This cluster randomized controlled trial aims to evaluate the effectiveness of a Structured Referral Tracking (SRT) intervention in improving referral completion among adults identified with avoidable blindness during community-based eye screening camps in Rawalpindi District, Pakistan. Ten community clusters will be randomized into intervention and control groups. Participants in the intervention group will receive structured referral counseling, weekly reminder calls or messages, and customized referral guidance for eight weeks, while the control group will receive standard referral procedures. The primary outcome is referral completion at a tertiary eye hospital within eight weeks after screening. Secondary outcomes include knowledge regarding avoidable blindness, treatment satisfaction, feasibility, acceptability, and barriers influencing referral completion.
