dry eye is the major contributor to computer vision syndrome. the reductions in the blink rate and amplitude have been considered as the possible mechanisms leading to this condition. the purpose of this study is to evaluate the changes in the lower tear meniscus heights and areas in the computer reading task, in dry eye subjects, with and without soft contact lenses. in this quasi-experimental...

A contact lens may be removed from the eye either manually or by using a small rubber sucker. The removal of lenses by the rubber sucker technique is difficult at times, especially when the lens is fenestrated, as the vacuum cannot be maintained. Assistance in the removal of the lens may be obtained by modifying existing rubber suckers. The bulb is cut off with a sharp blade and into the lumen ...

AIMS This study was undertaken to investigate the effects of contact lens disinfecting solutions on strains of Acanthamoeba from the United Kingdom and southern Africa and to compare the results with those of other researchers. No information was previously available for southern African isolates. METHODS 11 contact lens solutions were tested on cysts of 10 strains of Acanthamoeba. RESULTS ...

This short communication reports on the responses of a cohort of more than 2000 contact lens practitioners across five European countries, who were surveyed on the routine use of fluorescein in soft contact lens aftercare. Although corneal staining has received extensive interest amongst the academic community, most practitioners do not routinely use fluorescein at aftercare visits. The argumen...

A five turn coil of magnet wire sandwiched between two soft contact lenses served as a magnetic search coil to measure horizontal and vertical eye movements in humans. The lens was adhered to the eye for 35 min by periodically misting the eye with distilled water; during this time the records of eye position showed that the lens remained firmly attached to the eye. Using this sensor, no topical...

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...
