Further study details as provided by Alcon Research:

Primary Outcome Measures:
  • Patients were asked to rate the level of pain in each eye for the first three to five days after surgery.

Secondary Outcome Measures:
  • Also, patients were examined daily for the first three to five days until corneal epithelial closure to evaluate the rate of epithelial healing.
