ClinConnect Summary

This clinical trial is studying two different ways to numb the eye during pterygium surgery, which is a procedure to remove a growth on the eye's surface. The researchers want to compare the use of a gel called lidocaine with a traditional method that involves an injection of a numbing medicine called xylocaine. They believe that the gel might be less painful and provide better comfort during the surgery, while also helping to keep the eye surface moist and less dry afterwards.

To participate in this trial, you need to be someone who requires pterygium excision surgery and is between the ages of 18 and 75. However, if you have certain health conditions like autoimmune diseases or have had prior pterygium surgery, you may not be eligible. If you join the trial, you can expect to share your experience of pain during and after the surgery, as well as any dryness in your eyes. This study aims to help improve comfort for future patients undergoing this type of eye surgery.
