Registry of PHAcoemulsification for Cataract Surgery

A nationwide registry will be established with a database of intraoperative data recorded during the cataract procedures performed with the Centurion phacoemulsifiers. The following intraoperative parameters used during the cataract surgery will be recorded and analyzed:

Primary endpoint: Ultrasound time (US time)

Exploratory endpoints:

• CDE : Cumulated dissipated Energy
• Total surgery time
• BBS volume
• Torsional and longitudinal energy
• IOP settings
• Vacuum settings Procedures performed with the Active Sentry module - where a pressure sensor is built in the phacoemulsifier handpiece will be compared to other to procedures performed without this module.

Data will be collected and analyzed from Centurions cases log extracted from at least 200 Centurions installed in France. Parameter and settings will be retrospectively analyzed.

A direct extraction of data from the machines will be processed for the analyses. No patient demographic data will be recorded.

The objective will be to capture data from at least 100,000 procedures and to run data analyses on a nationwide scale.

The database will serve as a basis to assess the technological advances aimed at reducing the amount of energy delivered in the eye, the duration of ultrasound use and overall the duration of procedures.

Inclusion criteria

• All procedures recorded in Centurions (200 machines).

Exclusion criteria

• Opposition of the center to data collection.
• Complicated surgery (e.g. anterior vitrectomy) identified as such in the event log
