Abstract

|

Purpose: To evaluate the effect of coronavirus disease 2019 (COVID-19) vaccination on the eyes.
Methods: Thirty-six healthcare providers (mean age, 32.86±8.35 years) were included. Refractive error, phoria, accommodation, intraocular pressure, pupil size, corneal thickness, and axial length were measured at 1 day, 1 week, 2 weeks, and 3 weeks after COVID-19 vaccination, and compared with measurements before vaccination.
Results: After vaccination, 4 out of 36 (11.11%) participants complained of decreased accommodation, and 3 out of 36 (8.33%) complained of blurred vision. There was no relationship between vaccination and other ocular components. Accommodation decreased from 1 day after inoculation and showed a tendency to gradually recover from 2 weeks after inoculation.
Conclusions: Approximately 10% of the subjects complained of discomfort in near vision due to a temporary decrease in accommodation after vaccination. Optometrists should be aware that some individuals may experience sudden near vision impairment due to temporary accommodative disorders following vaccination. Education and public awareness of these possible vaccine side effects are needed. A common portal system to record cases of ocular side effects after vaccination and for continuous patient monitoring may assist with the accurate diagnosis and appropriate prescription in the case of refraction in the clinic.
