Intraocular lens surgery
The phakic lens is an intraocular lens that is added to the eye's optical system without removing any structure. This lens allows the eye to properly focus light rays on the retina. These lenses can correct high diopters in myopia, farsightedness and astigmatism.
Intraocular lens implants respecting the natural lens have become an increasingly used alternative when the correction of myopia or farsightedness cannot be achieved by laser corneal surgery. The surgical procedure is performed on an outpatient basis and with local anesthesia.
Phakic lenses are used when diopters are moderate or high (myopia greater than 10 D and farsightedness greater than 5 D). The laser corrects well the low and moderate defects but when they are high it is better to resort to phakic lenses since from the point of view of visual quality the result is superior. They are also used when diopters are low but for different reasons the laser technique cannot be applied (fine cornea or irregularity). Finally, phakic lenses are indicated when there is a significant dryness in the eye.
For the NIVARIA CLINIC, direct treatment with each patient who trusts us with their visual health is of vital importance. That is why the entire pre and post-surgical process is performed by the same ophthalmologist surgeon who will perform the intervention.
If you are interested in this type of surgery, the first step is to request a pre-surgical consultation. This query is essential to be able to make a correct indication. Below we inform you what they consist of.
BEFORE THE PREQUIRURGICAL CONSULTATION:
IMPORTANT: It is very important that when you book your appointment by phone (822 027 777) you indicate that you want to have a pre-surgical consultation or general pre-surgical exam.
If you are a user of contact lenses, you must do without them at least ONE WEEK in advance, so that the results of the tests performed are as reliable as necessary.
We advise you to come accompanied, since during the tests the pupil will dilate and this will make it look blurry for a few hours. It is not advisable to drive after the tests for the same reason.
PRIOR GENERAL EXAM:
In addition to the consultation, a series of ophthalmological and optometric tests will be carried out to determine whether or not to perform the intervention, as well as the most appropriate type of surgical technique for each particular case. These tests are:
• Refraction with and without pupil dilation.
• Corneal study.
• Retinography / retinal OCT.
The desirability of performing some other test on special occasions according to optional criteria is not ruled out.
If you would like more information on the General Exam tests, we invite you to consult the following information collected in our BLOG: GENERAL EXAMINATION FOR REFRACTIVE SURGERY.
AFTER THE CONSULTATION AND THE TESTS:
The results of all these tests allow the ophthalmologist to determine whether a patient is an optimal candidate or not to perform this type of intervention, or a different surgical technique must be proposed to solve his refractive problem.
When booking an appointment for the intervention, in addition to indicating the budget for your treatment, as well as the financing possibilities, the following documentation will be delivered:
Instructions and recommendations prior to the intervention.
To make sure the procedure is painless, the surgeon will apply a local anesthetic to the eye, which means that you are probably awake
during the procedure; They may also provide something to help you relax.
During phakic surgery, the doctor makes a small incision in the eye, and the lens is inserted with a special injector, which allows it to unfold smoothly. The incision is so small that it does not require stitches.
- Since when do phakic lenses exist? The first models were those of Iridian support in the decade of the 60 and later the epicapsular (ICL) at the beginning of the 90. Therefore there is a proven experience worldwide of this type of lens.
- Do you see phakic lenses from outside? Phakic lenses are very small in size and transparent, so they cannot be seen in normal conditions.
- Do the lenses break down or become dirty? Phakic lenses are made of materials so biocompatible that their composition does not change over the years.
- Do phakic lenses inside the eye cause discomfort? No, phakic lenses do not feel or bother inside the eye. They are not sutured to any ocular structure or move inside the eye.
- How long can a phakic lens in the eye last? They can last a lifetime. However, the patient's eyes due to natural causes and evolution can change and develop new situations, for example cataracts. The lenses can be explanted and the new problem treated.
Different refractive defects such as myopia, hypertherotopia and ASTIGMATISM, so far corrected only through the use of glasses or contact lenses, with the corresponding limitation in the quality of daily life, hobbies, work, etc. of its users, now have the development of the Excimer Laser technique that allows such correction, offering the
Cataracts Cataracts are the loss of transparency of the lens. The lens is a lens that we have behind the pupil and that helps us sharply focus on the objects. Due to a series of circumstances, diseases or more frequently due to the passing of the years, the lens may lose its natural transparency and become
