Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 to 80 who are scheduled for cataract surgery on their second eye and do not have contraindications to XANAX.

Probably not a fit

Patients with severe corneal diseases, contraindications to surgery, or those who do not experience preoperative anxiety may not benefit from this study.

What this trial studies

This study investigates the effects of the oral anti-anxiety drug XANAX on patient satisfaction, anxiety, and pain during phacoemulsification cataract surgery. It aims to determine whether oral sedation can provide a safer and more convenient alternative to intravenous sedation, which is commonly used but carries additional risks. Patients undergoing surgery on their second eye will be monitored for their anxiety levels, pain experiences, and overall satisfaction with the procedure. The study will compare outcomes between those receiving XANAX and those receiving a placebo.

Why it matters

Potential benefit: If successful, this study could lead to improved patient comfort and satisfaction during cataract surgery.

How similar studies have gone: Previous studies have shown varying success with oral sedation in surgical settings, but the specific use of XANAX in cataract surgery is less explored.
