B & L Stellaris
Stellaris – EfficiencyStellaris – EfficiencyUnique Dual-Linear TechnologyUnique Dual-Linear Technology
• On-demand independent linear control of aspiration and phaco power
• Pre-programmable foot pedal settings customizable to surgeon technique
• Surgeon control of total phaco time for added safety and efficiencythroughout procedure
• Wireless connectivity for OR convenience
Stellaris Handpiece
• Six-crystal configuration
• 28.5 kHz for optimized cavitation, and rapid emulsification with minimal thermal loading
• SureLockTM Locking irrigation connectors
• C-MICS and B-MICS capable
Conventional power modulation
Advanced power modulation with CCS
Traditional pulse: 20 pps Hyperpulse: up to 120 pps-more effective cutting with
less heat
Traditional burst: minimum of 80 ms
Hyper burst: minimum of 4 ms- less energy w/ nuclear removal- less heat build-up- less total energy
Extended range of programmability vs. conventional pulse and burst modes
Custom Control Software (B&L)Custom Control Software (B&L)
Conventional Advanced power modulation
with CCS
Fixed duty cycle Variable duty cycle (10 – 100%)-To prevent continuous phaco energy even w/ maximum pedal depression
Fixed rise time Variable rise time (waveform pulse)
Unique to Millennium technology- less energy during nuclear removal- less heat build-up; less total energy
Variable Duty Cycle, Rise TimeVariable Duty Cycle, Rise Time
Stellaris Handpiece –Stellaris Handpiece –Cutting Dynamics Cutting Dynamics
• Increased stroke length for efficient cutting of the nucleus
• Tighter, more focused and consistent delivery of stroke
• CustomControl Software II for customizable, programmable wavefront power modulations for all techniques
Alcon Infiniti
Torsional Phacoemulsification
• New energy delivery modality on the INFINITI® Vision System designed to– Reduce repulsion and turbulence– Improve thermal safety profile
• Oscillatory motion at the hub of the phaco tip similar to NeoSoniX® with lower frequency than traditional ultrasound– NeoSoniX® oscillations 100 Hz– Torsional phaco 32,000Hz – Traditional Longitudinal phaco 40,000Hz
Ozil Reverse Kelman Tip
Power Modulations
• Provide millisecond level control of US
• Reduce repulsion, improve followability (with transversal or torsional motion delivery)
• Minimize thermal energy, free radical production
• Facilitate B-MICS
