Association between non-invasive tear film breakup time and corneal higher-order aberrations in eyes with tear film instability

Background. Dry eye disease (DED) is associated with higher-order aberrations (HOAs), which are increasingly recognized as affecting both ocular comfort and visual acuity. Tear film instability reduces the regularity of the corneal surface between blinks, causing increased light scatter and reduced optical quality, eve...
