The trifocal/multifocal lens (M-IOL-Tri) is a highly developed artificial lens that has several focal points and thus enables vision at different distances without varifocals and reading glasses. These well-tolerated multifocal lenses can stay in the eye permanently and are not visible. The most modern multifocal lenses are so-called trifocal lenses. With these lenses one can see well in the near, intermediate and far distance. It is also possible to work on a computer without any problems. In addition to presbyopia, artificial lenses can be used to correct nearsightedness, farsightedness and astigmatism.

The insertion of trifocal/multifocal lenses, also known as trifocal/multifocal intraocular lenses, is a safe and precise method of correcting presbyopia. The natural lens of the body is replaced by an artificial lens (multifocal lenses). This refractive lens replacement (RLE) is a highly proven and tested procedure, and has been used for decades in the treatment of cataracts. The surgeon inserts the new lens into the eye with an injector. The lens unfolds and is placed correctly in the empty lens sheath by the surgeon. In addition to presbyopia, the trifocal/multifocal lens can also correct other vision defects such as nearsightedness, farsightedness and astigmatism.

For patients who have already developed presbyopia, which usually becomes noticeable between the ages of 40 and 50. Suddenly the arms are no longer long enough to hold a newspaper or a book far enough away – reading glasses are required. People who are already nearsighted or farsighted in younger years are also affected by presbyopia over the years.

Trifocal/multifocal intraocular lenses (M-IOL) distribute the incident light over several focal points, enabling sharp vision for reading, far distance and intermediate distance.

Trifocal / multifocal artificial lenses lead to a certain reduction of the image contrast. Therefore, at dusk, halos around light sources are often described. On the other hand, our brain learns to adapt to these changes so that they are usually no longer perceived after a short time.
