IN VITRO EXPERIMENT STUDY ON ABLATION PARAMETERS IN FEMTOSECOND LASER-OCULAR TISSUE INTERACTION
In order to apply femtosecond laser technology in ophthalmology, especially in glaucoma treatment, femtosecond laser-ocular tissue interaction research was conducted. Focusing angle, output power, irradiance duration are three important laser parameters for ophthalmic microsurgery. In our work, the relationship of the three different laser parameter versus cutting effect was investigated respectively by an in-vitro experiment using an 800 nm-wavelength 150 fs-pulse-length laser system. This experiment aims to minimize the effects of thermal damage, while at the same time maximizing the speed or quality of the tissue ablation process. The experiment result shows that there is a great potential to optimize the surgical effects using femtosecond laser compared to that using a longer pulse laser.
