Abstract
The Coronavirus (COVID-19) outbreak is rapidly emerging as a global health threat. With no proven vaccination or treatment, infection control measures are paramount. In this article, we aim to describe the impact of COVID-19 on our practice and share our strategies and guidelines to maintain a sustainable ophthalmology practice.
Tan Tock Seng Hospital (TTSH) Eye Centre is the only ophthalmology department supporting the National Centre for Infectious Diseases (NCID), which is the national screening center and the main center for management of COVID-19 patients in Singapore. Our guidelines during this outbreak are discussed.
Challenges in different care settings in our ophthalmology practice have been identified and analyzed with practical solutions and guidelines implemented in anticipation of these challenges. First, to minimize cross-infection of COVID-19, stringent infection control measures were set up. These include personal protective equipment (PPE) for healthcare workers and routine cleaning of “high-touch” surfaces. Second, for outpatient care, a stringent dual screening and triaging process were carried out to identify high-risk patients, with proper isolation for such patients. Administrative measures to lower patient attendance and reschedule appointments were carried out. Third, inpatient and outpatient care were separated to minimize interactions. Last but not least, logistics and manpower plans were drawn up in anticipation of resource demands and measures to improve the mental well-being of staff were implemented.
We hope our measures during this COVID-19 pandemic can help ophthalmologists globally and serve to guide and maintain safe access in ophthalmology clinics when faced with similar disease outbreaks.

With its basic reproduction number close to or higher than SARS-CoV [<xref ref-type="bibr" rid="CR3">3</xref>, <xref ref-type="bibr" rid="CR4">4</xref>] and MERS-CoV [<xref ref-type="bibr" rid="CR5">5</xref>], COVID-19 represents a potentially higher pandemic risk than the SARS outbreak in 2003 [<xref ref-type="bibr" rid="CR6">6</xref>]. Initial cases of zoonotic transmission from bats [<xref ref-type="bibr" rid="CR7">7</xref>] have since evolved into human-to-human transmission through droplets, fomites [<xref ref-type="bibr" rid="CR8">8</xref>], fecal material [<xref ref-type="bibr" rid="CR9">9</xref>], and tears [<xref ref-type="bibr" rid="CR10">10</xref>]. Detection of SARS-CoV-2 in tears and conjunctival secretions of infected patients with conjunctivitis [<xref ref-type="bibr" rid="CR10">10</xref>], similar to findings during the 2003 SARS outbreak [<xref ref-type="bibr" rid="CR11">11</xref>], suggests a unique risk to the ophthalmology department.</p><p id="Par6">Clinical progression of COVID-19 seems similar to that of SARS, with majority of cases (80%) having mild to moderate disease after an incubation period of 5–6 days (range, 1–14 days). Common symptoms include fever (87.9%), dry cough (67.7%), and fatigue (38.1%) [<xref ref-type="bibr" rid="CR12">12</xref>]. Of note, 0.8% of patients presented with conjunctival congestion [<xref ref-type="bibr" rid="CR12">12</xref>], presenting new challenges to ophthalmologists. Interestingly, the first medical professional to sound the alarm on a possible outbreak was a late Chinese ophthalmologist from Wuhan, Hubei, China [<xref ref-type="bibr" rid="CR13">13</xref>].</p><p id="Par7">Singapore reported our first imported case on 23 January 2020. We have since enforced strict border control through travel advisories and entry restrictions from high-risk countries like China and South Korea raised our “Disease Outbreak Response System Condition” (DORSCON) level from yellow to orange and implemented measures to minimize community spread through cancelation or deferment of large-scale events, daily health checks at workplaces, and restricting doctors from travelling between different healthcare institutions [<xref ref-type="bibr" rid="CR14">14</xref>].