El objeto de la presente memoria es un dispositivo de anclaje escleral para lentes intraoculares, cuya principal ventaja distintiva radica en el hecho de conseguir una pieza de material biocompatibie empleado en oftalmología, que permita transformar cualquier lente intraocular convencional en una lente de anclaje escleral. The object of the present specification is a scleral anchoring device for intraocular lenses, whose main distinctive advantage lies in the fact of obtaining a piece of biocompatible material used in ophthalmology, which allows transforming any conventional intraocular lens into a scleral anchoring lens.
Antecedentes de la invención Background of the invention
En la actualidad, en el sector oftalmológico y más concretamente, en el ámbito de las operaciones de cataratas, es común el uso de lentes intraoculares empleadas para su introducción dentro del saco capsular Este tipo de lentes son ampliamente conocidas y existen multitud de productos con diversas formas que cumplen dicha función. At present, in the ophthalmological sector and more specifically, in the field of cataract operations, it is common to use intraocular lenses used for their introduction into the capsular bag.This type of lens is widely known and there are many products with various forms that fulfill this function.
Ahora bien, en dicha operación pueden darse una serie de complicaciones como, por ejemplo, el hecho de que el paciente se quede afáquico (sin soporte donde poder poner la lente intraocular) o bien, que la lente intraocular se caiga al fondo del ojo (ejemplo de complicación durante la cirugía o postquirúrgica tardía). Now, in this operation there may be a series of complications such as, for example, the fact that the patient remains aphakic (without support where the intraocular lens can be placed) or that the intraocular lens falls to the back of the eye ( example of complication during surgery or late postoperative).
Para paliar dicha problemática, el solicitante conoce de varios métodos o procedimientos quirúrgicos que intentan paliar dicha problemática, como, por ejemplo: a) Empleo de una lente escleral del Dr. Carlevale (se trata de una lente intraocular monobloque que se compone de óptica, hápticos y sistema de anclaje escleral monobloque ósea en una sola pieza). Cuenta como inconveniente principal, que su especificidad provoca que no sea fácil conseguir stock, lo que obliga a diferir a un segundo acto quirúrgico su implantación. b) Empleo de una lente de anclaje irídiano (se anclan en el iris a modo de "pinza de cangrejo"). Dicho empleo, provoca problemas inflamatorios, de dispersión del pigmento, área de atrofia iridiana, movimiento de la lente, etc. c) Empleo de lentes intraoculares convencionales suturadas a esclera, o anclando sus hápticos a túneles esclerales (mediante la técnica de Yamane). Cuenta como inconveniente principal· ia laboriosidad de dichas técnicas y ia poca precisión de las mismas. d) Empleo de lentes de cámara anterior que quedan apoyadas en el ángulo camerular, cuentan como inconveniente principal la pérdida de células endoteliales, con toda ia problemática que ello conlleva. To alleviate said problem, the applicant is aware of various methods or surgical procedures that attempt to alleviate said problem, such as: a) Use of a Dr. Carlevale scleral lens (it is a monoblock intraocular lens that consists of optics, haptics and monoblock bone scleral anchoring system in one piece). The main drawback is that its specificity means that it is not easy to obtain stock, which forces its implantation to be deferred to a second surgical act. b) Use of an iris anchoring lens (they anchor in the iris like a "crab claw"). Said use causes inflammatory problems, pigment dispersion, iris atrophy area, lens movement, etc. c) Use of conventional intraocular lenses sutured to the sclera, or anchoring their haptics to scleral tunnels (using the Yamane technique). Count as The main drawback is the laboriousness of these techniques and their low precision. d) The use of anterior chamber lenses that are supported by the chamber angle, the main drawback is the loss of endothelial cells, with all the problems that this entails.
Estas soluciones como se ha comentado, cuentan con el inconveniente principal de tener una baja eficacia, o bien la dificultad para conseguir stock. Por lo que se hace necesaria, una solución eficiente y fácil de obtener, que permita a los cirujanos contar con todas las herramientas necesarias a la hora de realizar una intervención de dicha magnitud y/o complejidad, que pueda derivar en una serie de inconvenientes o problemáticas como las anteriormente descritas y puedan resolverse en el mismo acto quirúrgico. These solutions, as mentioned, have the main drawback of having low efficiency, or the difficulty of obtaining stock. Therefore, an efficient and easy-to-obtain solution is necessary, which allows surgeons to have all the necessary tools when performing an intervention of such magnitude and / or complexity, which can lead to a series of inconveniences or problems such as those previously described and can be resolved in the same surgical act.
