The SNEC DSAEK EndoGlide Clinical Trial

Singapore100 participantsStarted 2010-01

Plain-language summary

The purpose of this study is to determine the clinical safety and efficacy of the EndoGlide as a donor insertion device in DSAEK surgery. The investigators hypotheses is that the Endoglide will cause less endothelial damage compared to the investigators previous technique of glide insertion but will have the same low complication rate as the previous device. Hence the investigators aim to evaluate the surgical efficacy of the EndoGlide to enable consistent double coiling of the donor lenticule in DSAEK surgery with minimal endothelial touch. Evaluate ease of insertion of the EndoGlide through a 4 to 4.5mm scleral tunnel wound. Evaluate ability of the EndoGlide to consistently effect complete wound sealing, so as to stabilize anterior chamber with an AC maintainer in position. Evaluate ease of donor pull-through from the EndoGlide chamber into the AC and to evaluate spontaneous uncoiling of the donor in the AC. Evaluate clinical efficacy and safety outcomes in EndoGlide assisted DSAEK surgery in study patients with corneal decompensation requiring DSAEK surgery, in terms of postoperative visual acuity, primary graft failure rate, donor dislocation rate, endothelial cell loss, and deturgescence of the host cornea and donor lenticule as measured by corneal thickness parameters with the Visante AS-OCT. The investigators will perfprm a prospective Phase II clinical trial using the EndoGlide for donor insertion in 100 corneal patients referred to the SNEC Corneal Clinics of the study investigators with moderate degrees of corneal decompensation from a variety of disorders which require DSAEK corneal transplantation surgery, with or without concurrent cataract surgery, to restore visual acuity.

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.
