Further study details as provided by Wenzhou Medical University:

Primary Outcome Measures:
  • Pupil size after intracameral adrenaline [ Time Frame: 1day ] [ Designated as safety issue: No ]
    We would like to evaluate Pupil size dilated with intracameral adrenaline 0.01%

Secondary Outcome Measures:
  • endothelial cell count [ Time Frame: 1month ] [ Designated as safety issue: Yes ]
    we would like to evaluate the endothelial cell count 1 month after surgery
