LASIK surgery is a procedure. surgical which is done under the influence of a Anesthesia local applied in drops. The LASIK operation consists in making a small incision, by using the microkeratome, in the superficial tissue of the cornea to create a flap (Flap) and then apply excimer laser, previously programmed according to the needs of the patient, to mold the vision defect.
Once the cornea has been molded, the surgeon puts the corneal flap back in place and allows it to heal naturally, without the need for sutures or bandages. The procedure is totally painless and has an approximate duration of 15 minutes If both eyes are treated.

How is the postoperative?
El postoperative LASIK surgery It is much simpler than you think. After surgery, the patient may have some itching, blurred vision u opacity, but all these symptoms are transient and usually disappear the next day.
