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). To clarify doubts, we have prepared the following questionnaire to their responses.
What takes place 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. The first phase is to build a thin layer of corneal tissue. The surgeon applies the laser inside the cornea, changing its curvature required by the patient. The eye tracking technology follows eye movements automatically and adjusts the computer to apply the laser in the desired area. Finally, due to its natural grip the layer corneal tissue is repositioned to its initial position without sutures.
When can I start a standard life after surgery
after the operation the patient should stay at home and rest for the remainder of the day. The next morning the patient should attend a post-checkup in which the vision will be assessed. The improvement is so quick and effective that many patients are able to drive or even go to work withing the next few days. In general most patients can resume their work and activities at 24-48 hours after surgery.
What kind of precautions should I take after surgery?
The patient will use antibiotic and anti-inflammatory drugs for 2 weeks and lubricants for 10 weeks after the procedure. These medications can be purchased at any pharmacy. If the patient wishes, the clinic will sell a special medicine kit that comes with a special dark glasses and other personal care accessories. It is total contraindicated to rub the eyes for at least a month after the process. Sporting activities can be practiced if used with proper protective glasses. Avoid eye makeup during the month following the surgery. We do not recommend going to the beach or into the water during the next 1 month postoperatively.
What are the risks for this procedure?
As with any surgical procedure there are risks but these are very minimal. The technique has been developed to bs secure enough to prevent the patient s vision to worsen.
How does the laser work?
An Excimer laser reshapes the cornea to correct myopia, pyperopia, astigmatism or presbyopia. This preformance is very precise and less than 3% need retreatment.
Can both eyes be operated on the same day?
Usually both eyes are operated on the same day. Recent studies have shown no medical reasons not to operate on both eyes at the same meeting.
How long does the operation take?
The patient will be in the operating room for approximately 15 minutes. The laser itself takes about 30 seconds per eye on average.
How many years has this technique been practiced?
LASIK experience dates back 25 years, but the technique is based on the keratomileusis which began more than 40 years, so we know that is a very safe procedure that has improved significantly.
what age is considered appropriate to be a candidate for LASIK ?
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?
stop using contact lenses about 24 hours earlier, especially if they are hard or stiff.
does the laser affect the inside of 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, here 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,
- People with very thin cornea are not good candidates for LASIK.
- Patients with collagen diseases (lupus, rheumatoid arthritis), keratoconus, corneal herpes, AIDS, or autoimmune diseases are not considered candidates for this surgery.
What are some option for people who are not candidates for this surgery?
View the Clinic s website for any other possible choices other than LASIK.
