Ophthalmology practice during COVID-19 pandemic: A survey of Indian ophthalmologists

Purpose:To assess the ophthalmic practice pattern among ophthalmologists in India amidst the COVID-19 pandemic.Methods:An online questionnaire-based analysis was performed among members of the All India Ophthalmological Society (AIOS) and results were analyzed using SPSS software version 20.Results:A total of 2253 responses were received. The majority of the participants (72.6%) were between 30 and 60 years of age and were into private practice (64.7%). During the lockdown, over one-third of participant ophthalmologists reported not attending any OPD patients, whereas a majority (64%) provided only emergency ophthalmic services. During the COVID-19 pandemic, <15% surgeries were performed compared to the pre-COVID-19 era by 81% of participants, whereas elective surgeries were performed by only 4.3%. The proportion of participants utilizing telemedicine in ophthalmology showed a two-fold rise from the pre-COVID-19 era (21.9%) to the COVID-19 pandemic (46%). Over half of the participants reported following the AIOS guidelines, reducing clinic hours, use of screening questionnaires, minimizing staff, and use of breath shield on a slit lamp as precautionary measures to reduce the exposure. Over 95% of ophthalmologists were satisfied (score > 5/10) by the AIOS guidelines for ophthalmic practice during COVID-19.Conclusion:COVID-19 pandemic has adversely affected the ophthalmic care services across India with telemedicine emerging as a major rescue. The majority of practicing ophthalmologists are satisfied with guidelines provided by AIOS for ophthalmic care during the COVID-19 pandemic and have implemented the same in their setup.     

Pediatric cataract surgery practices in the COVID-19 era: Perspectives of a tertiary care institute in Northern India

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.     

Point-of-care rapid antigen testing for COVID-19 at a tertiary eye care facility: Role in commencement of elective surgeries,contact tracing and implementation of back-to-work policy

Purpose:The aim of this study was to report the use and the impact of a point-of-care rapid antigen test (PoC-RAT) at a tertiary eye care facility in facilitating commencement of elective surgeries, contact tracing of exposed health care professionals (HCPs) and ancillary hospital staff, and implementation of back-to-work (BTW) policy for them.Methods:Retrospective analysis of subjects undergoing PoC-RAT for COVID-19 infection at a tertiary level dedicated eye care facility. Decision making with regard to commencement of elective surgeries post COVID-19 related discontinuation of services, contact tracing of HCPs and ancillary hospital staff exposed to known COVID-19 cases and implementation of back-to-work policy for all staff based upon the results of PoC-RAT were studied.Results:A total of 311 subjects (224 patients and 87 hospital staff) were tested. Overall positivity rate was around 7%. Asymptomatic patients who were screened preoperatively had a lower positivity rate at around 3% compared to the staff (who were either known contacts or were symptomatic) at around 17%. Contact tracing found three-quarters of the staff at low risk and only one quarter at medium or high risk. Among patients, 97% of those followed up for at least 2 weeks after the test remained healthy. For staff, this was around 65%.Conclusion:Based on our preliminary results, we suggest that PoC-RAT may be considered routinely for indication-based preoperative screening of asymptomatic patients, and for on-campus screening, contact tracing and implementation of BTW policies for HCPs and ancillary hospital staff at a tertiary level eye care facility.     

The impact of COVID-19 “Unlock-I” on L V Prasad Eye Institute Network in Southern India

