Presbyopia, better known as "tired eyesight", refers to the progressive appearance of difficulty focusing near images (reading, mobile phone, computer monitor ...) when there was no such problem before.
This phenomenon generally occurs after the fourth decade of life, due to the hardening of the lens and the weakening of the muscle responsible for modifying it to produce the approach.
What are the symptoms of Presbyopia?
It usually presents itself with an insidious and progressive beginning, manifesting itself more commonly by difficulty and tiredness in reading, even with occasional double vision ("the letters are mounted on me, doctor ...").
In those patients who did not need optical correction prior to the presentation of the defect, they usually have the glasses known as “up close”, which at the beginning will be of low power and then increase with the passing of the years.
On the other hand, those patients who wore glasses before the arrival of presbyopia will face the inconvenience of having to use different graduations for far and near, either with more than one goggle, with the use of bifocals, progressive glasses or lenses. multifocal contact, all of them with some difficulty adapting according to the patient.
Many patients come to us demanding a solution, even if it involves a surgical procedure, either because of their rejection of glasses, intolerance of contact lenses or simply for improving their quality of life. For them, we frequently use the multifocal intraocular lens implant, which offers acceptable distance and near vision without the use of glasses, reserving for patients with incipient cataracts or associated defects.
Indications of Presbyopic Surgery
People older than 45 / 50 years who are users of glasses from far and near or only near and who want to dispense with their use with a fast and effective refractive treatment.
Before the Presurgical consultation
For CLÍNICA NIVARIA It is of vital importance the direct treatment with each patient who trusts us with their visual health. 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.
- 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 contact lens user, you must do without 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.
After consultation and testing
- 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:
- Informed consent.
- Instructions and recommendations prior to the intervention.
The treatment with multifocal intraocular lens (multifocal vision) consists in removing the lens, which has already lost or is losing its ability to focus closely, and replace it with a multifocal intraocular lens, which acts as an artificial lens. This lens offers different fixed focus planes (far and near distance) and it is the brain that chooses the most appropriate approach for each situation thanks to a procedimiento called pseudoacomodación. In this way, patients recover a full range of vision and can perform all kinds of activities without using glasses or contact lenses, from reading a book to driving. This treatment allows eliminating associated defects and avoids the risk of cataracts.
As a result, the patient will not need glasses or contact lenses for distant vision and will be able to achieve a degree of near vision suitable for everyday life. The treatment is ambulatory and the recovery time is very fast.
Corneal microsurgery The cornea is the transparent and avascular anterior tissue of the eye, which resembles the glass of a clock. The cornea consists of 5 layers: the epithelium, the Bowman membrane, the stroma, the Descemet membrane and the endothelium, the main functions being the protection of intraocular content and reflation
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
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
