Presbyopia is the loss of the ability to focus, so, the eye can no longer change shape to focus on close-up images. . This condition occurs, more frequently, in adults over 40 years.
There are several ways to improve presbyopia, depending on the patient's needs and their age. You can perform the monovision technique (correct one eye for near vision and the other for far vision) with laser or implant multifocal intraocular lenses or the most recent trifocal lenses.
Trifocal lenses are designed to treat cataract and other vision problems such as myopia, hyperopia, and presbyopia, providing a full range of vision, for all distances with greater independence from glasses.
