Philadelphia Cataracts Surgeon – Dr. James S. Lewis
Serving Delaware Valley, Montgomery County, Warminster, Conshohocken, Phoenixville and King of Prussia
The word “Cataract” can evoke undue concern and trepidation. Instead, cataract surgery should be viewed as an opportunity to regain lost vision and, in many cases, improve it. As a leading Philadelphia cataract surgeon, Dr. Lewis is committed to exploring the risks, benefits and alternatives with each cataract patient when providing the most common and most successful surgical intervention of the modern era.

nanoFLEX DCB for Near and Intermediate Vision
nanoFLEX is a premium intraocular lens implant (IOL) manufactured by STAAR Surgical, a small high-tech company known for creating the field of small incision, sutureless cataract surgery. Their introduction of the first foldable intraocular lens in the early 1990’s was just one of their groundbreaking contributions to ophthalmology. STAAR developed the STAAR Toric for the correction of astigmatism almost a decade before Alcon, the “800 lb. gorilla” in the field of ophthalmology. STAAR also developed
the Visian ICL, an intraocular lens to compete with LASIK.

So, we gathered together the names of surgeons we knew were educating their colleagues about the topic at Hawaiian Eye, Kiawah Eye, OSN New York and AAO; conducting research to optimize patient clinical outcomes; digging into the diagnostic technology to assist in selecting the best patient, and the best lens for that patient; looking into the unique business aspects of premium IOL surgery; and, of course, the early adopters who saw great promise in the IOL technology.
