Crystalline lens parameters in infancy
Ophthalmic and Physiological Optics, 1996SummaryDespite the importance of lens power to ocular development, few data are available regarding infant crystalline lens parameters. Lens and corneal radii of curvature were measured in the horizontal meridian using a video‐based keratophakometer, and refractive error was measured by cycloplegic retinoscopy in 19 out of 27 infants ranging in age ...

THE PROBLEM OF THE CRYSTALLINE LENS
Archives of Ophthalmology, 1935Herbert Spencer in his "Principles of Biology" said: "There can be no knowledge of function without a knowledge of some structure to perform function." To no other part of the human organism is this more applicable than to the crystalline lens, for there is no other anatomic structure that is more mathematical in form than the lens or so complex in ...

Crystalline Lens Power in Myopia
Optometry and Vision Science, 1992Growth of the eye shows a coordinated pattern whereby the reduction in refractive power of the cornea and crystalline lens tends to reduce the myopia that would otherwise result from the normal increase in axial length. There is some controversy as to whether the reduction in crystalline lens power is influenced by the refractive state of the eye, i.e.,

Luxation of the Crystalline Lens in the Dog*
Journal of Small Animal Practice, 1969SUMMARYLuxation of the crystalline lens is a heritable defect in the dog and is virtually confined to a small group of terrier breeds.The condition is usually bilateral, although both eyes are not necessarily affected simultaneously. The lens may subluxate or dislocate, usually into the anterior chamber.Secondary glaucoma follows and leads to ...

GLUTATHIONE IN THE CRYSTALLINE LENS
Archives of Ophthalmology, 1929The soluble portion of the lens protein has been the subject of considerable interest and study since the time of Moerner, 1 who showed that it was composed almost entirely of the two crystallines which represented in great part the sulphur content. The nitroprusside reaction, which was described by Arnold 2 in 1911, showed that the normal lens when ...

Analysis of crystalline lens position
Journal of Cataract and Refractive Surgery, 2006To study normal crystalline lens position to provide a comparative baseline for future studies of crystalline lens or intraocular lens shift.Taipei Municipal Yang-Ming Hospital, Taipei, Taiwan.A Scheimpflug anterior segment analyzer (EAS-1000, Nidek) was prospectively applied to measure the cycloplegic crystalline lens position in subjects who had not ...

The eye is the main organ for sensing light, and its design is optimized for capturing light and forming images. The eye is, in many respects, like a camera. The optical system of the eye forms an image on the retina, whereas the camera lens forms its image on film. The camera must be focused by changing the distance from the lens to the film. However,

Management of the subluxated crystalline lens
Journal of Cataract and Refractive Surgery, 2013The surgical management of ectopia lentis presents the ophthalmic surgeon with numerous challenges and options. From the clinical evaluation to the surgical approach, ectopia lentis patients require additional methodologies, techniques, and devices to ensure the best possible outcome.
