Revolutionizing vision Correction with Femtosecond Lasers

Len Zheleznyak, Clerio Vision

Abstract

The eye's refractive error is typically corrected with spectacles, contact lenses or by modifying the shape of the cornea (e.g. LASIK). In this talk, we will explore the application of femtosecond lasers for modifying the refractive index of contact lenses, intraocular lenses and even the cornea itself. By modifying corneal refractive index, as opposed to changing surface curvature by removing tissue, we are able to correct the eye's aberrations safely and non-invasively. We will also discuss applications in contact lenses and intraocular lenses implanted following cataract surgery.

About the speaker

Len Zheleznyak is Vice President of Vision Science at Clerio Vision. He is currently developing non-invasive methods of correcting refractive error in the human eye using ultrafast laser phenomena to modify refractive index. Len’s previous research interests include presbyopia correction, intraocular lens design and developing adaptive optics systems to study the visual system. He completed his PhD in Optics from the University of Rochester in 2014. Prior to his doctoral work, he developed photonic devices for optical inspection of pharmaceuticals at Ometric Corporation, a start-up company spun out of the University of South Carolina, subsequently acquired by Halliburton Energy Services. Len has authored numerous peer-reviewed journal articles, book chapters and patents relating to vision and optical science.
