A vitrector that includes an adjustable illumination aperture is described. The vitrector may include a probe and a light sleeve assembly extending along and substantially surrounding the probe. The light sleeve assembly may include a plurality of optical fibers. At least a portion of the optical fibers are operable to provide illumination so as to define an illumination aperture about the vitrectomy probe. A portion of the optical fibers may be encapsulated. The light sleeve assembly may be adjustable along a length of the probe, providing adjustment of the illumination aperture to increase or decrease an area of illumination provided thereby.

Systems, processes, and computer program products may be used to perform retinal surgery. In particular implementations, a system, a process, and a computer program product may include the ability to inject a retina manipulation fluid into an eye through an injection/extraction system and apply negative pressure to the injection/extraction system to facilitate extraction of fluid from the eye. The system, the process, and the computer program product may also include the ability to adjust the applied negative pressure.

Retinal surgery

An extraction sleeve assembly for use in extracting a viscous fluid from the posterior segment of an eye during vitreoretinal surgery is disclosed. The extraction sleeve assembly includes a luer lock fitting and a flexible, tubular extraction sleeve. The extraction sleeve assembly facilitates a shorter extraction time for the viscous fluid.
