A validated model for correcting Confounding Factors in Corneal Densitometry

Confounding factors (brightness, ACD, CCT, tilt) introduce systematic bias in corneal densitometry measurements. A validated correction model, developed with synthetic data (n=1000) and validated clinically (n=132), enables accurate isolation of age ...

Birefringent properties of the human cornea in vivo : towards a new model of corneal structure [PDF]

The fundamental corneal properties of mechanical rigidity, maintenance of curvature and optical transparency result from the specific organisation of collagen fibrils in the corneal stroma. The exact arrangement of stromal collagen is currently unknown
