SAM® Overview
UltraVision
CLPL invented and patented SAM® (Spherical Aberration Management)
technology to improve the power control and inherent quality of all
contact lenses, regardless of material or manufacturing method
employed. The resultant lenses are accurate to the prescribed power
over far more of their area than conventional lenses.
There are major benefits for the wearer, the practitioner and the manufacturer.
SAM® accepts and calculates input from advancing
areas such as wave front technology. In addition to sub-micron
accuracy, SAM® allows for considerations such as the whole lens eye
system, including drape of the lens on eye and non-isotropic
material expansion factors. It also optimises manufacturing
efficiency by taking into account the machining capabilities of the
manufacturing processes used. The system is tailored to increase
calculation orders as new generation manufacturing capabilities,
with tighter tolerances, are developed.
For the patient, many of the benefits of SAM® are clear: the
lenses are clinically superior and offer greater definition and
visual acuity. Flaring is reduced or eliminated, being particularly
apparent to the wearer in low-light conditions. The technology
manages inherent aberrations and controls actual power at all point
of the lens on single-vision, multifocal and toric lenses. It also
allows the lenses to be manufactured thinner, for increased health
and oxygen permeability, without loss of visual acuity, strength or
rigidity.
For the practitioner, in addition to prescribing a superior
lens at no additional cost, there is a significant saving in chair
time. The system facilitates fitting, brings unparalleled confidence
in replacement lenses and minimises initial over refractions.
For the manufacturer, SAM® offers cost savings through
increased reproducibility, reduction of rejects and the automation
of final checking and quality control. The whole system can be put
live into an existing production facility with a one-off set-up time
of just a few hours. In addition, there are the marketing benefits
of offering a more advanced product.
