Study ID: BLUEBERRY #2

The objective of this study is to evaluate the performance of new prototype contact lenses, with particular focus on comfort.  These lenses have been modified in an attempt to enhance the tear film around the lens, with the ultimate goal to improve comfort.

About the study

This study involves 5 study visits across a lens wear period of 2 weeks.  The study visits are:

Visit #1 & 2: (normally both visits are combined) – Screening visit to determine eligibility (1.5 hours)  and dispensing of study lenses (1 hour) – 2.5 hours total

Visit #3 & 4: (normally both visits are combined) – Follow up visit (1 hour) and dispensing of study lenses (1 hour) – 2 hours total

Visit 5: End of study visit and study exit  – 1 hour

Total in-visit time commitment5.5 hours

You will also be asked to complete 2 short questionnaires during the study (10 minutes in total).

The visits will include standard clinical procedures that you might encounter when you attend an eye exam.

Participant requirements

To be eligible for this study, you must meet the following criteria:

  • You are 18 years of age or older
  • You can be fit with the study contact lenses
  • You habitually wear soft, spherical contact lenses for at least 6 hrs/day, 3 days/week
  • You are willing to wear the study contact lenses for at least 8hrs/day, 5 days/week for the duration of the study
  • You own a pair of glasses that permit participation in daily activities, including safe working and driving.

Reimbursement

In appreciation of your time, you will receive $110 upon study completion

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.

New study on gel lubricants for dry eye (Study ID: JELLYFISH)

Most patients with dry eye disease use a lubricating eye drop to relieve symptoms of dryness. The relief gained from using drops can be short as the drops spill out of the eyes or drain away quickly from the eye surface. The aim of this study is to evaluate the comfort of a gel lubricant in participants with moderate dry eye disease. Once applied to the eye, the gel lubricant slowly dissolves over 60-90 minutes. In this study, eligible participants will experience 4 different sizes of gel lubricants (one gel lubricant per study day) and one commercially available ocular lubricating eye drop, Systane Ultra Hydration Preservative-Free.

About the study

This study will involve one screening visit to determine eligibility for the study. Eligible participants will attend CORE for 5 study treatment days to receive either gel lubricant or the ocular lubricating drop. After all 5 study treatment days are complete, participants will return for a final visit to exit the study.

There will be a 1-7 day gap between the study visit days

Visit 0- Screening visit to determine eligibility – 1.5 hours

Day 1: Visit 1 – Receive gel lubricant or eye drops and assessment after application – 5.5 hours

Day 2: Visit 2 – Receive gel lubricant or eye drops and assessment after application – 5.5 hours

Day 3: Visit 3 – Receive gel lubricant or eye drops and assessment after application – 5.5 hours

Day 4: Visit 4 – Receive gel lubricant or eye drops and assessment after application – 5.5 hours

Day 5: Visit 5 – Receive gel lubricant or eye drops and assessment after application – 5.5 hours

Day 6: Visit 6 – Study exit – 1.25 hours

You will also be asked to complete some home questionnaires on each study day (totaling 1 hour over the duration of the study)

Total time commitment for visits 30.25 hours over 10-30 days

The visits will include standard clinical procedures that you might encounter when you attend an eye exam.

What are the requirements?

  • You are at least 18 years of age.
  • You experience symptoms of dry eyes
  • You do not wear contact lenses
  • You use eye drops 2-4 times per day for the past 60 days

Reimbursement

In appreciation of your time, you will receive $20 per hour you are involved in the study (up to $625 upon completion). All study products will also be provided, and parking tokens are available for those who drive to their visits.

New contact lens study for young adults (Study ID: MULBERRY)

Despite improvements in contact lens materials, many contact lens wearers commonly report symptoms such as discomfort by the end of the day. It has been suggested that daily disposable Myopia, or nearsightedness, occurs when the eye is too long and typically worsens as children and young adults grow. The goal of myopia control treatment is to slow this progression, reducing the risk of vision threatening problems later in life. One example of myopia control is the MiSight contact lens, which has been shown by previous research to reduce myopia progression in children aged 8-12. Since some individuals see myopia progression up to age 25, this study is investigating if individuals aged 17-25 can achieve comfort and vision satisfaction with the MiSight lens.

About the study

This study consists of 4 in-office appointments and 1 at home remote questionnaire, over 3 months.

Visit 1 & 2: Screening, baseline measurements and dispense of study lenses – 1.5 hours

Visit 3: 2 week follow up – 1 hour

Visit 4: 1 month follow up – 1.25 hours

Visit 5: 2 month follow up, remote at home questionnaire – 0.25 hours

Visit 6: 3 month follow up and study exit – 1.5 hour

Total time commitment5.5 hours

The study visit includes standard procedures that would often be encountered during a regular eye exam. Please note that physical distancing cannot be guaranteed during all procedures but will be maintained whenever possible.

What are the requirements?

To be eligible for this study, you must meet the following criteria:

•             Aged 17-25

•             Currently wearing soft contact lenses

•             Prescription between -0.75 and -6.00 D, with no more than -0.75 D of astigmatism in each eye

Reimbursement

In appreciation of the time involved, you will receive $20 per hour, or $110 upon study completion. Parking passes will be provided as required.
