IOL with the best track record?

Is a particular IOL brand considered the best in terms of safety (e.g.,
complications such as secondary cataract, etc)? I'm having cataract surgery
on 8/09 and will meet the surgeon on 7/31. I just want to know if a
particular brand stands out among various IOLs.

I think the evidence shows that the focusing lenses, like the
crystallens don't really give much "accommodation" if any, and to
implant that bulky hinged lens without hope for much focusing, is bad
medicine, imo.

Re the multifocals, all multifocals cause more light scatter than the
equivalent single vision lenses, which obviously will compromise night
vision, at least. Also, less than half the incoming light will be in
focus at any particular viewing distance, which is why reading in dim
lighting (e.g. in a restaurant, etc.) is not any where near as good as
with single vision iols plus spectacle readers).

If the patient absolutely refuses to wear supplemental glasses under any
circumstances, then multifocal iols may be indicated, but I think that's
a rare patient who has to be fully informed that the vision will not be
perfect at any distance whatsoever.

Most importantly, I would not let a surgeon talk me into a multifocal IOL
or a focus changing design.

Could you elaborate a bit?

Thanks
