Evaluation of the efficacy and of the safety of the new Stellaris Evaluation of the efficacy and of the safety of the new B&L STELLARIS phacoemulsification system in biaxial and standard phacoemulsification Roberto Bellucci MD Chief of the Hospital Ophthalmic Unit Hospital and University of Verona, Italy FINANCIAL INTEREST: E

Stellaris – Efficiency Unique Handpiece Stellaris handpiece and CustomControl™ Software IIiled New 6-crystal configuration for enhanced ergonomics and balance – ideal for all hand sizes 28.5 kHz for optimised cavitation, and rapid emulsification with minimal thermal loading Precise control of power modulation for customised energy wave patterns and low overall phaco time Locking irrigation connectors for added safety

The Vacuum Fluidics Module Pioneering vacuum system for beyond “Venturi” responsiveness and aspiration efficiency Vacuum limit increased from 550 mmHg to 600 mmHg Advanced sensing technology accurately monitors and maintains targeted vacuum rise and intra-operative aspiration rate Air and fluid venting system Eliminates external gas supply using all electric design EQ VFM

StableChamber™ Tubing Safety Small diameter tubing increases resistance for high vacuum and steady low flow Internal mesh designed to capture material and prevent clogging Minimises variability in steady-state

The Dual Linear Control Pedal On demand independent linear control of aspiration and phaco power Wireless connectivity for operating room convenience With Dual Linear technology, the surgeon is able to achieve independent simultaneous control of vacuum and ultrasound. This affords simultaneous linear management of holding power and/or follow ability. The surgeon is able to control their adjustment to the “sweet spot”, which is excellent for the entire range of surgical techniques from divide and conquer to bi-manual phaco. The control with dual linear technology provides the opportunity for safety and efficiency throughout the procedure.

Standard Phaco 1.1 mm phaco needles are available with internal diameters 0.6-0.9 mm

My default settings Phaco power Vacuum Bottle height 90 cm to 120 cm Micropulse 10% max power, 85 pps, 35% duty cicle Vacuum 0.8-0.9 mm lumen 400-450 mm Hg Up to 0.7 mm 550-600 mm Hg Slow rise 3-4 Bottle height 90 cm to 120 cm

Results 100 consecutive surgeries Vacuum module Standard 1.1 mm needles with 0.6-0.9 mm internal lumen Cataract hardness 2.2+1.3 (1-4)

Results I case of chamber instability No chamber collapse Good holding and following ability No case of tubing clogging (the filter stops lens fragments)

Conclusions The new Stellaris phacoemulsification system is the ideal machine for both standard and 1.8 mm phacoemulsification Better fluidics control with 1.1 mm needles Better fluidics and phaco efficiency with 0.9 mm needles Improved safety
