Astigmatism Lens

The Minolta Maxxum Autofocus Lens System is one of the world's most complete lens systems, covering every kind of lens from wideangle, telephoto, and wide-range zooms to large-aperture, reflex, and soft focus types. Only Minolta Maxxum AF lenses are expressly made to link perfectly with your Minolta Maxxum AF SLR. Every Maxxum AF lens locks into your Minolta camera to form an integrated unit that allows focus and exposure data to flow from the lens' read-only memory (ROM) integrated circuit to the camera's central processing unit. The 24-105mm zoom works on both Maxxum film SLRs and Maxxum digital SLRs. On digital SLRs, the focal length is increased by 50%. The lens will provide coverage equal to a 36mm-157.50mm lens.Each Maxxum AF lens is a product of Minolta's advanced computer-assisted optical design. Minolta is one of the few camera makers who insist on making our own optical glass. Our uncompromising quality control in every aspect of the lens-making craft assures you of the finest performance.

Surgeons must meet the challenges of understanding and implementing the new technology for pseudophakia if they are to ride the coming demographic tidal wave of baby boomers desiring excellent vision without relying on spectacles. Refractive Lens Surgery represents a compilation of the best cutting edge practices for achieving success with refractive lens exchange. From mastering biometry and lens power calculations in eyes that have had prior keratorefractive surgery to learning the latest micro incision lens extraction techniques, this well known group of authors will take you step by step into the exciting new world of intraocular lens technology. Refractive Lens Surgery will serve as both a text book and a reference guide to this exciting and rapidly growing segment of ophthalmology, an invaluable resource that makes sense of the myriad new developments in this field.

Corrective lens - A corrective lens is a lens worn on or before the eye, used to treat myopia, hypermetropia, astigmatism, and presbyopia. The most common types of corrective lenses are spectacle lenses and contact lenses.

Astigmatism - In optics, astigmatism is a monochromatic aberration in which an optical system has different focal planes for rays in different planes. Lenses and mirrors which are partly cylindrical show this behaviour already for on-axis rays, parabolic mirrors and uncorrected lens systems only proportional to the squared angle between rays and optical axis.

Thin lens - In optics, a thin lens is a lens with a thickness (distance along the optical axis between the two surfaces of the lens) that is negligible compared to the focal length of the lens. If the thickness of the lens is not neglected, it is called a thick lens.

Bifocals - Bifocals are eyeglasses that have corrective lenses containing two different lens powers. They are most commonly prescribed for people with presbyopia, and who also require a distance correction for myopia, hyperopia, and astigmatism.
