Oculentis offers a variety of IOL designs. Choose between (a) spherical, 1-piece or 3-piece IOL, IOL with or without blue light filtering technology. The imaging quality of intraocular lenses (IOL) is one of the key factors to ensure an optimal vision for patients after a cataract surgery. Aspherical LENTIS® IOL are characterized by an aberration corrective surface structure. Basis for their design is not as usual a purely spherical cornea but a slightly aspherical cornea (anticipated in the human eye). Studies have shown that the human cornea shows asphericity in respect of the statistical median. Due to this fact, Intraocular lenses, which take into account this aberration, lead to a better visual acuity and better image quality All aspherical LENTIS® lenses are manufactured in the sub-micron lathing process. The square-edge design and the superior surface quality of our HydroSmart® Acrylic reduce the post-surgery-cataract formation and thus the post-treatment rate. A recent study conducted by the Berlin Eye Research Institute (BERI confirms the exceptionally sharp optic edges of the LENTIS® IOL for a better PCO prophylaxis (Study as PDF-Download). All LENTIS® lenses show an excellent biocompatibility and high stability in the capsule bag.
