Presbyopia or eyestrain is the difficulty to focus on near vision that appears from 40-45 years. It is a natural and physiological process that affects all people, manifesting sooner or later depending on the case.
For the correction of presbyopia there are different techniques selected for each case, depending on the age of the person, the graduation needed for far vision and the characteristics of the eye.
The surgery by implanting multifocal lenses is currently the most used for presbyopia. It consists of the replacement of the transparent lens (natural lens of the eye) by a lens that allows to focus without dependence on glasses both in far vision and near vision.
Before the intervention, the most suitable lens for the patient is determined depending on the needs and characteristics of his eye.
Multifocal or monofocal lenses
Although presbyopia can be corrected with different techniques, at the Institut de la Màcula i de la Retina we recommend, because it is the safest, most stable, effective and definitive method , the extraction of transparent crystalline lens with implant of different intraocular lenses, either lenses multifocal (bifocal / trifocal), monofocal in monovision, or advanced monovision.
To perform this type of surgery, previously the doctors perform a detailed analysis of the needs of the patient before resorting to the intervention, in order to decide the technique and the most appropriate intraocular lens in each case.
As for the recovery of this type of interventions, one of the advantages of this procedure. The technique is performed by small incision and recovery is quick. By removing the lens, it also prevents cataract surgery in the future.