Purpose:The aim of this study was to report on the impact of COVID-19 “Unlock-I” on Network of Eye Centers in Southern India.Methods:Our eye health pyramid model has a network of eye care centers in four Indian states. The network constitutes a center of excellence (CoE) at the apex followed by tertiary care centers (TC) located in urban areas, secondary care centers (SC), and primary care vision centers (VC) at the base located in rural areas. We collected data on patients seen between June 2019 and June 2020, which included age, gender, total patients seen (new or follow-up), and socioeconomic status (paying and nonpaying). A comparative study was done between the data for outpatients and surgeries performed pre-COVID-19 and during Unlock-I in COVID-19 period.Results:There was a 36.71% reduction in the overall outpatients seen in June 2020 (n = 83,161) compared to June 2019 (n = 131,395). The reduction was variable across different levels of the pyramid with the highest reduction in CoE (54.18%), followed by TCs (40.37%), SCs (30.49%) and VCs (18.85%). Similar pattern was seen for new paying patients with the highest reduction in CoE (54.22%), followed by TCs (25.86%) and SCs (4.9%). A 43.67% reduction was noted in the surgeries performed in June 2020 (n = 6,168), compared to June 2019 (n = 10,950). Reduction in paying services was highest in CoE (47.52%), followed by TCs (15.17%) and SCs (4.87%). There was no significant change in the uptake of services by gender in the network.Conclusion:Highest reduction in patient footfalls during “Unlock-1” was noted in urban centers. Going forward, there is a need to develop strategies to provide eye care closer to the doorsteps.     

Year one of COVID-19 pandemic in India: Effect of lockdown and unlock on trends in keratoplasty at a tertiary eye centre

Purpose:To describe the impact of lockdown and unlock phases of the COVID-19 pandemic on keratoplasty trends at a tertiary eye care center in India.Methods:This cross-sectional hospital-based study included 6,277 patients presenting between March 25, 2017 and March 31, 2021. The data of the patients who underwent keratoplasty during the lockdown and unlock phases were compared with the respective periods in the previous three years before COVID-19.Results:During the year one of pandemic, there was a 29.46% decline in the total number of keratoplasty performed at the institute compared to previous year’s annual numbers. The patients undergoing keratoplasty decreased by 90.28% (28/288) of pre-COVID-19 volumes during the lockdown phase. This was mainly because of a 40.6% reduction in the proportion of patients requiring interstate travel. There was complete recovery in the number of patients undergoing keratoplasty to 129.27% (184/142) of pre-COVID-19 volumes by March 2021. This gradual incremental trend was seen across all types of keratoplasty in Descemet stripping endothelial keratoplasty (135.29%), penetrating keratoplasty (117.6%), therapeutic keratoplasty (122.22%), anterior lamellar keratoplasty (150%), and Descemet membrane endothelial keratoplasty (141.18%) by March 2021 with the gradual ease of lockdown regulations. The eye bank affiliated to the institute saw a 55.44% decline in donor cornea collection and an increase in utilization rate from 58.12% in previous years to 83.78% in year one of the pandemic. The overall eye bank donor cornea collection recovered to 86.96% (627/721) and tissue utilization increased by 109.99% (455/414) by March 2021.Conclusion:The first year of the COVID-19 pandemic saw an overall reduction of 29.46% of the patients undergoing keratoplasty at the institute. There was a gradual and incremental increase in all types of keratoplasty in the unlock phase, which surpassed the preceding years’ monthly numbers in February and March.

An online survey questionnaire was completed by ophthalmology residents from different parts of the country. The survey consisted of questions related to the impact of the pandemic on training, innovative training techniques adapted during the pandemic and their effectiveness, and COVID-19 duty-related information.Results:A total of 147 responses were obtained. The mean age was 29.3 years (range: 24–40 years, SD: ±3.82). Of which, 87 (59.2%) respondents were females. A total of 61 (41.5%) respondents reported practicing steps of ocular surgeries on goat eye, 69 (46.9%) on model eye/vegetables/fruits, 30 (20.4%) on surgical simulators, and 26 (17.7%) utilized 3-D virtual images and videos. In addition, 22 (15%) respondents reported never using any such techniques. Furthermore, 130 (88.4%) respondents reported practicing steps of cataract surgery, 52 (35.4%) practiced steps of open globe repair, and steps of trabeculectomy were reported by 24 (16.3%). The steps that were reported to be practiced most are incision or tunnel construction by 108 (73.5%), suturing by 92 (62.6%), capsulorrhexis by 91 (61.9%), primary wound repair by 82 (55.8%), and conjunctival peritomy by 75 (51%).Conclusion:The present study demonstrates that residents across the country are adapting to the present scenario by utilizing several innovative methods to sharpen their surgical acumen. The current pandemic situation can serve as an impetus to emphasize upon the institutes and medical regulatory bodies to appropriately remodel the residency curriculum.     

