Outcome Measures
Primary Outcomes (1)
Assessment of post-intravitreal injection eye pain
Demonstrate the superiority of IRX-101 compared to PI in terms of reducing patient-reported post-intravitreal injection eye pain; pain will be assessed using the visual analog pain scale, a validated patient-reported outcome measure (questionnaire) for assessing patient's subjective pain and discomfort
Demonstrate a reduction in mean 1-hr post-injection pain scores
Secondary Outcomes (1)
Change in post-IVT corneal epitheliopathy as evaluated by corneal fluorescein staining scores
Immediately following intraviteral injection
Study Arms (2)
IRX-101
EXPERIMENTALSubjects randomized to IRX-101 will receive the investigational product, IRX-101.
5% Povidone-iodine
ACTIVE COMPARATORSubjects randomized to this arm will receive the standard of care, Providone-iodine, at a concentration of 5%.
