Es una estructura del ojo humano con forma de lente biconvexa que est\u00e1 situado tras el iris y delante del humor v\u00edtreo. Su prop\u00f3sito principal consiste en permitir enfocar objetos situados a diferentes distancias. <\/span><\/div>\n
<\/div>\n
Este objetivo se consigue mediante un aumento o disminuci\u00f3n funcional de su curvatura y de su espesor, proceso que se denomina acomodaci\u00f3n. <\/span><\/div>\n

Se caracteriza por su alta concentraci\u00f3n en prote\u00ednas, que le confieren un \u00edndice de refracci\u00f3n m\u00e1s elevado que los fluidos que lo rodean. Este hecho es el que le otorga su capacidad para refractar la luz, ayudando a la c\u00f3rnea a formar las im\u00e1genes sobre la retina.<\/span><\/div>\n
<\/div>\n
A medida que la edad del sujeto aumenta, el cristalino va perdiendo progresivamente su capacidad para acomodar. Este fen\u00f3meno se conoce como presbicia, presbiop\u00eda o vista cansada, y esto pasa porque el cristalino empieza a perder permeabilidad a las prote\u00ednas, lo que ocasiona en \u00e9l un endurecimiento. <\/span><\/div>\n
<\/div>\n
Afecta a la totalidad de la poblaci\u00f3n a partir de los cincuenta a\u00f1os aproximadamente, exigiendo el uso de lentes para enfocar objetos cercanos. <\/span><\/div>\n

La principal dolencia que afecta al cristalino son las cataratas. Por este nombre se conoce a cualquier p\u00e9rdida de transparencia del mismo que afecte a la visi\u00f3n. Sus causas son diversas y cuando se encuentran en un estado avanzado requieren de una operaci\u00f3n quir\u00fargica.<\/span><\/div>\n","protected":false},"excerpt":{"rendered":"
