En la actualidad las técnicas existentes para determinar un color de ojos selectivo, se basan en la utilización de productos liquidos o gelatinosos de aplicación sobre los ojos, lo cual sirve solo para dotar de una ligera tonalidad de colorido a todo el ojo, sin discriminación de las partes del mismo, por lo que la efectividad es muy limitada.At present, the existing techniques for determining a selective eye color are based on the use of liquid or jelly-like products applied to the eyes, which only serves to provide a slight shade of color to the entire eye, without discrimination of the parts of it, so the effectiveness is very limited.
Una solución que permite adaptar la tonalidad de la zona coloreada correspondiente al iris del ojo, es la utilización de lentillas incorporadas de manera provisional sobre la parte frontal de los ojos, lo cual suele aplicarse de un modo restringido en el caso de los usuarios de lentillas oculares para corregir la visión, siendo un sistema que en general no se ajusta con la debida exactitud a las dimensiones del iris en los usuarios por lo que la función especifica de la coloración es deficiente.A solution that allows you to adapt the hue of the colored area corresponding to the iris of the eye, is the use of lenses temporarily incorporated on the front of the eyes, which It is usually applied in a restricted way in the case of users of eye contact lenses to correct vision, being a system that in general does not adjust with the correct accuracy to the dimensions of the iris in users so the specific function of the coloration It is lacking.
Objeto de la invenciónObject of the invention
De acuerdo con la invención se propone un sistema basado en una técnica de aplicación intraocular, mediante el cual se puede adaptar el color de los ojos de una manera efectiva y práctica, con un resultado de aspecto natural de los ojos tratados.According to the invention, a system based on a technique of intraocular application is proposed, whereby the color of the eyes can be adapted in an effective and practical manner, with a natural-looking result of the treated eyes.
Este sistema objeto de la invención consiste en la implantación de una lentilla ultrafina coloreada entre las capas corneales del ojo, incorporándose dicha lentilla en un alojamiento practicado al efecto, mediante realización de un corte corneal superficial de diámetro igual al contorno del iris del ojo y la práctica de una ablación de alojamiento de la lentilla a implantar, la cual se cubre en dicho alojamiento con la capa corneal superficial levantada de la zona del corte.This system object of the invention consists in the implantation of a colored ultra-thin lens between the corneal layers of the eye, said lens being incorporated in a housing made for the purpose, by means of a superficial corneal cut of diameter equal to the contour of the iris of the eye and the practice of a housing ablation of the lens to be implanted, which is covered in said housing with the surface corneal layer lifted from the cutting area.
Se utilizan para tal fin lentillas microporosas biocompatibles de hydrogel, de modo que resultan permeables al oxigeno, agua y nutrientes, con lo que permiten el normal metabolismo del ojo, pudiendo ser circulares o anulares, en correspondencia con el contorno del iris del ojo de aplicación y con una zona central transparente o vacia en relación con la pupila.Biocompatible hydrogel microporous contact lenses are used for this purpose, so that they are permeable to oxygen, water and nutrients, thus allowing the normal metabolism of the eye, being able to be circular or annular, in correspondence with the iris contour of the application eye and with a transparent or empty central zone in relation to the pupil.
Dichas lentillas se fabrican a medida para cada destinatario, lo que determina su perfecta adaptación a los ojos en la disposición de aplicación, pudiendo ser dotadas de manera adicional con características correctoras de problemas oculares, con lo que además de la función principalmente estética para la que se halla previsto, el sistema permite también ser aprovechado para solucionar problemas, como aniridias, deformaciones congénitas, traumáticas o quirúrgicas del iris, fotofobia esencial y por albinismo, despigmentación del iris por uveitis crónica, etc., además de conseguir una protección contra el sol y deslumbramientos .These lenses are made to measure for each recipient, which determines its perfect adaptation to the eyes in the application arrangement, and can be additionally provided with corrective characteristics of eye problems, which in addition to the mainly aesthetic function for which it is intended, the system also allows be used to solve problems, such as aniridia, congenital, traumatic or surgical deformations of the iris, essential photophobia and albinism, depigmentation of the iris due to chronic uveitis, etc., in addition to achieving protection against the sun and glare.
Y, por otro lado, el sistema resulta reversible é intercambiable, de modo que después de implantadas las lentillas coloreadas, pueden ser retiradas de un modo sencillo cuando el usuario lo desee, asi como ser sustituidas por otras, para cambiar la coloración aplicada en los ojos.And, on the other hand, the system is reversible and interchangeable, so that after the colored lenses have been implanted, they can be removed in a simple way when the user wishes, as well as being replaced by others, to change the color applied in the eyes
Por todo ello, dicho sistema de la invención resulta de unas características que le confieren vida propia y carácter preferente sobre las técnicas convencionales que se aplican para fines semejantes.Therefore, said system of the invention results from characteristics that give it its own life and preferential character over conventional techniques that are applied for similar purposes.
