Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study is testing whether a computer program called EpiMaster can accurately predict how well laser eye surgery (PTK-PRK) will correct nearsightedness. Researchers will compare the software's predictions to the actual vision results in 150 patients six months after surgery. The goal is to improve the accuracy of surgical planning.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
PTK-PRK refractive treatment (laser surgery)
What this could lead to
If successful, this could help doctors better predict vision outcomes after laser eye surgery for nearsightedness.
What could go wrong
This is an early-stage data collection study, not a treatment trial. The software predictions may not match actual results, and findings may not apply to all patients.
