What researchers measure

Primary outcomes

  1. Rate of sight-threatening adverse events

    Time frame: 36 months

Secondary outcomes

  1. Other adverse events

    For other adverse events such as increase in intra-ocular pressure (IOP) of ≥ 10 mmHg at any time postoperative, loss of best spectacle corrected visual acuity of ≥ 2 lines (≥ 10 letters) postoperative as compared to baseline or best recorded visual acuity measured at any visit postoperative, the rate of each event at each visit will be calculated for the two treatment groups separately.

    Time frame: 36 months

Other outcomes

  1. Diurnal IOP reduction ≥ 20%

    Time frame: Baseline and 24 months
