Advanced Optical Design
The Aspheric BunnyLens HP was designed using the most advanced tools by a professional R&D team of optical and mechanical engineers. The optical profile of the BunnyLens HP 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 (Modular Transfer Function)
Eye Model
The Optical design of BunnyLens HP was performed using the advanced 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 aberrations, both on and off axis. The retina curvature is designed to split the tangential and sagittal foci off-axis. The result is an accurate simulation of the visual performance of the BunnyLens HP in the Post- operative eye.

Geometrical Design
- BunnyLens HP ensures excellent stability and centration due to the 4 – point haptic design.
- 360° square edge in order to minimize PCO.
Material
- The BunnyLens HP is made of a hydrophobic material with bio-adhesive characteristics, resulting in reduction of secondary cataract procedures[1].
- The BunnyLens HP has a very low glistening effect[2,3].
- The BunnyLens HP hydrophobic material incorporates a natural yellow, violet filtering, chromophore for better protection of the retina.
