Multifocal implants

Jean-Charles Bauchau

Ophthalmologist

Unlike monofocal implants, which correct only one distance, multifocal implants are designed to provide clear vision at several distances: far vision, intermediate vision (computer, kitchen) and near vision (reading, telephone). Their principle is to use special optics that distribute the light so as to focus the image on the retina at different distances.

The great advantage of these implants is that they reduce or even eliminate dependence on glasses. Once they have been fitted, many patients are able to read, work on a computer and see at a distance without glasses, giving them a great deal of freedom in their daily lives.

However, this technology also has its limits. As the light is spread over several focal lengths, the visual quality is less clear in certain conditions, especially at night. Most patients will also experience halos or glare around lights, for example when driving at night. These phenomena are generally well tolerated, but it is very important to be well informed about them before the operation.

The choice of a multifocal implant must be carefully evaluated on a case-by-case basis, taking into account visual needs, normal activities and the general condition of the eye. When properly indicated, the results are highly satisfactory and allow true visual autonomy.

Implant calculations are based on mathematical formulae with a very low margin of error.

In short, the multifocal implant is a modern, high-performance solution for patients who want to be largely free of glasses after cataract surgery, while at the same time being aware of the risks involved. visual compromises on the quality of vision (especially at night).
