Poly-Gamma-Glutamic Acid Functions as an Eective Lubricant with Antimicrobial Activity in Multipurpose Contact Lens Care Solutions.

In order to perform the multiple functions of disinfection, cleansing, and storage, preservatives are often added to contact lens care solutions. The disadvantage of adding preservatives is that this often causes various eye conditions. However, lens care solutions would not be able to disinfect in the absence of such preservatives.

The characteristics of a preservative-free contact lens care solution on lysozyme adsorption and interfacial friction behavior.

The population of soft contact lens wearers is increasing, thus the issues of feeling comfortable and contact lens-induced clinical symptoms are concerned. Both lysozyme deposition and mechanical friction among contact lens and the eye can induce discomfort and eye conditions. Therefore, we characterized our developed preservative-free contact lens care solution on lysozyme adsorption and lubrication.
