The invention provides biodegradable implants sized for implantation in an ocular region and methods for treating medical conditions of the eye. The implants are formed from a mixture of hydrophilic end and hydrophobic end PLGA, and deliver active agents into an ocular region without a high burst release.

Ocular implant made by a double extrusion process

Compositions for disinfecting contact lenses include a liquid medium containing a chlorite component, preferably a water soluble chlorite component, in a contact lens disinfecting amount, and a polyanionic component, preferably a water soluble polyanionic component, in an amount effective to do at least one of the following: inhibit formation of protein deposit material on a contact lens immersed in the composition; reduce the toxicity of the composition to the human eye, and reduce the damage to a contact lens caused by immersing the contact lens in the composition. The composition has a viscosity of less than 50 cps at 25.degree. C., an osmolality of at least about 200 mOsmol/kg, and preferably a pH in the range of about 6 to about 9.

Compositions and methods for disinfecting contact lenses and preserving

Compositions and methods useful for disinfecting a contact lens are disclosed. The present methods comprise contacting a contact lens with a liquid medium containing an effective amount of an oxidative disinfectant component at conditions to effectively disinfect the contact lens. The contacting occurs in the presence of a color indicator component which is soluble in the liquid medium and is adapted to provide a color indication of the presence of the oxidative disinfectant component in the liquid medium. The color indicator component comprises an effective amount of a transition metal component which is redox active, has an oxidized state of a first color and a reduced state of a different second color and a polyanionic component in an amount effective to inhibit the staining of the contact lens by the transition metal component.

Compositions and methods for disinfecting a contact lens and detecting

Compositions and methods for disinfecting and cleaning contact lenses include a liquid medium containing hydrogen peroxide and a defined ethylene oxide/propylene oxide block copolymer. An advantageously reduced amount of foaming occurs when the hydrogen peroxide is destroyed, particularly by the action of catalase.

Compositions and methods for disinfecting and cleaning contact lenses

Compositions and methods for disinfecting contact lenses are disclosed. In one embodiment, the present compositions include a liquid medium containing chlorine dioxide precursor in an amount effective to form, when activated, a chlorine dioxide-containing composition including a contact lens disinfecting amount of chlorine dioxide. A polyanionic component, preferably a water soluble polyanionic component, is included in the composition in an amount effective to inhibit the formation of proteinaceous deposit material on a contact lens immersed in the chlorine dioxide-containing composition. Thus, effective contact lens disinfection is achieved while, at the same time, reducing the risk of forming proteinaceous deposit material on the contact lens during the disinfecting processing.

Compositions and methods for disinfecting contact lenses and reducing

The present invention relates to lenses, for example, contact lenses, and to contact lens cases having antimicrobial properties. More particularly, the invention relates to lenses and contact lens cases made from materials which comprise polymeric materials and effective antimicrobial components.
