Advanced Optical Design


The Aspheric SeeLens AF was designed using the most advanced tools by a professional R&D team of optical and mechanical engineers.
The optical profile of the SeeLens AF 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 SeeLens AF 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 SeeLens AF in the Post- operative eye.

Geometrical Design


  • SeeLens AF 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 AF is made of a hydrophilic acrylic material, with proven reputation and many years of clinical experience.
  • The SeeLens AF is characterized by excellent biocompatibility and mechanical quality.
  • The SeeLens AF material incorporates a natural yellow, violet filtering, chromophore for better protection of the retina.
