Como consecuencia, disminuye la capacidad de acomodación, lo que dificulta el enfoque de los objetos cercanos.

Con el fin de restaurar la visión de cerca, se han desarrollado e introducido diferentes dispositivos que producen múltiples focos.

Steven Dell, MD, explains that advances in multifocal IOL technology and the release of extended-depth-of-focus lenses has raised the bar for the performance of accommodating IOLs.

In order to achieve that goal, dual-optic accommodating Intraocular Lenses have been designed, whose anterior optic displaces axially to increase ocular power, and focus near objects.

Although dual-optic accommodating IOLs are relatively new, their outcomes are promising, as they provide large amplitudes of accommodation and a greater IOL displacement than single-optic accommodating IOLs.

A piston, activated by the capsular diaphragm, pressurizes a small, rigid chamber containing a silicone gel.

Il y a seulement deux générations, l’ablation d’un cristallin opaque était le seul but de cette chirurgie et l’extraction intracapsulaire du cristallin sans remplacement prothétique a ainsi été pendant plusieurs décennies la technique de référence.

Nos chirurgies modernes associent maintenant la phako émulsification par micro-incision à des implants de plus en plus performants, souples, corrigeant l’astigmatisme et les aberrations optiques.

The chamber is fixated to the eye wall at the ciliary sulcus so that movements along the optical axis are avoided.

The silicone gel is pressurized by forward movements of the capsular diaphragm and depressurized by backward movements of the diaphragm.
