Las cataratas son una de las razones más frecuentes de deterioro visual y afectan a la mayoría de las personas con la edad. Son la causa de ceguera más frecuente en todo el mundo.
Los pacientes a menudo no se dan cuenta de que tienen cataratas hasta que la visión borrosa empieza a afectar drásticamente a su vida cotidiana. Si no se tratan, las cataratas pueden llegar a producir ceguera. La parte positiva es que pueden tratarse con facilidad y eficacia mediante un procedimiento seguro y rutinario. En la actualidad, la sustitución del cristalino enturbiado por cataratas mediante una lente intraocular (LIO) se realiza más de 20 millones de veces al año en todo el mundo1.
