Ditto everything Hot Ptah said. I've worked in Ophthalmology since the first generation multifocal lens was in its trial phase; the practice I was with was one of the principal investigators. I currently work at a practice where our chief surgeon trains other physicians in the technology and technique of multifocal refractive surgery.The most common problem that I have seen over the years with any new technology is when the patient has unrealistic expectations, that their vision will be "perfect" at distance, intermediate, and near, as well as poor patient selection by the physician. While some patients achieve "perfect vision", a lot do not because of pupil size, amount of astigmatism and the patient's personality in general. (One patient's "perfect vision" is another patient's "not acceptable" vision, depending on how they view the world in general)
Some lenses correct different focal lengths better than other lenses; some lenses will cause more halos and glare at night because of the size of the optics. I agree that it's imperative that you have your evaluation and surgery done by someone with years of experience who uses the latest wavefront technology. They will be able to assess which lens will be appropriate for your particular visual system, or be able to tell you if you would not be a good candidate, which is, in my opinion, the most important assessment of all.
BTW, Hot Ptah, we had a patient who was an artist a few years ago who painted what she "saw" while having cataract surgery. It was some of the most beautiful images/colors/patterns I have ever seen.
