Determination of elastic characteristics of cataractously changed lenses in the experiment

Abstract

The purpose of the investigation is the definition of numeral meanings of the Young’s module on the central part of cataract in vitro. The experiment was carried out by the method of penetration on 108 lenses of a human eye with the help of the developed original device. It is revealed that the area of resilience display is within small limits of unit strain. The Young’s module is within 2 MPa to 6 MPa and depends on the density of a lens nucleus (III—V) according to Buratto.
