    Abstract: A system/method allowing hydrophilicity alteration of a polymeric material (PM) is disclosed. The PM hydrophilicity alteration changes the PM characteristics by decreasing the PM refractive index, increasing the PM electrical conductivity, and increasing the PM weight. The system/method incorporates a laser radiation source that generates tightly focused laser pulses within a three-dimensional portion of the PM to affect these changes in PM properties. The system/method may be applied to the formation of customized intraocular lenses comprising material (PLM) wherein the lens created using the system/method is surgically positioned within the eye of the patient. The implanted lens refractive index may then be optionally altered in situ with laser pulses to change the optical properties of the implanted lens and thus achieve optimal corrected patient vision. This system/method permits numerous in situ modifications of an implanted lens as the patient's vision changes with age.

  • Patent number: 8552134
    Abstract: A method of producing a water-absorbent resin of the present invention reduces amounts of a residual cross-linking agent and a residual surfactant, achieves high productivity, and improves physical properties of the resultant water-absorbent, such as absorption capacity, extractable polymer content, powder friction, and gel crushability. The method includes the steps of: polymerizing an aqueous monomer solution containing as a major component an acrylic acid monomer in the presence of a cross-linking agent; and drying the resultant polymer by heating, in which the cross-linking agent is a multifunctional (meth)acrylate cross-linking agent having polyethylene glycol structural units including a total of 6 to 200 ethylene oxide repeating units, and the aqueous monomer solution includes a mono(meth)acrylate compound having polyethylene glycol structural units in an amount of 0.1 to 30% by weight relative to an amount of the multifunctional (meth)acrylate cross-linking agent.
