ZEISS QUATERA 700: A Comparative Analysis of Chamber Stability
Fanney D, et al. Journal of Cataract & Refractive Surgery 2023
The QUATERA® 700 from ZEISS represents a significant advancement in cataract surgery, utilizing the patented ZEISS QUATTRO Pump® to achieve stable chamber conditions independent of intraocular pressure (IOP) or aspiration flow.
A study conducted using a laboratory-based spring eye model compared intraocular pressure (IOP) against variations in aspiration flow rate (AFR) and incision leakage for two different phaco systems.
Results and Observations
Chamber Stability Score
During surgery, ZEISS QUATERA 700 achieved significantly higher mean chamber stability scores in both soft and dense cataract groups compared to Competitor A & Competitor B.
Total Phaco Time (TPT)
The measurement obtained with ZEISS QUATERA 700 was significantly lower compared to that of Competitor A within the dense cataract patient group.
Mean fluid turnover
Significantly lower for the ZEISS QUATERA 700 compared to Competitor A within the dense cataract group.
Combined phaco and I/A time
The combined phacoemulsification and irrigation/aspiration (I/A) time recorded for ZEISS QUATERA 700 was notably lower compared to that of Competitor A in the dense cataract patient group.
Obsevation
In cases of soft cataracts, posterior capsule rupture (PCR) occurred in one eye each operated with Competitor A and Competitor B, both attributed to intraoperative surge. Similarly, in the dense cataract group, one eye treated with Competitor B also experienced PCR due to sudden surge. In contrast, the ZEISS Quatera 700 showed no instances of PCR related to chamber instability, highlighting its enhanced fluidics and chamber stability across cataract types.
