Textbook of Ophthalmology
The lens needs to move or translate for proper vision.37 There are 2 types of
RGP bifocals commonly in use today: aspheric and translating. Aspheric bifocals
uses simultaneous vision and is best suited for the early presbyope, especially

Manual of Contact Lens Prescribing and Fitting
The Aspheric from Correctech, Inc (I-Kon) has a front aspheric surface as well to
negate the aspheric optics so it behaves optically like a spherical lens. It comes
in three diameters: 8.8/9.6/10.4 D. Multi-Aspheric lenses have evolved in order to

Mastering Refractive IOLs: The Art and Science
Another possible problem with aspheric lOLs is the amount of flattening required
by the aspheric design. This could produce an anterior surface much flatter than
that of a spherical IOL, especially with high refractive index material and low- ...
Introduction A space is said to be aspheric if all its homotopy groups of order
higher than 1 vanish. A knot K (of multiplicity ^1) imbedded in the 3-sphere S3 is
said to be aspheric if Sz — K is aspheric. The object of this paper is to prove that

30 25 20 10 15 6.4 Decentration/Tilt of Aspheric IOL An obvious concern with
wavefront-modified IOLs is the required accuracy of the centration of the lens.
The primary aberration introduced by decentration of an IOL with positive or
Thomas Kohnen, Douglas D. Koch, 2008
The cornea is aspheric, but not in a continuously symmetric fashion. The
asphericity of the contact lens will vary in each meridian, consistent with the
corneal astigmatism (CA). An aspheric lens would be a preferred design for low
cylinders, but ...
International Trends in Applied Optics
The Schneider ALG 200 machine will grind and center an aspheric surface in
less than 30 minutes. The integrated software and onboard tool changer allow
the use of multiple spindles to rough- grind, fine-grind, and prepolish the aspheric
Arthur Henry Guenther, 2002
The Optician Training Manual
An aspheric lens, in the technical sense, is any lens that incorporates various
curvatures as opposed to a uniform curve throughout the lens. “A” as a prefix
means “not,” and “spheric” means symmetrically curved. Therefore, an aspheric
lens is ...
Advanced Ceramic Technologies & Products
Optical lenses are classified into two types: spherical lenses and aspheric lenses.
Spherical lenses have been produced for a long time by polishing optical glass.
The mass production of glass aspheric lenses began in the 1980s following the ...
