An eye-imaging apparatus and system is described including arrayed optical fibers having a high numerical aperture and circular fiber array ends arranged at skewed angles relative to the optical axis of the imaging path. Circular fiber array ends are arranged to emit the illumination light into an eye at a skewed angle and a light intensity distribution converter along the illumination path to convert a bell-shaped distribution into a top-hat distribution. As a result, illumination uniformity on the retina of the eye is improved.

A contact-type ophthalmoscope includes a contact lens, an annular illumination module, an imaging lens group and an image capture module. The contact lens having a concave surface is configured for contacting an eyeball. The annular illumination module arranged close to the contact lens is configured for providing a direct illumination light source to illuminate a fundus of the eyeball. The imaging lens group is disposed in the central hollow portion of the annular illumination module and configured for converging the reflected light from the fundus of the eyeball. The image capture module is configured for capturing the reflected light converged by the imaging lens group to form an image. The above-mentioned contact-type ophthalmoscope has advantages of better illumination efficiency, compactness and less scattered light reflected from the imaging lens.

A contact lens for use with a surgical microscope may be equipped with an anti-fogging device to prevent obscuring the view of a surgeon due to condensation during ophthalmic surgery. The anti-fogging device may deliver thermal energy to a surface of the contact lens to heat the contact lens above an ambient dew point. The thermal energy may be delivered by an air duct with a fan nozzle, a fluid duct in thermodynamic contact with the contact lens circulating a heat transfer fluid, or generated with electrical energy to an electrical heating element disposed on the surface of the contact lens. The thermal or electrical energy may be delivered via a handle for supporting the contact lens during surgery.

A device (1) for eye surgery includes a metallic ring (2) for suturing to the sclera of a patient's eye. A locking element (3) can be coupled to the metallic ring (2). The locking element (3) includes a lens (31) and a coupling ring (32) fixed to the lens (31) along the entire circumference of the inner edge of the lens (31). The coupling ring (32) is configured for coupling to the metallic ring (2).

The present disclosure relates to calibration, customization, and improved user experiences for smart or bionic lenses that are worn by a user. The calibration techniques include detecting and correcting distortion of a display of the bionic lenses, as well as distortion due to characteristics of the lens or eyes of the user. The customization techniques include utilizing the bionic lenses to detect eye characteristics that can be used to improve insertion of the bionic lenses, track health over time, and provide user alerts. The user experiences include interactive environments and animation techniques that are improved via the bionic lenses.
