Common Questions Asked About LASIK

What is Lasik technique?

Using the excimer laser, which produces a type of energy very accurately and safe for ocular tissues, change the curvature of the cornea as if a glass puliéramos glasses or a contact lens, correcting the patient's defect. This curvature change is made within the corneal tissue and thus healing and therefore the recovery of the patient is much faster than other techniques.

Will I feel pain during or after the operation?

The LASIK technique is not painful during or after surgery. Most patients report a sensation of pressure only due to the devices that immobilize the eye when performing surgery, and slight sting in the hours following it.

What happens during the procedure? What will happen if I blink or move the eye?

During the procedure, the patient is lying on a special bed with a headrest, which reduces the possibility of moving. Have previously been instilled anesthetic eye drops to reduce discomfort, and antibiotic, to prevent infection.

Surgeon place an instrument to maintain the eye open during surgery, preventing flickering. From now on the operation begins; the first part is to build a thin layer of corneal tissue and then applying the laser inside the cornea, changing its curvature as to correct the diopter. During this phase, the surgeon will ask the patient to fixate on a central light to ensure proper performance of the laser. If the patient inadvertently move the eye, new computers that have "eye tracking" are able to track eye movements and the laser is applied automatically to the desired area.

Finally, corneal tissue layer due to its natural adhesion is repositioned in its initial position without stitches. When can I start a normal life after surgery?

After the operation the patient should be at home resting about 24 hours.

The next morning, the improvement is so important that many patients see well enough to drive and even go to work. Depending on the number of diopters corrected and the type of fault recovery is much faster, but in general most patients can return to work and activities at 48-72 hours after surgery.

What kind of precautions should I take after surgery?

The patient will use a few drops (antibiotics and anti-inflammatory) for 15 days. It is totally counter rubbing your eyes for at least a month after surgery, and should be avoided over six months.

Sports can be practiced whenever used protective goggles.

Have to avoid makeup during the month after the intervention.

Does this technique have any risk?

As with any surgical procedure there are always risks, but these are minimal.

LASIK is considered to present less possibility of risk to the patient than the use of contact lenses. The technique is as safe practice in most countries (including USA) and since it began in 1991 there have been hundreds of thousands of interventions and improvements.

How does the laser work?

The laser emits energy scheduled intensities that have been previously introduced in relation to each patient data. It's performance is so precise that their security level is at 0.25 microns (a human hair is 50 microns).

Can both eyes be operate at the same time?

Yes, usually both eyes in the same surgical session, unless the patient prefers to wait between one eye and the other.

Recent studies have shown that there are no medical reasons not to do it this way, and yes there are reasons for, as the patient has the advantage of recovering from both eyes at once and not repeat the stress of a new intervention.

How long is the operation?

The patient is in the operating room 15 to 20 minutes maximum. The operation itself takes seconds, depending on the diopter. The rest of the time is used to prepare the eye for laser application.

Do I need to wear glasses after surgery?

Most patients can perform normal activities without using glasses. In fact, many patients are better after the operation without glasses before them. The improvement in quality of life, according to the testimonies of people operated, is extraordinary.

Only in the case of having more than 45 years, you should probably use near correction as anyone of that age.

How long have you been practicing this technique?

The LASIK experience dates back some years ago, but the technique is based on keratomileusis which began conducting more than 40 years, so we know it is a very safe procedure that we have perfected with laser precision.

From what age can the operation be perform?

From age 20, but if required for professional reasons (Pilots, police, firefighters, etc..) Can be younger.

I'm using contact lenses what should I do before going to the office?

The ideal is to stop using contact lenses a week before going to see if they are soft and a month if they are semi-rigid or rigid. If not possible, at least not use them during the weekend prior to the query, then depending on the state of the cornea will be encouraged to use or not to leave them longer.

Does it affect the laser inside the eye?

No, the laser acts on the outside of the eye, and does not enter inside. Laser treatment does not change the performance of the surgeon if in the future, the patient will need any other eye surgery.

Who is not a candidate for this technique?

Patients with collagen diseases (lupus, rheumatoid arthritis), keratoconus, corneal herpes, AIDS, or autoimmune diseases are not candidates for this surgery.