Descripción detallada de la invenciónDetailed description of the invention
El objeto de la invención se refiere a un sistema de tratamiento de los ojos para adaptar el color de los mismos, utilizándose una técnica de estética intraocular que resulta segura y sencilla de aplicar.The object of the invention relates to an eye treatment system to adapt the color thereof, using an intraocular aesthetic technique that is safe and simple to apply.
El sistema consiste en incorporar una lentilla coloreada ultrafina en la zona del iris del ojo, colocándose dicha lentilla en un alojamiento que se practica al respecto entre las capas corneales del ojo.The system consists of incorporating an ultra-thin colored lens in the iris area of the eye, said lens being placed in a housing that is practice about it between the corneal layers of the eye.
Para ello, en primer lugar se practica un corte corneal superficial en el ojo de aplicación, según un diámetro coincidente con el contorno del iris del ojo, realizándose dicho corte con láser de femtosegundo (Intralase) , de tal forma que se deja una pequeña zona del contorno circular sin cortar, para que sirva de bisagra a la capa superficial recortada.To do this, first, a superficial corneal cut is made in the application eye, according to a diameter coinciding with the contour of the iris of the eye, said femtosecond laser cutting (Intralase) being performed, so that a small area is left of the uncut circular contour, to serve as a hinge to the trimmed surface layer.
Una vez realizado el corte se levanta la capa superficial recortada y en la zona que queda descubierta se efectúa una ablación correspondiente con la forma y espesor de la lentilla a implantar, realizándose esta operación mediante láser excimer en modo PTK.Once the cut is made, the cut surface layer is lifted and in the area that is uncovered, a corresponding ablation is made with the shape and thickness of the lens to be implanted, this operation being performed by excimer laser in PTK mode.
En la ablación realizada se coloca la lentilla coloreada elegida para tal fin, secándose la zona para asegurar la fijación de dicha lentilla, y después se repone la capa superficial de la córnea, con la cual se cubre la lentilla, volviéndose a secar la zona para asegurar la fijación de dicha capa superficial de cubrimiento.In the ablation performed, the colored lens chosen for this purpose is placed, the area being dried to ensure the fixation of said lens, and then the surface layer of the cornea is replaced, with which the lens is covered, the area being dried again to dry ensure the fixing of said surface covering layer.
Las lentillas coloreadas de implantación para dotar a los ojos de la coloración que se desee, pueden ser circulares o anulares, determinando centralmente una zona transparente o vacia en correspondencia con la pupila de los ojos de aplicación, de modo que la ablación para el alojamiento de dichas lentillas se realiza de manera correspondiente con la forma circular o anular de las mismas, realizándose la ablación para el caso de lentillas anulares con ayuda de lentillas máscara correspondientes con dicha forma. Después de implantadas las lentillas coloreadas, éstas pueden ser retiradas mediante una operación sencilla, cuando el portador lo desee, para volver al estado inicial, levantando la capa superficial de la córnea que cubre la lentilla y extrayendo ésta, para volver a reponer la capa superficial de la córnea en su lugar, donde mediante un secado de la zona se asegura la fijación y estabilidad de dicha capa.The colored implant lenses to provide the eyes with the desired color, can be circular or annular, centrally determining a transparent or empty area corresponding to the pupil of the application eyes, so that the ablation for the housing of said contact lenses are made correspondingly with the circular or annular shape thereof, the ablation being performed in the case of annular contact lenses with the help of corresponding contact lenses with said shape. After the colored lenses are implanted, they can be removed by a simple operation, when the wearer wishes, to return to the initial state, lifting the surface layer of the cornea that covers the lens and removing it, to replenish the surface layer of the cornea in place, where by drying the area ensures the fixation and stability of said layer.
En el caso de ser una lentilla anular la que se retira, antes de reponer la capa superficial se realiza una ablación complementaria de la zona central que no habla sido ablacionada para la implantación.In the case of an annular lens that is removed, before replacing the surface layer, a complementary ablation of the central area that does not speak has been ablated for implantation.
El usuario portador de las lentillas coloreadas, puede igualmente cambiar la coloración de sus ojos cuando lo desee, mediante sustitución de las lentillas coloreadas por otras del color deseado, levantando la capa superficial de la córnea que cubre la lentilla y extrayendo ésta, para incorporar en su lugar otra lentilla del color deseado, después de lo cual se repone la capa superficial de la córnea en su lugar y se realiza un secado para asegurar la estabilidad, con lo cual el ojo queda en las mismas condiciones que se hallaba antes de sustituir la lentilla. The wearer of the colored contact lenses can also change the color of their eyes at any time, by replacing the colored contact lenses with others of the desired color, lifting the surface layer of the cornea that covers the contact lens and removing it, to incorporate instead another lens of the desired color, after which the surface layer of the cornea is replaced in its place and drying is performed to ensure stability, whereby the eye is in the same condition as it was before replacing the contact lens.
