The LASIK technique is not painful, either during or after surgery. Most patients report feeling only pressure from the devices that immobilize the eyes when we perform the surgery. The patient lying on a special bed with a head support that reduces the possibility that this move. Apply eye drops to reduce eye irritation and prevent infection. The surgeon will place a tool that will keep the eye open. From this point begins the actual Lasik surgery which consists of a lift up horny layer of fabric and apply the laser in the interior of the cornea, changing the curvature depending on diopter to correct. If the patient moves his eyes during the action of laser eye tracking tool correct the laser, applying it only ever in the area desired in automatic form. Then reposition the layer previously raised in its original position.
As a surgical technique, Lasik is not without risks, although minimal. Consider that presents less risk to the patient that the use of contact lenses.
Lasik Laser emits energy through a programmed computer that were introduced earlier patient data. Its precision is absolute, They take a level of safety of 0.25 micron (half of a hair). The patient will be in the operating room from 15 to 20 minutes, even if this takes a few seconds. The rest of the time is used to prepare the eye. The Lasik is not acting in the interior of the eye, but only on the outside.
