A Review of Contact Lens-Related Risk Factors and Complications

Abstract

The purpose of this article is to develop a modern strategy for handling difficulties related to contact lenses and their care. A growing number of people throughout the world are currently concerned by eye-related undesirable activities in allergy sufferers and those wearing contact lenses. While many wearers who experience ocular discomfort exhibit dryness as a symptom, many other contact lens-related pain symptoms also include irritation and fatigue, and managing coexisting diseases must be done in accordance with aspects of wearing contact lenses, all of which undoubtedly increase discomfort.It is typical for contact lens storage containers to have persistent microbial contamination, which has been linked to microbial keratitis (MK) and clear corneal invasion. Contact lens-associated MK is an interesting, potentially sight-threatening complexity arising from wearing soft contact lenses. Estimates show that for every 10,000 persons who wear contact lenses each year, there are 2 to 5 occurrences of MK. Investigating separate determinants for contact lens-associated MK and evaluating their impact on infection load is one of the challenges in their administration. It is hoped that this will offer a useful outline of the complicated issues of contact lens wear that are both infectious and non-infectious. Recent epidemiological studies detailing the risk factors associated with contact lens use, and the effect of pathogen and individual immune profiles on the severity of diseases have enlightened how we might interpret the prophylaxis and prevention of contact lens-related corneal infection. The most dreaded side effect of contact lens use, infectious keratitis linked with contact lenses, will be reviewed, along with the most recent advancements in its diagnosis and treatment.

Post-Keratoplasty Microbial Keratitis in the Era of Lamellar Transplants—A Comprehensive Review

“…Another explanation for this etiological shift towards Gram-negatives might be related to the increased contact lens (CL) wear. Pseudomonas aeruginosa dominates in the prevalence of CL-related keratitis [1].…”

“…The growing number of contact-lens-wearers contributes to a higher incidence of microbial keratitis [1]. Infectious keratitis (IK) poses a significant threat for corneal transparency.…”

Effectiveness of toric soft contact lenses for vision correction in patients with different degrees of astigmatism: a real-world study

“…Soft contact lenses, in a "safe, convenient and aesthetic" way, overcome the reduction of the image of objects and the trigeminal effect, which is caused by glasses. It has become an important means of refractive error correction [3][4] . However, astigmatism correction is a huge challenge for soft contact lenses.…”

Association BetweenSerratia marcescensContamination and Hygiene Compliance in Orthokeratology

“…The contamination of contact lens and their storage containers have been linked to cases of microbial keratitis (5,6). The cause of contact lens-associated eye disease includes the introduction of pathogens into the eye and corneal hypoxia resulted from long-term wearing of contact lens, especially those made using low oxygen transmissibility material (low DK/t), and it probably leads to an unhealthy epithelium and is an entry point for microorganisms (7,8). In contact lens case surveys conducted in various countries, the microbial detection rate in storage cases has been found to exceed 50% (9).…”
