Medical Forum / General / Vision / July 2006IOL 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. > Is a particular IOL brand considered the best in terms of safety (e.g., > complications such as secondary cataract, etc)?

I think it might depend more on what the surgeon is accustomed to using, and would go with his/her recommendations. I do think a relatively sharp edge design is better for preventing sec. cat., esp. if the surgeon polishes the posterior capsule. I have Technis IOLs and they are great because they also correct spherical aberration (there are now a few brands that do that). Most importantly, I would not let a surgeon talk me into a multifocal IOL or a focus changing design. w.stacy, o.d. <snip> > Most importantly, I would not let a surgeon talk me into a multifocal IOL > or a focus changing design. > > w.stacy, o.d. Could you elaborate a bit? Thanks 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. w.stacy, o.d. ><snip> > [quoted text clipped - 11 lines] > > Thanks for your input.
