Dry Eye Study (Study ID: PLUM)

Dry eye symptoms are commonplace. Dry eye is often managed with lubricating eye drops, stopping tears from draining or by stimulating tear production. Recently, there has been a shift toward focusing on nutrition for dry eye, especially with regard to oral antioxidants for relieving dry eye symptoms. This study will investigate the effectiveness of an oral supplement in form of a gummy bear containing blueberry powder.

The study consists of 3 in-office study appointments and 2 telephone calls, totaling 4.5 hours over 4 weeks.

What are the requirements?

  • You are at least 18 years of age.
  • You have dry eyes
  • You have not worn any contact lenses in the past 3 months
  • You have not used an oral supplement containing antioxidants in the past 3 months

Reimbursement

In appreciation of your time, you will receive $20 per hour you are involved in the study (up to $90). All study products will also be provided, and parking tokens are available for those who drive to their visits.

How to participate

If you are interested in participating, please email corestudies@uwaterloo.ca with the subject line “PLUM” or call 519-888-4742 for more information. You will be provided with all relevant study information prior to study enrollment and you are under no obligation to participate.

What are we trying to learn?

Xiidra (lifitegrast 5.0% ophthalmic solution) is a Health Canada approved eye drop that has been shown to be effective in relieving dryness symptoms in individuals with dry eye disease.
