What this trial studies

This clinical trial aims to evaluate the effectiveness of 0.01% hypochlorous acid (Avenova) compared to Betadine (povidone iodine) in reducing bacterial presence and improving patient comfort during eye procedures. The study focuses on treatment-naïve patients and those currently receiving intravitreal injections, assessing their responses to both antiseptic agents. By analyzing bacterial reduction and patient-reported discomfort, the trial seeks to identify a safer and more effective alternative to the commonly used Betadine, particularly for individuals with iodine allergies.

Who should consider this trial

Good fit: Ideal candidates include adults who are treatment-naïve or currently receiving intravitreal injections and can provide informed consent.

Not a fit: Patients who have received intravitreal injections in the past six months or have used certain eye drops may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a safer antiseptic option for patients with eye infections, particularly those allergic to iodine.

How similar studies have performed: While there have been studies comparing chlorhexidine and povidone iodine, the use of hypochlorous acid as an alternative is relatively novel and has not been extensively tested in this context.
