A cataract is the clouding or loss of transparency of the crystalline lens due to various causes: age, congenital, trauma, systemic diseases, etc.. The symptoms are usually manifested by a decrease in visual acuity, the difficulty in adapting to the dark vision and / or increased glare.
With the available technology and the sophistication of surgycal technique, the patient benefits from a less invasive surgery and very fast postoperative recovery. Nowadays people suffering from cataracts don´t need to suffer deterioration in visual function over a long period of time before being treated. In fact, the safety and efficacy of these operations are so high, that at present they can be indicated for purely refractive correction, i.e. to eliminate the use of eyeglasses or contact lenses, even when the cataract has not appeared yet.
