Unlabelled: This literature review looks at the current status of multifocal intraocular lenses (IOLs) in cataract surgery. The results of implantation of multifocal IOLs of diffractive, refractive, and hybrid diffractive-refractive design are described with regard to uncorrected near and distance visual acuity and spectacle independence. The occurrence of photic phenomena and contrast sensitivity loss with multifocal IOLs are also addressed.

A 48-year-old myopic patient with bilateral anterior chamber depth of 3.1 mm and endothelial cell density (ECD) of 2525 cells/mm(2) and 2638 cells/mm(2) preoperatively had bilateral implantation of an Artisan iris-fixated phakic intraocular lens (pIOL). Five years postoperatively, unilateral corneal stromal edema was seen in a circumscribed area overlying the temporal ridge of the pIOL in the right eye; the ECD was 1631 cells/mm(2) and the pachymetry, 586 microm.

Purpose: To report the results of cataract surgery after previous implantation of an Artisan iris-fixated phakic intraocular lens (pIOL) for the correction of myopia.

Setting: University center and private practice.

Methods: This study comprised eyes with previous implantation of an iris-fixated pIOL to correct myopia and subsequent pIOL explantation combined with cataract surgery and in-the-bag implantation of a posterior chamber IOL.

A 66-year-old woman was referred to us due to visual complaints after cataract surgery. The patient's complaints were decreased visual acuity and a localized blur in her visual field. At slit lamp biomicroscopy, an unusually long and centrally located clear corneal incision was noted.

Purpose: To present clinical data from a single-center prospective clinical trial of the AcrySof toric intraocular lens (IOL).

Setting: Academic Hospital Maastricht, Maastricht, The Netherlands.

Purpose: To report the long-term performance of the AcrySof ReSTOR SA60D3 intraocular lens (IOL) after cataract surgery.

Setting: University Hospital Maastricht, Maastricht, The Netherlands.

Methods: This prospective clinical trial comprised 44 eyes (22 consecutive patients) having cataract surgery with implantation of the ReSTOR IOL.

Purpose: To measure intraocular straylight (as a measure of glare) after cataract surgery and implantation of an AcrySof ReSTOR SA60D3 multifocal or AcrySof SA60AT monofocal intraocular lens (IOL) (both Alcon Laboratories).

Setting: University Hospital Maastricht, Maastricht; Isala Clinics, Zwolle; Netherlands Institute for Neurosciences, Amsterdam, The Netherlands.

Methods: In a prospective open observational case series, a newly developed straylight meter was used to objectively measure straylight 6 months postoperatively in 66 eyes with a diffractive AcrySof ReSTOR SA60D3 IOL (multifocal group) and 40 eyes with a monofocal AcrySof SA60AT IOL (monofocal group).

Purpose: To describe a patient who underwent implantation of a Verisyse/Artisan iris-fixated phakic intraocular lens (IOL) for correction of high myopia in pellucid marginal degeneration (PMD).

Methods: A patient with PMD was observed during a period of 7 years after the implantation of a Verisyse/Artisan phakic IOL. At each visit, slit-lamp evaluation was performed, and corneal topography, endothelial cell count, manifest refraction, and uncorrected and best-corrected visual acuity were determined.
