POSTERIOR CHAMBER INTRAOCULAR LENS IMPLANTATION IN THE ABSENCE OF POSTERIOR CAPSULAR SUPPORT

引用

Eye Science 1989年第Z1期14卷 19-23页

作者： Walter J.(stark) Gerri Goodman Daniel Goodman John Gottsch Wilmer Ophthalmological Institute Johns Hopkins University School of Medicine Baltimore Maryland U. S. A

Because of the high incidence and great variety of complications associated with anterior chamber intraocular lenses, we have developed a technique for the implantation of a posterior chamber intraocular lens in the absence of posterior capsular suport. The posterion chamber ■ is placed in the ciliary sulcus hy suturing the superior haptic to the iris and the inferior haptic to the sclera at the ciliary sulcus. We have used this technique successfully in both compheated extranapsular surgery and se-

Charles Sheeler＇s Paragone： Literary Influence and the Shaping of a Hierarchy

引用

Journal of Literature and Art Studies 2016年第3期6卷 226-234页

作者： Heather L. (stark) Marshall University Huntington USA

This study is concerned with the literary and aesthetic influences that led to Charles Sheeler＇s formation of a paragone in his early 20th century work. This painter, photographer, printmaker, and experimental filmmaker had very specific ideas concerning the hierarchy of the visual arts. While he is known for embracing a wide range of media and materials, by 1919 his aesthetic thought reveals a desire to elevate the painting over all other media. This formation of a visual paragone was initially influenced by his involvement in the interdisciplinary circles which surrounded both Alfred Stieglitz and Walter and Louise Arensberg in New York City. In particular, his lifelong friendship with the poet and writer William Carlos Williams would shape his aesthetic thought leading to his elevation of painting over all other media. Sheeler＇s paragone would begin to form during his stays at the rural Doylestown House in Bucks County, Pennsylvania. This rural home, which he first rented with fellow painter Morton Schamberg in 1916, would become an artistic refuge for both artists. While commercial photography was beginning to take up more if his time in Philadelphia, it was the retreats to the Doylestown house that enabled Sheeler to continue experiments in painting and begin to think of the photograph as something other than a document of architectural work. At this early stage in his artistic career, Sheeler was beginning to form his own hierarchy and contribute to the continuing argument of painting versus photography.
