Mechanical optics for mode mixing may be used to homogenize different modes in an optical fiber used for surgical illumination. A mechanical optical element, such as a rotating prism or a mirror membrane, may impart motion to an incident beam entering the optical fiber to generate a homogeneous illumination field from a coherent light source.

Pixelated array optics for mode mixing may be used to homogenize different modes in an optical fiber used for surgical illumination. A pixelated phase array, such as a digital micromirror device or an LCD phase plate, may impart motion to an incident beam entering the optical fiber to generate a homogeneous illumination field from a coherent light source.

An exemplary illumination system is provided herein for use in performing an ophthalmic surgical procedure. The illumination system may include a body configured to be held by a hand of a user. The body may include an outer surface and an inner surface that defines an inner chamber. The exemplary illumination system may further include an elongate tubular member extending from a distal end of the body, which may have an illumination path within a lumen of the elongate tubular member, and an illumination source coupled to the illumination path through an optical fiber extending between the body and a surgical console. The exemplary illumination system may include a plurality of illumination controls disposed on the outer surface of the body. A first illumination control may permit the user to selectively control an adjustable illumination level between a high intensity state and a low intensity state.

A dispensing assembly has a dispensing chamber housing, a temperature control device, a thermal sensor, and an interface. The dispensing chamber housing has an inner surface, an outer surface, and a wall thickness. The inner surface partially defines a dispensing chamber for receiving a quantity of a substance. The temperature control device at least partially surrounds the dispensing chamber housing. The temperature control device alters a temperature of a substance in the dispensing chamber. The temperature control device and the thermal sensor are located on a substrate. The substrate is wrapped around an exterior surface of the dispensing chamber housing. The interface is connected to the temperature control device and the thermal sensor. An interface connector is connected to the interface. The distance between the temperature control device and the thermal sensor is approximately equal to the wall thickness of the dispensing chamber housing.

A MEMS check valve includes a supporting portion having a first perforation therethrough sized to permit fluid flow and includes a displaceable portion having a second perforation therethrough sized to permit fluid flow. The displaceable portion may be moveable relative to the supporting portion between a closed position inhibiting fluid flow through the valve and an open position permitting fluid flow through the valve. The first and second perforations are offset to inhibit fluid flow when the displaceable portion is in the first position, and fluid may flow through the first and second perforations when the displaceable portion is in the second position.
