ABSTRACT

Cataract surgery is a safe, effective and common elective procedure in Australia but access is inequitable. True waiting times for cataract care are undisclosed or inconsistently reported by governments. Estimates of true waiting times range from 4 to 30 months and have been extended during the coronavirus disease 2019 (COVID-19) pandemic. Comparative analysis revealed that reducing waiting periods from 12 to 3 months would result in estimated public health system cost savings of $6.6 million by preventing 50 679 falls. Investment in public cataract services to address current unmet needs would prevent avoidable vision impairment and associated negative consequences.

ABSTRACT

OBJECTIVE: To evaluate the standards of practice of Brazilian cataract surgeons in relation to the protective measures adopted to mitigate the risks of transmission of COVID-19 during cataract surgery, in asymptomatic patients. METHODS: A descriptive, cross-sectional, quantitative paradigm study, developed from a self-administered electronic questionnaire sent to ophthalmologists and residents/specialists in ophthalmology in Brazil, who performed cataract surgeries in 2019 and 2020, connected through social media and mail listing from local societies. RESULTS: Of the 303 participating surgeons, 159 (n=52.2%) performed elective cataract surgeries between March 20th, 2020 to June 1st, 2020. Among the measures adopted by ophthalmologists with the purpose of preventing viral transmission, the patient's temperature was measured by 84.3% (n=134), and the verification of respiratory symptoms and contact/exposure to cases of COVID-19 by 87.4% (n=139). Most did not submit their patients to laboratory tests to detect COVID-19 (145; 91.2%). In surgery, 44.7% (n=71) used an N95 mask, and 69.2% (n=110) kept their patients with a mask. No stage of phacoemulsification was modified in 144 (90.6%) participants, 13 (8.2%) added methylcellulose under the main incision, and two (1.3%), modified another surgical stage. CONCLUSION: The COVID-19 pandemic significantly interrupted part of cataract surgeries in Brazil from March to June 2020 and measures to prevent viral spread are being heterogeneously adopted by surgeons. Understanding these measures could be the first step to improve strategies to return to pre-pandemic levels.

ABSTRACT

Cataract surgery is a highly cost-effective treatment, but the surgical intervention rate in New Zealand ranks poorly compared with other high-income countries. The combination of a growing and ageing population, lost operating time due to the COVID-19 pandemic, and geographical disparities, is driving up an unmet demand for cataract surgery. We present several evidence-based strategies with overlapping benefits in access, equity, efficiency and sustainability. Key strategies include that Health New Zealand mandate a national prioritisation threshold for surgical access, and that PHARMAC leverage cheaper access to surgical supplies using nationally agreed equipment standards, establishing high-throughput cataract units, offering same day bilateral cataract surgery when appropriate, and rationalising post-operative care.

ABSTRACT

Purpose: To analyze the reasons for delay in cataract surgery in patients with advanced cataracts during the COVID-19 pandemic. Methods: This was a prospective, cross-sectional, multicenter questionnaire study which included patients with mature cataract, nuclear sclerotic cataract grade IV, and cataracts with best corrected visual acuity (BCVA) <5/60, during the COVID-19 pandemic from December 2020 to April 2021. Reasons for delay in presentation to the hospital were analyzed. Results: One thousand four hundred seventy two patients were recruited with advanced cataracts. Absence of ophthalmic care nearby (44.2%), lack of awareness regarding elective surgeries (42.6%), lack of public transportation (37%), fear of contracting COVID-19 (23.4%), and waiting for outreach camps (20.4%) were found to be the reasons behind the delay in cataract surgery. 53.7% of the patients had worsening of defective vision and 55.3% of them had difficulty in carrying out activities of family living. 30.8% of the patients faced difficulty in commuting and 8.4% of the patients suffered a fall during this pandemic due to worsening of the visual acuity. Conclusion: The lockdown imposed during the pandemic has created a significant backlog of patients who are progressing to advanced cataracts due to lack of ophthalmic care nearby, lack of awareness regarding elective surgeries, lack of public transportation, and no outreach camps. Proactive measures to deal with this backlog are of utmost need to prevent blindness due to cataract.

