SOPORTE PARA LENTE INTRAOCULAR EN CAMARA POSTERIOR SUPPORT FOR INTRAOCULAR LENS IN BACK CAMERA
DESCRIPCIÓN DESCRIPTION
OBJETO DE LA INVENCION OBJECT OF THE INVENTION
La presente invención se refiere a un soporte para lente intraocular en cámara posterior. También incluye unas mejoras o prestaciones adicionales para dicho soporte. The present invention relates to a support for intraocular lens in posterior chamber. It also includes some improvements or additional features for this support.
ANTECEDENTES DE LA INVENCION BACKGROUND OF THE INVENTION
En operaciones del ojo humano que precisan la inserción de una lente intraocular, típicamente en operaciones de cataratas, la primera opción médica es la realización de un rasgado anterior circular continuo de la cápsula que envuelve el cristalino por su parte anterior, técnica denominada capsulorhexis anterior circular continua, para la extracción del cristalino y posterior implantación en el interior de dicha cápsula de la lente intraocular que sustituye al cristalino. Estas lentes intraoculares cuentan con unas patillas salientes en sentido ligeramente tangencial, llamadas asas hápticas, que al empujar contra las paredes de la cápsula mantienen a la lente intraocular en posición centrada. In operations of the human eye that require the insertion of an intraocular lens, typically in cataract operations, the first medical option is to perform a continuous circular anterior tear of the capsule that wraps the lens through its anterior part, a technique called circular anterior capsulorhexis. continuous, for the extraction of the lens and subsequent implantation inside said capsule of the intraocular lens that replaces the lens. These intraocular lenses have protruding tabs in a slightly tangential sense, called haptic loops, which when pushed against the walls of the capsule keep the intraocular lens in a centered position.
A veces, durante la cirugía surge la complicación de que se rompe la pared posterior de la cápsula, que la separa del humor vitreo, lo que impide la implantación de la lente intraocular en el interior de la cápsula ya que caería hacia el interior del ojo, aunque si se mantiene la capsula anterior con su rhexis la lente se podría colocar sobre ella con aceptable estabilidad. Otras veces el origen de la complicación es que no se consigue una capsulorhexis completa, y entonces no podríamos poner la lente intraocular sobre ella porque no quedaría estable y se podría precipitar al vitreo. En estos casos existen técnicas alternativas como la utilización de lentes de cámara anterior, lentes suturadas a sulcus, o lentes pinzadas a iris, todas ellas no siendo una alternativa óptima ya que no se puede garantizar el centrado de la lente intraocular con precisión. Sometimes, during surgery, the complication arises that the posterior wall of the capsule ruptures, separating it from the vitreous humor, which prevents the implantation of the intraocular lens inside the capsule as it would fall into the eye. , although if the anterior capsule is maintained with its rhexis the lens could be placed on it with acceptable stability. Other times the origin of the complication is that a complete capsulorhexis is not achieved, and then we could not put the intraocular lens on it because it would not be stable and could be precipitated to the vitreous. In these cases there are alternative techniques such as the use of anterior chamber lenses, sulcus-sutured lenses, or iris-clamped lenses, all of which are not an optimal alternative since the centering of the intraocular lens can not be guaranteed with precision.
DESCRIPCION DE LA INVENCION DESCRIPTION OF THE INVENTION
El soporte para lente intraocular en cámara posterior de la invención tiene una configuración que permite una colocación eficazmente inmovilizada, estable y centrada de la lente
infraocular en cámara posterior, como si de una capsulorhexis natural se tratase, funcionando como si fuese una segunda rhexis. The posterior chamber intraocular lens holder of the invention has a configuration that allows for an effectively immobilized, stable and centered positioning of the lens infraocular in the posterior chamber, as if it were a natural capsulorhexis, working as if it were a second rhexis.
De acuerdo con la invención, el soporte comprende una porción de material consistente (lo que en el presente documento quiere significar que es capaz de proporcionar un apoyo a la lente intraocular cuando no hay rhexis natural suficiente para darle a la lente una estabilidad segura, sustituyendo así a dicha rhexis natural aunque no haya ningún vestigio de capsula), y provista de un hueco central para el paso de las imágenes al interior del ojo, y provista también de medios de sujeción al ojo. According to the invention, the support comprises a portion of consistent material (which in the present document means that it is capable of providing support to the intraocular lens when there is not sufficient natural rhexis to give the lens a secure stability, substituting thus to said natural rhexis although there is no vestige of capsule), and provided with a central hole for the passage of the images to the interior of the eye, and also provided with means of fastening to the eye.
De esta forma podemos fijar el soporte de la invención en cámara posterior (tras el iris) externalizando sus asas hápticas por el sulcus (zona del ojo que esta detrás del iris) introduciéndolas en túnel intraescleral creado para ello, y posteriormente sobre este soporte implantar la lente intraocular, que podrá ser centrada respecto del soporte, que sí que queda fijo, sin que pueda caer al interior del ojo. In this way we can fix the support of the invention in the posterior chamber (after the iris) by externalizing its haptic loops through the sulcus (area of the eye behind the iris) introducing them into the intrascleral tunnel created for it, and later on this support to implant the intraocular lens, which can be centered on the support, which itself is fixed, without falling inside the eye.

