Methods and apparatus for presbyopia treatment using a dual-function laser system

摘要: Presbyopia is treated by a method which uses various lasers to remove portion of the scleral tissue and increase accommodation presbyopic patient's eye By changing laser power density, fluency or spot size, single device having dual-function ablation coagulation proposed for minimum bleeding. Fiber-bundle coupled fiber presented density efficient New mechanisms lens curvature change anterior shift are total accommodation. The preferred wavelength ranges from ultraviolet infrared including (0.15-0.36) microns, (0.9-1.6) (1.8-2.2) microns (2.8-3.2) Both scanning delivered systems proposed.
