Lens Development: Fiber Elongation and Lens Orientation
Science, 1963When the lens of the 5-day chick embryo is surgically reversed so that its epithelium faces the neural retina the elongation of those lens cells which have already differentiated is arrested and the epithelial cells differentiate into a new set of lens fibers.

Ophthalmic and Physiological Optics, 1982
Abstract Theory is derived for the calculation of the volume of type‐ and barrel‐form torie lenses. The integral produced is evaluated using an approximate method of integration. Differences between the two volumes are considered insignificant in the corner of spectacle lens manufacture.

Intraocular lens power calculation for lens exchange
Journal of Cataract and Refractive Surgery, 2001To examine patients who had intraocular lens (IOL) exchange for large postoperative refractive errors and determine the factors that contributed to the error in IOL power calculation.Thirteen affiliated hospitals in Japan.This study comprised 34 cases that required IOL exchange because of large refractive errors after primary lens implantation ...

Refractive lens exchange with a multifocal intraocular lens
Current Opinion in Ophthalmology, 2003Refractive lens exchange with a multifocal intraocular lens is becoming a more popular method of refractive surgery in the presbyopic patient. The limitations of keratorefractive surgery have led to a resurgence of lens exchange surgery for patients with prescriptions outside the limits of corneal refractive procedures, in addition to patients with ...

Zoom Lens with Aspherical Lens for Camcorder
International Lens Design, 1990Recent optical systems consist of spherical lens elements, because the spherical lens is suited for productin and the surface inspection. But now as the precision production and mass production technologies are developed, there are many lens systems with aspherical lens elements for still camera and projection TV.

Abstract This chapter presents variants of Brunswik’s lens model aimed to understand whether, when, and why trait judgments are more or less accurate. After outlining the basic concepts of lens models, it describes exemplary studies that have applied the lens model to unravel personality expression and impression formation processes that
