Presbicia - Información general

Definición:

Es una afección en la cual el cristalino del ojo pierde su capacidad para enfocar, lo que dificulta el hecho de ver objetos cercanos.

Causas, incidencia y factores de riesgo:

La afección está asociada con el envejecimiento y empeora con el paso del tiempo. El poder de enfoque del ojo depende de la elasticidad del cristalino, la cual gradualmente se pierde a medida que las personas envejecen. El resultado es una disminución lenta de la capacidad del ojo para enfocar los objetos cercanos.

Las personas generalmente se percatan de esta afección alrededor de 45 años, cuando se dan cuenta de que necesitan sostener los materiales de lectura a una mayor distancia para poder enfocarlos. La presbicia es una parte natural del proceso de envejecimiento y afecta a todas las personas.
