About this study
Official title: A Single-Center, Prospective, Single-Arm Clinical Study Evaluating the Safety and Efficacy of Corneal Preservation Solution
The goal of this clinical trial is to learn if a corneal preservation solution can safely and effectively preserve donor corneas for corneal transplantation in patients who need penetrating keratoplasty (PKP) or endothelial keratoplasty (EK). It will also learn about the safety of this corneal preservation solution. The main questions it aims to answer are:
What is the donor viability rate on the day of transplantation, defined as the proportion of donor corneas with endothelial cell density (ECD) ≥2,000 cells/mm²? What is the corneal graft transparency rate 14 days after transplantation? What medical problems do participants have after transplantation? This is a single-center, prospective, single-arm study. Researchers will enroll 60 patients at Shandong Provincial Eye Hospital (Affiliated Eye Hospital of Shandong First Medical University). All participants will receive a donor cornea preserved in the corneal preservation solution for 2-7 days. Donor corneal ECD and hexagonality will be measured at the time of donor retrieval and on the day of transplantation. Donors with ECD ≥2,000 cells/mm² can be used for transplantation. Participants will be followed for 14 days after transplantation. There is no comparison group.

Participants will:
Undergo PKP or EK using a donor cornea preserved in the corneal preservation solution for 2-7 days.
Have donor corneal ECD and hexagonality measured before transplantation. Be followed for 14 days after transplantation for graft transparency, ECD, graft thickness, epithelial healing, visual acuity recovery, secondary surgery, and adverse events.
The results will provide evidence for the formal clinical use of this corneal preservation solution in China.

Corneal preservation solution used to preserve donor corneas for 2-7 days before PKP or EK.
| Study group | Role | What they receive |
|---|---|---|
| Corneal Preservation Solution Group | Experimental | Participants with corneal diseases requiring penetrating keratoplasty (PKP) or endothelial keratoplasty (EK) receive a donor cornea preserved in the corneal preservation solution for 2-7 days. Donor corneal endothelial cell density (ECD) and hexagonality are measured at the time of donor retrieval and on the day of transplantation. Only donor corneas with ECD ≥2,000 cells/mm² are used for transplantation. All participants are followed for 14 days after transplantation. The primary outcomes are the donor viability rate on the day of transplantation and the corneal graft transparency rate at 14 days after transplantation. Secondary outcomes include donor corneal endothelial hexagonality, ECD, graft thickness, graft epithelial healing, visual acuity recovery, secondary surgery (retransplantation) rate, and adverse events.

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Donor Corneal Viability Rate (time frame: On the day of corneal transplantation). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Oct 2026.