De esta forma se puede colocar la lente intraocular sobre este soporte (1 ) como si se tratase de una segunda rhexis. El hueco central (30) igualmente facilita la inserción del soporte (1 ) al reducir su tamaño, ya que reduce el tamaño de la incisión necesaria para su colocación y se puede introducir enroscada.
Los medios de sujeción al ojo comprenden unas asas hápticas (5) para por ejemplo salir del ojo a través del sulcus e introducirlas en túnel escleral creado. Dichas asas hápticas (5) comprenden idealmente unos ojales (50) extremos para facilitar el suturado y su extracción del ojo The support (1) for posterior chamber intraocular lens (2) (20) comprises a portion (3) of consistent material provided with a central recess (30) for the passage of images into the eye (4) , and provided with means of fastening to the eye (4). In this way, the intraocular lens can be placed on this support (1) as if it were a second rhexis. The central recess (30) also facilitates the insertion of the support (1) by reducing its size, since it reduces the size of the incision necessary for its placement and can be screwed in. The means of fastening to the eye comprise haptic handles (5) for, for example, leaving the eye through the sulcus and introducing them into the created scleral tunnel. Said haptic loops (5) ideally comprise end eyelets (50) to facilitate suturing and removal of the eye

Most preferably, the portion (3) has a circular crown shape, since it adopts a round outer shape to adapt to the shape of its location in the eye and materializing the central hole (30) also in round shape.
Idealmente la porción (3) tiene forma de corona circular abierta, de forma que la abertura (31 ) de la misma permite poder introducirla por una incisión corneal más pequeña que las que hay que realizar cuando una lente intraocular rígida se fija directamente en sulcus, minimizando la agresividad de la intervención. La amplitud de la corona circular abierta queda idealmente comprendida entre 180 y 350 grados, y muy preferentemente puede ser de 300 o 310 grados para conseguir una buena estabilidad de soporte con un mínimo tamaño. Igualmente se ha previsto que la corona circular tenga un diámetro interior comprendido entre 4 y 5 milímetros y un diámetro exterior comprendido entre 8 y 12 milímetros para poder adaptarse a cualquier ojo. Unos valores muy típicos podrían ser un diámetro interior de 4,5 milímetros y/o un diámetro exterior de 10 milímetros. Ideally, the portion (3) has the shape of an open circular crown, so that the opening (31) thereof allows it to be introduced through a smaller corneal incision than those that must be performed when a rigid intraocular lens is fixed directly in sulcus, minimizing the aggressiveness of the intervention. The width of the open circular crown is ideally comprised between 180 and 350 degrees, and very preferably it can be 300 or 310 degrees to achieve good support stability with a minimum size. It has also been foreseen that the circular crown has an internal diameter comprised between 4 and 5 millimeters and an outer diameter comprised between 8 and 12 millimeters to be able to adapt to any eye. Typical values could be an inside diameter of 4.5 millimeters and / or an outside diameter of 10 millimeters.
Indicar que la porción (3) puede estar realizada en material coloreado como el iris para conseguir efectos estéticos y protección de la luz en lesiones en las que falte una porción del iris. Idealmente se encuentra materializada en PMMA (polimetilmetacrilato) ya que es un material con buena resistencia y, transparencia. Las asas hápticas (5) se encuentran idealmente integradas en la porción (3) en configuración monobloque pudiendo haber una angulación de 5-10 grados entre porción (3) y las asas hápticas (5). Indicate that the portion (3) can be made of colored material such as the iris to achieve aesthetic effects and protection of light in lesions in which a portion of the iris is missing. Ideally it is materialized in PMMA (polymethylmethacrylate) since it is a material with good resistance and transparency. The haptic loops (5) are ideally integrated in the portion (3) in a monobloc configuration, with an angle of 5-10 degrees between the portion (3) and the haptic loops (5).
Se han previsto una mejoras a la configuración anteriormente descrita (ver fig 3), las cuales comprenden la posible disposición de, al menos, un retenedor (7) para la lente (2), para inmovilizar y centrar dicha lente (2) intraocular que se colocaría en el centro de la rhexis conseguida con el soporte (1 ).

Most preferably, said retainer (7) or retainers comprises a finger made of the same material as the support (1), which, in addition to being material compatible with the intended use, can be manufactured in a monobloc configuration as a whole.
La configuración ideal para estos retenedores (7) en forma de uña sería que estén unidos y
dimanando únicamente del borde externo (33) de la porción (3) y se encuentren dirigidos hacia su borde interior (34) funcionando así como una pinza o abrazadera y ocupando el mínimo espacio posible. Los extremos (70) de los retenedores (7) de uña pueden morir en el borde interior (34) de la porción (3), quedarse cerca del mismo como se ve en la vista izquierda de la fig 3 o sobrepasarlo como se ve en la vista derecha de la fig 3. Además, el número de retenedores (7) de uña preferido estaría por ejemplo comprendido entre uno y cuatro The ideal configuration for these nail-shaped retainers (7) would be that they are joined and emanating only from the outer edge (33) of the portion (3) and are directed towards its inner edge (34) functioning as well as a clamp or clamp and occupying the minimum possible space. The ends (70) of the nail retainers (7) can die at the inner edge (34) of the portion (3), stay close to it as seen in the left view of fig 3 or surpass it as seen in the right view of fig 3. Furthermore, the number of preferred nail retainers (7) would be, for example, between one and four
