Patent ID: 8728062

Claim:
A device for controlling laser therapy of an eye, comprising: an evaluation unit that determines an intensity of a transient temperature effect in the eye by analysis of interferometric signals obtained from the eye; and a control unit that controls a laser that applies the laser therapy, which is based on said transient temperature effect, the control unit being operably connected with said evaluation unit; an OCT and wherein said interferometric signals are OCT signals, and further wherein the analysis comprises Doppler analysis (DOCT); wherein the evaluation unit is configured to determine a temperature distribution according to the following relationship: T ⁡ ( x , y , z , t ) = α ⁢ Ω ⁡ ( x , y , z , t ) · 3 ⁢ η ⁢ ⁢ a ⁢ ⁢ λ 0 2 ⁢ 16 ⁢ π ⁢ ⁢ k b wherein Ω is the Doppler frequency spread determined by DOCT; wherein k b is the Boltzmann constant; wherein η is a dynamic viscosity of a medium; wherein a is a particle diameter; wherein λ 0 is an OCT spectral centroid; and wherein α is a material characteristic.
