This IOL simulator compares the optical performance of standard monofocal intraocular lenses with extended depth of focus premium IOLs using the actual optical principles underlying each design, not a simple visual filter. By modeling how these lenses distribute focus and affect contrast across distances, it highlights the tradeoffs between clarity, range of vision, and optical side effects, making IOL differences more tangible and easier to understand before surgery.