</p><p id="Par8">As of 26 March 2020, there were 462,684 confirmed cases and 20,834 deaths globally, with 81,961 of the confirmed cases and 3293 of the deaths occurring in China [<xref ref-type="bibr" rid="CR15">15</xref>]. One hundred and ninety-nine countries and territories have been affected [<xref ref-type="bibr" rid="CR15">15</xref>], with numbers continuing to climb. Singapore has had a total of 683 COVID-19 cases, with 172 discharged and 2 fatalities [<xref ref-type="bibr" rid="CR16">16</xref>]. High incidence rates were also seen in Italy (74,386 cases), USA (63,570 cases), Spain (47,610 cases), Germany (36,508 cases), and Iran (27,017 cases) [<xref ref-type="bibr" rid="CR15">15</xref>].</p><p id="Par9">Being the only ophthalmology department supporting the National Centre for Infectious Diseases (NCID), the national screening center and the main center for management of COVID-19 patients in Singapore, we would like to discuss the impact COVID-19 has had on our practice, detail our past experiences with infection control in ophthalmology, and apply these concepts to develop a sustainable practice of ophthalmology at Tan Tock Seng Hospital (TTSH) Eye Centre. We hope to serve as a model to guide future management in ophthalmology clinics when faced with the current and similar disease outbreaks.</p></sec><sec id="Sec2"><title>Challenges affecting ophthalmic practice</title><sec id="Sec3"><title>Infection control</title><p id="Par10">TTSH Eye Centre is one of the busiest outpatient clinics in TTSH. With a usual patient load of 600 patients per day, the risk of COVID-19 transmission is imminent and catastrophic. Furthermore, ophthalmology is a unique practice requiring routine use of reusable equipment in close contact with patients and with many high-risk high-touch surfaces [<xref ref-type="bibr" rid="CR17">17</xref>], thereby increasing the risk of disease transmission among ophthalmology patients. Examples include the Goldmann applanation tonometer (GAT) heads, slit lamp, contact lenses, eye drops, chin-rests, and table surfaces of ophthalmic diagnostic and laser devices such as the Humphrey visual field and optical coherence tomography. This, coupled with the fact that Coronaviruses can survive up to 96 h in biological fluids and in high relative humidity and low temperature [<xref ref-type="bibr" rid="CR18">18</xref>], thus makes contaminated surfaces key sources of iatrogenic transmission of infections [<xref ref-type="bibr" rid="CR19">19</xref>–<xref ref-type="bibr" rid="CR22">22</xref>] between patients [<xref ref-type="bibr" rid="CR11">11</xref>, <xref ref-type="bibr" rid="CR23">23</xref>].</p></sec><sec id="Sec4"><title>Outpatient care</title><p id="Par11">During this COVID-19 outbreak, our department’s weekly outpatient visits’ no-show rate has increased significantly from 13 to 33%. Possible reasons include patients postponing follow-up visits to avoid hospitals, or departments postponing visits to keep outpatient attendance low to reduce risks of cross-infection [<xref ref-type="bibr" rid="CR24">24</xref>]. Uncertainty in the duration of the outbreak [<xref ref-type="bibr" rid="CR25">25</xref>] makes choosing a new appointment date difficult. Hence, patients who miss appointments, especially glaucoma patients, are predisposed to sight-threatening complications [<xref ref-type="bibr" rid="CR26">26</xref>].</p></sec><sec id="Sec5"><title>Inpatient care</title><p id="Par12">The TTSH ophthalmology department only accepts inpatient referrals from NCID or TTSH general wards. Movement of inpatients and ophthalmologists to and from different wards and the eye center poses significant means of cross-infection between different wards, as well as between outpatient and inpatient services.</p></sec><sec id="Sec6"><title>Surgery</title><p id="Par13">In ophthalmology, surgical turnover and caseload are high, with a daily average of 40 to 50 ambulatory day surgeries at the TTSH Eye Centre. Hence, surgical procedures serve as a means for cross-infection between surgical patients from different wards, as well as between patients and healthcare workers from different departments.</p></sec><sec id="Sec7"><title>Healthcare worker</title><p id="Par14">As SARS-CoV-2 can cause conjunctivitis [<xref ref-type="bibr" rid="CR27">27</xref>, <xref ref-type="bibr" rid="CR28">28</xref>], precautions should be taken against transmission through aerosol contact with the conjunctiva. Moreover, patients may be infectious even before symptom manifestation [<xref ref-type="bibr" rid="CR29">29</xref>]. Hence, ophthalmologists are at increased risks for COVID-19 because of their proximity to a patient’s nose and mouth and potential exposure to tears which may contain the virus [<xref ref-type="bibr" rid="CR30">30</xref>]. As such, the American Academy of Ophthalmology has recommended protection for the mouth, nose, and eyes when caring for patients potentially infected with COVID-19 [<xref ref-type="bibr" rid="CR28">28</xref>].