A Single-Center Clinical Study to Evaluate the Efficacy and Safety of Sutureless Ophthalmic Hydrogel for Corneal Wound Repair

Sponsor: Suxia Li

View on ClinicalTrials.gov

Summary

Corneal blindness is one of the leading causes of blindness worldwide. For various infectious and non-infectious corneal diseases, current clinical repair strategies include corneal lesion debridement, conjunctival flap coverage, amniotic membrane transplantation, corneal transplantation, contact lens application, and injectable sealants. Injectable hydrogels, as smart materials that transition from a liquid precursor to a solid gel in response to external stimuli (e.g., light, temperature, or chemical cross-linking), enable precise filling of corneal defects via minimally invasive injection. They offer superior morphological adaptability, conforming tightly to irregular wound surfaces and achieving sutureless closure. Moreover, they promote regenerative repair of the epithelium, stroma, and nerves, significantly reducing patient discomfort, infection risk, recovery time, and healthcare costs, thereby advancing the paradigm of corneal repair from "transplant substitution" to "in situ regeneration."

Sutureless Ophthalmic Hydrogel for 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.
