Presbyopia surgery or tired eyes
Patients who previously had mild myopia can see up close without glasses for a lifetime as their close focus point remains unchanged. However, patients with farsightedness require correction in both near and far vision. It is these people who experience the greatest dependence on glasses, frequently using progressive or occupational glasses.
What operations for Presbyopia reduce dependence on glasses?
In the case of demanding vision without glasses or contact lenses, correction can be managed by surgery. There is an option to use the laser or intraocular lenses:
The excimer laser technique models the corneal curvature to obtain the desired focus. It is a painless technique since it is performed under anesthesia with drops. There are personalized treatments that increase the focus range or monovision treatments that leave the dominant eye focused for distant vision and the non-dominant eye for near vision. This option can be tested with disposable lenses to study the degree of acceptance of the patient previously.
However, the multifocal intraocular lens implant is more durable since the lens is removed, which is what later becomes a cataract. Therefore, near and far vision can be corrected by gaining eyeglass independence and avoiding the limitation caused by the cataract in the future. It is important to select the right lens for each case and to know the benefits and risks of the technique.
Frequently asked questions about presbyopia or eyestrain:
Is there a way to prevent presbyopia?
Presbyopia is associated with a degenerative process of the lens, so it is not possible to prevent presbyopia. However, people who use corrective glasses less often become less accustomed to them and are therefore less dependent on that use of glasses.
How long does the intervention last?
The introduction of an intraocular lens to replace the lens takes approximately 10 minutes, although it depends on each case.
Is it necessary to have the tired sight stabilized to be able to treat it?
Tired eyesight or presbyopia evolves in all people from approximately 40 to 55 years. If the use of intraocular lenses to correct vision is considered, the most advisable thing is to wait until that age; since it also increases the safety profile of the intervention.
After the presbyopia operation, will I need glasses?
At our center, we surveyed all patients one year after the intervention and satisfaction is highest. Glasses may be required to make a magnifying glass in very small print or in the dark. It may also happen that residual diopters remain or arise over the years, but it is easily adjustable by Laser.
Can be operated with glaucoma?
It is only recommended to operate healthy eyes and that do not have another active disease. In cases of suspected glaucoma, the first thing is to study the optic nerve and visual field to detect if there really is damage and progression. In case this is confirmed, the specific recommendation will be made for the patient considering all his eye and general factors.
Can be operated having previously undergone myopia?
It is a habitual question, since the operated of myopia see well from afar; but at 40 they start to see badly up close and need glasses. They can be operated effectively but they need a more in-depth study since their cornea has been altered and they are not standardized cases. At our center, we have the technology to measure and calculate the best lens using Optical Coherence Tomography and Ray-Tracing. This combination maximizes the chances of success in the intervention.
Are presbyopia and computer use related?
There is no causal relationship between computer use and presbyopia. But it is true that when we have close focus problems, computer work becomes heavier and can even cause headaches. This is because we demand a close focus from the eye that it can no longer maintain. Therefore, it is important to see an ophthalmologist for headaches related to computer use or blurred vision close up at the end of the day.
What are the symptoms of presbyopia?
The most common symptoms of the onset of presbyopia are: difficulty reading small letters, troubles focusing on nearby objects, headaches, eyestrain and having to move both letters and objects away to read them. Those who were nearsighted notice that they see better if they lift their glasses; This is because your eye is no longer able to change focus.
At what age does presbyopia usually appear?
Normally, presbyopia or tired eyesight usually manifests between the ages of 40 and 45. However, there are cases of myopic people who do not perceive the need for glasses close up as they are “outfocus of close-up” or of people who do not use close eyesight in their daily life; and therefore they do not miss it.
