I. Laser system features impact clinical outcomes and dictate usage in challenging cases and old patients.

A. Catalys Precision Laser System (Sunnyvale, Calif., USA)
B. Patient interface
C. Imaging modalities
D. Image guidance
E. Laser technology

Extensive grid fragmentation pattern creates capability to eliminate ultrasound energy.

II. Results

A. Successful treatment of patients with comorbidities and challenging cases
B. Limited complication rate in 1900 consecutive cases with comorbidities
C. Previously, showed 96% reduction in effective phacoemulsification time
D. In 1900 consecutive cases, rate of complete capsulotomy: 99%
E. Analysis of 1900 case consecutive series showed >40% requiring zero ultrasound
F. Reduced endothelial cell loss and faster visual recovery
G. Improved BCVA

III. Conclusions

A. Catalys’ key features enable successful laser cataract surgery in challenging cases, allowing improved clinical outcomes in all patients and revolutionary new procedures.
B. Limited complication rate observed in consecutive case series with high percentage of comorbidities
C. High rate of complete capsulotomy
D. Lens fragmentation results in elimination of ultrasound in large percentage of cases.
E. Reduction in endothelial cell loss and faster visual recovery with Catalys
