Centration and rotational stability are integral to achieving optimal postoperative vision results when using multifocal and toric intraocular lenses (IOLs). The introduction of the femtosecond laser for capsulorrhexis has made it possible to create a reproducible capsulorrhexis with predictable diameter and centration. Oculentis has taken advantage of this technology to develop the Femtis IOL, which can be anchored in the perfectly circular capsulorrhexis using four additional specially designed haptics.
With traditional in the bag IOL implantation, capsular shrinkage and fibrosis can increase pressure on the haptics, which can result in decentration, tilt and rotation of the IOL, affecting the optical quality of the visual system. The Femtis IOL design makes it possible to place the lens in the anterior capsule, resulting in improved stability and centration.¹
