A soft-bodied apparatus and a method for opening an eyelid are provided. The apparatus includes: a head support module, a real-time eyelid positioning module, a robot end-effector real-time positioning module, and an automatic eyelid opening operation module. The automatic eyelid opening operation module includes a robot body and a robot control system. The robot body is provided with a multi-axis rigid body mechanical arm and a soft-bodied end-effector. The robot control system takes the real-time poses of the upper and lower eyelids of the user as a motion target, and takes the real-time shape and the pose of the soft-bodied end-effector as feedback information to control motion of the robot body to automatically open the eyelid.

A device includes a body configured to be placed on an eye and multiple tine assemblies configured to secure the body to and release the body from the eye. The body includes multiple corners and multiple sides. Each corner includes a passage through the corner. Each side connects an adjacent pair of corners. Each tine assembly includes a twist pick configured to be inserted through one of the passages. Bottom surfaces of the sides are raised relative to bottom surfaces of the corners such that the bottom surfaces of the sides are spaced apart from the eye when the bottom surfaces of the corners are resting on the eye. Each of at least one side includes multiple openings configured to allow manipulation of a position of the body and a groove configured to receive a projection from a surgical tool in order to position the surgical tool on the eye.

An intraocular shunt can be placed into the eye in an ab externo approach. A clinician may determine an entry area below a corneal limbus of an eye and a target outflow region. Thereafter, the clinician can insert a hollow shaft into the eye at the entry area toward an anterior chamber of the eye, the shaft carrying an intraocular shunt therein. The clinician can position an inflow end of the shunt within the anterior chamber of the eye and, while maintaining the shunt inflow end in the anterior chamber, can remove the shaft from the eye to release the shunt. Finally, the clinician can repositioning an outflow end of the shunt within the target outflow region and verify placement of the outflow end of the shunt within the target outflow region.

A patient interface for an ophthalmic system can include an attachment portion, configured to attach the patient interface to a distal end of the ophthalmic system; a contact portion, configured to dock the patient interface to an eye; and a contact element, coupled to the contact portion, configured to contact a surface of a cornea of the eye as part of the docking of the patient interface to the eye, and having a central portion with a central radius of curvature Rc and a peripheral portion with a peripheral radius of curvature Rp, wherein Rc is smaller than Rp.

A non-sliding, non-sutured hands-free contact lens assembly for ophthalmic procedures utilizes a number of microstructures strategically placed on the bottom of either the contact lens or the bottom of a contact lens holder ring. After the contact lens, or the contact lens assembled with the contact lens holder ring, is placed on the cornea of the eye and centered, a surgeon applies downward pressure either on the contact lens itself or on the lens holder ring. This secures the lens assembly to the cornea due to increased friction between the microstructures and the tissues of the eye when the microstructures penetrate through the tear film and, optionally, viscous solution film and into the contact with superficial layer of cornea or other parts of the eye, thus temporarily anchoring the contact lens, or lens holder, to the desired surgical site.

The invention provides an eye fixation system that allows accurate positioning, stabilization and safe and efficient manipulation of the eye and surgical instrumentation used during procedures and surgeries of the anterior and posterior segments of the eye.

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.

A laser eye surgery system produces a treatment beam that includes a plurality of laser pulses. An optical coherence tomography (OCT) subsystem produces a source beam used to locate one or more structures of an eye. The OCT subsystem is used to sense the distance between a camera objective on the underside of the laser eye surgery system and the patient's eye. Control electronics compare the sensed distance with a pre-determined target distance, and reposition a movable patient support toward or away the camera objective until the sensed distance is at the pre-determined target distance. A subsequent measurement dependent upon the spacing between the camera objective and the patient's eye is performed, such as determining the astigmatic axis by observing the reflection of a plurality of point source LEDs arranged in concentric rings off the eye.

To improve the precision of ophthalmic surgical procedures by reducing corneal wrinkling, a patient interface for an ophthalmic system can include an attachment portion, configured to attach the patient interface to a distal end of the ophthalmic system; a contact portion, configured to dock the patient interface to an eye; and a contact element, coupled to the contact portion, configured to contact a surface of a cornea of the eye as part of the docking of the patient interface to the eye, and having a central portion with a central radius of curvature Rc and a peripheral portion with a peripheral radius of curvature Rp, wherein Rc is smaller than Rp.

Some embodiments disclosed herein relate to devices and methods for controlling placement of intraocular implants within a patient's eye including but not limited to placement within or near the collector ducts of Schlemm's canal located behind the trabecular meshwork. In some embodiments, a handheld peristaltic rotor device having a compression element can be positioned on a corneal surface of the eye and rotated to create a peristaltic movement of blood in one or more episcleral veins to generate blood reflux within Schlemm's canal such that one or more collector ducts, or channels, of Schlemm's canal can be located. In some embodiments, an implant can be implanted near the identified location of the one or more collector ducts, or channels.
