   MADRID, 9 Abr. (EUROPA PRESS) – <\/p>\n

   Se prev\u00e9 que el glaucoma afecte a 134 millones de personas para 2040. Si bien el glaucoma es una enfermedad incurable, el diagn\u00f3stico precoz y el tratamiento continuo pueden ralentizar la p\u00e9rdida de visi\u00f3n y preservar la calidad de vida de los pacientes. Sin embargo, el diagn\u00f3stico precoz requiere herramientas fiables<\/strong> que permitan identificar a las personas en riesgo y administrar terapias adaptadas a las necesidades de cada paciente.<\/p>\n

    Un enfoque consiste en el uso de tecnolog\u00edas que monitorizan la presi\u00f3n intraocular elevada,<\/strong> el factor de riesgo modificable m\u00e1s importante para el glaucoma<\/a>. No obstante, las herramientas cl\u00ednicas actuales resultan insuficientes, ya que el m\u00e9todo est\u00e1ndar debe realizarse en la consulta y solo proporciona mediciones cada 6 a 12 meses. <\/p>\n

UNA FARMACIA EN LA LENTILLA<\/h2>\n

    Las lentes de contacto inteligentes electr\u00f3nicas<\/strong> ofrecen una soluci\u00f3n m\u00e1s futurista y pueden monitorizar la presi\u00f3n intraocular de forma continua, pero dependen de componentes electr\u00f3nicos r\u00edgidos y fuentes de alimentaci\u00f3n externas, y suelen ser inc\u00f3modas o incluso peligrosas de usar.<\/p>\n

   Una lente de contacto inteligente sin bater\u00eda puede monitorizar la presi\u00f3n intraocular y liberar diversos f\u00e1rmacos para el glaucoma, controlando as\u00ed el aumento de presi\u00f3n en tiempo real, tal y como se ha observado en un nuevo estudio del Instituto Terasaki para la Innovaci\u00f3n Biom\u00e9dica (Estados Unidos) realizado con conejos y un modelo ocular ‘ex vivo’.<\/p>\n

   Tal y como se publica en ‘Science Translational Medicine’,<\/a> esta lente se distingue de dise\u00f1os anteriores por su simplicidad, comodidad y la ausencia de componentes electr\u00f3nicos voluminosos, sentando las bases para una nueva generaci\u00f3n de tecnolog\u00edas personalizadas para el cuidado de la vista.<\/p>\n

LAS PRIMERAS PRUEBAS YA FUNCIONAN<\/h2>\n

    Los autores presentan un dise\u00f1o m\u00e1s sencillo y c\u00f3modo: la lente de contacto inteligente teran\u00f3stica totalmente polim\u00e9rica. Esta lente se basa en componentes polim\u00e9ricos de bajo coste, un sensor de presi\u00f3n intraocular microflu\u00eddico y una esponja de seda biomim\u00e9tica que mejora la sensibilidad.<\/p>\n

Tambi\u00e9n incluye un compartimento que puede liberar m\u00faltiples dosis de f\u00e1rmacos si detecta picos de presi\u00f3n intraocular<\/strong>. En pruebas realizadas en conejos y ojos de vaca ex vivo, la lente monitoriz\u00f3 de forma fiable la presi\u00f3n intraocular y liber\u00f3 dosis de los f\u00e1rmacos aprobados para el glaucoma, timolol o brimonidina, en los umbrales de presi\u00f3n actuales.<\/p>\n

    Este trabajo sienta las bases para el desarrollo de una familia de herramientas de farmacia en una lente de contacto capaces de proporcionar informaci\u00f3n cl\u00ednicamente relevante sobre la salud humana, seg\u00fan los investigadores. A\u00f1aden que su plataforma es compatible con lentes comerciales<\/strong> y podr\u00eda reconfigurarse para una amplia gama de aplicaciones en el cuidado de la vista. <\/p>\n","protected":false},"excerpt":{"rendered":"
