A system (100) includes a long cannula (101), an optical fiber (108), and a multi-spot generator (102). The optical fiber (108) can carry a laser beam to a distal end of the long cannula (101). The multi-spot generator (102) is located within a short cannula (103) at the distal end. The short cannula (103) is disposed within the long cannula (101). The multi-spot generator (103) comprises a faceted optical element (104) and a ball lens (106). The faceted optical element (104) can be formed directly onto or separately from the ball lens (106). The ball lens (106) can be spherical or hemispherical. The ball lens (106) is press-fit in the short cannula (103).

An intraocular lens inserter can include a drive device with controllable advance motion. The drive device may include an actuator device and an energy device. The actuator device may include a piston rod that uses the advance motion to push an intraocular lens from a cartridge for insertion into an eye of an animal The energy device may act upon the actuator device to generate the advance motion. The actuator device may include a dampening medium to control the advance motion, such as by controllably dampening the advance motion.

An intraocular lens inserter can include an energy storage portion, an actuator portion that provides temperature compensation, and a lens support portion. The energy storage portion can include a compressible energy storage device, such as a compressible fluid, springs, and other devices. The inserter can include an actuator portion operating with a substantially incompressible fluid. The actuator can be configured to provide an operator with control over the release of pressurized fluid so as to move a plunger for the discharge of a lens from an intraocular lens cartridge, discharge of the lens being limited based at least in part on pressure feedback from the pressurized fluid due temperature increases.

In one exemplary aspect, the present disclosure is directed to a system. The system includes a pneumatic surgical instrument and a surgical console operable to provide compressed gas to the pneumatic surgical instrument. Additionally, the system includes a pneumatic drive line coupling the pneumatic surgical instrument to the surgical console. The pneumatic drive line has an internal bore configured to deliver the compressed gas to the pneumatic surgical instrument. The internal bore has a non-uniform cross-section along a length of the pneumatic drive line.

The use of poly(oxyethylene)-poly(oxybutylene) block copolymers in pharmaceutical compositions useful for modifying the surfaces of contact lenses and other medical devices is disclosed. The present invention is based in-part on a discovery that this class of compounds is particularly efficient in wetting hydrophobic surfaces, such as the surfaces of silicone hydrogel contact lenses and other types of ophthalmic lenses. Such compounds are also useful for cleaning purposes. The use of the compounds as surfactants in various types of compositions for treating contact lenses therefore represents a preferred embodiment of the present invention.

An optical surgical probe includes a handpiece, a light guide within the handpiece, and a multi-spot generator at a distal end of the handpiece. The handpiece is configured to optically couple to a light source. The light guide is configured to carry a light beam from the light source to a distal end of the handpiece. The multi-spot generator includes a faceted optical element with a faceted end surface spaced from a distal end of the light guide. The faceted end surface includes at least one facet oblique to a path of the light beam.