ABSTRACT

BACKGROUND: The delivery of cataract surgery during the COVID-19 pandemic is challenging because of the risk of nosocomial SARS-CoV-2 infection when patients attend hospital for elective care. In order to ascertain the risk to patients awaiting cataract surgery, this study aimed to identify the presence of systemic comorbidities that are associated with a high risk of severe disease or death due to COVID-19. METHODS: A prospective study of 315 patients (630 eyes) was conducted from 3rd June to 31st July 2020. An electronic health record was used to identify any systemic comorbidities that would render a patient 'clinically extremely vulnerable' to COVID-19, as outlined by the Department of Health for Northern Ireland. Patient demographics, best-corrected visual acuity (VA) and risk of postoperative anisometropia were also recorded. RESULTS: The median age of patients awaiting cataract surgery was 76 years (range 22-97). Of the 315 patients, 72% were aged over 70 and 16% were aged over 85. A systemic comorbidity that would confer high risk status was identified in 21% of patients. This high risk status was attributable to severe respiratory disease, cancer, and immunosuppression therapies in the majority of cases. The high risk group were younger than those deemed non-high risk, but there were no significant differences with respect to gender, anticipated degree of surgical difficulty, VA, or whether the patient was undergoing first or second eye surgery. Of those patients awaiting first eye cataract surgery, the mean VA in the listed eye was 0.84 logMAR and 39% (70/179) had a VA <0.3 logMAR (6/12 Snellen acuity) in their fellow eye. 57% of patients were awaiting first eye surgery, and 32% of those patients would be at risk of symptomatic anisometropia postoperatively. CONCLUSION: One-fifth of patients awaiting cataract surgery were found to be at high risk of severe disease or death from COVID-19 and these patients may experience delays in their surgical care. Additional planning is required in order to minimise the morbidity associated with delayed cataract surgery.

ABSTRACT

The aim of this study was to determine the effect of Coronavirus disease 2019 (COVID-19) pandemic on ophthalmic outpatient numbers and ophthalmic diagnosis distribution in a community hospital (Taipei City Hospital Zhongxiao Branch) in Taiwan. The COVID-19 pandemic period in Taiwan was defined as May 1 to July 31, 2021. Demographic data, including age, gender, and top 10 diagnoses from ophthalmic outpatients during this period, were collected. A corresponding control group from the same time in 2020 was also collected. The distribution of different diagnoses was analyzed, and the data of 10 most prominent diagnoses with decreased percentage of case numbers during the COVID-19 pandemic period were obtained. The number of cases during the COVID-19 pandemic decreased by 46.9% compared to the control group. The top three most common diagnoses were dry eye syndrome, glaucoma, and macular diseases. The 10 most prominent diagnoses with decreased number of cases during the COVID-19 pandemic were cataract, refraction & accommodation, macular degeneration, conjunctivitis, retinal detachment, vitreous body disorders, ophthalmic complications of diabetes mellitus, glaucoma, dry eye, and retinal vein occlusion. Identifying and treating these patients as scheduled may yield the highest cost-benefit effect in preventing visual loss during the COVID-19 pandemic.

