Cataract Surgrey

Cataract is when the natural lens in our eyes, contained between the iris and the vitreous body, becomes opaque. This is due to changes in the chemical composition of the lens like oxidation of lens proteins, which reduces its transparency. There are many reasons, though predominantly it is aging.

The cataract is diagnosed using specific instruments. It is usual to undergo a full regular ophthalmology visit for diagnosis. The only treatment is removal of lens through surgical procedures.

Today in advanced countries, it generally involves the technique known as phacoemulsification, which fragments the lens using ultrasound. The fragments are then removed. A small artificial lens is then implanted. The procedure takes place under local or topical anaesthesia.

A femtosecond laser can also be used to perform even more precise incisions in the cornea to fragment the lens with less trauma (using less ultrasound), and also cut the capsule that contains it more accurately.

Thanks to constant technological progress it is now possible to use intraocular lenses (IOL) that differ in terms of shape, material and size, at different dioptres, to allow maximum adaptability for correcting a greater variety of sight defects and eye structures.

The choice of the most suitable IOL to implant is important for the success of the cataract procedure.

Therefore the specialist, following a thorough consultation and preoperative examinations, will decide whether the patient is a good candidate for the intervention and the best IOL for an optimal result.
