You might remember that in an earlier blog post we talked about designing a contact lens to help diagnose glaucoma. It will be able to continuously monitor pressure within the eye, giving a much more dynamic picture of eye pressure than a snapshot test in a clinic. Well, we have made progress and are now looking for volunteers to test the lens. Can you help?

We need to be sure that the contact lens is comfortable and returns reliable eye pressure readings, and need healthy volunteers to test it for us. We are looking for people from all walks of life, aged 18 years or over, who are in good general and eye health with corneal and refractive astigmatism within ±0.50 dioptres cylinder. You should have no history of eye surgery or full-time rigid contact lens wear.

It is really easy to take part. You just arrive at our clinic where you will undergo routine eye examinations, and you will then be fitted with a contact lens. You will wear the lens for one hour, after which you will fill out a questionnaire on how comfortable it was to wear. The tests for suitability to participate will take approximately 1.5 hours while the main study will take up to 5 hours, so you aren’t expected to commit more than 7 hours to the study. You will be reimbursed up to £75 per visit to cover travel and subsistence costs, for up to a total of 2 visits.

If you can help you will be contributing to our efforts to fight glaucoma, the world’s leading cause of irreversible blindness which affects more than 500,000 people in the UK alone. This really is vital work.

Please email Andrea Madden with your contact details. Andrea will then call you for a chat and will give you all the information you need.

The development of this contact lens is being funded by the National Institute for Health Research i4i programme.
