Cataract is 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 an opaque lens. The greater the loss of transparency of the lens, the more advanced the cataract is.
What are your symptoms?
- Blurred vision, with fog, as through a veil.
- Slow and uneven evolution in both eyes.
- Glare from intense lights or changes in brightness.
- Difficulty at night driving.
- The colors fade, they look differently.
- Double vision with one eye.
- Frequent changes in the graduation of your glasses or lenses.
- A temporary improvement in the sight of people who need glasses to see closely.
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 consultation is essential to perform a correct surgical 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.
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:
• Study of ocular refraction.
• Corneal study.
• Retinal study.
The desirability of performing some other test on special occasions according to optional criteria is not ruled out.
AFTER THE CONSULTATION AND THE TESTS:
After the consultation, if your ophthalmologist sees the convenience of performing the intervention, you can book your appointment for it. In addition, they will indicate the budget of your treatment, as well as the possibilities of financing and you will be given the following documentation:
Instructions and recommendations prior to the intervention.
In addition to these general criteria, the results of all ophthalmological tests performed by the specialist during the preoperative examination will be indispensable to determine if a patient is a good candidate.
Currently, phacoemulsification is the most advanced method for the definitive treatment of cataracts. It consists of the use of ultrasound to dissolve and remove the damaged lens, to replace it with an artificial intraocular lens that is deployed inside the eye without the need to expand the initial opening. This lens performs the same function as the lens, lasts a lifetime and does not lose transparency.
Contrary to popular belief, this intervention is simpler if the cataracts are not formed at all. Once this procedure is done, the patient can go home on his own foot, with the eye uncapped and his visual recovery will be very fast.
It is recommended that the patient remain at home on the day of the intervention. The visual improvement is usually so rapid that the next day you can begin to gradually return to your normal life. However, you should follow some recommendations such as using eye drops, do not rub your eyes and avoid physical efforts such as taking heavy things for a few days after the intervention.
- How can I know if I have cataracts? At first, when the cataract is not very dense, a clouding of the vision is noticed, the lights can also cause more glare than usual. As the cataract develops, the vision becomes more blurred, progressively making everyday activities difficult.
- At what age do cataracts usually appear? Cataracts that alter visual function preventing correct vision with glasses usually appear once 60 is over. However, they can also appear after 50 years. Cataract is more frequent in myopic patients, especially in myopia with high graduations. In these patients, the appearance of cataracts may be earlier.
- Can cataracts and presbyopia or “tired eyesight” be eliminated in the same intervention? Yes. Thanks to the use of multifocal intraocular lenses, when treating cataracts, we can largely correct the “tired sight”.
- Can both eyes be operated at the same time? Currently, thanks to the new protocols for the prevention of postoperative complications, we can perform both eyes at the same time, sequentially.
- Is this operation painful? Absolutely. Currently, the operation is performed, in most cases, with topical anesthesia (drops), without the need for sleep or injections.
- When can I start to live a normal life after surgery? Once both eyes have been operated, the patient can resume normal activity, while being careful not to touch or hit the eye, especially during the first month. Three weeks after surgery, a treatment with eye drops, anti-inflammatories and antibiotics will be maintained.
- Once cataract surgery, can they reappear? No. This is impossible, since the lens affected by the ailment has been replaced by an intraocular lens, however the sac where it is inserted can be opacified, causing a secondary cataract that is treated with a special type of laser.
- Will I need glasses after having surgery? Most patients can perform normal far vision activities without the use of glasses. You will have to wear glasses closely unless you have decided, advised by your ophthalmologist, for multifocal intraocular lenses, which allow you to focus at different distances. However, these lenses are not suitable for all patients, so it requires a personalized study of each case.
