Plain-language summary
Trachoma, an ocular infection caused by C. trachomatis, is the second leading infectious cause of blindness worldwide. Years of repeated infection with C. trachomatis cause the eyelid to scar and contract and ultimately to rotate inward such that the eyelashes rub against the eyeball and abrade the cornea (trichiasis). The World Health Organization (WHO) has endorsed a multi-faceted strategy to combat trachoma which includes surgery to repair lids distorted by trachoma (trichiasis) in imminent danger of vision loss. Current evidence suggests that long-term success rates of trichiasis surgery are less than optimal due to variation in surgical technique. Previous research by this study team has demonstrated that shorter incisions have a higher rate of trichiasis recurrence. In addition, observations by this team's oculoplastic surgeon have led to the hypothesis that granuloma formation and lid contour abnormalities may result from current surgical practices. The objective of this study is to compare outcomes of trichiasis surgeries performed with the newly developed trachomatous trichiasis (TT) clamp versus surgeries following standard technique (bilamellar tarsal rotation procedure or BLTR).

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Presence of upper lid trichiasis: defined by at least one eyelash touching the globe of the eye or evidence of epilation
* No previous report of trichiasis surgery in at least one eye with trichiasis:
* eyes with prior surgery are already at high risk due to the prior surgery, and their inclusion may decrease our ability to clearly evaluate our primary outcome
* if unilateral surgery has been performed previously, only the eye without prior history of surgery will be in the study, even if both eyes require surgery
* Age 18 or older (in order to provide consent as an adult): the vast majority of trichiasis patients are aged 18 or older
* At time of enrollment, subjects must state their intention to remain in the area for two years to facilitate study follow-up
Exclusion Criteria:
* Absence of upper lid trichiasis
* Prior trichiasis surgery on both eyes
* Age 18 or younger
* Subjects who are transiently in the area
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?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
