Los ojos son sin embargo unos órganos especialmente delicados, de manera que la aplicación de elementos accesorios sobre ellos requiere una adaptación minuciosa de dichos elementos y además que éstos resulten compatibles en cada caso; mientras que en las intervenciones quirúrgicas es necesaria una precisión muy meticulosa, dependiendo también de los medios y elementos que se utilizan.The eyes are however organs especially delicate, so that the application of elements accessories on them requires a thorough adaptation of said elements and also that these are compatible in each case; while in surgical interventions a very meticulous precision, also depending on the means and elements that are used.
Para las correcciones de los ojos es fundamental por lo tanto disponer de unos medios y elementos que se adapten con precisión al ojo de aplicación y que sean fáciles de aplicar en la forma que se halle prevista para su función.For eye corrections it is essential therefore have some means and elements that adapt precisely to the eye of application and make them easy to apply in the form that is planned for its function.
De acuerdo con la invención se propone una lentilla destinada para implantación intracorneal, la cual se ha desarrollado con unas características constructivas y funcionales que la hacen muy ventajosa para la aplicación correctora de la presbicia aislada o asociada a otros defectos de refracción, como miopía, hipermetropía y astigmatismo.According to the invention, a lens intended for intracorneal implantation, which has been developed with constructive and functional characteristics which make it very advantageous for the corrective application of the presbyopia isolated or associated with other refractive defects, such as myopia, farsightedness and astigmatism.
Esta lentilla objeto de la invención se constituye por un cuerpo anular, construido de un material hidrogel de alta porosidad (macropore), yendo dotado con una graduación progresiva de corrección óptica.This lens object of the invention is constitutes by an annular body, constructed of a hydrogel material high porosity (macropore), going endowed with a graduation progressive optical correction.
Se obtiene así una lentilla para implante intracorneal, mediante realización de un alojamiento en el lecho estromal, para el alojamiento de la lentilla y su cubrimiento con la capa corneal correspondiente a dicho alojamiento.An implant lens is thus obtained intracorneal, by making a bed accommodation stromal, for housing the lens and its covering with the corneal layer corresponding to said housing.
La realización de la lentilla en su forma se determina con un diámetro interior y un diámetro exterior, pudiendo establecerse un perfecto ajuste personalizado de la lentilla, lo cual favorece un mejor resultado de la función de la misma.The realization of the lens in its form is determined with an inner diameter and an outer diameter, being able to Set a perfect custom lens adjustment, what which favors a better result of its function.
El material constructivo de esta lentilla la hace además perfectamente compatible con el tejido estromal del ojo, pero no obstante su aplicación resulta reversible, de forma que puede ser retirada del ojo levantando la capa corneal que cubre a la lentilla en la implantación, lo cual permite también sustituir la lentilla cuando así lo aconseje el desarrollo del defecto ocular para el que se halla aplicada.The construction material of this lens the It also makes it perfectly compatible with the stromal tissue of the eye, but nevertheless its application is reversible, so which can be removed from the eye by lifting the corneal layer that covers to the lens in the implantation, which also allows replacing the lens when advised to develop the defect eyepiece for which it is applied.
Por todo ello, dicha lentilla objeto de la invención resulta de unas características ciertamente ventajosas, adquiriendo vida propia y carácter preferente para la función correctora de los defectos oculares frente a los elementos y técnicas convencionales de esta aplicación.For all this, said lens object of the invention results from certainly advantageous features, acquiring own life and preferential character for the function corrective eye defects against the elements and Conventional techniques of this application.
La figura 1 muestra la forma de una lentilla según el objeto de la invención.Figure 1 shows the shape of a lens according to the object of the invention.
El objeto de la invención se refiere a una lentilla destinada para ser aplicada en implantación intracorneal, poseyendo unas características que la hacen ventajosa para corregir la presbicia sola o con otros defectos asociados, como la miopía, la hipermetropía y el astigmatismo.The object of the invention relates to a contact lens intended for intracorneal implantation, possessing characteristics that make it advantageous to correct presbyopia alone or with other associated defects, such as myopia, farsightedness and astigmatism.
Esta lentilla, se constituye por un cuerpo (1) de forma anular, realizado de un material hidrogel de alta porosidad (macropore) que presenta una alta permeabilidad, resultando perfectamente biocompatible con el tejido estromal del ojo para la implantación.This lens is constituted by a body (1) annular shape, made of a high hydrogel material porosity (macropore) that has high permeability, resulting perfectly biocompatible with the stromal tissue of the eye for implantation.
En su realización formal dicho cuerpo (1) de la lentilla se determina con un contorno interior (2) y un contorno exterior (3) definidos con radios (R2) y (R3), de forma que en la aplicación el implante de la lentilla resulta con un ajuste personalizado al ojo, que hace muy efectiva la función de la misma.In its formal realization said body (1) of the contact lens is determined with an inner contour (2) and an outline exterior (3) defined with radii (R2) and (R3), so that in the application the lens implant results with an adjustment personalized to the eye, which makes the function of the same.
Dicho cuerpo (1) de la lentilla se estructura además con un graduación óptica progresiva, resultando de una utilidad funcional para corregir la presbicia y otros defectos oculares que ésta lleve asociados, como la miopía, la hipermetropía y el astigmatismo, con un efectividad muy elevada.Said body (1) of the lens is structured also with a progressive optical graduation, resulting from a functional utility to correct presbyopia and other defects eyepieces associated with it, such as myopia, farsightedness and astigmatism, with a very high effectiveness.
La implantación de la lentilla se realiza efectuando unos cortes en la superficie corneal del ojo de aplicación, según el contorno interior y el contorno exterior del iris de la lentilla preparada al respecto, realizándose dichos cortes mediante técnica láser, de femtosegundo.The implantation of the lens is done making cuts in the corneal surface of the eye of application, according to the inner contour and the outer contour of the Lens iris prepared in this regard, making said laser cuts, femtosecond.
En la ablación realizada se coloca la lentilla preparada para la implantación, secándose la zona para asegurar la fijación de la lentilla, y después se repone la capa superficial de la cornea, con la cual se cubre la lentilla, volviéndose a secar la zona para asegurar la fijación de dicha capa superficial de cubrimiento.In the performed ablation the lens is placed prepared for implantation, drying the area to ensure the lens fixation, and then the surface layer of the cornea, with which the lens is covered, re-drying the area to ensure the fixation of said surface layer of covering.
La técnica de la implantación y la naturaleza de la lentilla que se preconiza, permiten que después de implantada la lentilla ésta pueda ser retirada mediante una operación sencilla, cuando el portador lo desee, para volver al estado inicial, levantando la capa superficial de la cornea que cubre la lentilla y extrayendo ésta, para volver a reponer luego la capa superficial de la cornea en su lugar, donde mediante un secado de la zona se asegura la fijación y estabilidad de dicha capa superficial.The implantation technique and the nature of the lens that is recommended, allow after implantation the lens can be removed by an operation simple, when the carrier wishes, to return to the state initial, lifting the superficial layer of the cornea that covers the contact lens and removing this one, to replace the layer again superficial cornea in place, where by drying the area ensures the fixation and stability of said layer superficial.
Mediante la extracción de la lentilla implantada y posterior incorporación de una nueva lentilla en su lugar, se puede igualmente corregir de manera progresiva, mediante diferentes lentillas, los defectos del ojo en su evolución, a medida que se van desarrollando en las personas.By removing the implanted lens and subsequent incorporation of a new lens in its place, it it can also correct progressively, through different contact lenses, eye defects in their evolution, as they leave developing in people.
