Monitoring and animation of laser ablation process in cataracted eye lens using coherence tomography

Optical coherent tomography (OCT) enables one to follow the pulse-to-pulse kinetics of laser interactions with turbid biological tissues. In experiments we investigate the effect of free running mid infrared laser radiation of different wavelengths on a cataract-suffered human lens in vitro. Different regimes of laser ablation and preablation surface transformations are monitored in situ.
