A 70-year-old white woman presented to her ophthalmologist with bacterial conjunctivitis resistant to treatment. The relationship between the patient's globe and superior orbital rim prompted high clinical suspicion of an occult foreign body as the cause. The following article describes the office visits preceding the discovery of two adhered soft contact lenses lodged in the superior fornix of the right eye that had been hidden for 15 years. We discuss the role her unique orbital anatomy played in successfully concealing these foreign bodies for over a decade. In addition, we present an algorithm to practice when an occult foreign body is suspected, which includes effective clinical techniques.

Background: Orthokeratology (OK) contact lenses are increasingly prescribed for myopia control but their impact on corneal epithelial immune cells (CEIC) is unclear. This study compares CEIC in OK wearers to soft contact lens (SCL) wearers and non-wearers.
Methods: In vivo confocal microscope images at the corneal central and mid-peripheral subbasal level were evaluated in 18 OK wearers, 18 SCL wearers and 18 non-wearers (mean age 27.

This review is about drops of a liquid with high dielectric permittivity that slide over a solid surface with high electrical resistivity. A typical situation is a water drop sliding down a tilted hydrophobic plate. It has been realized recently that such drops spontaneously acquire a charge.

Introduction: Accurate prediction of knee biomechanics during total knee replacement (TKR) surgery is crucial for optimal outcomes. This study investigates the application of machine learning (ML) techniques for real-time prediction of knee joint mechanics.
Methods: A validated finite element (FE) model of the lower limb was used to generate a dataset of knee joint kinematics, kinetics, and contact mechanics.

The ability to convert moisture signals into electrical signals through contactless control underpins a wide range of applications, including health monitoring, disaster warning, and energy harvesting. Despite its potential, the effective utilization of low-grade energy remains challenging, as it often requires complex device architectures that limit scalability and integration, particularly in wearable technologies. Here, we present a soft, flexible moisture-electric converter made from cellulose nanocrystals and polyvinyl alcohol composite films, designed for a novel touchless interactive platform.

Droplet evaporation on solid substrates is a ubiquitous phenomenon and is relevant in many natural and industrial processes. Whereas it has been reported that the evaporation process is sped up on soft substrates compared with that on hard substrates, no attempt has been made in exploring how substrate stretching affects droplet evaporation and evaporative deposition patterns. Here, we systematically investigate the contact line dynamics of droplets evaporating on substrates with different stiffnesses and stretching ratios and the structures of the evaporative deposition patterns of nanoparticles.
