| Popis: | Importance Determine phacoemulsification cataract surgery risk in a Covid‐19 era. Background SARS‐CoV‐2 (Covid‐19) transmission via microdroplet and aerosol generating procedures present a risk to medical professionals. As the most common elective surgical procedure performed globally; determining contamination risk from phacoemulsification cataract surgery may guide personal protection equipment use. Design Pilot study involving phacoemulsification cataract surgery on enucleated porcine eyes by experienced ophthalmologists in an ophthalmic operating theatre. Participants Two ophthalmic surgical teams. Methods Standardised phacoemulsification of porcine eyes by two ophthalmologists accompanied by an assistant. Fluorescein incorporated into phacoemulsification irrigation fluid identifying microdroplets and spatter. Contamination documented using a single‐lens reflex camera with a 532 nm narrow bandpass (fluorescein) filter, in‐conjunction with a wide‐field blue light and flat horizontal laser beam (wavelength 532 nm). Quantitative image analysis using Image‐J software. Main Outcome Measures Microdroplet and spatter contamination from cataract phacoemulsification. Results With phacoemulsification instruments fully within the eye, spatter contamination was limited to 16 cm below the neckline in surgeon 1 and > 5.5 cm below the neckline of surgeon 2. A small tear in the phacoemulsification irrigation sleeve, presented a worse‐case scenario the greatest spatter. No contamination above the surgeons' neckline nor contamination of assistant occurred. Conclusions and Relevance Cataract phacoemulsification generates microdroplets and spatter. Until further studies on SARS‐CoV‐2 transmission via microdroplets or aerosolisation of ocular fluid are reported, this pilot study only supports standard personal protective equipment. |
