The Maxim scleral rigid gas permeable lens
is a revolutionary new design in
contact lenses that offers excellent acuity for both the normal and abnormal
cornea. A soft lens feels comfortable because of its large size and the fact
that it moves very little during blinking, not because of its soft material.
Since the Maxim Lens is comparable in diameter to a soft lens and has minimal
movement, it is also extremely comfortable; however, the Maxim Lens
distinct advantages over a soft lens. It has a Dk value (measurement of oxygen
transmissibility) of 147, higher than many soft contacts. And because it vaults
over the cornea, there exists a fluid interface between the lens and the cornea
that provides considerable comfort to anyone wearing this lens, particularly to
those suffering from dry eyes.
The Maxim Lens provides a new refractive surface to the eye when the cornea
has irregularities arising from pathology, such as keratoconus (below as
shown by the red demarcated area) and pellucid
marginal degeneration, as well as other conditions that alter its normal shape.
The DAC lathe
, considered to have one of the most advanced
this modality, is used to robotically
create each lens. Proprietary curves are
generated on the back surface of the lens to achieve maximal comfort and fit,
while the front surface is used for carving spherical and cylindrical powers
(the refraction) to provide excellent acuity.
