La description
Inclusion Criteria:
You must meet all the following inclusion criteria to participate in the study:
- Patients with corneal stromal defects, including those caused by trauma or following lesion excision for infection, with a residual stromal thickness of ≥300 μm in the defect area.
- Patients aged 18 to 85 years (inclusive, either sex) at the time of consent.
- Patients who are capable of providing written informed consent voluntarily to participate in the study.
Exclusion Criteria:
You will be excluded from the study if you meet any of the following exclusion criteria:
- Patients with unexplained keratoconjunctival diseases.
- Patients with severe dry eye, symblepharon, corneal neovascularization, or other ocular surface disorders.
- Patients with systemic infectious diseases (positive for bacteria/fungi/HBV/HCV/HIV/TP, etc.).
- Patients with autoimmune diseases such as rheumatoid arthritis, Sjögren's syndrome, or graft-versus-host disease.
- Patients with uncontrolled ocular diseases in the study eye.
- Patients with major organ failure or other serious systemic conditions, including but not limited to cardiac insufficiency; poorly controlled diabetes mellitus (fasting blood glucose >8 mmol/L despite glucose-lowering therapy); uncontrolled stage II or higher hypertension (blood pressure >160/100 mmHg despite antihypertensive therapy); history of malignancy within the past 5 years; severe immunodeficiency, etc.
- Patients with psychiatric disorders that may interfere with treatment or evaluation.
- Pregnant or lactating women, or women planning to become pregnant during the clinical study.
- Patients deemed unsuitable for participation in the clinical trial by the investigator.
- Patients unable to complete follow-up visits.

Expérimental: Sutureless Ophthalmic Hydrogel for Repairing Corneal Stromal Defects
|
Surgery was performed under peribulbar block anesthesia.
After excision of the corneal lesion, the surface moisture of the recipient bed was dried with a sponge, and a cotton pad was placed over the pupillary area to protect the fundus.
The hydrogel was pre-liquefied in a 37 °C water bath, then instilled into the lamellar defect using a sterile syringe, followed by irradiation with a 365 nm light source at an intensity of 18 mW/cm² for 30 seconds to achieve curing.
A bandage contact lens could be applied.

Description de la mesure |
Délai |
|---|---|---|
|
Incidence of Ocular Adverse Events and Hydrogel-Related Ocular Complications (Irritation, Displacement, Infection, Corneal Cell/Epithelial Changes)
Délai: 1st day, 1st week, 2nd week, 1st month and 2nd month postoperatively
|
Description: Assess ocular safety outcomes including:
|
1st day, 1st week, 2nd week, 1st month and 2nd month postoperatively

Délai |
|---|---|---|
|
Corneal Clarity Full Rating Scale (0-4 points full-scale assessment for corneal transparency after hydrogel repair)
Délai: 1st day, 1st week, 2nd week, 1st month and 2nd month postoperatively
|
Observe the transparency of the cornea in the hydrogel transplantation area using a slit lamp examination, score it, and record the corneal transparency scores at different follow-up time points. Full scale information: Minimum score = 0, Maximum score = 4; higher scores indicate worse corneal opacity/poorer corneal clarity, lower scores indicate better corneal transparency. Scoring criteria: 0 = completely transparent;
|
1st day, 1st week, 2nd week, 1st month and 2nd month postoperatively
|
|
Change in corneal thickness (OCT measurement, µm)
Délai: 1st day, 1st week, 2nd week, 1st month and 2nd month postoperatively
|
Use corneal OCT to observe changes in corneal thickness in the hydrogel transplantation area, and record the residual corneal thickness, hydrogel thickness, and total corneal thickness at different follow-up time points.
|
1st day, 1st week, 2nd week, 1st month and 2nd month postoperatively
|
|
Change in visual acuity (decimal chart)
Délai: 1st day preoperatively, 1st day, 1st week, 2nd week, 1st month and 2nd month postoperatively
|
Use a decimal visual acuity chart to record the visual acuity and best corrected visual acuity at different follow-up time points, and evaluate the recovery and changes in visual acuity
|
1st day preoperatively, 1st day, 1st week, 2nd week, 1st month and 2nd month postoperatively
