydrogel materials are obviously so much superior to other soft lens materials, much better for eye health, etc., I'm surprised that the other materials are still made and prescribed. > How does Ciba Focus Progressives compare to Purevisions?

At some point, nearly every material was "superior to other materials." Every material has pros and cons. True that SiHy has better permeability, but some people get heavy deposits they don't see with plain old polymacon. Plus, some people have been through several brands and shapes trying to find a comfortable fit. If none of the SiHy lenses were as comfortable, would you make them switch? -MT >> How does Ciba Focus Progressives compare to Purevisions? In any >> respect, from comfort to vision acuity.

Over that time period, my OD switched me several times, as the industry went from vial contacts, to quarterly and then to monthly, discontinuing the ones I was currently wearing. I believe that I was an easy patient, tolerating most contacts well and finding them easy to adapt to. Still, if I had something that was working, I wasn't about to change without a good reason. One factor, is that it appears that N&D is twice as expensive.

However, I'm still surprised that in 2009, there is still only one multifocal silicon hydrogel lens available, and no multifocal toric si-hy lens. Anyone here know, if something new will be coming out soon? |