</p></sec></sec><sec id="Sec8"><title>Sustainable ophthalmic practice guidelines</title><p id="Par15">With no effective antiviral treatment available [<xref ref-type="bibr" rid="CR31">31</xref>] and an effective vaccine unlikely to be widely available for up to 6 months [<xref ref-type="bibr" rid="CR32">32</xref>], the COVID-19 outbreak continues to challenge the healthcare ecosystem. Thus, healthcare infrastructure should be directed at enhancing detection of cases and minimizing transmission risks at all frontiers.</p><p id="Par16">In addition, the added physical, mental, and social stressors to ophthalmologists from both patient and personal safety concerns should be addressed [<xref ref-type="bibr" rid="CR33">33</xref>].</p><sec id="Sec9"><title>General infection control</title><p id="Par17">Ophthalmic equipment can be contaminated with respiratory droplets, tears, and conjunctival secretions of infected patients [<xref ref-type="bibr" rid="CR10">10</xref>]. Unattended to, ophthalmic equipment may serve as hot-beds for virus contamination as patients often come in close contact with them.</p><p id="Par18">Routine cleaning significantly reduces environmental contamination [<xref ref-type="bibr" rid="CR34">34</xref>]. However appropriate cleaning agents should be used. A review of studies on antiseptics-disinfectants for human coronaviruses (HCoVs) recommended the use of a povidone-iodine or combination of chlorhexidine with ethanol and cetrimide for infection control against HCoV [<xref ref-type="bibr" rid="CR18">18</xref>]. Most alcohol-based solutions, such as isopropanol or ethanol, also significantly reduced viral titers [<xref ref-type="bibr" rid="CR35">35</xref>] and are recommended. Surprisingly, some commonly used antiseptics-disinfectants formulated with only quaternary ammonium compounds or phenolic compounds, or a combination formulation of chlorhexidine with cetrimide, were found to be ineffective against HCoV [<xref ref-type="bibr" rid="CR36">36</xref>] and thus may be ineffective against COVID-19 as well.</p><p id="Par19">Hence, we recommend that healthcare workers wash their hands with combination chlorhexidine with ethanol and cetrimide, or hand-rub with alcohol-based solutions, and routinely clean “high-touch” surfaces after each patient. To ensure proper decontamination of ophthalmic devices and optical surfaces, we suggest reviewing product inserts of each device for the most appropriate cleaning method and ensure that the recommended cleaning agent is effective in disinfecting COVID-19. In addition, we recommend avoiding the use of the air puff to measure intraocular pressure to prevent the generation of aerosols from infected conjunctival secretions that risk transmission to healthcare workers [<xref ref-type="bibr" rid="CR37">37</xref>].</p></sec></sec><sec id="Sec10"><title>Outpatient care</title><p id="Par20">Proper triaging of patients is imperative in a busy clinic to reduce the spread of possible disease and for contact tracing purposes. TTSH employs a stringent dual screening and triaging process to classify patients and all accompanying persons based on their COVID-19 status.</p><p id="Par21">Firstly, at all entry points of the hospital, their temperatures are checked by thermal image cameras, while stationed staff screen them for the following:<list list-type="order"><list-item><p id="Par22">Travel or close contact with recent travelers to affected countries (Mainland China, Republic of Korea, Japan, Iran, Northern Italy);</p></list-item><list-item><p id="Par23">Close contact with a case of COVID-19;</p></list-item><list-item><p id="Par24">Acute respiratory infection (ARI) (cough, fever, and shortness of breath).