PURPOSE OF REVIEW: The use of nonpharmaceutical interventions can prevent viral spread in COVID-19 pandemic and PPE forms a crucial part of this strategy . However, there are discrepancies in existing guidelines and a lack of consensus among ophthalmic communities . This review aims to identify general consensus and provides recommendation of PPE for most common ophthalmological scenarios . With a global shortage of PPE, extended use and reuse strategies are also discussed .
RECENT FINDINGS: In this review, guidelines and resources were selected, based on a three-tier process . The first-tier resources were from international infection control organizations . The second-tier resources were from ophthalmological professional associations and colleges . The third-tier resources involved a PubMed search using the keywords 'COVID-19; coronavirus; personal protective equipment' performed on 1 May 2020 . Non-English guidelines and literatures were excluded .
SUMMARY: On the basis of our methodology, we included a total of 30 documents, including 5 resources from tier 1 , 14 resources from tier 2 and 15 from tier 3 . Different levels of protection are necessary . Whenever performing an aerosol generating procedure, maximum protection should be ensured, this includes FFP3 respirator, fluid resistant gown, goggles or face-shield and disposable gloves . Similar protection should be used for handling COVID-19-positive/suspected case but the use of FFP2 respirator is acceptable . During routine outpatient clinic in cases of negative triage, it is recommended to use ASTM III surgical mask, plastic apron, disposable gloves and eye protection with goggles or face-shield . Lastly, patients should be encouraged to wear surgical masks whenever possible.
