Cataract surgery is performed in a sterile operating room equipped with state-of-the-art technology. It is carried out under topical anesthesia, that is, with the application of ophthalmic anesthetic drops. The patient feels no pain during the procedure, which lasts only about 10 minutes. The technique consists of practising a micro-incision about the size of the tip of a pencil on the side of the cornea, through which to introduce surgical instruments and a new intraocular lens (IOL). The natural lens to be extracted is in its natural envelope, the “crystalline lens capsule”. The surgeon makes an opening in the front of the capsule to get to the cataract. The cataract is next broken down into small pieces with high-energy ultrasonic waves and aspirated away.
Once the cataract removed, a flexible replacement lens is folded into an injector and inserted into the lens capsule. The central portion of the IOL measures approximately 6 mm and its total diameter is 13 mm, including the small tips (haptics) that support it in the capsule. Most often, no stitches are necessary and the patient can return home shortly after surgery. Follow-up appointments are scheduled one day, one week and one month after the procedure. Normally, the eyes are operated on one at a time a few weeks apart.
Cataract surgery affords the opportunity to correct refractive errors in both eyes. In other words, the IOLs can be chosen in the aim of achieving the best distance vision possible.

Aspherical foldable lens
The aspherical intraocular lens (IOL) gets its name from the design of its optical part, that is, the part where the strength of the lens is located.
The toric lens is qualified as such on account of its optical component. It allows correcting astigmatism.
The multifocal intraocular lens (IOL) allows the eye to focus for both distance and near vision.
Following cataract surgery, an opaque membrane or “secondary cataract” sometimes forms.