ABSTRACT

Purpose: To study the changing trends in the morphology of cataracts at a tertiary eye care center in South India due to COVID-19 pandemic-related national lockdown. Methods: A retrospective study conducted at a tertiary eye care center in Andhra Pradesh state of South India, which included 1724 patients (1753 eyes) who underwent cataract surgery at our center during April 2019-July 2019 (1298 eyes of 1271 patients) and April 2020-July 2020 (455 eyes of 453 patients). Factors studied included preoperative lens status, associated phacodonesis or subluxation, pupil size, other eye lens status, associated retinal problems, glaucoma, and complications during surgery. Postoperative uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), corneal clarity, intraocular pressure (IOP), and disc status at postoperative day 1, 1 week, and 1-month visits were compared. Results: A significantly lower proportion of nuclear sclerosis (decreased from 83.2% in last year before lockdown to 55.2% during lockdown) and significantly higher proportions of mature, brown, or black cataract and phacomorphic, phacolytic, or Morgagnian cataract (increased from 15.5% in last year before lockdown to 43.8% during lockdown) were observed. The proportion of small-incision cataract surgery decreased significantly (from 63.2% to 57.4%), whereas the proportion of phacoemulsification increased significantly (from 35.9% to 41.5%) during lockdown as compared to last year. A significantly higher proportion of eyes with small pupils and association with retinal pathology were also observed during the lockdown. Conclusion: During the national lockdown, there was a shift from nuclear sclerosis grade toward mature, brown, black grade of cataracts. In addition, the proportion of small-incision cataract surgery decreased significantly whereas the proportion of phacoemulsification increased significantly during the lockdown. More number of cataracts with small pupils and associated retinal pathology were observed during the lockdown.

ABSTRACT

PURPOSE: To analyze the impact of the pandemic on trends in cataract surgical volume in 2020 in a high-volume tertiary care academic center in North India. METHODS: The monthly cataract surgical volume for a large, high-volume, tertiary care academic center in North India was obtained from January 2018 through December 2020. Based on historical trends, we used time-series forecasting, probability sensitivity analysis, and linear regression models to estimate what the expected monthly cataract volume should have been from March 2020 onward. RESULTS: In 2020, we expected to perform 7500 cases (assuming historical trends) but performed only 2500 cases (33% of the expected volume). The remaining 5000 cases (67% cases) constituted the "fixed" backlog. Assuming the ramp-up in cataract surgical volume starts in January 2021, results of the Monte Carlo simulation revealed that for our system, it would take on average 5 months (May 2021) under the optimistic scenario and 10 months (October 2021) under the ambivalent scenario to reach pre-pandemic expected surgical volume. There would be a collective backlog of 5500 cases under the optimistic scenario (8.8 months' worth of cases) and a collective backlog of 6900 cases under the ambivalent scenario (11 months' worth of cases). CONCLUSION: An intuitive approach and out-of-the-box solutions are required by the government and private institutes' collaborative efforts to help mitigate the disruptions caused by the pandemic and lessen the backlog without causing provider burnout.

ABSTRACT

Purpose: To describe the impact of lockdown and unlock phases of the COVID-19 pandemic on cataract surgery at a multitier ophthalmology network. Methods: This cross-sectional hospital-based study included 106,279 eyes operated between March 23, 2019 and March 31, 2021. The data of patients who underwent cataract surgery presenting during the lockdown and unlock phases were compared with the respective periods in the previous year before COVID-19. Results: The cataract surgeries performed decreased to 5.6% (839/14,994) of pre-COVID-19 volumes during the lockdown phase. There was a gradual recovery of the cataract surgeries performed to 86.7% of pre-COVID-19 volumes by May 2020 and exceeded by 17.9% by September 2020. There was a decrease in the number of women who underwent cataract surgery during the lockdown phase (49.11%) compared to the pre-COVID-19 (52.59%) or unlock phase (52.29%, P < 0.001). Patients operated during the lockdown phase were younger when compared to other groups (P < 0.001). The mean LogMAR presenting visual acuity at the time of surgery was worse in patients operated during the lockdown phase (1.84 ± 1.16) as compared to pre-COVID-19 (1.39 ± 1.05) and unlock phases (1.51 ± 1.08, P =<0.001). The proportion of patients with total cataracts were higher during the lockdown and unlock phases compared to the pre-COVID-19 phase (P < 0.001). Conclusion: The first year of the COVID-19 pandemic saw a drastic reduction in the surgical volume in the lockdown phase, which recovered quickly during the unlock period. Patients of younger age, male gender, poor presenting visual acuity, denser cataracts, and living close to the surgical center were able to access surgical care due to lockdown restrictions.

