Softec HDY: The Blue-Blocking IOL
The Softec HDY is not currently available for sale in the United States.

Only Lenstec offers the precision and predictability of an aspheric IOL made from unique blue-blocking material proven effective for 20 years.
The Softec HDY is fabricated from a material that has been proven stable, particularly with respect to long term exposure to sunlight, using an accelerated aging study that replicates the equivalent of 20 years of exposure for the average person (based on specific ISO standards for the photostability of IOLs).
So, while the discussion of using blue light absorbers in the fabrication of IOLs has been ongoing since the late 1980s, most researchers would agree that blocking certain wavelengths of visible light is beneficial to the eye… and a material proven to provide stable light transmission properties for 20 years is the obvious choice.

Spherical Aberration and Defocus
- 0.25D of defocus is a more significant aberration than spherical aberration. In fact, 0.25D of defocus is more significant than all higher order aberrations added together.
- Defocus is invariant with pupil diameter - This is not true with spherical aberration which varies with pupil size - small pupils have nearly zero aberration.
