Precision Profile Design™ was developed by Alcon Inc. and introduced in 2009.
Precision Profile Design™ is a combination of three lens design features:
- A bi-aspheric surface
- An adaptive minus power profile
- A center-near design
These three work together with the goal to deliver clear vision and smooth uninterrupted transitions from near to intermediate to distance vision.
The aspheric front-surface design was introduced to enhance image quality and contrast. The aspheric back-surface supports lens centration and fit across a wide range of corneal curvatures. The adaptive minus-power profile minimizes aberrations and with additional minus-power at the periphery of the optic zone, the plus-powers can be further 'pushed' for distance vision. This helps to improve near vision without compromising distance vision.
