A sleeve for use during an ophthalmic procedure, comprising:
- a body portion having a proximal end and a distal end, the proximal end of the body portion is configured to receive a phacoemulsification sleeve covering a phacoemulsification needle attached to a handpiece, said sleeve adapted to fully enclose the phacoemulsification needle to transform the handpiece from a phacoemulsification handpiece to an irrigation and aspiration handpiece, and the proximal end of the body portion is configured to connect to at least one of the handpiece and the phacoemulsification sleeve at a sleeve attachment;
- and
- a tip portion having at least one linear portion configured to receive a linear portion of the phacoemulsification sleeve and phacoemulsification needle and a curved distal end portion comprising at least one aspiration port and a rounded end portion at a distal most tip of the curved distal end portion extending beyond the phacoemulsification needle and suitable for use around an edge of a capsular bag of an eye.
A phacoemulsification system for use during an ophthalmic procedure, comprising:
- a handpiece;
- a phacoemulsification sleeve covering a phacoemulsification needle, the phacoemulsification needle configured to connect to the handpiece;
- and
- a sleeve that transforms the handpiece from a phacoemulsification handpiece to an irrigation and aspiration handpiece, the sleeve including a body portion and a tip portion,
- the body portion having a proximal end and a distal end, the proximal end of the body portion is configured to receive the phacoemulsification sleeve covering the phacoemulsification needle and is configured to connect to at least one of the handpiece and the phacoemulsification sleeve at a sleeve attachment, and
- the tip portion having at least one linear portion configured to receive a linear portion of the phacoemulsification sleeve and phacoemulsification needle and a curved distal end portion comprising at least one aspiration port and a rounded end portion at a distal most tip of the curved distal end portion extending beyond the phacoemulsification needle and suitable for use around an edge of a capsular bag of an eye.
