RESUMEN
The SARS-CoV2 pandemic has created extreme shortages of N95 mask necessitating the need for rapid development of reuse and reprocessing plans. Our aim was to create a process to recapture, reprocess, and redistribute N95 masks using hydrogen peroxide vapor as a real time disinfection method within a large hospital system. We were able to recapture and reprocess 29, 706 N95 masks using hydrogen peroxide vapor with approximately 25% loss due to damage.

A 59-year-old pseudophakic woman with a history of Prosed/DS use demonstrated a discolored Tecnis Z9001 (AMO) silicone intraocular lens (IOL). Polymethyl methacrylate (PMMA), hydrophobic acrylic, silicone, and Collamer IOLs were submerged in a physiologic concentration of methylene blue at 35 degrees C for 8 weeks and evaluated. No staining was noted in PMMA or hydrophobic acrylic IOLs, variable staining was noted in silicone IOLs, and intense staining was noted in Collamer IOLs. This is the first report of IOL staining with systemic use of methylene blue and of Collamer lens staining characteristics.
