What is MPL?







The Medennium Phakic Refrective Lenses (MPL) are precision made optical devices, available in different model/size for intraocular implantation. The optical portion is biconcave or concave-convex and made from sillicon elastomer. The haptics are spherical  and flexible for ease of insertion, and the overall lens shape is designed to conform to the natural shape of the posterior chamber of the human ryr, and to move with the dynamic changes of the eye. Gross centration, if necessary, is achieved via haptic contact with the ciliary sulcus with precise centration achieved through the iris self-centering design. The MPL is not fixed to the ciliary sulcus but is allowed by designed to floating in its self- centered position.


Unique and Safe Design

  • Implantation between iris and crystalline.
  • Natural and precise self-centration by iris.
  • The posterior surface of the lens is designed to conform to the shape of the anterior capsule of the natural lens and to move with dynamic changes of the eye.
  • Spherical and very flexible haptics.
  • Lens is not fixated to the ciliary sulcus.
  • Lens dimensions, shape and material properties enable “floating” on the natural lens without touching it.
  • A layer of aqueous surrounds the MPL, avoiding contact to the crystalline lens and the pigment epithelium of the iris.
  • Overall diameter smaller than sulcus to sulcus distance avoiding compression of intraocular structures.

Monobloc Silicone Polymer

  • Hydrophobic silicone material enables to float over the crystalline.
  • High refractive Index 1.46

Optimized Design Features

  • Rounded edges throughout its entire contour.
  • Maximized optic sizing as large as 6.0mm for powers up to -15.0 diopters.
  • 50% thinner edges (0.1mm) securing the presence of a gap while improving buoyancy.
  • Full spread of powers between -3.0 diopters up to -28.0 in 0.5 increments. By adopting ISO labeling methodology the incremental values were redefined to more accurate levels providing users with smaller increments of refinement between available powers translating into even more accurate final results
