    Abstract: The present disclosure provides a system for femtosecond ophthalmic surgery in which the position of a suction cone in the z direction is measured via the measuring device to generate data that is processed and used to create a pictorial representation, a histogram, or other graph based on the data. The pictorial representation may include at least one threshold marker. The disclosure further provides a method of performing docking in femtosecond laser ophthalmic surgery including measuring the position of a suction cone with a measuring device, and transmitting data regarding the position to a processor which processes the data and uses it to create a pictorial representation, histogram, or other graph that is presented on a display.

    Abstract: The present disclosure provides a system for femtosecond ophthalmic surgery in which a measuring device and a camera generate data that is processed and used to create an enhanced pictorial representation based on the actual positions of the suction ring and the eye. The pictorial representation may include a graphic relating to ophthalmic surgery, such as for a flap or an incision. The disclosure further provides a method for docking a suction ring in femtosecond laser ophthalmic surgery, which includes observing and generating data relating to the position of the suction ring, generating data relating to a pictorial representation of the suction ring and the eye, processing the data relating to the observed position and the pictorial representation to generate an enhanced pictorial representation, and presenting it during surgery. The pictorial representation may include a graphic relating to ophthalmic surgery, such as for a flap or an incision.

    Abstract: The disclosure provides a system that may provide a virtual object at a first virtual distance to an eye of a patient; may provide a first light wave to the eye; may receive a first perturbed light wave, based at least on the first light wave, from the eye; may determine first optical corrections based at least on the first perturbed light; may provide the virtual object at a second virtual distance to the eye; after providing the virtual object at the second virtual distance, may provide a second light wave to the eye; may receive a second perturbed light wave, based at least on the second light wave, from the eye; may determine second optical corrections based at least on the second perturbed light; and may determine a corrective optical solution for the eye based at least on the first optical corrections and the second optical corrections.

    Abstract: In certain embodiments, a system for making an implant for an eye comprises a printer, a camera, and a computer. The printer prints material onto a target and has a printer head and printer controller. The printer head deposits the material onto the target, and the printer controller moves the printer head to deposit the material onto a specific location of the target. The camera generates an image to monitor the printing of the material. The computer stores a pattern for the implant, which is designed to provide refractive treatment for the eye; sends instructions to the printer controller to move the printer head to print the material onto the target according to the pattern; assesses the image from the camera according to the pattern; and adjusts the instructions in response to the image.

    Abstract: An ophthalmic laser surgical system for treating an eye includes a laser device, one or more cameras, and a computer. The eye has anatomical features, including the cornea with the anterior corneal surface. The laser device directs a laser beam towards the eye. A camera generates images of the anatomical features, including the anterior corneal surface. The computer facilitates docking a patient interface onto the eye by accessing eye information describing the eye. The eye information comprises an eye model describing the anatomical features. The computer determines from the eye model the predicted corneal surface position when the eye is aligned to dock the patient interface onto the eye. The computer detects from the images the actual corneal surface position prior to docking the patient interface onto the eye, and compares the predicted corneal surface position with the actual corneal surface position to detect misalignment.

    Abstract: In certain embodiments, a system for making an implant for an eye comprises a laser, a camera, and a computer. The laser emits a laser beam to shape a material. The camera generates one or more images to monitor shaping of the material. The computer stores a pattern for the implant, which is designed to provide refractive treatment for the eye; sends instructions to the laser to control the laser beam to shape the material according to the pattern; assesses the images from the camera according to the pattern; and adjusts the instructions in response to the images.
