What You Need to Know Before You Apply

What is the purpose of this trial?

This randomized controlled trial evaluates whether a standardized perioperative neuroplastic intervention: the STEIN Protocol (Strategies and Techniques for Enhancing Integration and Neuroplasticity), consisting of pain neuroscience education, guided imagery, and paced breathing, reduces intraoperative analgesic and anxiolytic requirements.

Secondary outcomes include patient-reported pain, anxiety, satisfaction, and postoperative recovery following cataract surgery.

Reduced intraoperative sedative and analgesic requirements may reflect improved patient comfort and autonomic regulation while minimizing medication-related adverse effects.

Are You a Good Fit for This Trial?

This trial is for adults having planned cataract surgery with numbing eye drops who can give consent and follow study instructions. People can't join if they have certain medical or mental health issues, need special anesthesia, or can't do the breathing exercises or follow-up.

  • STEIN Protocol

Trial Overview

The study compares three groups: one gets a neuroplasticity-based program (education about pain, guided imagery, and paced breathing), another listens to music only, and a control group receives standard care. The goal is to see which approach best reduces anxiety and pain during cataract surgery.
