A grafted glycosaminoglycan polymer is disclosed. The grafted glycosaminoglycan polymer comprises a glycosaminoglycan having a polymer backbone and one or more side chains comprising a polyalkylene glycol-containing residue grafted onto the polymer backbone.

A contact lens cleaner device which can be used to clean contact lenses from debris and bacteria. The contact lens cleaner device pumps contact lens solution into reservoirs where contact lenses can be placed. The contact lenses rotate within the reservoirs and debris falls into a filter, as the contact lens solution continues to be pumped through the device. UV-lighting kills bacteria and cleanses the contact lenses in the reservoirs.

A method of enhancing the growth of an animal, as well as treating or preventing antimicrobial infections is provided. The method includes causing the animal to ingest or absorb an effective amount of one or more Fe III complex compounds, including but not limited to Fe III complexes comprising ligands bound to the iron center such as amino acids or -hydroxy acids. The compounds are also useful for inhibiting, reducing, or preventing biofilm formation or buildup on a surface; the treatment of, inhibition of growth of, and inhibition of colonization by, bacteria, both in biological and non-biological environments; disinfecting surfaces, potentiating the effects of antibiotics and other anti-microbial agents, and increasing the sensitivity of bacteria and other microorganisms, to anti-microbial agents are also provided.

A contact lens solution for enhancing moist sensation and a contact lens product are provided. The contact lens solution includes a comfort enhancing ingredient. The content of the comfort enhancing ingredient is between 0.01 wt % and 3 wt % based on 100 wt % of the contact lens solution. The comfort enhancing ingredient has one or more glutamic acid monomers, and has a number average molecular weight between 3,000 Daltons and 1,500,000 Daltons to allow the contact lens solution to have a viscosity between 1 cPs and 3 cPs.

An eye-mountable device includes a hydrogel material. By drying the hydrogel material of the eye-mountable device, ethylene oxide may be used to sterilize the eye-mountable device. Such a sterilization method can be employed to sterilize the eye-mountable device when the eye-mountable device includes electronics, sensors, actuated lenses, or other components that may be damaged by heat, pressure, radiation, or other conditions used for sterilization. The eye-mountable device may be stored, dry, within a sealed sterile volume of a packaging material. The packaging material may be permeable to ethylene oxide such that the dried eye-mountable device may be sterilized by ethylene oxide after being sealed within the packaging material. The eye-mountable device could take the form of a contact lens, the form of a device configured to be placed against a sclera of an eye beneath an eyelid of the eye, or could take some other form.

A method of operating a sterilization system having a vacuum chamber for sterilizing instruments, the chamber connected to a reservoir of sterilant by a valve in a closed state, is disclosed. The method may include taking a baseline humidity measurement while the pressure within the chamber is a first pressure, lowering the pressure within the chamber to a conditioning pressure, maintaining the conditioning pressure for a dwell time, increasing the pressure within the chamber, acquiring a second humidity measurement from within the chamber, and comparing the baseline humidity measurement to the second humidity measurement.
