Late postoperative opacification of MemoryLens hydrophilic acrylic intraocular lenses: case series and review.

Purpose: To report clinical and spectrographic analyses of 2 explanted hydrophilic acrylic intraocular lenses (IOLs).

Setting: John A. Moran Eye Center, Salt Lake City, Utah, USA, and Johannes Gutenberg-University, Department of Ophthalmology, Mainz, Germany.

Reducing dust, lead, dust mites, bacteria, and fungi in carpets by vacuuming.

Old carpets may be reservoirs of dust, lead (Pb), and dust mite allergen. The purpose of this study was to determine if the dust, Pb, dust mite allergen, bacteria, and fungi on the surface of carpets could be reduced by 90% in 1 week with the use of a Hoover Self Propelled Vacuum with Embedded Dirt Finder (HSPF). A high-volume surface sampler (HVS3) was used to measure surface dust and pollutants before and after the use of the HSPF to remove deep dust in carpets 12 to 20 years old in nine middle-class homes and two small offices.

Topical anesthetic abuse ring keratitis: report of four cases.

Purpose: We present the clinicopathologic correlations of two case and two other clinical cases of topical anesthetic abuse keratopathy that were originally diagnosed as Acanthamoeba keratitis because of ring keratitis presentation and characteristic history.

Methods: Four patients who were referred to us with suspected Acanthamoeba keratitis are included. Each was initially treated for amoebic keratitis, by using established protocols, and only later was the true origin (topical anesthetic abuse) uncovered.

Pseudophakic keratoplasty: posterior chamber lens implantation in the presence of ruptured capsule.

A technique is described for implantation of a posterior chamber intraocular lens during keratoplasty for bullous keratopathy when a large capsulotomy and vitreous prolapse are present. Seven cases of pseudophakic or aphakic bullous keratopathy with anterior chamber, iris-fixated, or no intraocular lens in place are reported. A completely intact posterior capsule is not necessary to support safely a sulcus-fixated posterior chamber lens.
