Complications of foldable intraocular lenses requiring explantation or secondary intervention: 2022 survey with update of long-term trends.

Purpose: To assess the complications that resulted in the explantation or secondary intervention with foldable intraocular lenses (IOLs).

Setting: University setting, Salt Lake City, Utah.

Design: Survey study.

Rotational stability of a new hydrophobic acrylic intraocular lens platform.

Purpose: To evaluate rotational stability for ease of rotation of a new intraocular lens (IOL) platform with 4 haptics in an ex vivo model and compare it with a control single-piece lens with 2 open loops.

Setting: Intermountain Ocular Research Center, John A. Moran Eye Center, University of Utah, Salt Lake City, Utah.

Performance of selected lightweight wheelchairs on ANSI/RESNA tests. American National Standards Institute-Rehabilitation Engineering and Assistive Technology Society of North America.

Objective: This study provides data for clinicians and wheelchair users to compare the durability, stability, and cost effectiveness of three different lightweight wheelchair models: the Everest & Jennings EZ Lite, the Invacare Rolls 2000, and the Quickie Designs Breezy. A second objective was to compare the results from this study to those published for ultralight and institutional depot wheelchairs.

Design: Randomized standards testing of three wheelchair models from each manufacturer (nine wheelchairs total).

The normal thyroidal uptake of iodine.

The range of values for the 24-hour thyroidal accumulation of radioactive iodine in euthyroid persons varies with geographic location. In the San Bernardino Valley region of Southern California the "normal range" is 6 percent to 33 percent in euthyroid subjects. This is lower than in studies from other areas of the United States.
