They are used to correct focusing after surgery, such as cataract operations for example, or to eliminate long-sightedness or eyestrain.

Multifocal intraocular lenses offer the patient the possibility of having excellent near, far and medium vision at the same time. The lens of the human eye is equivalent to a 15 diopter lens, such that when an intraocular lens is inserted, care is taken for this to have the same or more diopters than this. They are surgically implanted directly into the eyeball and play the role of the lens, enabling the eye to focus on both near and far objects without the need to use glasses.
