3D model analysis of the temperature dynamics during a welding process is presented. Bio-heat equation described laser-tissue interaction in porcine and human eyes, simulating the surgery conditions.

The modeled behavior of the superficial cornea temperature was compared with direct measurements performed by an infrared thermo-camera.

The results indicated a selective, spatially-confined heating effect, at temperatures close to denaturation points of the stromal collagen.
