Cataracts

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.

The cataract operation involves removing the cloudy lens normally either by laser or ultrasonics and replacing it with an artificial lens or Premium IOL (aspheric intraocular lens, toric for astigmatism correction and multifocal o trifocal to facilitate reading without glasses as appropriate) by micro-incision techniques without suturing.

Multifocal and trifocal intraocular lenses are designed in such way that they allow to obtain simultaneously an appropriate approach from far,intermediate and near simultaneously, making reading glasses unnecessary. The intraocular lens power is calculated from data from a preoperative exploration (biometry) to achieve the best focus after surgery.
