    Abstract: In certain embodiments, a system for aligning an eye with a patient interface of a laser device includes a camera, a display screen, and a computer. The camera records images of the eye through the patient interface of the laser device. A liquid is disposed between and is in contact with the patient interface and the outer surface of the eye. The images include an outline of the liquid. The display screen displays the images of the eye. The computer aligns the eye with the patient interface by: identifying the outline of the liquid in an image received from the camera; determining a misalignment of the eye according to the outline; and instructing the display screen to display a description of the misalignment.

    Abstract: An ophthalmic speculum includes arms, a locking mechanism, and an air-flow system. The arms include a first arm and a second arm. Each arm has a retractor shaped to conform to an eyelid of a pair of eyelids of an eye. The retractors are substantially symmetrical about a lateral axis. The locking mechanism is coupled to the arms. The locking mechanism moves the arms to allow the retractors to retract the pair of eyelids, and fixes the arms into place to maintain retraction of the pair of eyelids. The air-flow system is coupled to at least one arm, and moves air in a region disposed outwardly from a surface of the eye.

    Abstract: In certain embodiments, a patient interface for an ophthalmic laser system comprises an interface portion and an attachment portion. The interface portion comprises a contact portion, a cone wall, and one or more structures. The contact portion has an abutment face that is configured to be in contact with the cornea of an eye. The cone wall is disposed outwardly from the contact portion and defines a cone interior. The cone wall has an inner surface and an outer surface, where the inner surface defines the cone interior. The cone wall has an upper portion and a lower portion, where the lower portion is coupled to the contact portion. The one or more structures direct light from the cone wall towards the cone interior. The attachment portion affixes the interface portion to the cornea of the eye.

    Abstract: In certain embodiments, an ophthalmic surgical system for performing a surgical procedure on an eye comprises a laser device, a camera, and a computer. The laser device comprises a laser source and a scanner. The laser source generates a laser beam comprising pulses, and the scanner directs the pulses towards tissue of the eye according to a laser focal spot pattern. The camera captures surgical images of the eye. The computer instructs the laser device to direct the pulses towards the eye according to the laser focal spot pattern, accesses and monitor the surgical images of the eye, identifies an interfering object from the surgical images of the eye, and modifies the control of the pulses to compensate for the interfering object.

    Abstract: According to certain embodiments, an ophthalmic system for providing an image of an eye includes a camera system and a computer. The camera system includes stereoscopic cameras that provide image data for images of the eye. The computer: receives the image data from the camera system; accesses overlay data for an overlay for the image of the eye; aligns the overlay data and the image data; digitally combines the overlay data and the image data to yield combined image data for an image with the overlay; and provides the combined image data to a display device to display the image with the overlay in three dimensions.
