Methods and Systems for Solvent-Free Cleaning of Surfaces
An exemplary embodiment of the present disclosure provides solvent-free cleaning systems and methods, the systems and methods comprise a polymer substrate having a crosslinked matrix positioned on at least one surface of the polymer substrate, wherein the crosslinked matrix is configured to absorb particulates from a surface of a material when placed in direct contact.
PACKAGING SOLUTIONS
A packaging system for the storage of an ophthalmic device is disclosed. The packaging system includes a sealed container containing one or more unused ophthalmic devices immersed in an aqueous packaging solution that includes ectoine or an ophthalmologically acceptable ectoine derivative. The aqueous packaging solution has an osmolality of at least about 150 mOsm/kg, a pH of about 6 to about 9 and is sterilized.
Copolymer, wetting agent, medical device, and method for producing same
Disclosed are: a polymer for treating the surface of a medical device such as a contact lens to suppress the reduction in lubricity of the device even when the device is scrubbed; a medical device having the polymer on the surface so that the reduction in lubricity over time is suppressed; and a wetting agent containing the polymer. The polymer for treating the surface is a copolymer which is water-soluble and includes as constitutional units the following monomers A and B: monomer A: a monomer containing a (meth)acryloyl group and an ester or amide structure in a molecule, in which the ester or amide structure is not constituted by including a part of the (meth)acryloyl group; monomer B: a monomer containing a (meth)acrylamide group in a molecule and having a structure different from that of the monomer A.

CONTACT LENS AND MANUFACTURING METHOD THEREFOR
A contact lens and a manufacturing method thereof are proposed. The contact lens may include a resin composition containing an acrylic-based monomer and a Boswellia extract. By containing a Boswellia extract, the contact lens can prevent adherence of bacteria when worn on the user's eye and serve as an antibacterial agent to prevent bacterial infection, so it can secure a good contact fit and high antibacterial performance.
OPHTHALMIC DEVICES
A method for preparing an ophthalmic device for slowing, inhibiting or preventing myopia progression involves (a) soaking an ophthalmic device in one or more first solvent solutions to swell the ophthalmic device; (b) soaking the swelled ophthalmic device in one or more second solvents solutions comprising one or more red-light blocking compounds blocking greater than about 5% to about 25% of red-light transmission through the ophthalmic device at a wavelength of from about 550 nanometers (nm) to about 800 nm to de-swell the swelled ophthalmic device and entrap the one or more red-light blocking compounds in the de-swelled ophthalmic device; and (c) sterilizing the de-swelled ophthalmic device.
EYE WASH COMPOSITIONS AND METHODS
This disclosure provides a method of treating an infection or inflammation of an eye of a mammal including contacting an eye with a solution comprising sterilized water and protocatechuic acid. The protocatechuic acid may be between about 0.01 wt % and 1.25 wt % in the solution. The solution may include saline. The solution may include ciprofloxacin and/or norfloxacin. This disclosure further provides a method of disinfecting a contact lens including contacting a contact lens with a solution including protocatechuic acid. The solution may include a surfactant. The surfactant may include polyethylene glycol esters of fatty acids, coconut, polysorbate, polyoxyethylene or polyoxypropylene ethers of high alkanes C12-C18. The surfactant may include poly(oxypropylene)-poly(oxyethylene) adducts of ethylene diamine having a molecular weight about 7,500 to about 27,000 wherein at least about 40 weight percent of the adducts is poly(oxyethylene).
