A new approach for the in-vivo characterization of the biomechanical behavior of the breast and the cornea

Lago Ángel, Miguel Ángel (Universitat Politècnica de València, 2014-11-13)

The characterization of the mechanical behavior of soft living tissues is a big challenge in Biomechanics. The difficulty arises from both the access to the tissues and the manipulation in order to know their physical ...
A new methodology for the in vivo estimation of the elastic constants that characterize the patient-specific biomechanical behavior of the human cornea

Lago, M. A.; Rupérez Moreno, María José; Martínez Martínez, Francisco; Monserrat Aranda, Carlos; Larra, E.; Gueell, J. L.; Peris-Martinez, C. (Elsevier, 2015-01)

This work presents a methodology for the in vivo characterization of the complete biomechanical behavior of the human cornea of each patient. Specifically, the elastic constants of a hyperelastic, second-order Ogden model ...
A refined model on flow and oxygen consumption in the human cornea depending on the oxygen tension at the interface cornea_post lens tear film during contact lens wear

Compañ Moreno, Vicente; Aguilella-Arzo, Marcel; del Castillo, Roxana M.; Espinos Gutierrez, Francisco Juan; del Castillo, Luis Felipe (Elsevier, 2022-04-27)

[EN] The study of oxygen consumption rate under¿ in vivo¿ human cornea during contact lens wear has been technically a challenge and several attempts have been made in the last 20 years to model the physiology of the human ...
Analysis of the application of the Generalized Monod kinetics model to describe the Human Corneal Oxygen-Consumption Rate During Soft Contact Lens Wear

Compañ Moreno, Vicente; Aguilella-Arzo, M.; Del Castillo, L.F.; Hernández, S.I.; Gonzalez-Meijome, J.M. (John Wiley & Sons, 2016)

[EN] This work is an analysis of the application of the generalized Monod kinetics model describing human corneal oxygen consumption during soft contact lens wear to models previously used by Chhabra et al. (J Biomed Mater ...
Applicator for RF Thermokeratoplasty: Feasibility Study Using Theoretical Modeling and Ex Vivo Experiments

Trujillo Guillen, Macarena; Ribera, Vicente; Quesada, Rita; Berjano, Enrique (Springer Verlag (Germany), 2012)

Radiofrequency (RF) thermokeratoplasty uses RF currents to alter the curvature of the cornea by means of thermal lesions. An RF applicator which combined a microkeratome suction ring and a circular electrode was designed ...
Biointegration of corneal macroporous membranes based on poly(ethyl acrylate) copolymers in an experimental animal model

Alió del Barrio, Jorge L.; Chiesa, Massimo; Gallego-Ferrer, Gloria; Garagorri, Nerea; Briz, Nerea; Fernández Delgado, Jorge; Sancho-Tello Valls, María; Carda Botella, Carmen; García-Tuñón, Ignacio; Bataille, Laurent; Rodríguez, Alejandra; Arnalich Montiel, Francisco; Gómez Ribelles, José Luís; Antolinos Turpín, Carmen María; Gómez Tejedor, José Antonio (Wiley: 12 months, 2015-03)

Currently available keratoprosthesis models (nonbiological corneal substitutes) have a less than 75% graft survival rate at 2 years. We aimed at developing a model for keratoprosthesis based on the use of poly(ethyl acrylate) ...
Corneal Equilibrium Flux as a Function of Corneal Surface Oxygen Tension

Compañ Moreno, Vicente; Aguilella-Arzo, Marcel; Weissman, Barry A. (Lippincott Williams & Wilkins, 2017)

[EN] Purpose Oxygen is essential for aerobic mammalian cell physiology. Oxygen tension (PO2) should reach a minimum at some position within the corneal stroma, and oxygen flux should be zero, by definition, at this point ...
Diffractive corneal inlay for presbyopia

Furlan, Walter D.; Garcia-Delpech, Salvador; Udaondo, Patricia; Remón Martín, Laura; Ferrando Martín, Vicente; Monsoriu Serra, Juan Antonio (John Wiley & Sons, 2017)

[EN] A conceptually new type of corneal inlays for a customized treatment of presbyopia is presented. The diffractive inlay consists on a small aperture disc having an array of micro-holes distributed inside the open zones ...
Evolution of the critical oxygen tension

Chang, Annie; Compañ Moreno, Vicente; Weissman, Barry A. (PentaVision Media, 2018)
Patient-specific simulation of the intrastromal ring segment implantation in corneas with keratoconus

Lago, M. A.; Rupérez Moreno, María José; Monserrat Aranda, Carlos; Martínez Martínez, Francisco; Martinez-Sanchis, Sandra; Larra, Eva; Díez-Ajenjo, M. A.; Peris-Martínez, C. (Elsevier, 2015-11)

Purpose The purpose of this study was the simulation of the implantation of intrastromal corneal-ring segments for patients with keratoconus. The aim of the study was the prediction of the corneal curvature recovery ...
Ring electrode for radio-frequency heating of the cornea: modelling and in vitro experiments

Berjano, Enrique; Saiz Rodríguez, Francisco Javier; Alió, J.; Ferrero, J. M. (Springer-Verlag, 2003-11)

[EN] Radio-frequency thermokeratoplasty (RF-TKP) is a technique used to reshape the cornea curvature by means of thermal lesions using radio-frequency currents. This curvature change allows refractive disorders such as ...
