摘要： A biocompatible poly(ethylene oxide) gel implant and method for production which can be injected into the human body for tissue replacement and augmentation. The implant is prepared by dissolving a sample of essentially pure poly(ethylene oxide) in a saline solution in a sealed canister, removing all free oxygen from the container and replacing it with an inert gas, such as argon, and irradiating the canister with a gamma ray source to simultaneously crosslink the polyethylene oxide while sterilizing it. The gel can then be placed into a syringe and injected into the body.

摘要： The present invention provides a surgical technique and instrument kit that allows for subtle modification of the corneal curvature by interlamellar injection of a synthetic gel at the corneal periphery while sparing the optical zone. The gel viscosity, volume and disposition within the surgical annular track as well as the diameter of the track, width, depth, and location are all parameters in the refractive change obtained. Following ultrasonic pachymetry performed centrally and at a selected wound entrance located about 2.5 to 3.5 mm from the apex, a one millimeter or so wide, about 75-85% corneal thickness depth radial incision is performed with a micrometric diamond knife adjusted to about 86% corneal thickness. Inserted through the partial-depth incision, a corkscrew-like dissector or helicoidal spatula forms a 360.degree. annular track centered about the apex. A transparent gel is manually injected through the incision, filling the annular channel. Using a surgical keratometer mounted to an operation microscope, the final corneal power is adjusted by massaging and removing the gel as necessary during the primary procedure or subsequent procedures, as the GIAK technique is reversible.
