Frequently asked questions
HOW DO I KNOW IF I’M A GOOD CANDIDATE FOR LASIK SURGERY?
Most people in their 20s, 30s or early 40s, with healthy eyes, adequate cornea thickness and that haven´t had any significant changes in their lens prescription during the past year, can be considered good candidates for this procedure.
At Okumed we pay very close attention to all of these details, that is why due to our ethics, profesionalism, experience and honesty in the candidate selection process, we have achieved more than 99% of success rate in the lasik surgeries performed.
WHAT IF I WEAR CONTACT LENSES?
If you wear contact lenses, it is a good idea to stop wearing them before your baseline evaluation and switch to wearing your glasses full-time (1 weeks for soft lenses, 2 weeks if you wear hard ones). Contact lenses change the shape of your cornea for up to several weeks after you have stopped using them depending on the type of contact lenses you wear. Not leaving your contact lenses out long enough for your cornea to assume its natural shape before surgery can have negative consequences, such as inaccurate measurements and a poor surgical plan, resulting in poor vision after surgery.
IS THERE AN RISK FOR SURGERY IF I’M PREGNANT?
Since hormones change significantly during pregnancy and breast feeding (these fluctuations alter the corneaÃÂ´s shape), it is recommended to wait at least 6 months after these stages to have the evaluation and surgery performed.
ARE THERE ANY RISKS DURING THE SURGERY?
The risk reduction depends greatly on the adequate selection of candidates and the technique chosen for the surgery. Thanks to state of the art technology and the use of safe and highly reliable tools there is practically no possibility of loss of vision due to the surgery: the Intralase offers a total control over the flap creation and the laser has an eye movement sensor that automatically stops if it moves beyond the established limits.
The only risks a patient faces when undergoing this surgery are:
1. Not getting a perfect 20/20 vision at the end. In most cases, the residual graduation can be corrected with a touch-up surgery.
2. Dry eyes. This can be solved with lubricant or artificial tear eye-drops.
WHAT HAPPENS DURING SURGERY?
Before the surgery, a nurse will clean your eye area with a cotton ball and will apply antibiotic and anesthesia drops so you wonÃÂ´t have pain during the procedure.
Afterwards you`ll be taken to the surgery room and will be asked to lie down in a special reclining bed. A small tool will be used to separate your lids and help you keep your eyes open. With Intralase, you will be asked to follow a light beam while the flap with is being created. With Lasik, the doctor will place a metallic ring over your eye and proceed to create the flap using a special blade called microqueratome. You will experience some seconds of total darkness and feel some pressure at this point, but no pain at all. After that you will see the light again.
Once the flap has been created and lifted, the doctor will ask you to stare directly at the flashing red light until the laser application has been completed. The laser has an eye-movement sensor that follows the eye and stops automatically in case it is moving too much.
When the laser is done the doctor will place the flap in its original position, will remove the eyelid separator and apply antibiotic drops.
At last the nurse will place protecting shields over your eyes (you will not take them off until the next day and then will use them only at night, during one month, to avoid any possible rubbing while you are sleeping) and will give you some instructions.
About an hour later, the anesthesia effect will start to fade away and you will feel a tingling sensation on your eyes. This feeling will last for about 2 hours, so we strongly recommend you rest and take a nap after the surgery. At this point, the only thing you CAN NOT do is squeeze or rub your eyes, because this can make the flap move and can cause several problems.
The rapidness of the recovery process depends on each person. Most patients experience 90% of the recovery during the first 24 hours, which allows them to go back to their normal activities by the second day.
We recommend that from now on, you use sunglasses and lubricant eye drops. Also you will have to avoid the following activities after the surgery:
No squeezing or rubbing your eyes (1 week)
Avoid getting water in your eyes while taking a shower (1 week)
No swimming (1 month)
Avoid closed areas with smoke (1 week)
No eye makeup: mascara, eye shadow, eye liner, etc (1 week)
HOW IS A PERSON'S VISION AFTER LASIK SURGERY?
Approximately 9 out of 10 people (90%) who undergo LASIK result in vision between 20/20 and 20/40, without glasses or contact lenses.
