Abstract: Molded ophthalmic lenses with improved optical qualities can be manufactured at high volumes at low costs to provide single-use lenses. These ophthalmic lenses are contact lenses for examination or treatment of the interior of an eye, are formed of a moldable material, and have a ring portion integral with an optical and eye contacting portions. The ring portion extends from the main body and the ratio of the height of the ring portion to thickness of the lens is about 0.1 to 0.2. These features reduce production costs and improve the optical quality of the lens including allowing any debris, bubbles and the like that tend to adhere to the surface of the mold during the molding process to collect away from the optical centerline of the lens so as to improve the optical quality of the molded ophthalmic lens and minimizing shrinkage during the molding process.

Abstract: Molded ophthalmic lenses with improved optical qualities can be manufactured at high volumes at low costs to provide single-use lenses. These ophthalmic lenses are lenses for examination or treatment of the interior of an eye, are formed of an optical grade plastic, and have a ring portion integral with an optical portion. The ring portion extends from and circumferentially around the optical portion and the height of the ring portion is less than the thickness of said optical portion. These features reduce production costs and improve the optical quality of the lens including allowing any debris, bubbles and the like that tend to adhere to the surface of the mold during the molding process to collect away from the optical centerline of the lens so as to improve the optical quality of the molded ophthalmic lens and minimizing shrinkage during the molding process.

Abstract: An apparatus, method and kit includes one or more use protocol indicators having a color changeable dye, the dye being translucent or having a first color upon immediate exposure to an environment and for a defined time thereafter and the dye changing color after exposure to the environment for the defined time. A dual environment indicator includes a first indicator color changeable dye being translucent or having a first color upon immediate exposure to a first environment and changing color after exposure to a second environment and a second indicator color changeable dye being translucent or having a first color upon immediate exposure to the second environment and for a defined time thereafter and changing color after exposure to the second environment for the defined time. A time exposure indicator comprises at least one color changeable dye disposed to change color in a sequential manner.

Abstract: A method and system directs therapeutic light of a first wavelength to a patient's eye to excite a photosensitizing agent for PDT during a series of discrete periods of time that are separated by non-therapeutic intervals. Diagnostic light of a second wavelength can be directed to the eye during at least a portion of one or more of the non-therapeutic intervals to allow a physician to see the affect of the therapy.

Abstract: An apparatus for directing light to an eye for exciting a photosensitizer includes an addressable LED array so that the size and shape of the LED light used for aiming or therapy is selectable so as to match the size and shape of targeted tissue. The LED array has a configuration that provides increased LED density, increased current spreading with minimal light blocking and a simplified addressing connection sheme.
