E W CATARACT 42 February 2014 satisfaction. Careful consideration and education is required to weigh the variations in design and material composition against the desired outcome. The key to premium outcomes is a comprehensive under- standing of how the differences in biomaterials and design alterations factor into successful outcomes. For my patients, I prefer a hy- drophobic acrylic IOL with a 360 posterior square edge on the optic, a negative spherical aberration value, and a high Abbe number. I select a lens free of glistenings with UV light blocking, but without blue light blocking. Currently, the Tecnis family of lenses (Abbott Medical Optics, Santa Ana, Calif.) is my first choice.
