Attributes

Advanced Optical Design


The Aspheric SeeLens HP was designed using the most advanced tools by a professional R&D team of optical and mechanical engineers.
The optical profile of the SeeLens 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 (Modulated Transfer Function).

 

Eye Model


The Optical design of SeeLens HP 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 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 HP in a post-operative eye.

Geometrical Design


  • SeeLens HP ensures excellent stability and centration due to the unique C-loop mechanical design, ensuring wide angle of contact.
  • 360° square edge in order to minimize PCO.

 

Material

 

The SeeLens HP is made of a hydrophobic material with bio-adhesive characteristics, resulting in reduction of secondary cataract procedures [1].
The SeeLens HP has a very a very low glistening effect [2 3].
The SeeLens HP hydrophobic material incorporates a natural yellow, violet filtering, chromophore for better protection of the retina.
