Assessment of Biomechanical Properties for Corneal Post Refractive Surgery [PDF]
arXiv, 2022 A stable shape for corneas experiencing refractive surgery has to be sustained so as to elude post-refractive surgery de-compensation. This de-compensation leads to visual complications and unsatisfactory procedure recovery. Variation in corneal lamellae and collagen fibres is induced by recent LASER refractive surgical procedures utilizing LASER ...

Evaluation of transplant benefits with the U.S. Scientific Registry of Transplant Recipients by semiparametric regression of mean residual life [PDF]
arXiv, 2023 Kidney transplantation is the most effective renal replacement therapy for end stage renal disease patients. With the severe shortage of kidney supplies and for the clinical effectiveness of transplantation, patient's life expectancy post transplantation is used to prioritize patients for transplantation; however, severe comorbidity conditions and old ...

On the Automated Detection of Corneal Edema with Second Harmonic Generation Microscopy and Deep Learning [PDF]
arXiv, 2022 When the cornea becomes hydrated above its physiologic level it begins to significantly scatter light, loosing transparency and thus impairing eyesight. This condition, known as corneal edema, can be associated with different causes, such as corneal scarring, corneal infection, corneal inflammation, and others, making it difficult to diagnose and ...

FEBS Open Bio, EarlyView.This study reports the upregulation of ELMO1 and GPR141 in human Fuchs' endothelial corneal dystrophy (FECD) corneal endothelium and ultraviolet A‐induced FECD mice model. A genetic association of an intergenic single nucleotide polymorphism rs918980 present between both genes is observed with FECD in the Indian population.

Deep Learning Based Unsupervised and Semi-supervised Classification for Keratoconus [PDF]
arXiv, 2020 The transparent cornea is the window of the eye, facilitating the entry of light rays and controlling focusing the movement of the light within the eye. The cornea is critical, contributing to 75% of the refractive power of the eye. Keratoconus is a progressive and multifactorial corneal degenerative disease affecting 1 in 2000 individuals worldwide ...
