Presbyopia or Tired Eyesight appears when the muscle that allows the lens to change its shape and size - which is called the ciliary muscle - stops working. Thanks to this movement of the lens we are able to focus images both near and far. When the muscle in question loses its function we can no longer focus the images correctly. To correct this defect there are only two alternatives: the continued use of glasses that we will have to continually change graduation, or surgery, which will definitively solve the problem.
The intervention lasts about 10 minutes per eye and consists of replacing the lens with an intraocular lens that allows us to focus at different distances. Recovery is very fast and the next day the patient is able to see normally and with little discomfort.
Before surgery, the patient must undergo a series of diagnostic tests that will allow the exact power of the lens to be implanted to replace the lens to be calculated. These are totally innocuous tests in which the patient only has to look at a light. The greatest inconvenience may be that the pupil must be dilated to be able to see the fundus. This will mean that for a few hours the patient may feel some glare.
The most important thing is to go fasting from the night before, including not drinking water.
After completing the admission process, you will access the surgical area. Once there, you will be seen first by the anesthetist, who will place a line to introduce the necessary medication as well as light sedation. Thanks to this sedation, you will remain in a calm state but not completely asleep, since minimal collaboration is required from the patient.
Once it passes to the surgical area, the entire eye area is sterilized, the eye is covered with a cloth and an anesthetic is injected in the form of drops as well as a more powerful one that allows the eye to fall asleep completely and not notice at all. no pain.
The intervention consists of 4 main steps:
As we have already said, the patient is administered different types of anesthetics as well as light sedation. This means that the patient does not suffer any pain. In any case, you may notice a certain sensation of pressure during the intervention, but never pain.
No. Except in exceptional cases, the patient leaves with the eye uncovered. Although the visual quality will not be perfect, it is good enough for the patient to be able to walk out on their own.
Immediately after the intervention, a first control visit is made to verify that the lens is perfectly placed and to make an initial assessment of the patient's visual quality. Obviously, in this first revision the quality will be limited, mainly because the pupil is still dilated.
The only thing that the patient is not allowed to do the same day of the intervention is to drive. This is because it continues with the effects of sedation and it would be dangerous since it can cause drowsiness.
Apart from this, the patient will be able to carry out practically a normal life, although it is recommended that during the first days he does not carry weight.
After surgery there is a period of adaptation. It must be taken into account that the visual system has been modified and this requires some time for us to get used to it. There are many factors that can make this time more or less long: the initial graduation, healing capacity, age... But, in general, after 10-15 days the vision will be practically perfect.
We will be delighted to meet you. Choose day and time.