Managing vitreoretinal surgeries during COVID-19 lockdown in India: Experiences and future implications

Purpose:The study aims to describe the clinical and demographic profile of patients who required vitreoretinal surgeries during the novel coronavirus disease-2019 (COVID-19) lockdown in India. It also reports our operating protocols and initial experience while performing vitreoretinal surgeries during COVID-19 times at a government tertiary eye care hospital.Methods:This is a retrospective cross-sectional observational study of patients requiring emergent/urgent vitreoretinal surgeries between March 25, 2020 and May 31, 2020. A modified working protocol focussing on the enforcement of standard COVID-19 precautions, OT sterilization, and formation of dedicated infection control and disease surveillance committee was adopted. Patients underwent standard vitreoretinal procedures under general/local anesthesia. Relevant demographic and clinical data were recorded and analyzed. Surveillance data of healthcare workers (HCW) was also analyzed.Results:Eighty six patients were considered for vitreoretinal surgery in this period. Finally, 83 patients underwent surgery. The mean age of the patients was 38.4 ± 20.1 years (Range, 1 month - 75 years). Majority of them were males (66%) and adults (82.6%). Majority of them came from nearby hotspot areas. Most common indications were acute retinal detachment (38.5%) and diabetic vitrectomies (22.9%). Trauma-related cases (14.4%) were less. Surgery was deferred in 3 patients who turned out to be COVID-19 positive. 4 HCWs were quarantined but none of them developed COVID-19 disease.Conclusion:During COVID-19 lockdown, vitreoretinal surgeries were most commonly performed for retinal detachment and diabetic complications. Proper implementation of infection control protocols helps in delivering adequate patient care while ensuring the safety of caregivers during this pandemic.     

Reworking protocols of ophthalmic resident surgical training in the COVID-19 era – Experiences of a tertiary care institute in northern India

Purpose:Coronavirus Disease 2019 (COVID-19) pandemic has negatively impacted medical professionals in all fields of medicine and surgery in their academic, clinical and surgical training. The impact of surgical training has been described as ‘severe’ by most ophthalmology residents worldwide due to their duties in COVID-19 wards, disruption of outpatient and camp services.Methods:Ophthalmic surgery demands utmost accuracy and meticulousness. Fine motor proficiencies, stereoscopic skills and hand–eye coordination required can only be achieved by practice. So, a multileveled structured wet-lab teaching schedule was prepared for the residents and implemented to bridge this gap between theory and practice at our tertiary care institute. A semester-wise training schedule was made with the proper distribution of wet-lab and simulator training. Surgeries like phacoemulsification, scleral buckling, pars plana lensectomy and vitrectomy, trabeculectomy and intravitreal injections were practised by the residents on the goat eyes. Simulator training was provided for phacoemulsification and vitrectomy to increase the hand–eye coordination of the residents.Results:Residents noticed improvement in their surgical skills and ambidexterity post wet-lab and simulator training . It also increased their confidence and provided essential surgical skills required to be used in the operation theater later.Conclusion:It is imperative that wet-lab training be included in the residency training programme in this COVID-19 era.     

