Description

[Technical Field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates to ophthalmic surgery and surgical equipment, and more particularly to systems and methods associated with utilizing one or more images of an eye in a medical procedure. [Background technology]

[0002] Eye surgery protects and improves the vision of tens of thousands of patients each year. However, due to the sensitivity of vision to even slight changes in the eye and the delicate and delicate characteristics of many ocular structures, eye surgery is difficult to perform, and even reducing minor or rare surgical errors or improving surgical skill precision can make a noticeable difference in a patient's vision after surgery.

[0003] Ophthalmic surgery is surgery performed on the eye or any part of the eye. Eye surgery is typically performed to repair retinal defects, repair eye muscles, remove cataracts or cancer, or maintain or improve vision. For example, refractive eye surgery is a type of eye surgery used to improve the refractive status of the eye with the goal of reducing or eliminating dependence on glasses or contact lenses. Refractive surgery procedures may include surgical remodeling of the cornea and / or cataract surgery, both of which may be performed with one or more lasers.

[0004] In various ophthalmic surgical procedures, lasers can make incisions using photodisruption. When performing eye surgery using a laser, the surgical procedure typically includes docking, imaging, analysis, and laser treatment. During docking, the patient's eye is docked with a suction cone to apply pressure to flatten the patient's cornea (known as applanation) and hold it in place for laser treatment. Docking is a sensitive process, and proper positioning of the suction ring in the Z direction as well as the X and Y directions is critical to the success of the eye surgery. Summary of the Invention [Means for solving the problem]

[0005] The present disclosure provides a system capable of acquiring an image of at least an eye of a person via at least one image sensor. In one example, the at least one image sensor may include at least one camera. In a second example, the at least one image sensor may include multiple image sensors. In another example, the at least one image of the eye may include multiple images of the eye. The system may further determine a position of an iris of the eye from at least the image of the eye, and may further determine a position of a suction ring from at least the image of the eye. For example, the system may determine a position of a suction ring from at least the image of the eye before docking the suction ring with the eye. The suction ring may be docked with the eye for a medical procedure. The system may further display at least the image of the eye via a display. For example, the display may be integrated with a microscope. The system may include a display integrated with the microscope. The system may further display a first graphic overlay on at least the image of the eye via the display indicating a position of the iris of the eye, and may further display a second graphic overlay on at least the image of the eye via the display indicating a position of the suction ring. For example, the second graphic overlay can guide the physician or surgeon in docking the suction ring with the eye. The system can further determine a plurality of iris structures from at least the image of the eye. In one example, the plurality of iris structures can be one or more bases for which the eye points in one or more directions. In another example, the plurality of iris structures can be one or more bases for which the eye has one or more measurements. The system can further determine an orientation of the eye based on at least the plurality of iris structures from at least the image of the eye, and can further display information indicative of the orientation of the eye via the display. For example, the information indicative of the orientation of the eye can include a graphic overlay depicting a reticle associated with the orientation of the eye.

[0006] The system may further display, via the display, a graphic overlay representing a reticle associated with the orientation of the suction ring. For example, the reticle associated with the orientation of the suction ring may guide a physician or surgeon in docking the suction ring with the eye. The system may further determine at least one incision site based on at least a plurality of iris structures from at least the image of the eye, and may further display, via the display, a graphic overlay indicating the at least one incision site. Determining the at least one incision site may include determining a plurality of incision sites. The system may further display, via the display, a plurality of graphic overlays indicating respective ones of the plurality of incision sites. For example, the system may simultaneously display, via the display, a plurality of graphic overlays indicating respective ones of the plurality of incision sites. The system may further determine an angular measurement from an iris structure of the plurality of iris structures relative to the center of the pupil of the eye. For example, the system may display, via the display, a graphic overlay indicating the at least one incision site based at least on the angular measurement.

[0012] In the following description, details are provided as examples to facilitate discussion of the disclosed subject matter, but it should be apparent to those skilled in the art that the disclosed embodiments are examples only and do not encompass all possible embodiments.

[0013] As used herein, reference numbers designate a class or type of object, and letters appended to such reference numbers designate a particular instance of a particular object of that class or type. Thus, for example, a hypothetical object referenced by "12A" designates a particular instance of a particular class / type, and the reference "12" may designate a population of instances belonging to a particular class / type or any one instance of that class / type generally.

[0014] At the start of a medical procedure (e.g., an eye surgery procedure), a patient may be placed on a support platform facing up. For example, the support platform may be or may include, among other things, a couch, a table, or a bed. Prior to the medical procedure, one or more components of a docking device may be docked with the patient's eye. For example, the one or more components of the docking device may include, among other things, one or more of a suction ring, a suction cone, and a lens. The laser eye surgery system may include, among other things, a suction cone and a lens. For example, the laser eye surgery system may include a femtosecond laser, and the laser may include, among other things, a suction cone and a lens.

[0015] The surgeon can manually align the suction ring with the eye. For example, the surgeon can place the suction ring on the eye without assistance from a guidance system. If the suction ring is placed incorrectly, the eye may be tilted. For example, if the eye is tilted, the center of the suction ring is offset from the optical axis of the eye, and the medical procedure (e.g., surgical procedure) may not be fully effective. If the medical procedure involves one or more refractive incisions, a tilted eye may prevent the medical procedure from being fully effective.

[0016] A physician can use a guidance system to position the suction ring on the eye. For example, the guidance system can assist the physician in positioning the suction ring on the eye so that the suction ring is aligned or approximately aligned with the optical axis of the eye. The optical axis of the eye can be related to the center of the pupil of the eye. For example, using a guidance system to position the suction ring on the eye can provide one or more advantages, which can include, among other things, guiding the physician in positioning the suction ring in alignment or approximately aligned with the optical axis of the eye and in positioning the suction ring in rotational alignment or approximately rotational alignment with the eye.

[0017] The patient's eye may not be stationary. For example, the patient's eye may move during the docking process. The patient's eye may move left and / or right during the docking process, move up and / or down during the docking process, and / or rotate clockwise and / or counterclockwise during the docking process. The guidance system may determine one or more movements of the patient's eye during the docking process. For example, the guidance system may track the patient's eye. Tracking the patient's eye may include determining one or more positions of the patient's eye during and / or after the one or more movements of the patient's eye. For example, the guidance system may display information indicative of one or more positions of the patient's eye during and / or after the one or more movements of the patient's eye. The information indicative of the one or more positions of the patient's eye during and / or after the one or more movements of the patient's eye may assist and / or guide the physician in docking the suction ring to the patient's eye. For example, information indicative of the one or more positions of the patient's eye during and / or after the one or more movements of the patient's eye may be displayed over one or more images of the patient's eye. The guidance system can augment one or more images of the patient's eye with information indicative of one or more positions of the patient's eye during and / or after one or more movements of the patient's eye. For example, the guidance system can include one or more structures and / or one or more functions of an augmented reality (AR) system, an AR method, and / or an AR process. As described in more detail below, the medical system can include one or more structures and / or functions of a guidance system. For example, the medical system can assist and / or guide a physician in docking a suction ring with the patient's eye.
