Clinical Comparison of a Small-Aperture Intraocular Lens Versus a Monofocal Control.

Purpose: To evaluate range of visual acuity, visual quality, and safety of the IC-8 small-aperture (SA) intraocular lens (IOL) (Apthera; Bausch & Lomb, Inc) in patients with cataract.

Methods: This was a prospective, multicenter, open-label, parallel-group, non-randomized, examiner-masked, 12-month clinical study conducted at 21 sites in the United States. Included patients (N = 453) received either the SA IOL (targeted to -0.

[Methods of Measuring Limb Malrotation Following Femoral Osteosynthesis].

Significant malrotation of the femur after osteosynthesis is a serious complication of treatment and has a number of consequences for the patients and causes deterioration of their quality of life. Therefore, it is necessary to be familiar with intraoperative techniques to control the correct rotation, mostly clinical and radiological, which give us the possibility to minimize rotational errors. In the postoperative period, with even a slight suspicion of malrotation, it is necessary to proceed to its exact verification and, in indicated cases, to perform necessary correction.

Metastatic Adenoid Cystic Carcinoma at the Base of the Tongue and Duplicate Breast Cancer Diagnosed During Restaging.

Background/aim: Adenoid cystic carcinoma (AdCC) is a rare malignant tumor that primarily affects the salivary glands but can also occur in other organs. Low incidence and unpredictable clinical behavior make AdCC one of the most difficult head and neck tumors to treat.

Case Report: We present the case of a 54-year-old woman with AdCC localized at the base of the tongue, following radical surgical and oncological therapy.

Evaluating the small aperture intraocular lens: depth of focus and the role of refraction and preoperative corneal astigmatism in visual performance.

Purpose: To evaluate depth of focus (DOF) and visual acuities (VAs) by manifest refractive spherical equivalent (MRSE) and degree of preoperative corneal astigmatism with the IC-8 small aperture intraocular lens (SA IOL) (Apthera).

Setting: 21 investigational sites in the United States.

Design: Prospective, multicenter, open-label, parallel-group, nonrandomized, examiner-masked, 1-year clinical study.

Cyclic Testing of Polymer Composites and Textile Cords for Tires.

This paper is oriented toward the specific testing of polymer composites and textile PA66 cords used as reinforcement for composites. The aim of the research is to validate the proposed new testing methods for low-cyclic testing of polymer composites and PA66 cords for the characterization of material parameters useful as input data for computational tire simulations. Part of the research is the design of experimental methods for polymer composites and test parameters such as load rate, preload, and other parameters such as strain for the start and stop of cycle steps.