ABSTRACT

The aim of this study was to assess the effect of three waves of the COVID-19 pandemic on the number of elective cataract surgeries. A retrospective single-center consecutive case series study was performed. We included all 12,464 patients who received cataract surgery in the period between 1 January 2016 and 31 May 2021. Monthly numbers of cataract surgeries during the pandemic were compared with monthly numbers in the reference years 2016-2019. In the pandemic the number of cataract surgeries decreased by 53.4%. The monthly numbers during the first, second and third wave of the pandemic were 77.5%, 51.5% and 29.7% lower, respectively, compared with the reference level. No rebound effect was observed once the pandemic restrictions were eased. Simultaneous bilateral cataract surgeries (SBCS) constituted 6.5% of cataract procedures performed in April and May 2021 compared with 0.77% carried out between May 2019 and March 2021. While the pandemic-affected monthly numbers of cataract surgeries tend to increase recently, they are still below the prepandemic level. Patients should be encouraged to weigh the risks of COVID-19-related morbidity and mortality against the benefits of cataract surgery. Reorganization of the logistics of cataract services is advisable with consideration of SBCS as one of the options.

ABSTRACT

OBJECTIVES: Cataract surgeons may periodically take time away from operating which can lead to skills fade. There is a paucity of research investigating the experiences of returning cataract surgeons and how different individual circumstances impact on their return. Our aim was to investigate the subjective experiences of UK ophthalmologists simultaneously returning to surgery following the nationwide elective surgical hiatus due to the Covid-19 pandemic. METHODS: An online survey was nationally distributed between 01/09/2020 and 29/10/2020 to registered UK ophthalmologists. Participants indicating a surgical hiatus of 8 weeks or more were included. RESULTS: 232 of 264 responses were analysed. Covid-19 was the most frequent reason for a surgical hiatus (median 15 weeks). Perceived operating difficulties were found in 29.1%. Transient anxiety (51.7%), reduced confidence, and perceived increased surgical time were commonplace. Trainees and females were more likely to encounter negative experiences (p < 0.001) and barriers to resource accessibility. Eyesi® and online videos were the most available and accessed pre-return resources. Childcare was five times more likely to present as a barrier to resource access for females than males. CONCLUSIONS: Technical skills fade such as capsulorhexis difficulties were commonly perceived by trainee surgeons in addition to transient anxiety, reported in more than half of all surgeons following a hiatus as short as 8 weeks. Eyesi® simulation offers the potential to negate technical de-skilling. Few had formal return plans or awareness of RCOphth guidance. We believe there is scope for more specialised and targeted support for future returning cataract surgeons thereby optimising patient care.

ABSTRACT

PURPOSE: To discuss the impact of COVID-19 pandemic on the pediatric cataract surgery services in a tertiary care institute in India, as well as the protocol followed for these surgeries. METHODS: COVID-19 has hampered outpatient and elective services and surgeries throughout the world. During the national lockdown imposed in March in India, outpatient services were suspended in our institute, leading to a tremendous backlog of pediatric patients with cataract. Since the delay in surgery in pediatric cataract can cause amblyopia, our institute had resumed pediatric cataract surgeries in June 2020 at the time of Unlock-1 in the country. RESULTS: We have discussed the percentage of reduction in pediatric cataract surgeries in 2020 during the Unlock 1, 2, 3, and 4, as compared to the number of surgeries done by the pediatric ophthalmology unit in the same months last year. We had introduced triage and telemedicine in our department. We have discussed the preoperative, intraoperative, and postoperative protocol followed in our institute for children with pediatric cataract, and also the measures which can be taken for the safety of patients and staff. CONCLUSION: It is essential to ensure COVID-19 protocol, i.e., wearing a mask, social distancing, and frequent hand hygiene, among the patients and health care personnel. Redesigning pediatric cataract surgery practices is essential to ensure the safety of the health care workers and the patients.

