Advanced Optical Design
SeeLens TR is based on Hanita Lenses’ SeeLens AF aspheric IOL. SeeLens 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
T he Optical design of SeeLens 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 SeeLens TR in the Postoperative eye.

Geometrical Design
- SeeLens TR ensures excellent stability and centration due to the unique C-loop mechanical design of the haptics
- 360° square edge in order to minimize PCO.
Material
- The SeeLens TR is made of a hydrophilic acrylic material, with proven reputation and many years of clinical experience
- The SeeLens TR is characterized by excellent biocompatibility and mechanical quality
- The SeeLens TR material incorporates a violet filtering chromophore for better protection of the retina
Stability and Centration
High level of rotational stability is maintained due to the wide angle of contact with the capsular bag.
