Paper Abstract

In this paper, we present theoretical model which treats the effects of pulsed laser irradiating ocular tissues. The effects involve both thermal damage and mechanical damage. The thermal effect is the energy absorption, depositing and heating in ocular tissues. This results in a non-well-distribution temperature field. As the deposited energy increasing, the melting, vaporization, and recoiling-loading of the ocular tissues would be produced. This produces the shock waves of high pressures and the shock propagate in the ocular tissues. The shock front would produce reflectance and transmission in the back front of the ocular tissues, and this results in a mechanical damage in the ocular tissues.