</p></list-item></list></p><p id="Par25">Those negative for all of the above are given a round triage sticker, while those with no travel or contact risk factors but have acute respiratory symptoms are given a hexagonal triage sticker. Those who are positive for all three will be denied entry and sent to the NCID screening center instead (Table <xref rid="Tab1" ref-type="table">1</xref>). To prevent the reuse of stickers, the color of the stickers is changed daily. At the electronic registration counter of the eye center, patients and accompanying persons are again screened to pick out suspected COVID-19 cases based on the criteria listed in Figs. <xref rid="Fig1" ref-type="fig">1</xref> and <xref rid="Fig2" ref-type="fig">2</xref>, in particular noting patients with acute respiratory symptoms.<table-wrap id="Tab1"><label>Table 1</label><caption><p>Questionnaire for screening of outpatients</p></caption><graphic position="anchor" xlink:href="417_2020_4682_Tab1_HTML" id="MO1"></graphic></table-wrap><fig id="Fig1"><label>Fig. 1</label><caption><p>Registration workflow for outpatients</p></caption><graphic xlink:href="417_2020_4682_Fig1_HTML" id="MO2"></graphic></fig><fig id="Fig2"><label>Fig. 2</label><caption><p>Registration workflow for accompanying persons</p></caption><graphic xlink:href="417_2020_4682_Fig2_HTML" id="MO3"></graphic></fig></p><p id="Par26">Patients and accompanying persons negative for the COVID-19 suspect criteria are given a green triage sticker. Otherwise, the attending doctor is informed about the suspect patient to assess the need for a same-day consultation. Any suspect accompanying persons will be denied entry into the clinic and informed to leave the hospital premises.</p><p id="Par27">Suspect patients in need of a same-day consult are given a surgical mask and an orange triage sticker for identification, before being escorted to the isolation “pink” room. Thereafter, the treatment room nurse will check the patient’s visual acuity as well as reassure and advise the patient on the isolation protocols. Guidelines on the clinic triage protocol (Figs. <xref rid="Fig1" ref-type="fig">1</xref> and <xref rid="Fig2" ref-type="fig">2</xref>) have been affixed within the eye center to ensure that all triage personnel and medical staff are familiar.</p><sec id="Sec11"><title>General patients</title><p id="Par28">With a stringent and robust triaging and screening system in place, most routine eye consults would thus be with patients without respiratory symptoms and at low risk for COVID-19. Current recommendations from the WHO and the Centers for Disease Control and Prevention would be personal protective equipment (PPE) according to standard precautions. In our hospital, standard precautions for all staff include surgical masks in all clinical areas, mitigating the risk of inadvertent exposure of a health care worker to an unidentified COVID-19 patient.</p><p id="Par29">In addition, since subclinical patients are capable of transmitting the virus [<xref ref-type="bibr" rid="CR29">29</xref>], to prevent and limit cross-infection, reducing outpatient attendance is important. To this end, senior ophthalmologists screen through clinical notes to determine patients with stable conditions whose appointments can be safely rescheduled, while the eye center administrative team contacts patients at least 1 week prior to their scheduled appointments to update them on their new appointments. These patients will also have their prescriptions refilled. This has resulted in a 30% reduction of the 13,000 monthly patients.</p><p id="Par30">Patients who defaulted their follow-up were also not neglected. After each subspecialty clinic, senior ophthalmologists screen through a defaulter name-list from their clinic and give an appropriate time frame for rescheduling their appointments. The administrative team will then contact patients and update them on their new appointments.</p></sec><sec id="Sec12"><title>High-risk patients</title><p id="Par31">For high-risk patients fulfilling the above criteria, full PPE is worn at all times by all involved healthcare workers, with the patient placed and examined in dedicated isolation “pink” rooms. Single-use consumables such as eye drops are used to reduce the risk of transmission to the next patient, with non-disposable equipment cleaned with appropriate disinfectants as discussed above.