Abstract: This invention relates to novel whitening agents for cellulosic substrates. The whitening agents are comprised of at least two components: at least one chromophore component and at least one polymeric component. Suitable chromophore components generally fluoresce blue, red, violet, or purple color when exposed to ultraviolet light, or they may absorb light to reflect these same shades. The whitening agents are further characterized by having a dispersion component value of the Hansen Solubility Parameter of less than or equal to about 17 MPa0.5. This invention also relates to laundry care compositions including but not limited to liquid and/or powder laundry detergent formulations and rinse added fabric softening (RAFS) compositions that comprise such whitening agents.

Abstract: An ophthalmic surgical apparatus for use with an eye including a tube adapted to be in fluid communication with the eye, a pressure sensor adapted to measure an intraocular pressure value of the eye, a fluid reservoir comprising a moveable wall, the fluid reservoir adapted to be in fluid communication with the eye through the tube, and at least one processor coupled to the pressure sensor to receive the measured intraocular pressure value, the at least one processor operable to position the moveable wall in response to a difference between the measured intraocular pressure value and a target intraocular pressure value.

Abstract: An ophthalmic injection system having coaxial cannulae includes a plurality of syringe bodies and a plurality of cannulae, wherein a first non-flexible cannula is configured to accommodate and guide a second cannula that moves inside the first cannula and penetrates into the internal cavity of an eye globe. The first cannula is long enough to penetrate one or more outer layers of the eye globe. A syringe body is connected to the second cannula for accommodation and infusion of a pharmaceutical composition. A plunger is inserted into an annular space of the second syringe body at its distal end for injecting the pharmaceutical composition to the surgical site.

Abstract: A liquid supply system supplies liquid to a hopper upon liquid within the hopper reaching a low liquid level. The liquid may be heated within a liquid reservoir and within a liquid conduit between the reservoir and the hopper.
