Explanted multifocal intraocular lenses

Journal of Cataract and Refractive Surgery, 2015
We report 2 cases in which single-piece multifocal acrylic intraocular lenses (IOLs) were explanted because of complications related to the presence of glistenings in the bulk of the IOL optic. In both cases, the patients complained about blurry or hazy vision.

Multifocal Intraocular Lenses and Glare

Optometry and Vision Science, 1993
In a previous paper, we reported finding deficits in the contrast sensitivity functions of patients with diffractive multifocal intraocular lenses (IOL's). The results were consistent with optical measurements of the modulation transfer function (MTF) of the IOL.

Multifocal intraocular lenses

Current Opinion In Ophthalmology, 1996
Since the publication of my last article in Current Opinion in Ophthalmology in 1991 (2:33-34), the use of multifocal intraocular lenses (IOLs) has not gained general acceptance among ophthalmologists. Despite this situation, major IOL companies have continued to invest in clinical trials of new designs.

Multifocal intraocular lenses: An overview

Survey of Ophthalmology, 2017
Multifocal intraocular lenses are increasingly used in the management of pseudophakic presbyopia. After multifocal intraocular lens implantation, most patients do not need spectacles or contact lenses and are pleased with the result. Complications, however, may affect the patient's quality of life and level of satisfaction.

Multifocal intraocular lenses

Current Opinion in Ophthalmology, 2005
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.

Contrast sensitivity in multifocal intraocular lenses

Journal of Cataract and Refractive Surgery, 1993
Contrast sensitivity was measured in two groups of 20 patients each implanted with refractive and diffractive multifocal intraocular lenses and in two control groups of 20 patients each--the first group implanted with a monofocal IOL and the second phakic subjects.

Optical performance of multifocal intraocular lenses

Journal of Cataract and Refractive Surgery, 1990
The optical performance of one monofocal and five multifocal lenses was evaluated in the laboratory and photographically. The laboratory testing included determination of the modulation transfer function (MTF), through focus response (TFR), resolution efficiency, and Strehl ratio of each lens.

Optimizing outcomes of multifocal intraocular lenses

Current Opinion in Ophthalmology, 2014
To update the readers on recent research for further optimizing outcomes and improving the patient satisfaction with multifocal intraocular lenses (IOLs).Recent studies provide few novel approaches on surgical interventions to improve the postoperative outcomes.

Intraocular Lens Power Calculations for Multifocal Intraocular Lenses

American Journal of Ophthalmology, 1992
We performed calculations for anterior and posterior chamber intraocular lenses, determining the necessary power for emmetropia and 3 diopters of myopia for various axial lengths and corneal powers. Our results demonstrate that to achieve an effective add of 3.00 diopters at the spectacle plane (reading distance of 33 cm), the fabricated add (labeled ...

Multifocal Intraocular Lenses: Complications

2014
In this chapter, the most common complications after multifocal IOL implantation, as well as the best way to manage them, are described. First of all, we focus on prevention. To achieve a high patient satisfaction, it is very important to use strategies to prevent or to minimize the risk of complications.
