OBJECTIVE To describe patterns of vision care among Medicaid-enrolled children. METHODS We evaluated claims data over a 1-year period among children who were 18 years and younger, living in Michigan, and continuously enrolled in Medicaid but did not have a complex medical condition or were disabled. For this study, vision care comprised eye care services provided by optometrists or ophthalmol...

PURPOSE To describe the results of lens-sparing vitrectomy for the correction of retinal detachment associated with retinopathy of prematurity (ROP) and its associated complications. METHODS Seventeen patients who underwent a lens-sparing vitrectomy for stage 4 and stage 5 ROP with plus disease at Seoul National University Children' s Hospital between 1999 and 2003 were enrolled in this study...

PURPOSE To compare the long-term results (9 years) of LASIK in one eye and phakic intraocular lens (implantable contact lens [ICL]) implantation in the fellow eye of the same patient. METHODS A patient with high myopia underwent LASIK with a MEL 60 excimer laser in one eye (spherical equivalent refraction -9.75 diopters [D], 5-mm optical zone with no transition zone) and phakic intraocular le...

PURPOSE The purpose of this study was to examine the ontogeny and phylogeny of lens growth in a variety of species using allometry. METHODS Data on the accumulation of wet and/or dry lens weight as a function of bodyweight were obtained for 40 species and subjected to allometric analysis to examine ontogenic growth and compaction. Allometric analysis was also used to compare the maximum adult...

A Cataract, is an opacity within a lens. Out of various eye disorders CATARACT “Clouding of eye lens” is a major problem encountered in canines, and ophthalmic surgery offers great potential for relief of distress and improvement of quality of life. Like a camera eyes have a clear lens inside them that is used for focusing the light. Surgical removal of cataract is a treatment of choice, if res...

INTRODUCTION There are various reasons for the lens dislocation. Spontaneous dislocation of a clear lens is extremely rare, especially its dislocation to the anterior chamber. CASE OUTLINE The author presents a case of spontaneous clear lens dislocation to the anterior chamber in both eyes in a patient without the history of any trauma. Dislocation occurred spontaneously, first in the left ey...

PURPOSE The mouse eye has potential to become an important model for studies on the genetic control of eye growth and myopia. However, no data are published on the development of its optical properties. We developed a paraxial schematic model of the growing eye for the most common laboratory mouse strain, the C57BL/6 mouse, for the age range between 22 and 100 days. METHODS Refractive develop...

The refracting power of the eye results from the static power of the eye (the combined ability of the cornea and the lens to bend incoming rays of light) and the accommodative power of the eye (the variable force of accommodation that alters the path of light rays by causing the ciliary body to change the curvature of the lens). The total increase in plus power that accommodation produces is kn...

This study confirms Leonardo's claim to have experimented on the bovine eye to determine the internal anatomy of the eye. The experiment, as described by Leonardo, was repeated in our laboratory. The study further discusses Leonardo's primary interest in the study of the eye (especially the lens), to determine how the image of an object which enters the eye in an inverted form is righted. The s...

We describe a technique for femtosecond laser-assisted bag-in-the-lens (BIL) intraocular lens (IOL) implantation. Anterior capsulotomy and lens division into small pieces are performed by the laser. A fluid-filled interface makes it possible to re-dock the laser to the eye for posterior capsulotomy after the eye has been opened for lens aspiration without complications. The integrated optical c...
