Description
Dispositivo para el estudio de radios y potencias queratométricas.Device for studying radios and keratometric powers.
La invención se encuadra en el sector de la Optometría y la Tecnología Óptica, más concretamente en lo relativo a la medición de radios y potencias queratométricas.The invention falls within the sector of Optometry and Optical Technology, more specifically in relation to the measurement of radii and keratometric powers.
El astigmatismo corneal es el error refractivo que produce una imagen distorsionada de un punto.Corneal astigmatism is the refractive error which produces a distorted image of a point.
En Optometría, para medir el astigmatismo corneal con el objetivo de corregirlo por medio de lentes tóricas, se utiliza la queratometría que consiste en la medida de los radios y potencias de los ejes principales de la cornea.In Optometry, to measure astigmatism corneal in order to correct it by means of toric lenses, keratometry is used consisting of the radius measurement and powers of the main axes of the cornea.
Habitualmente la queratometría se realiza utilizando queratómetros manuales y automáticos. Los queratómetros manuales se caracterizan porque el observador debe alinear dos imágenes en dos direcciones concretas que corresponden a los dos ejes principales de mirada del ojo. Estas imágenes reúnen unas características específicas para permitir al observador definir con precisión tales ejes. Los queratómetros automáticos realizan las mismas medidas con la ayuda principal de infrarrojos y ofrecen los resultados en una pantalla digital. Existen queratómetros automáticos o autoqueratómetros que realizan las mismas medidas que los queratómetros manuales pero de forma más rápida, utilizando un disparo efectuado por el profesional en base a una imagen nítida que percibe en el visor. El autorrefractómetro, por otro lado, suele incluir este sistema de medida como un dato adicional a los que pueda integrar este instrumento óptico.Keratometry is usually performed using manual and automatic keratometers. Keratometers manuals are characterized because the observer must align two images in two specific directions that correspond to the two main axes of eye gaze. These images bring together specific characteristics to allow the observer to define with precision such axes. Automatic keratometers perform the same measurements with the main infrared support and offer the Results on a digital screen. There are keratometers automatic or autokeratometers that perform the same measurements as manual keratometers but faster, using a shot by the professional based on a clear image that you perceive in the viewfinder. The auto refractometer, on the other hand, usually include this measurement system as additional data to those I can integrate this optical instrument.
Relacionadas con dispositivos que incluyen soportes adaptables a los instrumentos ópticos existen algunas invenciones especialmente preocupadas por conseguir medir los parámetros de lentes de contacto sin modificar las paredes o los bordes de dichas lentes. En este sentido la patente US4262966 se refiere a un soporte de lentes de contacto con el que sostener las lentes sin modificar sus superficies y en cualquier posición en relación con un instrumento óptico, de manera que se puedan analizar los parámetros de las lentes. Este dispositivo tiene una serie de elementos con las características adecuadas para que no dañe las lentes, para que la reflexión de la luz no interfiera en los análisis a realizar, para proteger la lente de contaminantes y para alinear el instrumento óptico con los ejes de las lentes de contacto. Otro dispositivo más sencillo se presenta en la patente US4786144 que se refiere a un soporte para lentillas con distintos accesorios en función del tipo de lente que se desea estudiar (hidrofílicas o rígidas) y que se puede unir a otro soporte de manera que se mantenga ante el aparato de medición. También se conocen lentes de material plástico pegadas en el oclusor del equipo óptico para el calibrado de los queratómetros manuales o, en su defecto, una bola metálica esférica sobre soporte vertical en mentonera. Las pastillas de material orgánico utilizadas para el calibrado convencional del aparato queratométrico son esféricas y de potencias y radios iguales en todas las direcciones. Además, en la actualidad es conocido el empleo de dispositivos de superficie esférica para el calibrado de aparatos de optometria, como los oclusores de los queratómetros convencionales. Entre estos dispositivos pueden encontrarse bolas de acero que algunas casas comerciales suministran junto con los aparatos de optometría para su calibrado.Related to devices that include adaptable media to optical instruments there are some inventions especially concerned with measuring contact lens parameters without modifying the walls or edges of said lenses. In this sense the patent US4262966 is refers to a contact lens holder with which to hold the lenses without modifying their surfaces and in any position in relationship with an optical instrument, so that they can analyze the parameters of the lenses. This device has a series of elements with the appropriate characteristics so that no damage the lenses, so that the reflection of the light does not interfere in the analyzes to be performed, to protect the lens from contaminants and to align the optical instrument with the axes of the lenses of Contact. Another simpler device is presented in the patent. US4786144 which refers to a support for contact lenses with different accessories depending on the type of lens you want to study (hydrophilic or rigid) and that can be attached to another support of so that it remains before the measuring device. I also know they know plastic lenses attached to the occluder of the optical equipment for calibrating manual keratometers or, in failing that, a spherical metal ball on vertical support in chin guard The organic material tablets used for Conventional calibration of the keratometric apparatus are spherical and of equal powers and radii in all directions. Also in The use of surface devices is now known spherical for the calibration of optometry devices, such as occluders of conventional keratometers. Between these devices can be found steel balls that some houses commercial supplies along with optometry devices for its calibration
