Title: Nivedan Tiwari: Innovator in Intraocular Lens Technology

Introduction

Nivedan Tiwari is a prominent inventor based in Irvine, California, known for his contributions to the field of ophthalmic devices. He holds two patents that showcase his innovative approach to intraocular lens design. His work focuses on enhancing visual acuity and depth of focus for patients undergoing cataract surgery.

Latest Patents

Tiwari's latest patents include a "Distance Dominant Intraocular Lens" and an "Intraocular Lens Having an Extended Depth of Focus." The Distance Dominant Intraocular Lens features a base refractive structure with anterior and posterior surfaces designed to produce a first optical power. It incorporates a diffractive structure that includes overlapping first and second diffractive patterns, which generate second and third optical powers. The second optical power is an uneven division of the third optical power, with step heights that vary based on radial distance from the optical axis.

The Intraocular Lens Having an Extended Depth of Focus comprises an optic with anterior and posterior surfaces that provide a refractive base power. One of these surfaces has a profile with steps determined by combining three constituent diffractive profiles. Each profile corresponds to different optical powers, all of which are positive and less than about 1D or about 1.25D. The combined profile is defined by a function that maximizes the diffractive profiles, ensuring optimal performance.

Career Highlights

Throughout his career, Tiwari has worked with notable companies such as Tatvum LLC and Bausch & Lomb Incorporated. His experience in these organizations has allowed him to refine his skills and contribute significantly to the development of advanced intraocular lens technologies.
