Imaging shear stress distribution and evaluating the stress concentration factor of the human eye
Open accessAbstract
Healthy eyes are vital for a better quality of human life. Historically, for man-made materials, scientists and engineers use stress concentration factors to characterise the effects of structural non-homogeneities on their mechanical strength. However, such information is scarce for the human eye. Here we present the shear stress distribution profiles of a healthy human cornea surface in vivo using photo-stress analysis tomography, which is a non-intrusive and non-X-ray based method. The corneal birefringent retardation measured here is comparable to that of previous studies. Using this, we derive eye stress concentration factors and the directional alignment of major principal stress on the surface of the cornea. Similar to thermometers being used for monitoring the general health in humans, this report provides a foundation to characterise the shear stress carrying capacity of the cornea and a potential bench mark for validating theoretical modelling of stresses in the human eye in future.

The arrangement of these putative structures seems to correspond with the shear stress distribution in the peripheral cornea.
“The arrangement of these putative structures seem to correspond with the sheer stress distribution in the peripheral cornea (Antony, 2015).”

The Results and Discussion report that the measured shear-stress profile correlates with the diamond-like structural architecture of the cornea. The paper describes this correlation for the cornea generally, not specifically for the peripheral cornea, so the location in the citing sentence is not established by our copy. (LLM, conf=0.82)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
