Primary Outcome Measures
NameTimeMethod
Visual Analog Scale (VAS) Pre-dose Pain Assessment6 hours

VAS pain severity scale pre-dose, 6 hours post-operatively. The Visual Analog Scale (VAS) is a commonly used measurement of pain, discomfort, that goes from 0 meaning no pain to 100 meaning worst imaginable pain

Average Ocular Pain VAS Assessments12 hours

VAS pain severity scale from the first post-operative assessment to pre-dose 12 hours post-operative assesment The Visual Analog Scale (VAS) is a commonly used measurement of pain, discomfort, that goes from 0 meaning no pain to 100 meaning worst imaginable pain

Secondary Outcome Measures
NameTimeMethod
VAS Pain Assessments72 hours

VAS pain assessment during the first 72 hours post-operatively. VAS pain severity scale from the first post-operative assessment to pre-dose 12 hours post-operative assesment The Visual Analog Scale (VAS) is a commonly used measurement of pain, discomfort, that goes from 0 meaning no pain to 100 meaning worst imaginable pain
