A retinal imager for imaging a retina of an eye includes an illumination source operable to generate illumination light and a beam splitter operable to receive the illumination light and direct the illumination light along an optical axis. The retinal imager also includes a field lens disposed along the optical axis and an objective lens disposed along the optical axis and operable to contact a cornea of the eye. An aerial image is formed adjacent to the field lens. The retinal imager further includes an image sensor and one or more lenses disposed along the optical axis between the beam splitter and the image sensor. The one or more lenses are operable to form a sensor image at the image sensor.

A novel surgical lens system including a lens and a reflective element. The lens is placed on, or above, a cornea of an eye of a subject for enabling inspection of the eye. The reflective element is incorporated into the lens. The reflective element reflects a light beam toward the eye of the subject. The reflective element increases the divergence of the light beam, such that the divergence of the reflected light beam is larger than the divergence of the light beam. The light beam is emitted by a non-invasive light source positioned externally to the eye.

A contact lens is placed on a patient's eye during ophthalmic surgery, such as vitreoretinal surgery. The contact lens rests on a cornea of an eye of a patient during the surgery and is supported by a contact lens mounting speculum having multiple degrees of freedom to accommodate small movements of the eye while enabling alignment to an optical axis of the surgical microscope. The contact lens mounting speculum may be used with different patients, speculum blades, contact lenses (direct and indirect), and lens mounting positions.

Compositions comprising one or more chelating agents and optionally zinc ion salts are used to inhibit the growth or biofilm formation in bacteria associated with personal care products such as ophthalmic, pedicure, manicure or podiatric solutions. The compositions of the present application can also comprise gelling agents, antimicrobials, antibiotic or a pH adjuster. The compositions may be in the form of a solution, a gel, a cream, a jelly, a powder, a paste, a lotion, soap and a cleaner.

A therapeutic methodology for improving eye contact in children with ASD. A plurality of pairs of contact lenses is provided to an adult, typically a therapist or a parent of a child, where the contact lenses have an image of a subject of interest to the child imprinted on the contact lens. The plurality of the pairs of contact lenses provides a series of pairs of contact lenses where the image is gradually faded. An adult interacting with the child begins by wearing contact lenses having an image of greatest intensity. Through a series of therapy sessions with the therapist uses the contact lenses, as the child's duration and frequency of eye contact improves, the therapist will then use lenses with the image of the subject of interest to the child that are gradually faded. When therapeutic goal of the targeted duration and frequency of eye contact is reached, therapy using the contact lenses can be terminated.

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.
