Family of Tips
U/S tips are made of medical grade titanium alloy, and are attached to an U/S
handpiece to deliver mechanical energy to the lens, assisting in its removal by
aspiration. Depending on the needs and technique preferred by the surgeon, various
styles of tips and tip bevels are available (see Figure 2-77). Various U/S tip styles are
color coded.
• 1.1 mm U/S Tips - The standard ultrasonic tips are the original 1.1 mm
TurboSonics
®
tips. They are designed for use only with 1.1 mm infusion sleeves.
• 0.9 mm U/S Tips - The 0.9 mm ultrasonic tips are designed to allow entry through
a smaller incision. They are designed for use only with 0.9 mm infusion sleeves.
• Aspiration Bypass System - Tips with the ABS
®
feature contain a small hole in
the distal portion of the tip’s wall. This helps to maintain flow through the system
even during occlusion of the tip’s main port.
WARNINGS!
Use 0.9 mm tips with 0.9 mm infusion sleeves. Use 1.1 mm tips with 1.1 mm
infusion sleeves. Mismatch of consumable components and use of settings not
specially adjusted for a particular combination of consumable components may
create a patient hazard.
Read all package label material printed on the consumable paks prior to their use.
Standard U/S Tips - The 1.1 mm TurboSonics
®
tip
with the round shaft is the original, classical U/S
tip shape. The 0.9 mm has a smaller diameter shaft.
The Aspiration Bypass System - Tips with
the ABS
®
feature contain a small hole in the distal
portion of the tip's wall.
Kelman
®
Tips - The Kelman
®
tips have a bent shaft
which generates transverse ultrasound motion, in addition
to the conventional longitudinal motion, to enhance cutting
efficiency. In addition, the bend allows better visibility
during the surgical procedure.
Tapered Tip - The tapered ABS
®
tip is a combination
of the 0.9 mm tip and the flared ABS
®
tip. The shaft
inner and outer diameters is equivalent to straight tips,
while the distal end is comparable to flared tips. The
tapered ABS
®
tip has the improved holding force of a
flared tip, and the same aspiration flow characteristics
as a straight tip.

Flared ABS
®
Tips - The flared tips have a larger proximal
port, providing increased holding force. They narrow in the
middle of the shaft, thus allowing smaller incisions and
improving occlusion breaks by reducing outflow from the
anterior chamber, following occlusion breaks. Flared tips
also have the Aspiration Bypass System feature, to further
enhance performance.
