Abstract
An ophthalmic laser treatment delivers patterned laser energy to an eye of a patient. A pattern-scanning laser device of the laser treatment system includes a laser module, a scanning module and delivery optics. The laser module generates laser energy (e.g. via a green laser diode), which is directed to the scanning module via a fiber optic cable. The scanning module produces the patterned laser energy by reflecting the laser energy into the delivery optics at different angles via a dielectric MEMS scanning mirror. The delivery optics includes an F-theta lens, a motorized and wirelessly-controlled spot-size selector module, and a focusing lens. A mobile computing device receives parameter information via a graphical user interface or voice control and sends the parameter information to the pattern-scanning laser device. In response to receiving activation signals from an activation unit, the pattern-scanning laser device emits the patterned laser energy based on the parameter information.