Esta invención se refiere a un dispositivo que comprende un soporte de un material sensiblemente rígido, al que se le adhieren uno o más elementos que simulan el ojo humano. El material utilizado para fabricar el soporte puede ser metálico, plástico, metacrilato, porcelana, cristal, madera o cualquier otro que confiera rigidez al dispositivo y la lámina que lo conforma tiene dimensiones milimétricas. En cuanto a los elementos que simulan el ojo humano, pueden ser de un material moldeable con una curvatura variable en sus ejes principales, de superficie reflejante que permita la visualización dentro del instrumento de las imágenes vistas de un ojo humano cualquiera, y se colocan enfrente del queratómetro. Además, se debe utilizar un material adecuado para tener una buena calidad óptica de la superficie. Pueden ser pastillas de lentes de contacto sin acabar, adheridas al dispositivo por la superficie plana. Estas pastillas son cilindros de un diámetro variable, entre 12 y 16 mm aproximadamente, con un grosor suficiente para su pulido en máquinas específicas para su manipulación y posterior acabado, cuya fabricación está normalizada. Su finalidad habitual es su uso para generar lentes de contacto bien rígidas, semirrígidas o hidrofílicas, con diferentes composiciones químicas del material plástico según el uso final y las necesidades del ojo al que van destinadas. En esta invención, dado que el ojo humano tiene diferentes valores en la superficie corneal anterior, utilizando pastillas con radios y potencias diferentes más cercanas al ojo se consigue la simulación necesaria para su medida objetiva. Por lo tanto, sea cual sea el elemento que se utilice para simular el ojo humano, el diseño se realiza de manera que simule un astigmatismo queratométrico en el rango que tiene una córnea humana y así los simuladores de ojo artificial pueden ser esféricos o astigmáticos en cualquier potencia tanto cóncavos como convexos y se pueden cambiar en el soporte por otros elementos que simulen distintas características de la córnea humana. La potencia será la adecuada al rango del aparato que se vaya a utilizar. La unión de los elementos que simulan el ojo humano al soporte se puede realizar mediante pegamento, cinta adhesiva de doble cara o materiales similares.This invention relates to a device that it comprises a support of a substantially rigid material, to which One or more elements that simulate the human eye adhere to it. He material used to make the support can be metallic, plastic, methacrylate, porcelain, glass, wood or any other that confers rigidity to the device and the sheet that conforms it It has millimeter dimensions. As for the elements that they simulate the human eye, they can be of a moldable material with a variable curvature on its main axes, with a reflective surface that allows the visualization inside the instrument of the images views of any human eye, and are placed in front of the keratometer In addition, a suitable material should be used for have a good optical surface quality. They may be unfinished contact lens pads, attached to the device by the flat surface. These pads are cylinders of a variable diameter, approximately 12 to 16 mm, with a thickness enough for polishing on specific machines for your handling and subsequent finishing, whose manufacturing is standardized. Its usual purpose is its use to generate contact lenses either rigid, semi-rigid or hydrophilic, with different chemical compositions of the plastic material according to the end use and the needs of the eye to which they are intended. In this invention, since the human eye has different surface values anterior corneal, using pads with radii and powers different closer to the eye you get the necessary simulation for your objective measurement. Therefore, whatever the element that be used to simulate the human eye, the design is made of so that it simulates a keratometric astigmatism in the range that it has a human cornea and so the artificial eye simulators they can be spherical or astigmatic in any power both concave as convex and can be changed in the support by others elements that simulate different characteristics of the cornea human The power will be adequate to the range of the device that is I will use. The union of the elements that simulate the eye Human to the support can be done by glue, tape double-sided adhesive or similar materials.
Una abertura lateral en la base del dispositivo permite acoplar el soporte a un instrumento óptico utilizando uno o varios elementos de sujeción para amordazarlo a la mentonera. El instrumento óptico al que se acopla el soporte es la mentonera donde va instalado el queratómetro, el autorrefractómetro o el autoqueratómetro y el sistema de unión puede ser tan sencillo como el empleo de un tornillo.A side opening at the base of the device it allows to attach the support to an optical instrument using one or several fasteners to muzzle the chin guard. He optical instrument to which the support is attached is the chin guard where the keratometer, the self-refractometer or the Autokeratometer and the joint system can be as simple as The use of a screw.
El nuevo dispositivo es útil para todas aquellas aplicaciones en las que sea una ventaja simular pruebas de optometría, contactología u oftalmología sin recurrir a los ojos humanos. Se puede utilizar como prueba objetiva de evaluación, con el uso de superficies similares con diferentes valores de radios y potencias.The new device is useful for all those applications in which it is an advantage to simulate tests of optometry, contactology or ophthalmology without resorting to the eyes humans. It can be used as an objective evaluation test, with the use of similar surfaces with different radius values and powers
Por ejemplo, en la queratometria sobre ojo humano, confluyen una diversidad de inconvenientes para la práctica de la técnica en la formación de futuros ópticos-optometristas como son: la falta de lágrima que produce distorsión de la imagen, el exceso de parpadeo, los movimientos bruscos del paciente, desorientando la fijación del área de observación y los movimientos bruscos del aparato de observación entre otros. El uso del dispositivo de la presente invención evita un retraso considerable en la práctica de equipos queratométricos puesto que elimina el 75% de estos problemas. Esta nueva herramienta, al eliminar la necesidad de aprender en ojos humanos, favorece la precisión y ejercicio de la medida, disminuyendo el tiempo de enseñanza. De esa forma reducimos el número de prácticas sin variar la dificultad de la prueba.For example, in keratometry over eye human, converge a variety of inconveniences to practice of the technique in the formation of futures Opticians-optometrists such as: lack of tear which produces image distortion, excess flickering, abrupt movements of the patient, disorienting the fixation of the observation area and abrupt movements of the apparatus of observation among others. The use of this device invention avoids a considerable delay in the practice of equipment keratometric since it eliminates 75% of these problems. This new tool, by eliminating the need to learn in eyes human, it favors the precision and exercise of the measurement, decreasing teaching time. That way we reduce the number of practices without varying the difficulty of the test.
