  • Optical filter on contact lens surface
    Patent number: 11439536
    Abstract: A contact assembly (301,400) for laser surgery may include a contact lens (402) and an optical filter (404). The contact lens (402) may be configured to be positioned in an optical path of therapeutic radiation (310) directed at an eye (100) of a patient. The optical filter (404) may be coupled to an outer surface (402A) of the contact lens (402). The optical filter (404) may be transparent to the therapeutic radiation (310) with a first wavelength and may be opaque to radiation (318) with a second wavelength different than the first wavelength.
    Type: Grant
