Outcome Measures

Primary Outcomes (4)

  • Changes in post-operative outcome of pain

    By assessing the amount of pain on a visual analogue scale (score 0 - 9)

    1 week

  • Changes in post-operative outcome of redness

    Scoring the amount of redness on a scale 0-4 through eye photos

    1 week

  • Changes in post-operative outcome of measured inflammation

    Measuring the amount of inflammation by measurement of Flare (photon/ms)

    1 week

  • Changes in post-operative outcome in grading of anterior chamber cells

    Clinical assesment by slit lamp (Tyndall 0 - 3 and Cells 0 - 3)

    1 week

Secondary Outcomes (3)

  • Post-operative parameter: Visual acuity

    1 week

  • Post-operative parameter: Intraocular pressure

    1 week

  • Post-operative parameter: Pain assessment

    1 week
