Evaluation of acute corneal damage induced by 222-nm and 254-nm ultraviolet light in Sprague-Dawley rats

Abstract

Two hundred twenty-two nanometres ultraviolet (UV) light produced by a krypton-chlorine excimer lamp is harmful to bacterial cells but not skin. However, the effects of 222-nm UV light exposure to the eye are not fully known. We evaluated acute corneal damage induced by 222-nm and 254-nm UV light in albino rats. Under deep anaesthesia, 6-week-old Sprague-Dawley albino rats were exposed to UV light. The exposure levels of corneal radiation were 30, 150, and 600 mJ/cm2. Epithelial defects were detected by staining with fluorescein. Superficial punctate keratitis developed in corneas exposed to more than 150 mJ/cm2 of UV light, and erosion was observed in corneas exposed to 600 mJ/cm2 of UV light. Haematoxylin and eosin staining also showed corneal epithelial defects in eyes exposed to 254-nm UV light. However, no damage developed in corneas exposed to 222-nm UV light. Cyclobutane pyrimidine dimer-positive cells were observed only in normal corneas and those exposed to 254-nm UV light.

Although some epithelial cells were stained weakly in normal corneas, squamous epithelial cells were stained moderately, and the epithelial layer that was detached from the cornea exposed to 600 mJ/cm² of light was stained intensely in corneas exposed to 254-nm UV light. In the current study, no corneal damage was induced by 222-nm UV light, which suggested that 222-nm UV light(222 UVC light flat module far UVC light lamp downlight module) may not harm rat eyes within the energy range and may be useful for sterilising or preventing infection in the future.

The pursue of the business, is definitely the clients' gratification for 222nm UVC Lamp for Hospital Far UVC LED Commercial Tube UV Multi-Functional Sterilizer .... We follow our enterprise spirit of 'Quality, Efficiency, Innovation and Integrity'. We have an excellent work team constantly developing new products and learning from international brands to provide customers with better services and more cost-effective products.
