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.

Intraocular Lenses in Children
International Ophthalmology Clinics, 1977The intraocular lens offers an experimental alternative to be considered for the visual rehabilitation of children with traumatic or unilateral infantile cataracts. The disadvantages of aphakic spectacles or contact lenses and amblyopia have committed many of these eyes to the status of visual cripples.

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 ...

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

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.

Recent advances in the design and material of phakic intraocular lenses have made them very predictable, safe and effective. The use of these lenses in refractive surgery is expected to increase very significantly in the near future. The aim of this review is to update the reader regarding the recent advances reported on this topic during 2007.Several ...

Multifocal intraocular lenses (IOLs) are growing in popularity among patients and surgeons, and opened the way to refractive lens exchange. Still they are not used routinely in cataract surgery, for reasons probably connected to the frequently observed reduction in contrast sensitivity.