</p><p id="Par32">The importance and enforcement of PPE should also extend to the hospital’s janitorial service. Studies have shown the presence of SARS-CoV-2 in an infected patient’s biological products and waste [<xref ref-type="bibr" rid="CR9">9</xref>, <xref ref-type="bibr" rid="CR11">11</xref>, <xref ref-type="bibr" rid="CR12">12</xref>]. Yet, past experience from SARS suggested that cleaners in affected hospitals viewed their risk of exposure to SARS as low, at only 0.50 times that of doctors [<xref ref-type="bibr" rid="CR38">38</xref>]. This is concerning as these misconceptions from cleaners, who play an essential role in the hospital’s cleanliness and hygiene, may lead to non-compliance of infection control measures. Hence, it is imperative that new understanding and updates on COVID-19 are communicated down the entire organization.</p></sec></sec><sec id="Sec13"><title>Inpatient care</title><p id="Par33">Separating inpatient and outpatient ophthalmology care is the cornerstone of our practice to curtail the risk of cross-infection. As far as possible, inpatients should be seen at the bedside. If specific equipment or investigations only available outpatient are required, the inpatient is then seen at an outpatient clinic that has been specifically allocated for inpatient use, with minimal to no interaction with other outpatients. These cases are vetted to ensure they are non-suspect cases and afebrile. In addition, to avoid the congregation of inpatients from different wards, separate time slots have been allotted for each group—ophthalmology inpatients are seen at 8 am, while inpatient interdisciplinary referrals to ophthalmology are only seen after 9:30 am (Fig. <xref rid="Fig3" ref-type="fig">3</xref>).<fig id="Fig3"><label>Fig. 3</label><caption><p>Workflow for inpatients</p></caption><graphic xlink:href="417_2020_4682_Fig3_HTML" id="MO4"></graphic></fig></p><p id="Par34">To further minimize interaction between these different groups of patients, inpatients are under constant supervision by clinic staff, with diagnostic investigations minimized. This is in concordance with the practice in Hong Kong during the SARS outbreak, where inpatients were seen by the bedside with portable equipment, and transfer of inpatients to the outpatient department was contraindicated due to their high risk of cross-infection [<xref ref-type="bibr" rid="CR23">23</xref>].</p></sec><sec id="Sec14"><title>Surgery</title><p id="Par35">Aerosol-generating procedures such as tracheal intubation and manual ventilation before intubation increase the risk of transmission of acute respiratory infections to healthcare workers by 3 to 7 times [<xref ref-type="bibr" rid="CR37">37</xref>]. With ventilatory support required during surgery, yet posing a risk to healthcare workers, we have postponed non-emergency elective cases to reduce caseload and potential infection risks to both patients and healthcare workers alike and reinforced screening for cough and fever during our pre-operative assessment if surgery is necessary. This has reduced our ambulatory day surgeries by about 50%.</p><p id="Par36">Where surgery is needed, proper PPE is worn when intubating patients who are undergoing general anesthesia. If manipulation of the nasopharynx is involved, such as dacryocystorhinostomy, donning of appropriate PPE with the N95 mask is required for all operating theater staff.</p><p id="Par37">Protective eyewear was found to reduce transmission risk in SARS [<xref ref-type="bibr" rid="CR39">39</xref>]. We recommend the use of visor masks or coverspecs over the use of goggles, as although both increase the working distance from the operating microscope and affects visualization during surgery, the latter further impairs vision due to condensation.</p><p id="Par38">Should emergency surgery be necessitated for confirmed COVID-19 cases, the operating theater is regarded as at high-risk and universal precaution measures will be taken, with the use of goggles and N95 masks for all staff within the operating theater. Similar measures for ophthalmic surgeries were used in other institutions during outbreaks [<xref ref-type="bibr" rid="CR23">23</xref>, <xref ref-type="bibr" rid="CR40">40</xref>].