Frequently asked questions (FAQ)
Most patients thinking on correcting their refractive error (Myopia, Astigmatism, Hyperopia) and getting rid of glasses or contacts, have a lot of questions about LASIK.
Trying to answer your doubts about this procedure, we have done this FAQ, from questions we got from other patients that, like you, wanted to be operated on.
- What is LASIK?
- Is there any pain?
- What happens during the LASIK procedure? What if I blink or my eye moves?
- How much time of work do I need to take?
- What are the post-operative restrictions?
- Are there any risks?
- How does the laser work?
- Are both eyes corrected at the same time?
- How long does the surgery take?
- Will I never need glasses again?
- How long has LASIK been using?
- How old I have to be for LASIK?
- I am currently wearing contacts. Do I need to do something special?
- Does the laser affect the inside of my eye?
- Who is not a candidate for LASIK?
- I am interested in having LASIK. What is the next step?
The Excimer laser emits a cool beam of light, that is precisely programmed by the surgeon with the patient data, to reshape the curvature of the cornea and correcting the diopters of myopia, astigmatism, or hyperopia.
Because the laser beam treats the inner portions of the cornea, recovery of the patient is very fast (much more than the older techniques as RK or PRK).
LASIK is nearly painless, during and after the procedure. Most patients only report some discomfort during the surgery due to the instruments used to prevent the eye moving or blinking. The day of the operation you may feel some minor itching.
During LASIK, patients are placed in a comfortable, reclining chair with a headrest. The contour of the headrest reduces the possibility of head movements. Prior to surgery, we give you some antibiotic eye drops, to prevent infections, and anesthetic, to numb your eyes.
Thereafter, your surgeon places some special instruments to prevent blinking or moving your eye during the procedure. Then the laser is applied in the inner layers of the cornea, after pulling back a thin flap of corneal tissue. The laser beam reshapes the cornea and therefore corrects the diopters that have been computer programmed. During the laser application, the patient is asked for fixing his sight in a central light. If the patient moves his eye, the new computerized system "eye tracking" follows the eye movements and allows the laser to be applied in the selected part of the cornea.
No stitches are necessary because the layers of the cornea are naturally "sticky" and will adhere to one another once the flap has been put back into position.
The day of surgery, you need to go home and rest. The next morning, many patients drive by their own for the one day postoperative visit and then go on to work. 1 You will note great improvement in your vision on the first morning post op, but crystal clear vision may take a week or more.
The day of the procedure, you are requested to rest as much as possible.
You will use antibiotic eye drops for a week and anti-inflammatory for two weeks.
Rubbing your eyes is not allowed for a month and you should avoid it for six months.
You can practice your favorite sport if you wear special glasses or goggles.
Avoid make-up for a month.
Similar to any surgical procedure, there are always risks, but it is very unlikely to have any complication in LASIK.
LASIK is considered to have lower exposure to risks than wearing contact lenses. And contacts are a very safe alternative in prescriptive eyewear.
LASIK is one of the safest Ophthalmic procedures and is performed all over the world. (approved by the FDA)
The laser emits a cool beam that is computer programmed by the surgeon with the patient data. This beam reshapes the cornea, removing tissue depending on the amount of diopters of the patient. The laser is accurate to the level of .25 microns (A human hair is 50 microns in diameter).
I prefer to correct both eyes at the same time, because, there are not medical reasons against this, allows the patient to recover clear vision simultaneously, and moreover, avoids the stress of two operations. However, the patient is free to make his own decision.
Having both eyes corrected , you will be at the surgical suite for about 15 minutes. The laser treatment is performed usually in less than a minute, but the entire procedure takes a little longer.
Most patients do not need using glasses in daily activities. In fact, many of them refer better vision after LASIK without glasses, than before with it.
Improve in life quality after LASIK is extraordinary, according to our patients.
LASIK has been performed since 1991, and is based on the Keratomileusis technique, that has been used for more than forty years. So, we have incorporated the accuracy of laser with the safety of a well-known technique.
Age 20 is the youngest we recommend, but if necessary ( Pilots, fireman, policeman, etc.) could be performed younger.
Yes!. You should remove your contacts one week prior to your pre-surgical evaluation if you have soft lenses, and one month before, if you wear rigid gas permeable lenses.
No. The pulses of the laser do not enter the eye at all. If later in your life you develop any Ophthalmic pathology needing surgical treatment as for example, glaucoma or cataract, these conditions can be treated as though you had not had the laser treatment.
Anyone with lupus, rheumatoid arthritis, keratoconus, herpes simplex of the cornea, AIDS, autoinmune diseases is not a candidate for LASIK
