Summary

This study compares two types of surgery for people with a detached retina. One group gets standard repair surgery, the other gets an extra step where a thin membrane is peeled away. Researchers want to see if this extra step lowers the chance of re-detachment and improves vision over one year. About 250 adults with a first-time retinal detachment are taking part.
