Wear Experiences with Two Soft Contact Lenses for Astigmatism of Different Modalities.

Introduction: Patients expect to have excellent vision and comfort when wearing soft contact lenses. The purpose of this study was to compare the wear experiences of participants with astigmatism when wearing a daily disposable soft toric lens to an established, commonly used reusable toric lens.

Methods: In this crossover study, habitual soft toric lens wearers were fit with a daily replacement soft toric lens (delefilcon A) and a reusable, 1-month replacement soft toric lens (comfilcon A) in a randomized order.

Evaluation of Wear Experience with Soft Daily Disposable Lenses for Astigmatism over 16 Hours of Wear.

Objective: The purpose of this study was to assess the wear experience of participants while wearing a toric daily disposable contact lens with water surface technology over long days of lens wear.

Methods: Existing soft toric contact lens wearers were fit with the daily disposable study lenses. Participants assessed their initial comfort, vision, and satisfaction with the lenses by visual analog scale (VAS) survey.

Long Day Wear Experience with Water Surface Daily Disposable Contact Lenses.

Objective: The purpose of this study was to assess the wear experience of silicone hydrogel daily disposable contact lenses with water surface technology over a long day of lens wear.

Methods: Thirty-five soft contact lens wearers were refit with the daily disposable study lenses and participants scored their initial impressions of comfort, vision and satisfaction using a visual analog scale (VAS). Participants used their smart phones to complete surveys of comfort and vision on a scale of 1-10 at 10, 12, 14, and 16 hours of lens wear on 5 weeknights.

A randomized clinical trial of burst vs. spaced physical therapy for Parkinsons disease.

Introduction: The optimal timing for physical therapy (PT) delivery in Parkinson's disease (PD) is unknown. Our objective was to determine whether spacing physical therapy visits over a longer period of time is beneficial for maintenance of physical function in PD.

Methods: A single center, single-blinded, randomized controlled trial of PD participants.

Radiation Dose Audit Failures: Truth and Consequences.

The validation of a radiation sterilization dose involves an initial sterilization dose determination as well as maintenance of that sterilization dose. The procedures for maintenance of the sterilization dose typically include the periodic use of two types of tests: bioburden and dose audits. The details for the procedures are outlined in the ISO radiation sterilization standards.

Efficacy of gait training with real-time biofeedback in correcting knee hyperextension patterns in young women.

Study Design: Single cohort study.

Objectives: To investigate the efficacy of real-time biofeedback provided during treadmill gait training to correct knee hyperextension in asymptomatic females while walking.

Background: Knee hyperextension is associated with increased stress to the posterior capsule of the knee joint, anterior cruciate ligament, and the anterior compartment of the tibiofemoral joint.
