Increased Stability During Phacoemulsification

 

LEGION® System offers better surge protection than INFINITI® at various vacuum limits, reducing the risk of PCR and capsule related problems.1-6

 

Surge Protection with Gravity Fluidics Systems7

 

 

A line graph comparing surge protection with various gravity fluidics systems. INFINITI System had the highest levels of surge at all vacuum levels and CENTURION Silver System had the lowest surge levels at all vacuum levels. LEGION System’s surge volume was higher than CENTURION Silver System but lower than INFINITI System at all vacuum levels.

Surge Volume After Occlusion Break8

(IOP 55 mmHg; Vac setting 550 mmHg; Asp 40 cc/min; 55 mmHg = 75 cm H2O)

 

 

A line graph comparing the Surge Volume After Occlusion Break with LEGION System and INFINITI System with IOP at 55 mmHg. LEGION System had 30% less surge and 50% faster recovery from surge.

 

 

  • 50% faster recovery from surge 
  • 30% less surge

    Total phaco needle time9    
    Nuclear sclerosis grade 3 and 4 

     

    A bar graph comparing the mean total phaco needle time of OZil Torsional and transversal ultrasound systems. OZil Torsional had a 32.4% lower phaco needle time compared to transversal and this difference was statistically significant.

     

    P value * = statistically significant

    LEGION® System uses OZil® Torsional, allowing for reduced phacoemulsification time compared to Stellaris† longitudinal ultrasound technology, especially on higher grade cataracts.9
