IOL optics and quality of vision make in trying to attain this goal. The second trend is the advancement of diag- nostic and surgical technologies that are helping to tighten the standard deviation in cataract surgery, bringing more eyes to 20/20 or better visual acuity postoper- atively. As quantity of vision edges closer to the goal, it may be time for renewed emphasis on quality of vision. By considering important material and design features like refractive index, spherical and chromatic aberration, glistenings, and chromophores, we can make choices in clinical practice that improve both quantity and quality of vision. For this supplement, I have assem- bled a dynamic group of experts in the field to explore the principles of optics that contribute to high quality of vision and patient satisfaction. I n evaluating IOLs, surgeons typically think about the lens material and design from a structural perspective: How stable is the lens in the bag? Does the edge prevent lens epithelial cell migration? Less often, perhaps, do surgeons consider how the lens material and design affect image quality. Our attention was first drawn to image quality several years ago, when spherical aberration garnered a signifi- cant amount of attention. The result has been the popularization of aspheric IOLs, to the benefit of our patients. Two important trends are now changing how we think of cataract surgery. The first is presbyopia-correcting IOLs. The desire to achieve youthful vi- sion for a spectacle-independent lifestyle has raised expectations and increased awareness of the visual tradeoffs we Daniel H.
