Presbyopia or eyestrain is the difficulty to focus in near vision that appears after the age of 40-45 years. It is a natural and physiological process that affects everyone, appearing 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 prescription needed for distance vision and the characteristics of the eye.
Surgery by implanting multifocal lenses is currently the most commonly used for presbyopia. It consists of replacing the transparent crystalline lens (the eye’s natural lens) with a lens that allows focusing without dependence on glasses for both distance and near vision.
Before surgery, the most suitable lens for the patient is determined depending on the needs and characteristics of the 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, as the safest, most stable, effective and definitive methods, the extraction of transparent crystalline lens with implantation of different intraocular lenses, whether they are multifocal lenses (bifocal/trifocal), monofocal in monovision, or advanced monovision.
In order to perform this type of surgery, the doctors previously perform a detailed analysis of the patient’s needs 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 intervention, one of the advantages of this procedure. The technique is performed through a small incision and recovery is quick. By removing the lens, it also avoids cataract surgery in the future.
