295 results about "Liquid Change" patented technology

A liquid begins to change to a gas when a molecule has enough kinetic energy to break the intermolecular bonds holding it together. Let's use an analogy to illustrate this point. Imagine a crowd of 20 people holding each other tightly together, arms locked, legs tied together.

Accommodating intraocular lens

InactiveUS20100094412A1Correct visual impairmentImproved ocular implantEye surgeryIntraocular lensLiquid ChangeHigh surface
An improved multifocal design for an ocular implant is provided. This ocular implant can include an accommodating intraocular lens (IOL) and a number of haptics. The accommodating IOL includes a liquid suspended between two optically transparent plates or membranes to form a pressure lens that passes optical energy. The haptics mechanically couple to the IOL in order to position and secure the IOL within the eye. The IOL achieves accommodation by using the eye's ciliary muscles to vary the surface curvature of the liquid. The liquid may have a high surface tension and be surrounded by phobic liquid. Pressure from the ciliary muscles causes fluid to be added from or withdrawn to a reservoir. Increasing / decreasing the internal pressure of the liquid changes the angle (curvature) of the surface thus changing the optical properties of the lens. When the pressure is released the liquid returns to the reservoir. The whole system may be sealed off from the interior of the eye by a membrane / transparent lens.