Preoperative COVID-19 testing for elective vitreoretinal surgeries: Experience from a major tertiary care institute in South India

Purpose:To study the prevalence of asymptomatic SARS-CoV-2 virus infection (COVID-19) among patients undergoing elective vitreoretinal surgeries at a tertiary care eye hospital.Methods:This cross-sectional, observational study was performed between July 16, 2020 and August 31, 2020, in the retina clinic of a tertiary care eye hospital in south India. All patients undergoing elective retinal surgical procedures underwent RT-PCR testing for SARS-CoV-2 before being posted for surgery and after obtaining informed consent. Patients planned for surgery under general anesthesia underwent additional computed tomography of the chest. Testing strategies and outcomes were documented.Results:Out of a total of 413 patients who were given appointments for surgery during this period, nine patients (2.2%) were found to have positive RT-PCR for SARS-CoV-2, and their surgeries were postponed. The test positivity (prevalence) rate of asymptomatic COVID-19 infection among all elective vitreoretinal surgical patients in our hospital was 2.2%. None of the patients were symptomatic for COVID-19.Conclusion:Our results showed that among patients visiting high volume ophthalmic centers in the near future, approximately 1 in 45 patients may be asymptomatic, SARS-CoV-2 RT-PCR positive. Asymptomatic COVID-19 patients may lead to chances of transmission of the virus inside healthcare facilities among other visiting patients and healthcare workers.     

Impact of COVID-19 on follow-up and medication adherence in patients with glaucoma in a tertiary eye care centre in south India

Purpose:COVID-19 pandemic has affected the healthcare system worldwide hindering the continuum of treatment of chronic disease patients. The objective of the study is to analyze the barriers encountered by the glaucoma patients for the follow-up visit and medication adherence during the pandemic.Methods:This cross-sectional study included glaucoma patients who did not attend the scheduled appointment from April 1, 2020 to July 31, 2020 in a tertiary eye care center (88.21%). Eligible patients of age >18 years and advised antiglaucoma medication in Madurai Zone were interviewed with validated questionnaire through telephonic call.Results:363 patients answered the questionnaire through telephonic interview. 57.3% of the patients were found to be non-adherent to medication. The main barriers for glaucoma follow-up visit during the pandemic were lockdown restriction, transport problem, and financial difficulties. The top barriers for medication adherence were non availability of medication (54.81%), financial difficulties (30.29%), did not feel much improvement with eye drops (20.19%). On multiple regression analysis, longer distance to hospital, low socioeconomic status, more than one antiglaucoma medication use, lack of awareness of glaucoma, non-complaint before COVID-19 and stress due to the pandemic were found to be significant factors for medication non adherence.Conclusion:COVID-19 pandemic has emphasized the need for reformation in health care system for accessibility of medical care to patients in rural areas. Decentralization of health system to primary care level and utilization of teleophthalmology should be considered by health care planners in future.     

Tele-rehabilitation for visually challenged students during COVID-19 pandemic: Lesson learned

Purpose:The COVID-19 outbreak poses a global crisis in health care delivery system, including habilitation and rehabilitation services. In this study, we shared our experiences on telerehabilitation services established primarily for students with visual disabilities (SwVD) amidst COVID-19 pandemic and its outputs.Methods:Following the lockdown declared on March 23, 2020, the rehabilitative team of a tertiary eye center in north India received information that many visually challenged students (VCS) were stranded in schools for the blind in Delhi, and feeling with anxiety and panic in absence of teachers. Shortly, the room for vision rehabilitation clinic was set-up for telefacilities. The intended services were explained while disseminating the mobile numbers. A semi-structured questionnaire consisting of closed and open-ended was developed to record COVID-19 knowledge and concerns. Inductive content analysis was used to report the qualitative information.Results:As of June 30, 2020, a total of 492 clients contacted the team, with maximum from Delhi (41.5%), and predominantly males (78.8%). Around 80.3% of callers were VCS with age range of 11 to 30 years. The two most frequently encountered health needs were itching in eyes (36.1%) and headache (29%). Television news was the most used medium among callers to get COVID-19 information. Cough is a less frequently known mode of transmission (28%), similarly handwashing as a less known for prevention (17.2%). Eight concerns were recorded based on qualitative data analysis.Conclusion:Telerehabilitation provides valuable insights and has the potential to address various concerns, uncertainty, anxiety, and fear among VCS during the pandemic.     

Reasons for delay in cataract surgery in patients with advanced cataracts during the COVID-19 pandemic

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.
