Topic: Recent Advances in Vision Science

Speaker: Len Zhelenznyak


In its evolution from a military technoligy, to astronomy, and finally to vision science, adaptive optics has enabled scientists to uncover fundamental mechanisms of sight, monitor drug efficacy, and produce stunning in-vivo images of hitherto hidden retinal structure.  In this talk, Len will discuss the key concepts behind adaptive optics and wavefront sensing. We will subsequently explore recent high-impact applications of adaptive optics in vision science. 


 Len Zheleznyak is a Research Associate at The Institute of Optics, University of Rochester and VP of Vision Science at Clerio Vision, Inc. 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.
