The term cataract refers to the multifactorial opacity of the crystalline ocular lens which can be observed in all age-groups.
The most common form of cataract is due to the normal, age-dependent damage of the lens (senile cataract) and constitutes the main cause of blindness. Cataract can be completely treated with the implementation of special surgical techniques.
The modern and most commonly used surgical technique is worldwide well known as Phacoemulsification.
