摘要：Corneal wound closure for surgical eye surgeries or accidents is typically performed to prevent pathogens from the sterile intraocular environment and avoid potential postoperative complications.Tissue adhesives are increasingly employed for corneal wound closure with superior treatment efficiency and less adverse effects.In this study,we successfully develop a novel corneal adhesive based on functionally coupled PEG-lysozyme(PEG-LZ)hydrogels for wound closure after surgical eye surgeries.PEG-LZ hydrogels have plenty of micropores and gradually decreased pore size with increasing concentration from 10%,15%to 20%(w/v),in which PEG-LZ(15%)represents the suitable pH value,gelation time and elastic modulus.PEG-LZ hydrogels have no in vitro cytotoxicity and excellent ex vivo wound closure effectiveness in porcine eyes.The in vivo wound sealant in rabbit eyes by PEG-LZ hydrogels presents a superior therapeutic effect compared with the conventional methods of stromal hydration and suture,in terms of the wound closure percent,mean corneal thickness,percent of wound gaping,and the Descemet membrane detachment.PEG-LZ hydrogels do not induce obvious histological pathology changes.The PEG-LZ corneal adhesive is considered as a tissue adhesive alternative for wound closure after surgical eye surgeries.
