To study the prevalence of coronavirus infection among asymptomatic patients requiring eye surgery and the role of screening in prevention of spread of infection among the healthcare workers.
The prospective observational study was conducted in the Ophthalmology department of a tertiary care center in Delhi from September 2020 to December 2020.
Patients requiring elective ophthalmological procedures in a tertiary care hospital were screened for coronavirus using the RT-PCR method. Testing methods and results were documented.
Among the 218 asymptomatic patients posted for elective surgery in that period, 16 (7.3%) were found to be positive for COVID-19. Those who tested positive were advised home isolation and surgery was postponed for the next 14 days. No complications were reported in these patients. One health-care worker also tested positive for COVID-19 during our study period.
In our study, 1 out of 14 asymptomatic patients were found to be carriers for the novel virus. Asymptomatic COVID-infected patients may lead to transmission of the virus inside the hospital among the visiting patients and hospital staff while they have no adverse effect on the surgery and its outcome.
研究需要进行眼科手术的无症状患者中冠状病毒感染的患病率，以及筛查在预防医护人员中感染传播的作用。
前瞻性观察性研究于2020年9月至2020年12月在德里一家三级医疗中心的眼科进行。
在一家三级医院中，对需要进行择期眼科手术的患者使用逆转录聚合酶链反应（RT-PCR）方法进行冠状病毒筛查。记录检测方法和结果。
在该时期安排进行择期手术的218例无症状患者中，16例（7.3%）新冠病毒检测呈阳性。检测呈阳性的患者被建议居家隔离，手术推迟14天。这些患者未报告并发症。在我们的研究期间，一名医护人员新冠病毒检测也呈阳性。
在我们的研究中，每14例无症状患者中有1例被发现是新型病毒携带者。无症状的新冠病毒感染患者可能会在医院内导致病毒在就诊患者和医院工作人员之间传播，而他们对手术及其结果没有不良影响。
