To make it possible to improve user convenience, provided is a control device including: a control unit configured to control a position and an attitude of a microscope unit by driving an arm unit that supports the microscope unit on the basis of a captured image of an operating site photographed by the microscope unit during an operation so that a position and attitude condition set before the operation is satisfied. The position and attitude condition is a condition that prescribes a position and an attitude of the microscope unit with respect to the operating site to obtain a desired captured image corresponding to the position and attitude condition.

An eyelid retractor and irrigation tool includes a handle portion defining a longitudinal first axis configured to be grasped by a user and a hook portion connected to the handle portion for retracting an eyelid. The hook portion of the tool includes: inwardly and outwardly facing walls, which are curved about a second axis, which is distinct from the first axis; an edge wall extending between the inwardly and outwardly facing walls; and an interior cavity defined by the walls. The tool further comprises at least one opening extending through the inwardly facing wall or the outwardly facing wall fluidly connected to the interior cavity and positioned such that fluid in the interior cavity passes through the at least one opening to irrigate portions of an eye including the eyelid.

Techniques for fabrication of implant material for the reconstruction of fractured eye orbit may include using an image processing system to analyze a set of two-dimensional images representing a three-dimensional scan of a skull of a patient, automatically detect an orbital fracture in the skull based on the set of two-dimensional images, and identify which/both of the two eye orbits containing any orbital fracture. The techniques may further include, for each of the two-dimensional images in which the orbital fracture is detected, determining a region of interest, and extracting the region of interest. The techniques may further include generating a three-dimensional reconstruction model for the fractured eye orbit, and outputting model data for generating an implant mold for the fractured eye orbit.

An ocular fixation device includes a body configured to be placed on an eye. The ocular fixation device also includes multiple twist picks configured to be turned to secure the body to the eye and to release the body from the eye. The body includes connection points on which a surgical tool is mountable on the body.

An ophthalmic device for fundus examination comprising at least one light-permeable end, designed to come in contact with the eye and provided with a light source that allows illumination of the eye fundus cavity through the eyeball without the need of an external light source that may cause reflections or artifacts displayed on lenses or magnifying glasses used by professionals during the examination.

The position and attitude condition is a condition that prescribes a position and an attitude of the microscope unit with respect to the operating site to obtain a desired captured image corresponding to the position and attitude condition.

An expander for widening and holding apart an opening of a tissue. The expander may include a body configured to deform from a compacted state into a pre-determined shape in an expanded state in response to a pre-determined physiological condition the body is exposed to. The body with the pre-determined shape in the expanded state may be configured to hold apart the opening of the tissue.

Surgical instrument subcomponent integration by additive manufacturing may include identifying at least two subcomponents of a multi-component assembly wherein a first subcomponent of the at least two subcomponents has a first functionality and wherein the first subcomponent of the at least two subcomponents is manufactured from a first material having a first set of material properties. Surgical instrument subcomponent integration by additive manufacturing may include modifying one or more properties of the first subcomponent of the at least two subcomponents to reproduce the first functionality when the first subcomponent is manufactured from a second material having a second set of material properties. Surgical instrument subcomponent integration by additive manufacturing may comprise integrating the at least two subcomponents by manufacturing an integral component by additive manufacturing wherein the integral component is manufactured from the second material and wherein the first functionality is retained.

Fiber-based mode mixing techniques may be used to homogenize different modes in an optical fiber used for surgical illumination. A vibrating fiber mechanism may impart mechanical motion to a portion of the optical fiber to generate a homogeneous illumination field from a coherent light source.

Systems, devices and methods for dilating and/or expanding the iris of a patient's eye during eye surgery is disclosed, comprising an elastomeric ring made from biocompatible material having a groove formed therein for receiving and protecting the pupillary rim and iris, whereby, when the ring is inserted into the pupil of an eye of a patient, it mechanically dilates the pupil.
