Purpose: This study aimed to investigate changes in visual function after the first and second shots with the COVID- 19 vaccine.
Methods: In 114 eyes of 57 patients (30 males, 27 females with mean age of 38.18±9.56 years) that could be followed up after the COVID-19 vaccination, 1 day, 1 week, 2 weeks, and 3 weeks after the first and second shots, the corrective refractive power, accommodative amplitude, and phoria were measured and compared with before vaccination.
Results: The change in corrected refractive power after vaccination showed a statistically significant difference after vaccination with AstraZeneca and Pfizer with the first shot (p<0.001, p=0.030). After the second shot, only the heterologous vaccination showed a statistically significant difference (p<0.001). The change in accommodative amplitude showed a statistically significant difference in all periods regardless of the type of vaccine (p<0.001) and a greater change in the second shot period than in the first shot period. The change of phoria showed a statistically significant difference in both the far and near after the first shot (p=0.025, p=0.015).There was no significant difference after the second shot.
Conclusions: After vaccination, the decrease in accommodative amplitude was remarkable. The second shot showed a greater decrease in accommodative amplitude than during the first shot period. After vaccination, corrected refractive power and phoria did not have a statistically significant difference or clinically meaningful changes.
