Hanita Lenses - Model HP Easy -Preloaded Hydrophobic IOL System
Advanced Optical Design; The Aspheric HP lenses were designed using the most advanced tools by a professional R&D team of optical and mechanical engineers. The optical profile of the HP lenses was calculated using ZEMAX™ software – a simulating tool for the optical design optimization. Calculations were aimed to minimize all aberrations, including the spherical aberration of the cornea, and to optimize the MTF (Modulated Transfer Function).
Eye Model
The optical design of the HP lenses was performed using the Arizona Eye Model[1].
The parameters and dimensions of the eye model are consistent with average human data. The model was designed to match clinical levels of aberration, both on and off axis. The result is an accurate simulation of the visual performance of the HP lense in a post-operative eye.

Geometrical Design
Both platforms of the HP lenses ensure excellent stability and centration due to the carefully designed geometry, ensuring wide angle of contact and perfect anatomical stability over time. 360° square edge in order to minimize PCO.
Material
The HP lenses are made of an aliphatic hydrophobic material resulting with a very low glistening effect[1,2 ].
The HP hydrophobic material incorporates a natural yellow, violet filtering, chromophore for better protection of the retina.
