LASER APPARATUS FOR TREATMENT OF A CATARACTOUS LENS |
摘要 |
An apparatus for microdisruption of cataracts in lens tissue by impulsive heat deposition comprising : a source of pulsed laser radiation, a user input device, a control circuit, and an optical waveguide configured to transmit the pulsed laser radiation. The light intensity which exits the optical waveguide has a wavelength selected to match an absorption peak of at least one component of the lens tissue, a pulse duration time shorter than a time required for thermal diffusion out of the laser irradiation volume and shorter than a time required for a thermally driven expansion of the laser irradiated volume, and a pulse energy resulting in a peak intensity of each laser pulse below a threshold for ionization-driven ablation to occur. |
