In response, Bonnet claimed that he and Saint-Leg�r L�ger saw " eye to eye ", leading to Phipps, who knew about the state of relations between Bonnet and Saint-Leg�r L�ger, to drily note " in that case the eyes must be astigmatic ".

Lieber, who works as a tool salesman, has been grinding a new mirror for his telescope since 1992 . ( The old one, which was ground by an optician, turned out to be astigmatic . ) " You want to see the Earth turning ? " he asks.

Should the cemented system be positive, then the more powerful lens must be positive; and, according to ( 4 ), to the greater power belongs the weaker dispersive power ( greater v ), that is to say, crown glass; consequently the crown glass must have the greater refractive index for astigmatic and plane images.

One titled " The Festival, " from the book " Vanishing Lung Syndrome, " begins : " At the festival of the patients / with all the known diseases / the crutch choir sings / for the pacemakers . / The double astigmatic landscape / gratefully swallows the murmurs of the mitral valve ."

In 1989 he published a second book Refractive Surgery of the Cornea 22 ( 2 volumes ) with the collaboration of Carmen Barraquer-Coll his daughter, and Alejandro Arciniegas-Castilla, revising his first book as well as describing the lamellar and incisional surgical techniques developed by other ophthalmologists to modify corneal refractive power : Radial and astigmatic keratotomies, epikeratophakia and the first steps on laser refractive procedures.

Beams with elliptical cross-sections, or with waists at different positions in " z " for the two transverse dimensions ( astigmatic beams ) can also be described as Gaussian beams, but with distinct values of " w 0 " and of the " z = 0 " location for the two transverse dimensions " x " and " y ".

Perhaps best known for his work in film scores, Komeda wrote the scores for Roman Polanski s films " Knife in the Water " ( 1962 ), " Astigmatic " ( 1965 ) is widely regarded as one of the most important European jazz albums; British critic Stuart Nicholson describes the album as " marking a shift away from the dominant American approach with the emergence of a specific European aesthetic ."

Manifest refraction is the familiar test where the eye doctor rotates various lenses in front of the eye, asking the patient, " Which is better ( or clearer ), this one or this one ? " Corneal topography is considered a more quantitative test, and for purposes of aligning a toric IOL, most surgeons use a measurement called simulated keratometry ( SimK ), which is calculated by the internal programming of the corneal topography machine, to determine the astigmatic meridian on the surface of the cornea.

He also held U . S . patent number 1, 507, 111 ( September 2, 1924 ) for a new and useful Lens System for Galilean Telescopes . In previous lens systems for Galilean telescopes, the elimination of the image defects was generally confined to the removal of the chromatic longitudinal aberration and the chromatic difference in magnification as well as to the elimination of the astigmatism for a certain definite locus of the eye . But a faultless image outside the axis can only be attained by simultaneously eliminating for the whole telescope the spherical longitudinal aberration and the condition of sine . These requirements were fulfilled by the invention in question, in which the astigmatic difference no longer depended so largely from the locus of the eye, as such has been the case in the Galilean telescopes hitherto known . This was achieved by making the objective consist of two collective members, each of which is composed of two cemented lenses, of which the one having the lower refractive index is facing the incident light, and by composing the ocular of three cemented lenses, the inner one being a flint lens .
