A Bernoulli gripper for ophthalmic lenses includes a gripper body with a first cavity corresponding in shape to an optic zone of an ophthalmic lens and a first channel formed within the gripper body. The first channel penetrates the first cavity at one end and includes a first port in the gripper body at another end of the first channel. The first channel is enabled to supply a fluid medium from the first port to the first cavity at a first velocity such that the ophthalmic lens positioned with the optic zone in proximity to the first cavity is subject to a first pressure force against the first cavity by the Bernoulli effect.

A lens manipulator that includes an over-sleeve with a suction cup and lumen therethrough that forms a pore in the suction cup and a rod opening at the opposite end for receiving an adjustment rod. Adjustment of the length of the adjustment rod in the lumen controls the amount of suction force generated under the suction cup against a contact lens. Removal of the adjustment rod from the lumen eliminates the suction force and acts as a safety release against excessive pull force on an eye when removing a contact lens.

The present invention features devices, systems, and methods of use thereof for delivering therapeutic or sterilizing ultraviolet (UV) radiation, such as UVC or UVA radiation.

A method for centring a contact glass relative to a patient's eye includes a) providing a fixation light through a contact glass to align the patient's eye glass fixing on the fixation light; b) detecting an image of a light pattern that is imaged on the eye's surface; c) presenting the image over the eye with the contact glass with overlaying of virtual markings, wherein a first marking identifies the central axis of the contact glass and a second marking identifies a reference marking, which is derived from the image of the light pattern as lying on the central axis of the contact glass; d) laterally positioning the contact glass such that a distance between the markings is minimized; and e) establishing the position of the eye at which the second marking is located when the markings adopt the minimized distance and registering the position of the vertex.

A contact lens applicator for applying a contact lens to an eye of a user includes a base member, a stand, and a lens holder. The stand includes a first end, a second end, and a passageway. The lens holder includes a handle, a cup, and a passageway. The first end of the stand removably engages with the lens holder. The second end of the stand removably engages with the base member. The cup of the lens holder is configured to hold a contact lens. When the lens holder and the stand are removably engaged with the base member, the passageway of the stand and the passageway of the lens holder align above the base member, allowing natural light to pass through the passageways of the stand and the lens holder.

The problem of inserting and removing a rigid gas permeable or hybrid contact lens is solved by the use of a lens manipulator. The lens manipulator includes a handle and an over-sleeve that is optionally attachable to an extraction stem, for creating a suction force to remove a contact lens, and an insertion stem, without suction force for placing a contact lens. Removal of the extraction stem from the over-sleeve eliminates the suction force and acts as a safety release against excessive pull force on an eye when removing a contact lens. A manual-release mechanism can be used to facilitate removal of the extraction stem.

A contact lens applicator is described which automatically applies a contact lens to a user's, or a patients, eye. Embodiments described include a contact lens applicator which includes: a main tool base for housing control system elements; a robotic arm mounted on the tool base; an end effector mounted on an end of the robotic arm for grasping a contact lens for delivery to an eye of the user.

A contact lens applicator for applying a contact lens to an eye of a user includes a base member, a stand, and a lens holder. The base member includes an inner surface and retaining walls. The stand includes a first end, a second end, at least one leg, and a passageway. The lens holder includes a handle, a cup, and a passageway. The first end of the stand removably engages with the handle of the lens holder. The second end of the stand removably engages with the base member. The cup of the lens holder is configured to hold a contact lens. When the lens holder and the stand are removably engaged with the base member, the passageway of the stand and the passageway of the lens holder align above the base member, allowing natural light to pass through the passageways of the stand and the lens holder.
