Title: Victoria Piunova and Advances in Light-Adjustable Intraocular Lenses

Introduction

Victoria Piunova is an inventor associated with RxSight, Inc., in Los Gatos, California. Her patent work addresses light-adjustable intraocular lenses designed to help control optical power changes during lens adjustment.

Latest Patents

Piunova is named on one patent, “Light Adjustable Intraocular Lenses with Advanced Polymerization Control.” The invention describes lenses that use shaped illumination to activate a photoinitiator, prompting polymerization of a mobile macromer and thereby changing the lens’s optical power.

The design combines a polymer silicone network with a mobile macromer, ultraviolet absorbers, a photoinitiator, and a front protection layer. Its polymerization-control approach is intended to suppress unintended optical power drift. The patent also describes options such as radical scavengers, sterically hindered or monofunctional macromers, and switchable or anchored photoinitiators.

Career Highlights

Piunova’s listed patent reflects work on materials and processes for adjusting intraocular lenses with light. The invention specifies operating conditions involving oxygen concentration and the balance between oxygen-driven photoinitiator quenching and photoinitiator-driven polymerization.

Collaborations

The supplied information lists Ilya Goldshleger and John Kondis as Piunova’s coworkers. Their inclusion provides context for her professional connections, though the information does not specify their roles in the patent.

Conclusion

Victoria Piunova’s patent focuses on improving control and stability in light-adjustable intraocular lenses through polymerization design and material choices.
