AMO SOVEREIGN COMPACT Phacoemulsifier
The system was developed by Advanced Medical Optics (AMO), an ophthalmic equipment company whose surgical business later became part of Johnson & Johnson Vision.
Key features and functions
1. Ultrasonic phacoemulsification
Uses an ultrasonic handpiece to fragment the cloudy lens and aspirate the resulting material through a small surgical incision.
2. WHITESTAR technology
Provides controlled ultrasonic energy delivery to support efficient lens removal while helping manage energy exposure during surgery.
3. Irrigation and aspiration system
Maintains fluid flow within the eye and removes lens fragments and residual cortical material to support intraoperative chamber stability.
4. Surgeon controls and operating modes
Features a foot pedal, display interface and programmable settings. Depending on configuration, operating modes include phacoemulsification, irrigation/aspiration, bipolar diathermy and vitrectomy.
These features are described in the system’s operator documentation and product information.
Main applications
-
Cataract extraction in ophthalmic operating rooms.
-
Ultrasonic fragmentation and removal of the natural lens.
-
Removal of residual lens cortex through irrigation and aspiration.
-
Selected anterior-segment surgical procedures using compatible accessories and supported configurations.

Important considerations when purchasing a used unit
Because the SOVEREIGN COMPACT is an older system, verify the unit’s operating condition, service history, software and hardware configuration, compatible handpieces, foot pedal, fluidics packs, and availability of replacement parts. Confirm that all required accessories are included and that the system can be serviced locally.
