  • Patent number: 11896528
    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.

  • Patent number: 11890231
    Abstract: An ophthalmic surgical laser system includes a laser beam delivery system having multiple moving components for scanning a laser focal spot in a target eye tissue, where the motors that actuate some of the moving components are equipped with respective digital encoders that measure actual motor positions. A controller controls the laser beam delivery system to perform a treatment scan, while recording the actual motor positions from the encoders. Using the actual motor positions and a calibration relationship between actual motor positions and delivered laser focal spot positions in a target tissue, a laser cutting pattern is digitally reconstructed, which represents the incisions actually achieved by the treatment scan. The reconstructed laser cutting pattern may be visually inspected and further analyzed, e.g. to compare it to the intended laser cutting pattern used to execute the treatment scan, to calculate the achieved refractive correction, or to simulate tissue resetting.

  • Patent number: 11660231
    Abstract: A method for a minimally invasive, cell-selective laser therapy on the eye. The method, based on a short-pulse laser system, allows for different selective types of therapy on the eye. The method is based on a frequency-doubled, continuously working solid-state laser including a pump source and a control unit. The control unit regulates the pump source such that the solid-state laser emits individual pulses with pulse lengths ranging from 50 ns to continuous, wherein pulse lengths ranging from 50 ns to 50 ?s are provided for selective therapies and pulse lengths ranging from 50 ?s to continuous are provided for coagulative or stimulating therapies, in particular in the range from 1 ms to 500 ms. The proposed method enables a selective treatment of melanin-containing cells in the different areas of the eye via the targeted control of the pump source.

  • Patent number: 11642244
    Abstract: A system for treating an eye includes a laser light source providing photoactivating light. The system includes a scanning system to receive the photoactivating light as a laser beam and to move the laser beam over a cornea treated with a cross-linking agent. The system includes a controller that provides control signal(s) to programmatically control the laser light source and the scanning system. The control signal(s) cause the laser beam to visit region(s) of the cornea more than once according to a scan pattern and expose the region(s) to the photoactivating light. The photoactivating light causes the cross-linking agent in the exposed region(s) to react with oxygen to generate cross-linking activity in the exposed region(s). The scan pattern causes a predetermined period of time to pass between visits by the laser beam to the exposed region(s), the predetermined period of time allowing oxygen in the exposed region(s) to replenish.
