Purpose: To evaluate the germicidal efficacy of the SaniteyesTM ultraviolet-C (UVC) high-level disinfection system for multi-use ophthalmic equipment such as eyedropper bottles, tonometer tips, and diagnostic and laser lenses.
Design: Evaluation of technology.
Participants: Not applicable.
Methods: Disinfection efficacy was assessed using both carrier and simulated use tests against multiple bacterial, viral, and fungal microorganisms. Organisms were selected based on commonly accepted indicators for disinfection efficacy and/or ophthalmic relevance. Stainless steel carriers, eyedropper nozzles, applanation prisms, ophthalmic lenses, and other instruments were inoculated before being placed within a disinfection bay of the SaniteyesTM system. After pre-cleaning and disinfection, the log reduction in viable organisms was measured. Tests were performed according to American Society of Testing and Materials (ASTM) International Standards for high-level disinfection (HLD). All tests were performed with negative controls, soiled controls, and three replicates for efficacy studies.
Main outcome measures: Log reduction in viable organisms following disinfection.
Results: All carrier (n=42) and simulated use tests (n=24) showed reduction by more than 6-log for all bacteria and fungi, and by more than 4-log for viruses, in accordance with efficacy cutoffs for HLD.
Conclusions: The SaniteyesTM automated disinfection system offers fast and chemical-free HLD of multi-use ophthalmic devices to meet regulatory standards of the CDC, FDA, and Joint Commission.
An initial insult to an infant's developing brain can set off a chain reaction. This singular, damaging CNS event can cause subsequent injuries to the extrastriate cortex, which manifest later in childhood.
