Abstract
Description
La presente invención se refiere a un soporte para lente intraocular en cámara posterior. The present invention relates to a support for intraocular lens in the posterior chamber.
10 10
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 15 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 the realization of 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 pins in a slightly tangential direction, called haptic handles, which when pushed against the capsule walls 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 20 cápsula, que la separa del humor vítreo, 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 25 podría precipitar al vítreo. 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 is broken, which separates it from the vitreous humor, which prevents the implantation of the intraocular lens inside the capsule as it would fall into the interior of the capsule. 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 the vitreous could be precipitated. In these cases there are alternative techniques such as the use of anterior chamber lenses, sulcus sutured lenses, or iris-clamp lenses, all of them not being an optimal alternative since the centering of the intraocular lens cannot be guaranteed with precision.

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 The intraocular lens holder in the posterior chamber of the invention has a configuration that allows an effectively immobilized, stable and centered lens placement
intraocular en cámara posterior, como si de una capsulorhexis natural se tratase, funcionando como si fuese una segunda rhexis. intraocular in the posterior chamber, as if it were a natural capsulorhexis, functioning 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 5 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. In accordance with the invention, the support comprises a portion of consistent material (which herein means that it is capable of providing support to the intraocular lens when there is not enough natural rhexis to give the lens a secure stability, thus replacing said natural rhexis although there is no vestige of the capsule), and provided with a central opening for the passage of the images inside the eye, and also provided with means of attachment to the eye.

El soporte (1) para lente (2) intraocular en cámara posterior (20) de la invención comprende una porción (3) de material consistente provista de un hueco central (30) para el paso de las imágenes al interior del ojo (4), y provista de medios de sujeción al ojo (4). 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 30 tamaño, ya que reduce el tamaño de la incisión necesaria para su colocación y se puede introducir enroscada. The support (1) for intraocular lens (2) in the posterior chamber (20) of the invention 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 fastening means 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 hole (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.
Los medios de sujeción al ojo comprenden unas asas hápticas (5) para por ejemplo salir del The means for attaching to the eye comprise haptic handles (5) for example leaving the
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 eye through the sulcus and introduce them into created scleral tunnel. Said haptic handles (5) ideally comprise eyelets (50) ends to facilitate suturing and removal of the eye
Muy preferentemente la porción (3) tiene forma de corona circular, ya que adopta forma 5 exterior redonda para adaptarse a la forma de su emplazamiento en el ojo y materializando el hueco central (30) también en forma redonda. Very 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 hollow (30) also in a 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 10 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 15 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 by a smaller corneal incision than there are to be made when a rigid intraocular lens is fixed directly on sulcus , minimizing the aggressiveness of the intervention. The amplitude of the open circular crown is ideally between 180 and 350 degrees, and most preferably it can be 300 or 310 degrees to achieve good support stability with a minimum size. It is also provided that the circular crown has an inner diameter between 4 and 5 millimeters and 15 an outer diameter between 8 and 12 millimeters to adapt to any eye. Very typical values could be an inner diameter of 4.5 millimeters and / or an outer diameter of 10 millimeters.
Por último indicar que la porción (3) puede estar realizada en material coloreado como el iris 20 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) 25 Finally, indicate that the portion (3) can be made of colored material such as iris 20 to achieve aesthetic effects and light protection in lesions where 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 handles (5) are ideally integrated in the portion (3) in monobloc configuration and there may be an angle of 5-10 degrees between the portion (3) and the haptic handles (5) 25
