Abstract: A phacoemulsification probe for use with eye surgery comprises a probe tip defining a channel there in the probe tip defining an opening having a first diameter for aspirating material from a surgical area long a first vector. The probe tip further defining a channel therein the channel having a second diameter greater than the first diameter of the opening. A flexible sleeve surrounding a body of the probe tip. A first end of the flexible sleeve forming a seal between the probe tip and the flexible sleeve. A remainder of the flexible sleeve defines a second channel between the body of the probe tip and the flexible sleeve. The flexible sleeve further defines an opening for injecting a fluid from the second channel into the surgical area along a second vector.

Abstract: A phacoemulsification probe for use with eye surgery comprises a connector for interconnecting the probe with a phacoemulsification machine. A probe tip has a first end with a first central axis running therethrough connected with the connector and a second end with a second axis running therethrough. The second axis is at a predetermined angle to the first central axis. The probe tip further includes a body defining a channel therein for aspirating material from a surgical region within an eye through an opening in the second end along a first vector. The body includes a straight portion around the central axis connected to the first end and a curved portion connecting the straight portion to the second end. A fluid sleeve surrounds at least a portion of the probe tip and has a first end and a second end. The fluid sleeve has a first portion at the first end having a first diameter that prevents a fluid from flowing between the fluid sleeve and the body of the probe tip.

Abstract: An aspiration probe tip for use in surgical procedures includes a body defining a first channel therein for aspirating material therethrough from a surgical region along a first vector. The body includes a straight portion connected to a first end and a curved portion connecting the straight portion to a second end. A fluid sleeve surrounds at least a portion of the body and defines a second channel between the fluid sleeve and the body for injecting a fluid into the surgical region along a second vector. An end of the fluid sleeve securely fits over the body to substantially seal the end of the fluid sleeve. The fluid sleeve further defines an aperture for injecting fluid along the second vector from the second channel into the surgical region.

The fluid sleeve further defines an aperture for injecting fluid along the second vector from the second channel into the surgical region. A combination of the aspiration of the material into the first channel from the surgical region along the first vector and injection of fluid into the surgical region from the second channel creates a cyclonic movement within the surgical region.

Abstract: A cover and packaging and method for use in preventing infection in applanation tonometry eye testing. The cover has a circular transparent portion, a frustum shaped mounting portion and a frustum shaped handling flange. It is sterile, disposable, unitarily dispensable, and fits onto existing standard applanation tips. The circular transparent portion of the cover has an effective amount of a photoactive agent therein for enhancing the view of the calibration image during the pressure measurement.

Abstract: A knife for ophthalmic surgery and particularly for posterior capsulotomy procedures comprises a thin, continuously curved shaft having an elongated handle attached at one end thereof. The longitudinal axis of the handle is disposed substantially tangentially to the curved shaft. A blade portion on the opposite end of the shaft terminates in a sharp tip. The shaft tapers from a relatively thick section adjacent the handle to a relatively thin section adjacent the blade portion.

Abstract: An intraocular lens is provided for implantation into the posterior chamber of the eye following extracapsular cataract surgery. The lens body includes a convex posterior surface having an optic area positioned in direct apposition to the posterior capsular membrance. The curvature of the posterior surface of the lens is fixed and power modifications are made by changing the curvature anterior optical surface of the lens body. The circumferential edge of the lens body is angled posteriorly to provide an annular space outside the optic area of the lens for laser or knife surgery frequently necessary after the lens implantation by extra capsular technique.

Abstract: An irrigation and aspiration syringe is provided for one-handed operation. A cylindrical syringe barrel has a first axial control grip projecting from the nozzle end of the syringe. An outer tubular member surrounds the syringe barrel and is connected to the rod of a plunger fitted within the syringe cartridge. A second axial control grip is affixed to the outer tubular member. Aspiration is effected by oppositely directed axial forces applied to the first and second control grips with the thumb and forefinger of one hand.
