Advanced Optical Design

BunnyLens TR is based on Hanita Lenses’ BunnyLens AF aspheric IOL. BunnyLens TR was designed using the most advanced technology by the professional R&D team of optical and mechanical engineers. The optical profile algorithm of the lens 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 TR 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, providing an optimal platform for correction of toric aberration. The result is an accurate simulation of the visual performance of the BunnyLens TR in the Postoperative eye.