Descripción de la invención Description of the invention
El problema técnico que resuelve la presente invención, es conseguir un dispositivo o elemento que permita convertir el uso de lentes intraoculares oftalmológicas en una lente intraoculares de anclaje escleral, con las ventajas que ello subyace en cuanto a el ahorro de costes económicos y la posibilidad de disponer de stock suficiente para las intervenciones de cataratas que puedan derivar en complicaciones ya que se utilizarla la misma lente preseleccionada. Para ello, el dispositivo de anclaje escleral para lentes intraoculares, objeto del presente modelo de utilidad, desarrollado en un material oftalmológicamente biocompatible, está caracterizado porque en un extremo se une a los hápticos de la lente intraocular convencional mediante diversas formas y en su otro extremo incorpora unos medios de anclaje en la esclera. The technical problem solved by the present invention is to achieve a device or element that allows the use of ophthalmic intraocular lenses to be converted into an intraocular lens for scleral anchorage, with the underlying advantages in terms of economic cost savings and the possibility of have sufficient stock for cataract interventions that may lead to complications since the same preselected lens will be used. For this, the scleral anchoring device for intraocular lenses, object of this utility model, developed in an ophthalmologically biocompatible material, is characterized in that at one end it is attached to the haptics of the conventional intraocular lens in various ways and at its other end incorporates anchoring means in the sclera.
Gracias a su diseño, el dispositivo o elemento de anclaje escleral aquí preconizado, podrá ser empleado por cualquier cirujano oftalmológico, de una manera sencilla y rápida trasformando la lente intraocular estándar en una de andaje escleral como la lente de anclaje escleral monobloque conocida en el mercado del Dr, Carlevale sin necesidad de tener el stock necesario que se hace inviable por la especificidad de las lentes según paciente, o de precisar de técnicas o medios de intervención complejos o con posibilidad de que no cumpla con las necesidades impuestas por una cirugía tan compleja. Thanks to its design, the scleral anchoring device or element recommended here can be used by any ophthalmic surgeon, in a simple and fast way, transforming the standard intraocular lens into a scleral gait lens such as the monoblock scleral anchoring lens known in the market. by Dr, Carlevale without the need to have the necessary stock that is made unfeasible due to the specificity of the lenses depending on the patient, or to require complex techniques or means of intervention or with the possibility that it does not meet the needs imposed by such a complex surgery .
Una de las ventajas principales de su uso, es que al poder transformar cualquier lente intraocular en una lente de anclaje escleral, el cirujano podrá emplear la lente inicialmente seleccionada aun cuando aparezcan posibles complicaciones en la cirugía, esto permite una respuesta rápida por parte del personal médico a posibles complicaciones en la operación de cataratas, minimizando los riesgos y daños que pudiera darse en caso de no ser solventados en el momento One of the main advantages of its use is that by being able to transform any lens intraocular lens in a scleral anchoring lens, the surgeon can use the lens initially selected even when possible complications appear in the surgery, this allows a quick response by the medical staff to possible complications in the cataract operation, minimizing the risks and damages that could occur in case of not being solved at the time
De igual forma e intrínsecamente relacionado con lo anterior, el hecho de emplear lentes intraoculares convencionales implica que los hospitales siempre disponen de stock, por lo que, minimiza la espera del paciente en caso de complicación o directamente puede solucionar la problemática in situ, evitando tener que intervenir más de una vez al citado paciente. Similarly and intrinsically related to the above, the fact of using conventional intraocular lenses implies that hospitals always have stock, so it minimizes patient waiting in case of complication or can directly solve the problem in situ, avoiding having to intervene more than once on the aforementioned patient.
En caso de que la lente cayese al fondo del ojo del paciente (complicación durante la cirugía o postquirúrgica) permite el empleo de la propia lente ya utilizada, con una nueva sujeción más estable, lo que permite ahorrar en material quirúrgico. In the event that the lens falls to the back of the patient's eye (complication during surgery or postsurgical), it allows the use of the lens itself already used, with a new, more stable grip, which saves on surgical material.
Todo ello redunda en innumerables beneficios tanto para el centro hospitalario (menos intervenciones, menor ocupación de camas, aumento de otras operaciones, etc.) como para el propio paciente (evitar una segunda operación). All of this results in innumerable benefits both for the hospital center (fewer interventions, less bed occupancy, more operations, etc.) and for the patient himself (avoiding a second operation).
