As I mentioned, normal cataract lens replacements are monofocal and usually set for distance. The 'Crystalens HD' is an accomodating lens by having some extra tabs around it that shifts position about 1 milimeter (about one twentyfifth of an inch) forward or backward to focus. I looked real hard at them and read every forum I could find on the net about experience. While some worked well (and I'm glad yours did), others tended to shift position or not focus well at all. I also had long discussions with my eye surgeon who had done several of them. Setting aside the expense (which was not an issue in my case), I felt the risk was too high for the limited benefit.
I'm amazed at how well I can read even without the 'Crystalens HD' type of accomodating lens. There is another variety called "multifocal" which is like a circular bifocal which should probably be avoided at all costs as the posted experience in forums has generally not been very good.
swampsniper: In any event, ask lots of questions and read all the forums you can find before you go with anything other than a normal monofocal lens.
