FAQ's

Most patients who are planning their refractive surgery such as myopia, astigmatism, farsightedness, presbyopia, to dispense to their conventional or contact lenses, they often ask many questions about the operation (LASIK). Trying to clarify their doubts, we have prepared the following questionnaire to their responses, compiled the questions we have other patients who, like you, wanted surgery.

What constitutes art Lasik
The word comes from the English LASIK Laser in situ keratomileusis . The excimer laser, which is the technique used in the procedure, produces a very specific type of energy that changes the curvature of the cornea as if carve the glass of a conventional contact lens, correcting the defect of the patient.

Will I feel pain during or after surgery
LASIK is painless during surgery and afterwards. The patient only felt a slight sting in the hours following it.

What happens during surgery?
During surgery, the patient lies on a special bed with a head restraint that reduces the possibility of moving. Previously, they have instilled a few drops of anesthetic eye drops to reduce discomfort and antibiotics to prevent infection. The surgeon will place an instrument to keep the eyelids open during surgery, preventing these close. Then start the intervention, the first phase is to build a thin layer of corneal tissue. Then the surgeon applies the laser inside the cornea, changing its curvature as required by the patient. During this phase, the surgeon asked the patient to fixate on a central light to ensure proper performance of the laser. If the patient inadvertently move the eye, the eye tracking technology is that the team follows eye movements automatically adjust the computer to apply the laser in the desired area. Finally, the layer of corneal tissue due to its natural grip is repositioned to its initial position without sutures.

When I start to normal life after surgery
after the operation the patient should stay at home, resting for the remainder of the day. The next morning again attend a post-checkup opertoria in which the vision will be assessed. The improvement is so quick and effective that many patients are enough to drive or even go to work. Depending on the number of diopters corrected and the default rate, recovery is more or less quickly, but in general most patients can resume their work and activities at 48-72 hours after surgery.

What kind of precautions should I take after surgery?

The patient will use antibiotic drops, anti-inflammatory and lubricants during the 2 weeks after the operation. These medications can be purchased at the pharmacies. If the patient wishes, the clinic will sell a special medicine kit comes with a special dark glasses and other personal care accessories, in addition to the aforementioned drops. It is totally counter to rub their eyes for at least a month after the intervention, and it is advisable to avoid it during six months. Sporting activities can be practiced if used with proper protective glasses. Avoid makeup during the month following the intervention. We do not recommend going to the beach or into the water during the next 3 months postoperatively.

Does this technique risks
As with any surgical procedure there are risks but these are minimal. The technique has been developed is secure enough to prevent the patient take chances with your vision.

How does the laser?
energy laser emits a programmed by a computer that has been previously entered data of the patient. His performance is so precise that their security lies at 0.25 microns (A human hair is 50 microns).

Can operate both eyes at the same time

Usually both eyes are in the same surgical session, unless the patient prefers to wait between one eye and another. Recent studies have shown that there are medical reasons for not operating on both eyes at the same meeting. If the ophthalmologist in the previous tests found any reason to operate only one eye at a time, will let you know.

How long does the operation?
The patient will be in the operating room about 15 or 20 minutes maximum. The operation itself takes about 15 seconds per eye, on average, depending on the diopters to correct.

How long been practicing this technique?
LASIK experience dates back 25 years, but the technique is based on the keratomileusis which began to make more 40, so we know that is a very safe procedure that we have improved the precision of the laser.

From what age can perform the operation?
Candidates must have at least 18 years of age. This will ensure that the eye has matured and developed properly.

What should I do before going to the consultation? Ideally
stop using contact lenses about 24 hours earlier, are hard or stiff.

affects the laser inside the eye?
, the laser acts on the outer eye and does not penetrate inside. Laser treatment will not alter the performance of a future surgeon if the patient needed any other eye surgery.

Who is a candidate for this technique:
The only way to be sure that you qualify for LASIK surgery is going to an ophthalmologist. However, there are some general conditions:

- Your vision must have been stable for at least the year before surgery.

- You have not had any eye infection or injury for a year,

- The cornea should not have scars,

- very thin cornea People are not good candidates for LASIK.

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

What option is for people who are not candidates for this surgery?

be realized with the modern system with Intralase iLASIK, which favors people who were not candidates for surgery with the traditional system. Intralase system performs the cutting of the cornea using a laser.
