MERGE Contact Lens Study

This study is now closed to enrollment

Why we are doing this study:
The purpose of this study is to learn more about differences in genes (DNA), bacteria, and proteins in the tears of soft contact lens wearers with and without a history of eye inflammation/infection.

Who can be in the study?

  • Patients 18 to 40 years of age.
  • Healthy soft contact lens wearers and those who had a doctor diagnosis of a corneal inflammatory event (white blood cells in the cornea)

What the study involves:
There is only one visit, lasting approximately 2 hours. During the visit we will:

  • Ask you questions about your general and eye health, and how you wear and care for your contact lenses
  • Conduct an examination of the front surface of your eye
  • Collect tears and cultures (swabs) from the front of your eye
  • Draw a small sample of blood from your arm

Will you directly benefit from the study?
Being in this study won’t directly benefit you but it may help us learn more about contact lens complications so we can better educate and care for future patients.

Other things you should know about the study:
You will receive up to $75 for your time to be in the study.
