Surgical correction of human eye refractive errors such as presbyopia, hyperopia, myopia, and stigmatism by using transcutaneously inductively energized artificial muscle implants to either actively change the axial length and the anterior curvatures of the eye globe. This brings the retina / macula region to coincide with the focal point. The implants use transcutaneously inductively energized scleral constrictor bands equipped with composite artificial muscle structures. The implants can induce enough accommodation of a few diopters, to correct presbyopia, hyperopia, and myopia on demand. In the preferred embodiment, the implant comprises an active sphinctering smart band to encircle the sclera, preferably implanted under the conjunctiva and under the extraocular muscles to uniformly constrict the eye globe, similar to a scleral buckle band for surgical correction of retinal detachment, to induce active temporary myopia (hyperopia) by increasing (decreasing) the active length of the globe. In another embodiment, multiple and specially designed constrictor bands can be used to enable surgeons to correct stigmatism. The composite artificial muscles are either resilient composite shaped memory alloy-silicone rubber implants in the form of endless active scleral bands, electroactive ionic polymeric artificial muscle structures, electrochemically contractile endless bands of ionic polymers such as polyacrylonitrile (PAN), thermally contractile liquid crystal elastomer artificial muscle structures, magnetically deployable structures or solenoids or other deployable structures equipped with smart materials such as preferably piezocerams, piezopolymers, electroactive and eletrostrictive polymers, magnetostrictive materials, and electro or magnetorheological materials.

The invention discloses a processing method for improving quality of pork sliced ham. The processing method is characterized by comprising the steps of: thawing freezing-stored pork hindquarter, cutting, trimming, injecting, tenderizing, interval-tumbling for 6-10h, canning, smudging, steaming and cooking, cooling, slicing and vacuum-packaging. The pork sliced ham prepared by adopting the processing method has the characteristics of little steaming and cooking loss, small squeezing water loss rate and sterilization water loss rate, and good water holding capacity; and because the interval-tumbling process is carried out by adopting an aspiration tumbling mode under the conditions that meat loaves are in a vacuum state for a long time in a tumbling stage and a vacuum pump vacuumizes at intervals in a suspending stage, a preserving solution is more completely and effectively distributed in a muscle structure to be beneficial to the dissolution of salt soluble protein. Compared with the continuous tumbling mode, the interval-tumbling mode has the advantages that more salt soluble protein is generated, so that the binding among the meat loaves is facilitated; and during thermal processing, a stable protein gel structure is formed, thus the texture of the ham is improved.