</p></sec><sec id="Sec15"><title>Healthcare workers</title><sec id="Sec16"><title>Preparedness plans</title><p id="Par39">Using lessons learned from the 2003 SARS and 2009 H1N1 outbreak, Singapore has continuously expanded and upgraded its capacity to better manage emerging infectious disease outbreaks like COVID-19. Steps taken include infrastructural reform through the construction of the National Centre for Infectious Diseases (NCID) and National Public Health Laboratory and equipping all public hospitals with isolation facilities ready to accept COVID-19 patients, as opposed to centralized treatment of all SARS patients at TTSH in 2003. At an organizational level, formal platforms for collaboration have been established, with protocols ready for implementation and training provided to healthcare professionals [<xref ref-type="bibr" rid="CR33">33</xref>] as it has been shown to reduce transmission rates [<xref ref-type="bibr" rid="CR39">39</xref>].</p></sec><sec id="Sec17"><title>Logistics</title><p id="Par40">Currently, there is a high worldwide demand for PPE with many countries running low on supplies for their healthcare workers [<xref ref-type="bibr" rid="CR41">41</xref>]. At the national level, although the Singapore government has maintained a 6-month national stockpile of PPE and masks in preparation for crises since SARS in 2003 [<xref ref-type="bibr" rid="CR42">42</xref>], with available stockpiles prioritized for healthcare institutions [<xref ref-type="bibr" rid="CR43">43</xref>], clinic managers should take stock of their current supplies and devise sustainable usage strategies for staff until resupply. For example, in our clinic, each healthcare worker is allotted 2 surgical masks per day, which must be signed out from a centralized location to facilitate usage tracking, minimize wastage, and ensure proper use of resources.</p></sec><sec id="Sec18"><title>Manpower</title><p id="Par41">Additional hospital and clinic screening efforts, as detailed above, may draw staff away from their normal duties. In addition, ophthalmologists may have to augment and support departments such as the emergency department and inpatient units that are under tremendous strain from the influx of patients. Unprecedented community cluster outbreaks may lead to sudden surges of patients and place further strain on the hospital. Thus, these contingency requirements, though previously unthinkable, may require planning and forethought. To achieve this, our department has undertaken superfluous staffing to cater to the differing elasticities of manpower demand during this crisis [<xref ref-type="bibr" rid="CR44">44</xref>] by restricting all leave and conference attendances.</p></sec><sec id="Sec19"><title>Personnel protection and training</title><p id="Par42">In addition to providing PPE, refresher training on how to don and remove PPE should be provided to all healthcare staff to decrease infection risk [<xref ref-type="bibr" rid="CR39">39</xref>]. Repeat N95 mask fitting should also be carried out if done more than 1 year ago as the lack of training is associated with greater transmission risks [<xref ref-type="bibr" rid="CR39">39</xref>]. In lieu of live PPE demonstrations, online training material and videos could be circulated to avoid mass gathering of staff. Education on the rationale and importance of PPE should also be continually emphasized as the physical discomfort and time-consuming nature can lead to lapses in compliance during a long-drawn outbreak.</p><p id="Par43">To enhance the protection of all healthcare staff, updating influenza vaccination to the prevailing seasonal strain can be considered. Though the influenza vaccine confers no protection against COVID-19, it may help avoid false alarms of clusters of fevers due to circulating strains transmitting among staff, avoiding unnecessary quarantine measures [<xref ref-type="bibr" rid="CR45">45</xref>].</p></sec><sec id="Sec20"><title>Personnel communication and social distancing</title><p id="Par44">Methods to reduce workplace transmission of influenza may be adapted for COVID-19. Workplace social distancing measures have been previously studied as a means to prevent influenza transmission [<xref ref-type="bibr" rid="CR46">46</xref>]. Practical measures to reduce non-clinical work contact without affecting manpower requirements include stopping large group gatherings beyond 10 people and replacing department meetings and teachings with video conferencing. Mealtimes can also be staggered and distanced seating (2 m apart) implemented in common staff areas.