    摘要: Reduced trauma medical implants and methods for their use are disclosed wherein at least a portion of the implant is formed of a stretch-crystallizable elastomeric material formulated to exhibit the property of stretch crystallization upon substantial elongation of the implant to form stable, small-incision implant configurations having at least one dimension substantially reduced for insertion through a surgical incision that is small relative to the incision size necessary to implant the unstretched implant. Exemplary embodiments include intraocular implants formed of optically clear, high refractive index stretch-crystallizable silicone elastomers formulated to stretch crystallize at near ambient temperatures upon elongations greater than or equal to 300% and to recover their original configuration immediately upon exposure to body temperature following implantation.

    摘要: Polysiloxanes suitable for the preparation of intraocular lenses by a crosslinking reaction, having a specific gravity of greater than about 1.0, a refractive index suitable for restoring the refractive power of the natural crystalline lens and a viscosity suitable for injection through a standard cannula are provided. Moreover, injectable intraocular lens material based on these polysiloxanes and methods of preparing intraocular lenses by direct injection into the capsular bag of the eye are also disclosed.
