Mask wear did not result in statistically significant mean changes in keratometry readings on topography and tomography. However, axis of astigmatism varied >10 degrees in the majority of patients. Axis determination should be interpreted with caution with respect to refractive surgery and/or toric intraocular lens planning in individuals whose measurements were obtained while wearing a mask.
