Numbing patch comparison before blood draw for eye care
Part of Eyes & vision clinical trials.
This trial tests a numbing skin patch made with tiny microneedles against a standard numbing cream/patch to reduce pain before a blood draw. It may help you feel less discomfort during venepuncture before an eye procedure.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You need a blood draw (venepuncture) for blood tests before an eye (ophthalmology) procedure.

This trial tests a special marker that numbs the skin before medical procedures. It may help reduce pain during injections or minor skin treatments.
This study tests two methods, a mild electrical nerve stimulation and a vibrating device, used during the numbing injection for skin surgery to see if they reduce pain. Participants will be randomly assigned to one of the methods during their procedure.
This study compares two ways to numb the skin before placing an epidural needle: a lidocaine patch placed on the back versus a lidocaine injection under the skin. The goal is to find which method is more comfortable for pregnant women during labor or cesarean delivery.
This trial tests how long numbing medicine lasts when applied to the nose and forearm. You will receive the study treatment on both sides of your face and arms to compare the effects.
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.
