COVID-19 reinfection after pregnancy.

Background: There have been reports of COVID-19 reinfections, but the immunological characterization of these cases is partial. We report a case of reinfection with SARS-CoV-2, where the first infection occurred in the course of late pregnancy.

Case Presentation: On May 27, 2020, a 37-year-old woman gave birth at full term, 3 hours after full dilatation.

Optical evaluation of new-design multifocal IOLs with extended depth of focus.

In this study, we investigate in vitro the optical performance of new-design extended depth of focus (EDOF) complementary intraocular lenses (IOLs) (ACTIVE, Cristalens Industrie, France), compared with traditional bifocal ones. Evaluation of their optical quality was achieved by measuring the point spread function at multiple distances (through focus) using an optical bench. In addition, the modulation transfer function through focus was calculated, correlating our results with actual visual outcomes.

Evaluation of UVA Cytotoxicity for Human Endothelium in an Ex Vivo Corneal Cross-linking Experimental Setting.

Purpose: To evaluate endothelial cytotoxicity after exposure of human corneas to ultraviolet-A (UVA) (λ = 365 nm; 5.4 J/cm(2)) in an experimental ex vivo corneal cross-linking setting.

Methods: Sixteen pairs of human donor corneas were cut into two pieces.

Double-C loop platform in combination with hydrophobic and hydrophilic acrylic intraocular lens materials.

Purpose: To analyze the behavior of a new double-C-loop quadripod symmetrical intraocular lens (IOL) platform combined with a hydrophilic lens material and a new hydrophobic glistening-free acrylic lens material, Ankoris and Podeye, respectively, in silico (computer simulation), in vitro (laboratory investigation), and in vivo (rabbit model).

Setting: John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA, and Physiol S.
