摘要：
A multi-spot ophthalmic laser device that produces spatially distributed laser spots with the spatial distribution of the laser spots defined by a spot diameter to space ratio in the range 1:2 to 1:20. The multi-spot ophthalmic laser device comprises: a laser module producing a laser pulse or sequence of laser pulses each having: a pulse duration in the range of 10ps to 20μs； a wavelength in the range 500nm to 900nm； and a pulse energy in the range 10μJ to 10mJ per pulse； and an optical beam profiling module that modifies an output beam profile of each pulse of the laser module to deliver multiple spatially distributed laser spots of defined size and energy. The multi-spot ophthalmic laser device is used in a method of improving the function of the retina of a human eye by irradiation through the cornea of the eye to the retinal pigmented epithelium by a treatment laser having a beam profile with spatially distributed energy peaks.
