Comparing two drugs for numbing the eye before tear-duct surgery
Treatments studied
Part of Eyes & vision clinical trials.
This trial tests whether adding dexmedetomidine or magnesium sulfate to lidocaine makes numbing the eye more effective for tear-duct surgery. The goal is to find which combination provides better pain control during surgery.
