On Wednesday August 24th, 2016, Dr. Hamilton performed cataract surgery and implanted the first ever Symfony intraocular lens (IOL) in Los Angeles. The Symfony lens is a revolutionary and recently approved intraocular lens (IOL) that is able to provide a continuous range of vision without glasses for cataract patients. This IOL is the first of a new class of lens implants called Extended Depth of Focus (EDOF) IOLs. The lens uses diffractive optics in a way similar to what is used for the most advanced photographic lenses to reduce color dispersion (the rainbow spread of light through a prism) that can significantly degrade quality of vision. It also uses diffractive optics to create an extended focal range of continuous vision from distance up to about 66 cm (26 inches). This IOL, having already been used extensively in Europe and other parts of the world, recently gained approval by the FDA after rigorous clinical trials. It comes in a toric version as well which allows for the simultaneous treatment of astigmatism, an optical imperfection that degrades the quality of vision. Dr. Hamilton believes revolutionary EDOF IOLs, like the Symfony lens, will bring incredible vision to a wide range of eligible patients and become a staple for cataract surgeons nationwide.
