Effect of corneal light scatter on vision: a review of the literature [PDF]

open access: yes, 2016
The cornea is the transparent connective tissue window at the front of the eye. The physiological role of the cornea is to conduct external light into the eye, focus it, together with the lens, onto the retina, and to provide rigidity to the entire ...

Simultaneously imaging and quantifying in vivo mechanical properties of crystalline lens and cornea using optical coherence elastography with acoustic radiation force excitation

open access: yesAPL Photonics, 2019
The crystalline lens and cornea comprise the eye’s optical system for focusing light in human vision. The changes in biomechanical properties of the lens and cornea are closely associated with common diseases, including presbyopia and cataract. Currently,

Surfactant protein D contributes to ocular defense against Pseudomonas aeruginosa in a murine model of dry eye disease. [PDF]

open access: yes, 2013
Dry eye disease can cause ocular surface inflammation that disrupts the corneal epithelial barrier. While dry eye patients are known to have an increased risk of corneal infection, it is not known whether there is a direct causal relationship between ...

Limbal stem cell transplantation: clinical results, limits, and perspectives [PDF]

open access: yes, 2018
Limbal stem cell deficiency (LSCD) is a clinical condition characterized by damage of cornea limbal stem cells, which results in an impairment of corneal epithelium turnover and in an invasion of the cornea by the conjunctival epithelium.