</p><p id="Par45">With social distancing in place, dissemination of critical information through traditional means such as department or hospital meetings will be inefficient and be a potential source of disease spread. In a rapidly evolving or complex healthcare crisis, in addition to e-mails, communication can be supplemented with widely used smartphone messaging applications such as WhatsApp and Telegram. The benefit is that unlike short message service (SMS), which only allows single person interactions, modern messaging apps allow large group chats. This facilitates fast large group dissemination of information, consultation, coordination, and action. Many functional social-level group chats may already exist and should be tapped on, for example administrative, resident, nursing, or ophthalmic technician groups. A situational crisis group for COVID-19 may comprise key stakeholders for decision-making in a clinic or department and leaders from different functional groups. Such chats also serve as a temporary resource of relevant information, where documents and protocols can be attached. Larger organizations may even have approved secure instant messaging applications like the TigerConnect, and organizational policies may dictate that only these be used.</p></sec><sec id="Sec21"><title>Resilience and mental well-being</title><p id="Par46">The 2003 SARS outbreak taught us the significant psychosocial impact a highly infectious disease outbreak can have on hospital staff [<xref ref-type="bibr" rid="CR47">47</xref>, <xref ref-type="bibr" rid="CR48">48</xref>]. Inexperience in dealing with such an outbreak among young healthcare workers, coupled with increased workload and risk perceptions, compounds the physical and psychological stresses that healthcare workers have to deal with daily [<xref ref-type="bibr" rid="CR38">38</xref>]. Hence, the psychological welfare of staff must not be neglected. Assistance in this regard could be sought from affiliated psychiatry or psychology departments or colleagues. Staff could be taught self-help methods on coping with stress and increasing resilience. Avenues for seeking help should be made known to all staff so that those experiencing an acute stress reaction can seek help. A 3S (Staff Support Staff) framework could also be instituted where fellow staff members help look out for signs in colleagues and are trained to provide informal psychological support. These efforts should persevere beyond the resolution of COVID-19.</p><p id="Par47">Due to the uncertainty and prolonged period of stress during this COVID-19 outbreak, it is crucial to support healthcare workers through planning well-being initiatives (both within and beyond the hospital) and understanding the practical issues faced by staff [<xref ref-type="bibr" rid="CR49">49</xref>]. In this aspect, an anonymized TTSH-NCID workplace well-being survey was conducted to aid in understanding the difficulties faced by staff while at work during the COVID-19 outbreak. Other similar avenues should be explored to understand how hospital management can better support their staff during this trying period. The concept of a department or clinic welfare officer can also be considered, where he/she works toward the well-being of all staff at the behest of the department or clinic. Ground-level stresses and grievances can then be safely surfaced, and wellness activities planned and executed.</p></sec><sec id="Sec22"><title>Conclusion</title><p id="Par48">In an emergent healthcare crisis caused by COVID-19, we discuss important considerations for healthcare leaders in ophthalmology and examples of how they have been applied. The initial emphasis is certainly on rigorous infection control to ensure that healthcare workers and patients are protected. In the longer term, we also suggest that strategies be developed to conduct standard eye care and surgery safely to maintain a sustainable practice. The aim, ultimately, is to maintain public confidence and safe access to both routine and emergency eye care while balancing the additional needs in a disease outbreak.</p></sec></sec></body><back><fn-group><fn><p><bold>Publisher’s note</bold></p><p>Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.</p></fn><fn><p>Louis W.