ABSTRACT

CLINICAL RELEVANCE: In the last months, the whole world is dealing with an unprecedented public health crisis due to COVID-19 outbreak. Consequently, many governments have implemented lockdowns on a national level, affecting, among others, ophthalmic surgical practice in a globe scale. BACKGROUND: The aim of this study is to evaluate the impact of surgical theatre lockdown due to COVID-19 pandemic on the surgical performance of cataract surgeons. METHODS: Intraoperative complications and surgical time of the first 160 cataract surgeries performed by eight consultants (20 cases each) after a two-month lockdown were recorded and analysed in a cross-sectional study. The results were plotted against the last 30 cases of each surgeon before the implementation of the lockdown (240 cases). Cataract surgeons were asked to rate their subjective perspective and difficulties faced after re-opening through a questionnaire. RESULTS: The average duration of all surgeries after the lockdown was 19.1 ± 6.2 minutes showing a 14% increase compared to the one before the lockdown (16.8 ± 5.1 minutes, p = 0.0001). The complications rate was 2.09% (5/240 cases) before the abstention and 3.12% (5/160 cases) after the abstention not yielding any statistically significant difference (p = 0.74). When complicated surgeries were excluded from the analysis, surgical time was still higher after the lockdown (18.9 ± 5.9 minutes) than before (16.6 ± 5.0 minutes, p < 0.0001). 37.5% of consultants (3/8) stated that the two-month abstention from cataract surgeries has affected their surgical skills somewhat or a lot, while 62.5% (5/8) reported being more careful in their first cases after the lockdown. Most complications occurred in the hands of one surgeon who stated to be very anxious upon restart. CONCLUSION: The operating theatres' lockdown due to COVID-19 pandemic did not seem to affect the intraoperative complications rate in cataract surgery. A slight increase of surgical duration was noted, while most surgeons reported being more careful upon restart.

ABSTRACT

BACKGROUND: The COVID-19 pandemic halted non-emergency surgery across Scotland. Measures to mitigate the risks of transmitting COVID-19 are creating significant challenges to restarting all surgical services safely. We describe the development of a risk stratification tool to prioritise patients for cataract surgery taking account both specific risk factors for poor outcome from COVID-19 infection as well as surgical 'need'. In addition we report the demographics and comorbidities of patients on our waiting list. METHODS: A prospective case review of electronic records was performed. A risk stratification tool was developed based on review of available literature on systemic risk factors for poor outcome from COVID-19 infection as well as a surgical 'need' score. Scores derived from the tool were used to generate 6 risk profile groups to allow prioritised allocation of surgery. RESULTS: There were 744 patients awaiting cataract surgery of which 66 (8.9 %) patients were 'shielding'. One hundred and thirty-two (19.5 %) patients had no systemic comorbidities, 218 (32.1 %) patients had 1 relevant systemic comorbidity and 316 (46.5 %) patients had 2 or more comorbidities. Five hundred and ninety patients (88.7 %) did not have significant ocular comorbidities. Using the risk stratification tool, 171 (23 %) patients were allocated in the highest 3 priority stages. Given an aging cohort with associated increase in number of systemic comorbidities, the majority of patients were in the lower priority stages 4 to 6. CONCLUSIONS: COVID-19 has created an urgent challenge to deal safely with cataract surgery waiting lists. This has driven the need for a prompt and pragmatic change to the way we assess risks and benefits of a previously regarded as low-risk intervention. This is further complicated by the majority of patients awaiting cataract surgery being elderly with comorbidities and at higher risk of mortality related to COVID-19. We present a pragmatic method of risk stratifying patients on waiting lists, blending an evidence-based objective assessment of risk and patient need combined with an element of shared decision-making. This has facilitated safe and successful restarting of our cataract service.

ABSTRACT

IMPORTANCE: Determine phacoemulsification cataract surgery risk in a Covid-19 era. BACKGROUND: SARS-CoV-2 (Covid-19) transmission via microdroplet and aerosol-generating procedures presents 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: Standardized 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 <10 cm. Insertion and removal of the phacoemulsification needle and bimanual irrigation/aspiration, with irrigation active generated spatter on the surgeons' gloves and gown extending 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.
