The present disclosure relates to operations that include identifying a first transition-edge portion of a first image of an eye that corresponds to a transition edge of the eye. The operations may also include determining, based on first-portion pixel data corresponding to the first transition-edge portion, a first transition-edge representation of the transition edge. The operations may include identifying a second transition-edge portion of a second image of the eye that corresponds to the transition edge. In addition, the operations may include determining, based on second-portion pixel data corresponding to the second transition-edge portion, a second transition-edge representation of the transition edge. Moreover, the operations may include determining an alignment registration between the eye as depicted in the first image and the second image based on a transition-edge based registration that is based on a comparison between the first transition-edge representation and the second transition-edge representation.
In certain embodiments, an illumination system for a microscope includes an illumination source and a computer. The illumination source comprises light engines. The computer receives an illumination request comprising a color request and an intensity request. The color request includes color selections, where each color selection requests a color output for at least a subset of the light engines. The intensity request includes intensity selections, where each intensity selection requests an intensity output for at least a subset of the light engines. The computer determines intensity inputs according to the intensity request, where each intensity input provides an illumination instruction to a light engine. The computer determines color inputs according to the color request, where each color input provides a color instruction to a light engine. The computer generates light engine inputs from the intensity inputs and the color inputs and sends the light engine inputs to the light engines.

An ophthalmic lens may comprise a posterior optic surface and an anterior optic surface, which may comprise a central optic, a peripheral optic, and a capsule rim separating the central optic and the peripheral optic. An optic edge may couple the posterior optic surface to the peripheral optic. The capsule rim may be symmetric or asymmetric in various embodiments. In more particular embodiments, the capsule rim may form a surface at an angle of at least ninety (90) degrees to the peripheral optic. In some embodiments, the central optic may comprise an optic axis, and the capsule rim may form a surface that is substantially parallel to the optic axis.
Devices and methods are provided for delivering gas. In one example, the device includes a syringe body including a proximal end, a distal end including an outlet and a gas chamber communicating with the outlet, and a plunger carrying a piston slidably received within the syringe body. A canister containing a gas is provided within the plunger adjacent a passage through the piston communicating with the gas chamber. A drive actuator is movable to cause an opener pin to open a septum of the canister and release the gas, whereupon the gas travels through the passage into the gas chamber, thereby displacing the piston proximally to fill the gas chamber. Once activated, the plunger may be advanced to deliver the gas within the gas chamber through the outlet into a patient's body, e.g., into an eye via a cannula connected to the outlet.
Embodiments of the present disclosure relate to improved surgical laser systems with single-core single-optical fiber-illuminated laser probes, which are configured to propagate both treatment laser beams and illumination light beams. More particularly, embodiments of the present disclosure provide surgical laser systems with color adjustability of illumination light, as well as improved laser probe stiffness.
