PURPOSE We aimed to evaluate the product performance of a novel one-step hydrogen peroxide cleaning and disinfecting solution, PeroxiClear ("Test" solution), when used by habitual Clear Care users to bilaterally clean and disinfect their soft contact lenses, for approximately 2 weeks. METHODS This was a 2-week, open-label, bilateral eye study designed to include subjects ranging in age from 1...

PURPOSE To assess the use of multipurpose lens care products via an online survey conducted among soft contact lens (SCL) wearers in Japan. METHODS The subjects were 1000 men and women aged 15-44 years who reported that they cleaned their SCL by using multipurpose solution at least twice a week. Via the internet, they were asked questions about SCL care, the use of a rubbing step when cleanin...

BACKGROUND/AIM Contact lens cases contaminated with Acanthamoeba are a major risk factor for an infection of the eye. In this study the anti-Acanthamoeba activity of three different contact lens storage solutions was tested. METHODS A new multipurpose contact lens storage solution (Meni Care Plus) and a two step (Titmus H(2)O(2)) and one step (Oxysept Comfort) hydrogen peroxide system were te...

PURPOSE Tear exchange under a soft contact lens is directly related to the amount of lateral and transverse lens motion. Hydrodynamic modeling suggests that channels placed on the back surface of a soft lens will reduce fluid resistance and increase transverse lens movement. This study measured the effect of posterior lens surface scalloped channels on tear exchange. METHODS Tear exchange in ...

Contact lenses are increasingly used in laboratories for in vivo animal retinal imaging and pre-clinical studies. The lens shapes often need modification to optimally fit corneas of individual test subjects. However, the choices from commercially available contact lenses are rather limited. Here, we report a flexible method to fabricate customized hydrogel contact lenses. We showed that the fab...

Contact lens-related eye infections, which can lead to serious outcomes, including blindness, are associated with several risk factors, including sleeping in lenses, exposing lenses to water, not adhering to replacement schedules, and reusing disinfecting solution (1). In some studies, adolescent and young adult contact lens wearers have been reported to be more likely than older adult contact ...

The use of hydrophilic contact lenses has recently been recommended in a variety of pathological conditions. The results have so far been encouraging, but large series with reports of complications as well as of success rates have not yet appeared. The following case represents an instance of corneal abscess caused by a usually nonpathogenic organism in association with the use of a soft contac...

Customized contact lenses are limited in their correction performance, especially on irregular corneas, owing to decentration and rotation of the lenses. To overcome this limitation, we proposed to customize the back surface of soft contact lenses to match the anterior irregular corneal surface. These lenses were designed to correct anterior corneal aberrations and to improve lens stability. Al...
