Effectiveness of multifocal and monofocal intraocular lenses for cataract surgery and lens replacement: a systematic review and meta-analysis.

Purpose: Multifocal intraocular lenses (IOLs) offer the possibility of spectacle-free vision following cataract surgery compared to standard IOLs. Existing systematic reviews have generally concluded that multifocal IOLs result in better uncorrected near vision and greater spectacle independence, but more unwanted visual phenomena such as glare and halos, compared to monofocal IOLs. However, the certainty of evidence has been low for most outcomes, and pooled analyses have grouped together technologically obsolete lenses with newer lenses, potentially obscuring differences in performance across different lens types.

Development of a nomogram for femtosecond laser astigmatic keratotomy for astigmatism after keratoplasty.

Purpose: To develop a nomogram for femtosecond laser astigmatic keratotomy (AK) to treat post-keratoplasty astigmatism.

Setting: Three academic medical centers.

Design: Retrospective interventional case series.

Cystoid macular edema without macular thickening: a retrospective optical coherence tomographic study.

Background: This is a retrospective observational case series of 37 eyes of 32 patients meeting the inclusion criteria intended to describe the appearance, prevalence, and associated risk factors for cystoid macular edema in eyes with normal foveal thickness and contour as determined by optical coherence tomography (OCT).

Methods: A retrospective review of all patients with macular disease who underwent OCT evaluation at the New England Eye Center from January to March 2007 and met the study inclusion criteria was performed. Optical coherence tomography scans were evaluated for the presence of intraretinal cystic fluid or cystoid macular edema but with normal retinal thickness and foveal contour.

Vernal conjunctivitis.

Vernal conjunctivitis is a bilateral, seasonal, external ocular inflammatory disease of unknown cause. Afflicted patients experience intense itching, tearing, photophobia, and mucous discharge, and usually demonstrate large cobblestone papillae on their superior tarsal conjunctiva and limbal conjunctiva. It primarily affects children, may be related to atopy, and has environmental and racial predilections.

Recipients of blood from a donor with multiple HLA antibodies: a lookback study of transfusion-related acute lung injury.

Background: The effects of transfusion of HLA antibodies to patients with corresponding antigens are not well known.

Study Design And Methods: Records of patients who received blood from previous donations of a donor implicated in a case of transfusion-related acute lung injury (TRALI) were examined. The donor had multiple HLA antibodies reactive with 96 percent of HLA Class I antigens and 88 percent of HLA Class II antigens.
