While ATP bioluminescence testing is accepted for evaluating the cleanliness of surgical instruments, the borescope\u2019s ability to facilitate a visual inspection of the internal integrity of phaco handpiece lumens remains underreported. This study aims to evaluate the efficacy of current cleaning protocols and explore the borescope\u2019s utility in visually inspecting phaco handpieces. In this analysis, 41 phaco handpieces underwent borescope examination and ATP bioluminescence testing following thorough cleaning, with two inspections completed on each handpiece. Borescope inspections revealed that 56.10% of phaco handpieces harbored foreign materials or exhibited various forms of structural damage, such as corrosion, rust, green lint, and discoloration. However, ATP bioluminescence testing deemed the cleanliness of all handpieces satisfactory. This study demonstrates the value of a borescope in the visual inspection of phaco handpieces, revealing issues such as corrosion and rust that necessitated immediate flushing of the lumen with sterile distilled or deionized water. The detection of green lint led to the prohibition of placing textile fiber-containing sterile textile wipes on the operating table surface by sterile supply staff, enhancing patient safety measures. Future efforts will focus on addressing the challenges posed by corrosion and particulate formation during rinsing.<\/jats:p>","DOI":"10.1371\/journal.pone.0323327","type":"journal-article","created":{"date-parts":[[2025,5,8]],"date-time":"2025-05-08T13:33:13Z","timestamp":1746711193000},"page":"e0323327","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":3,"title":["The
