Outcome Measures

Primary Outcomes (1)

  • Recruitment rate

    The study has been designed as a feasibility study to assess recruitment rate. We will measure rate of recruitment to study (persons per month)

    From the start to the end of the 10 month planned recruitment period

Secondary Outcomes (2)

  • Retinal thickness on SD OCT

    Between baseline and day 40

  • Foveal avascular zone size on optical coherence tomography angiography between baseline and day 40

    Between baseline and day 40

Study Arms (2)

Standard pressure

ACTIVE COMPARATOR

Infusion pressures during phacoemulsification surgeon using the Alcon active sentry system with the Centurion - 70mmHg

Device: Centurion Phacoemulsification System

Low or physiological pressure

ACTIVE COMPARATOR
