In order to identify possible risk factors for microbial keratitis the storage cases for contact lenses of 102 asymptomatic lens wearers were tested for contamination by bacteria and free-living amoebae. Of this group 43 had significant counts of viable bacteria and only 40 had negligible counts. Seven had contamination by acanthamoebae, of whom six also had significant bacterial counts. These ...
PURPOSE To evaluate the impact of disposable soft contact lenses upon visual performance by comparing the optical aberrations of myopic eyes with and without the use of contact lenses. METHOD The optical aberrations of a set of 18 eyes were measured by a laser ray tracing system, an objective measurement method, enabling comparison of the findings of the naked eye, the eye plus a test lens, a...

THE increasing recognition of the importance of contact lenses in the treatment of keratoconus has led to a quite exceptional concentration of these cases in the Contact Lens Department at the Royal Westminster branch of the Moorfields, Westminster and Central Eye Hospital. It is possible that the opportunity to analyse in detail such a large series of keratoconus cases has not previously occur...
CONTEXT Fungal keratitis is a potentially blinding condition that is rarely seen with contact lens wear. OBJECTIVE To describe a nationwide outbreak of fungal keratitis caused by Fusarium species among contact lens wearers in Singapore. DESIGN, SETTING, AND PATIENTS Nationwide, hospital-based case series. All cases of fungal keratitis among contact lens wearers in all ophthalmology departme...
Intractable diplopia has been described in many situations but poor results are the rule with standard treatment modalities. The authors report a case of a woman with long-standing strabismus and diplopia who failed to improve following surgery, prism, and occlusive spectacles or contact lenses. Then, she was submitted to phacoemulsification and opaque intraocular lens implantation, which succe...
One of the most common pathogens in infection of hydrogel contact lens wearers is Pseudomonas aeruginosa, which can gain access to the eye via contamination of the lens, lens case, and lens care solutions. Only one strain per species is used in current regulatory testing for the marketing of chemical contact lens disinfectants. The aim of this study was to determine whether P. aeruginosa strain...
