Since its introduction in 1990, more than ten million people have solved their visual problem with excimer laser.
Yes, it can. The LASIK technique allows correcting myopia or hyperopia with astigmatism in the same procedure by modifying the curvature of the cornea, therefore myopia or hyperopia with astigmatism is eliminated at the same time.
Normally you can wear make up on your eyes one week after the procedure.
Currently, the limits are approximately 12 diopters for the myopic and 6 for the hyperopic and astigmatic. Nevertheless, these limits may vary depending on the characteristics of the eye.
If the intervention is performed with a stabilized prescription, the refractive problem does not usually reappear ever again. Just a small percentage of people may need additional surgery.
The intervention is very fast, just a few minutes depending on the prescription that is going to be corrected. It does not require previous preparation, and after 30 minutes, after a brief rest and a first postoperative evaluation, the patient can leave the clinic unaided.
Absolutely not. Occasionally it can cause minor discomfort similar to the one caused by a speck of dust or slight pressure in the eye. Anaesthetic drops are applied on the cornea so the patient feels nothing during the intervention.
It is necessary to understand that, since it is a microsurgery operation, the patient should not perform head and body movements. However, during the laser application phase, the system has an eye-tracker that corrects minimal eye movements. During the thirty seconds that the laser application takes, the position of the eye is verified 200 times per second, making sure that it is in place and the treatment is performed properly. Any slight eye movement is detected and compensated by this system at a rate of a thousandths of a second.
In some cases, less than 10%, a minor residual prescription is left after the operation which is eliminated in a second intervention that is normally carried out approximately three months later.
Technology in ophthalmology evolves very quickly and only the clinics with capacity to reinvest in the purchase of new equipment can be updated. In Dr. Tirado's Eye Clinic we have the Allegreto Eye-Q 400 laser that performs personalized treatments for wavefront and asphericity modifications and the femfoseaser laser or femtolaser, which allows to perform 100% of the surgical process with laser, without needing to use scalpels or blades. They are approved by both the US FDA and the European Union.
The LASIK and LASEK / PRK procedures require very little postoperative medication due to their simplicity: eye drops and artificial tears that should be used for a short period of time.
A medical checkup is scheduled: 1st 24 hours after; 2nd A week after; 3rd A month after; 4th 3 months after which is the last control and definitive medical discharge is given. After LASIK surgery, the patient can leave the clinic without the need of any aid, with slightly irritated and/ or watery eyes, but with enough vision to be able to move. On the next day you will see much better and, depending on the error treated and its magnitude, the visual recovery will be progressive, in days. Usually, patients undergoing LASIK, on ​​the day after the intervention, will be able to perform normal tasks such as personal hygiene, eat, walk, and even read and watch television. From this moment onwards, the recovery will be progressive, until reaching the appropriate vision. After LASEK or PRK surgery, the patient can leave the clinic without the need of any aid, with slightly irritated and/ or watery eyes and even with some discomfort (therapeutic contact lens, adapted by the ophthalmologist, will have to be worn) and with enough vision to be able to walk around and move. On the next day you will see much better and, depending on the error treated and its magnitude, the visual recovery will be progressive, in days (although it will be from the withdrawal of the contact lens - matter that will be indicated by the doctor when the improvement begins). Usually, the patients who undergo LASEK / PRK are able to perform normal tasks such as cleaning, eating, walking, and even reading and watching television on the day after the intervention. The adequate functional recovery of vision will arise as the days pass. Let´s recall that, as in all human interventions, as time or days pass and with a normal physiological process of recovery, it will be possible to achieve the visual capacity appropriate to the case.
Visual recovery is usually very fast after LASIK. It´s practically a matter of hours the time it takes to be able to return to normal activity. In most cases the next day. Although the best results and complete stability, should be expected after a week; Nevertheless, in some cases, the above mentioned objective is reached during the first month. The visual recovery process is slightly longer in LASEK / PRK. However, we must take each patient´s individual factor into account - individualized reaction - that will have a significant influence on the entire process. It is important not to forget that even though the intervention is very simple and non-invasive it is still an operation, and as such, postoperative care, even if minimal, and recovery time are essential.
In the event of having your case personally studied previously and not being able to go for LASIK due to the high prescription, the alternative would be intraocular refractive surgery.
You cannot. You must wait until the pregnancy is over. During pregnancy prescriptions might vary.
Although it is an extraocular and outpatient intervention, we should not forget that it is surgery, therefore, a certain low level of risk exists. For this reason, the preoperative medical consultation becomes extremely important, since it allows the ophthalmologist to establish the precise medical criteria that avoids taking unnecessary risks. In Eye Clinic Dr. Tirado, about 15% of the patients who go through consultation are considered to be " unsuitable ". Assuming that we ensure a thorough preoperative study, you can rest assured that if you are not suitable to undergo laser surgery, we will explain why and study other options. In these cases, we propose alternative surgical non laser treatments, or just explain the need to continue wearing glasses and / or contact lenses. All together, the indication, alternatives, intervention, and complications will be clarified in detail by the ophthalmologist throughout the appointment. The ophthalmologist will be available for the patient to clarify any doubts that may arise.
You cannot rub your eyes during the first week, so it is important to avoid any action that can lead to it: soap in your eyes, sand in your eyes, etc. And during the following 4 weeks try to rub your eyes as least as possible.
If you cannot contact the consultation at 952 58 08 17, you must call your surgeon´s personal emergency number which is provided in the preoperative instructions.
