ABSTRACT:
An intraocular light probe has a slit-shaped mask or cannula affixed at a distal end thereof which forms a slit-shaped light beam for intraocular slit-illumination of target features within the eye. A hood at a distal tip portion directs light in a particular direction. A distal flange retains the instrument within the eye. In a second embodiment, a light probe for intraocular application of a slit-shaped light beam is created by forming a slit shape at a distal end of an optical fiber bundle. A third embodiment provides a surgical instrument, such as a phacoemulsifier or vitrector, having an infusion sleeve which incorporates a slit illuminator for intraocular application of a slit-shaped light beam to target tissues. The device of the invention is preferably introduced into the eye via the primary or side-port incision to provide intraocular cross-lighting of tissues during surgical procedures such as cataract extraction, vitrectomy, intraocular lens implantation, refractive surgery, and glaucoma surgery.
