Fragmentation Handpiece

The Fragmentation handpiece is conﬁgured to provide simultaneous vacuum and

fragmentation, or vacuum only, depending upon the console setup. The handpiece has

a stainless steel shell for improved reliability and durability. Other than attaching and

removing the needle and aspiration line, no assembly or disassembly is required.

Figure 2-75 Fragmentation Handpiece

Phaco Ultrasound Handpieces

Alcon's phaco handpieces integrate irrigation, aspiration and emulsiﬁcation. The three

functions of the lens extraction step enable the surgeon to simultaneously maintain or

inﬂate the anterior chamber, emulsify the lens, and aspirate the lens material from the

eye.

These handpieces require no disassembly other than removal of the disposable tubing,

the ultrasonic tip, and the infusion sleeve with bubble suppression insert.

CAUTIONS

Do not test or operate

U/S handpieces unless the tip is immersed in BSS

sterile

irrigating solution or distilled water or is in surgical use. Irreparable damage to

the handpiece and tip can result if run dry.

Ensure that test chamber is ﬁlled with

BSS

sterile irrigating solution before tuning

U/S handpieces. Tuning a handpiece dry may result in premature tip failure and

breakage.
