Every participant arrives with a summary

A study team opens its shortlist and reads what each person reported, what a document showed and what is left to confirm on site. Nobody phones through the criteria again.

Questions

What study teams and ethics reviewers ask first.

Does the AI decide a participant’s eligibility?

No. Fixed rules check each criterion, and the study team confirms at the first visit.

Does a participant get medical advice?

No. The assistant records answers and stops when someone reports a red-flag symptom.

What does a research team see before someone applies?

An anonymous count of profiles that roughly fit. A profile is shared only when its owner applies.

Does an eye clinic pay to be listed?

No. Providers are sorted by need and distance, and none has a paid place.

Who takes a participant’s informed consent?

The study team, face to face. EyeMatch records only consent to be contacted and pre-screened.

Eye care navigation when no study fits

A person who fits no study still leaves with a next step: how urgent it is, where to go and what to bring.

3 urgency levels, written by clinicians.
Guidance only, never a diagnosis.

Today, 9:41

My right eye went blurry suddenly this morning.

Please get care today. Sudden vision loss needs an eye doctor now, so I am stopping the screening. Red-flag rule

Where should I go?

The nearest Accident and Emergency department is open 24 hours. Show them your visit summary.

Can I still join a study later?

Yes. Add your diagnosis after the visit and your profile is matched again.

Thank you.
