PURPOSE There is increasing interest in fitting children with soft contact lenses. This review collates data from a range of studies to estimate the incidence of complications, specifically corneal infiltrative events and microbial keratitis, in patients under the age of 18 years. METHODS Peer-review papers were identified using PubMed and the Web of Science. A broad range of studies are summ...

BACKGROUND & OBJECTIVES With increasing use of soft contact lenses the incidence of contact lens induced infections is also increasing. This study was aimed to assess the knowledge of new and existing contact lens users about the risk of microbial contamination associated with improper use and maintenance of contact lenses, type of microbial flora involved and their potential to cause ophthalmi...

The use of hydrophilic soft contact lenses for dispensation of pilocarpine is described. The release rate of pilocarpine from three materials of different water content was estimated and from this the surface concentrations were calculated. It is estimated that PolyHEMA can after 15 hours provide a 1 per cent surface concentration of pilocarpine, whereas higher water content materials (70 and 8...

Adhesion of pathogenic microbes, particularly bacteria, to contact lenses is implicated in contact lens related microbial adverse events. Various in vitro conditions such as type of bacteria, the size of initial inoculum, contact lens material, nutritional content of media, and incubation period can influence bacterial adhesion to contact lenses and the current study investigated the effect of ...

To investigate the accumulation of tear proteins on disposable extended-wear contact lenses (42% Etafilcon A and 58% hydration), a technique involving sodium dodecyl sulfate-polyacrylamide minigel electrophoresis combined with a sensitive silver-staining method was used. Besides the binding of large amounts of tear lysozyme the authors found an accumulation of an as yet unidentified 30-kilodalt...

Tear film protein deposition on contact lens hydrogels has been well characterized from the perspective of bacterial adhesion and viability. However, the effect of protein deposition on lens interactions with the corneal epithelium remains largely unexplored. The current study employs a live cell rheometer to quantify human corneal epithelial cell adhesion to soft contact lenses fouled with the...

The purpose of this study was to determine the changes in the relative Aim: peripheral refractive error produced by soft single vision contact lenses in myopic schoolchildren. 27 myopic schoolchildren aged between 13 to 15 years were Methods: included in this study. The measurements of central and peripheral refraction were made only on the right eye using a Grand-Seiko WR-5100K open-field auto...
