“…Sleeping in contact lenses is one of the most frequently reported contact lens risk behaviors and one with a high relative risk for corneal infection. 3,4 Sleeping in lenses has been shown to be a risk factor regardless of lens material and frequency, with even occasional overnight use conferring risk. 5,6 Although some contact lenses are approved by the FDA for overnight wear, the increased risk for infection is acknowledged by their classification as a class 3 medical device, which includes medical devices with the greatest risk for harm, such as intraocular lenses and implantable pacemakers.…”

“…2 Among the many behaviors that increase the risk for a contact lens-related corneal infection, sleeping in lenses is one of the riskiest and one of the most commonly reported behaviors among adolescent and adult contact lens wearers. 3 Approximately one third of contact lens wearers report sleeping or napping in their lenses. Sleeping in lenses, whether inadvertently, occasionally, or as part of a prescribed wearing schedule (ie, extended-wear lenses), increases the risk for contact lens-related eye infections 6-to 8-fold.…”

Editor's note: This article is part of a regular series on emerging infection from the Centers for Disease Control and Prevention (CDC) and the EMERGEncy ID NET, an emergency department-based and CDC-collaborative surveillance network. Important infectious disease public health information with relevance to emergency physicians is reported. The goal of this series is to advance knowledge about communicable diseases in emergency medicine and foster cooperation between the front line of clinical medicine and public health agencies.

“…It has been estimated that there are 175 million full or part-time contact lens wearers worldwide [15]. In 2016, the number of contact lens wearers in the United Kingdom and the United States were reported to be 4.2 million and 45 million respectively [16,17]. While the global market value for soft contact lenses has been reported to be growing by at least 4-6% over the past years, and to be in excess of $8.5 billion in 2018 [18], it is not clear whether the actual number of contact lens wearers is increasing at the same rate.…”

Daily disposable (DD) contact lenses first came to the market approximately 25 years ago and eye care professionals (ECPs) started prescribing silicone hydrogel (SiH) contact lenses, primarily for extended or continuous wear, approximately 20 years ago. It has now been over ten years since SiH DD contact lenses have been available, and while SiH materials are routinely prescribed by ECPs for reusable daily wear, hydrogel materials are still frequently selected for the DD modality of contact lens wear. This article reviews the evidence to support the benefits of both a DD modality and SiH materials and how patients' needs may be met with SiH DD contact lenses, with respect to clinical performance, health outcomes, satisfaction, compliance and convenience. Factors which may enable or constrain ECPs from prescribing SiH DD contact lenses, as opposed to hydrogel DD and reusable contact lenses, for more of their patients are discussed with the objective of providing ECPs with a greater understanding of the advantages that can be afforded by prescribing SiH DD contact lenses to both their new and existing contact lens wearers.

“…For example, bacterial biofilm formation on medical implants increases a patient's risk of serious infection [9]. Among these devices are hip and knee implants [10], dental implants [11][12][13], artificial pacemakers [14], and fluid shunts [15], as well as non-permanent devices such as intravenous catheters [16], ventilators [17], and contact lenses and cases [18,19]. By preventing the initial adhesion of biofilms to medical devices, the chance of associated bacterial infections will decrease dramatically [9].…”

Biofilm rupture by laser-induced stress waves increases with loading amplitude, independent of location

Integral to the production of safe and biocompatible medical devices is to determine the interfacial properties that affect or control strong biofilm adhesion. The laser spallation technique has recently emerged as an advantageous method to quantify biofilm adhesion across candidate biomedical surfaces. However, there is a possibility that membrane tension is a factor that contributes to the stress required to separate biofilm and substrate. In that case, the stress amplitude, controlled by laser fluence, that initiates biofilm rupture would vary systematically with location on the biofilm. Film rupture, also known as spallation, occurs when film material is ejected during stress wave loading. In order to determine effects of membrane tension, we present a protocol that measures spall size with increasing laser fluence (variable fluence) and with respect to distance from the biofilm centroid (iso-fluence). Streptococcus mutans biofilms on titanium substrates serves as our model system. A total of 185 biofilm loading locations are analyzed in this study.We demonstrate that biofilm spall size increases monotonically with laser fluence and apply our procedure to failure of non-biological films. In iso-fluence experiments, no correlation is found between biofilm spall size and loading location, thus providing evidence that membrane tension does not play a dominant role in biofilm adhesion measurements. We recommend our procedure as a straightforward method to determine membrane effects in the measurement of adhesion of biological films on substrate surfaces via the laser spallation technique.
