Speical Biophysics Seminar - Presented by the School of Physics:  Dr. Barry Belgorod, Weill-Cornell Medical College

The human crystalline lens is one of only three tissues that are transparent to visible wavelengths of light. To understand its function in the visual system, it is important to have a grasp of its embryology to learn how it develops, its anatomy, including ultrastructure, its physiology, metabolism and mechanisms of homeostasis and its function as an active optical element. Comparative anatomy will highlight aspects of lens evolution and alternative adaptations in other species. Pathology of the lens will address abnormalities in lens shape, position, metabolism, refractive index, clarity and degeneration with age and other degradative factors.

About the speaker: Barry Belgorod, MD, FACS has been on the faculty of the Weill-Cornell Medical College for over three decades. He lectures in Ophthalmology at the Perelman School of Medicine at the University of Pennsylvania. He performs micro-surgery of the eye, including surgery of the crystalline lens. He holds patents on electro-optical devices, including highly-afocal laser delivery systems for laser vision correction.
