• •Intraocular lenses (IOLs) replace the eye's natural lens during cataract surgery.
• •IOLs now offer various designs, including monofocal and presbyopia-correcting lenses.
• •Advanced simulations and visual simulators are being developed to aid in IOL selection.
• •University of Rochester researchers have made significant contributions to IOL technology.

More than 30 million people globally undergo cataract surgery annually, and recent advancements in optics, ophthalmology, and AI have led to rapid improvements in intraocular lenses (IOLs). These IOLs have evolved to mimic natural human lenses, with options like monofocal and presbyopia-correcting lenses, including toric designs to correct astigmatism. Researchers are developing advanced simulations and visual simulators to help patients and surgeons choose the right IOL and accelerate the process of bringing new products to market. Faculty, students, and alumni from the University of Rochester have led advancements in IOLs for decades.
