United States21 participantsStarted 2018-01-30
Plain-language summary
Tangible Hydra-PEG is a novel coating technology designed to improve lens wettability, deposit resistance, and tear film breakup time. This is a randomized double masked cross-over study to examine contact lens discomfort and dry eye symptoms with Tangible Hydra-PEG treated scleral lens wear compared to untreated scleral lens wear in the dry eye patient population.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Reduced tear film break up time (TBUT), a sign of dry eye disease and contact lens discomfort
* Scleral lens wearer (at least 8 hours per day for at least 5 days per week and have had their habitual lenses no longer than 1 year). Scleral lenses wear will be defined as 15.00 mm to 19.00 mm inclusive.
Exclusion Criteria:
* Disorders that affect sensitivity (herpetic disease, severe diabetes mellitus)
* Anatomic variations of the conjunctiva that can impair proper scleral lens fitting
* Pregnancy
* Best corrected Snellen visual acuity worse than 20/30 in either eye
* Ocular pathology other than dry eye (e.g. glaucoma, macular degeneration, keratoconus) which may significantly impact visual function.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
