Outcome Measures

Primary Outcomes (1)

  • Corneal Endothelial Cell Loss

    Endothelial cell loss/gain is measured by comparing the preoperative assessment of endothelial cell density against postoperative measurements. Measurements are made with a specular microscope, which takes a picture and numbers endothelial cells. This endpoint compares the assessment done at 1 month against the assessment done at baseline. A negative number indicates a loss of endothelial cells, a positive number indicates a gain in endothelial cells.

    1 month

Secondary Outcomes (5)

  • Intraocular Pressure (IOP)

    1 Day Postoperative

  • Aqueous Signs - Cells

    1 Day Postoperative

  • Aqueous Signs - Flare

    1 Day Postoperative

  • Aqueous Signs - Edema

    1 Day Postoperative

  • Surgeon Survey
