Current Opinion in Ophthalmology, 1993
Cataract remains a major source of blindness in many countries throughout the world. Although modern medicine and technology have combined to provide an almost ideal solution, availability of modern cataract and lens implant surgery is restricted, even in developed nations. The health care "cake" is not always divided fairly in favor of ophthalmology

Current Opinion in Ophthalmology, 2002
Since Zaldivar's review of phakic intraocular lenses in these pages in 2000 [1**], further reports of experience with this technology have emerged. Their relative advantages and disadvantages over competing technologies are becoming clearer. Clinical trials, including Food & Drug Administration (FDA) trials, have shown predictability, stability, and ...

I have again reviewed the current state of the art in intraocular lens design in what has been a year of consolidation rather than dramatic discoveries. In foldable lenses, silicone reigns supreme, but there is the promising development of high-refractive-index foldable acrylic lenses.

Birefringence of intraocular lenses
Journal of Cataract and Refractive Surgery, 2004To determine the polarization properties of intraocular lenses (IOLs) in vitro and whether these properties contribute to significant intraindividual differences in the optical performance of the eye, including retinal imaging.Tokyo Medical University, Shinjuku, Tokyo, Japan.The single-pass linear birefringence was evaluated at 546.5 nm for the central

Biocompatibility of Intraocular Lenses
Eye & Contact Lens: Science & Clinical Practice, 2003The choice of intraocular lens (IOL) implanted by cataract surgeons has significant implications for the effectiveness of the operation and the subsequent need for capsulotomy.Comparison of pertinent peer-reviewed literature published from 1996 through 2001 obtained from a MEDLINE literature search on biocompatibility indicators and IOLs.

Keratoplasty and Intraocular Lenses
Cornea, 1985This paper describes the surgical results in 163 patients in whom intraocular lenses (IOL) had been implanted, exchanged, or removed during penetrating keratoplasty (PKP). They were divided into the following groups: PKP, cataract extraction, and IOL implant; PKP in aphakia and IOL implant; PKP and IOL exchange; PKP and IOL removal. In all groups clear

The following points should be considered regarding removal of an IOL: 1. Be sure that it is an offending agent and not an innocent bystander before deciding to remove it. 2. An offending IOL may usually be replaced with an anterior chamber lens, with excellent results. 3.

ABSTRACT We found that an intraocular lens with a bonded coating of sodium hyaluronate caused less cell damage than an uncoated lens. We also found that an intraocular lens bonded with sodium hyaluronate will provide not only better adherence to viscoelastic materials and endothelial protection, but also may allow for better manipulation of ...

Journal of Cataract and Refractive Surgery, 1990
Current multifocal intraocular lens designs incorporate refractive or diffractive optical principles to achieve increased depth of focus. Information about four basic design concepts is presented. Early clinical results with two of these, the IOLAB Nuvue two-zone refractive multifocal and the 3M diffractive multifocal, are summarized.

An in-depth review of the current status of soft intraocular lenses (IOLs) is presented. We have outlined the historical aspects of IOL development from polymethylmethacrylate material to newer soft polymers such as silicones and hydrogels. Chemical, physical, and biomaterial properties as well as the advantages and disadvantages of these materials and
