Outcome Measures

Primary Outcomes (4)

  • Differences in energy during phacoemulsification between the methods investigated.

    Energy used during phacoemulsification is measured during each surgery. It is measured with the unit Cumulative Dissipated Energy (CDE).

    Immediately after the surgery

  • Differences in time used during phacoemulsification during surgery between the methods investigated

    Time, measured in seconds (s), will be measured from the start til the end of phacoemulsification

    Immediately after the intervention/procedure/surgery

  • Difference in corneal endothelial cell density after cataract surgery between the study groups investigated. Before and after surgery. Change is being assessed.

    During cataract surgery the participants loose some of the endothelial cells. The investigator can measure endothelial cell density (CD) with an endothelial cell camera. This will be done before and after surgery in both study groups.

    Pre-intervention surgery and 14 days after surgery.

  • Measurement of clinical och subclinical macular oedema before and after surgery. Change is being assessed.

    Clinical or subclinical macular oedema is a known complication to cataract surgery. Macula will be measured with an Ocular Coherence Tomography (OCT) before and after surgery. Retinal thickness in macula will be measured in micrometer. Data is collected after each surgery from the phaco apparatus throughout the study.

    Pre-intervention surgery and 14 days after surgery.
