The present invention provides a method for producing a silicone hydrogel having a high water content. The method comprises the following steps:

Method for enhancing water content of silicone hydrogel contact lens

A polysiloxane-based prepolymer of a three-dimensional network structure produced by hydrolysis-condensation of a first mixture having a tetra-alkoxysilane compound, an ethylenically unsaturated organosiloxane monomer, and a hydrophilic silicon-containing polyfunctional monomer. A hydrogel is prepared by polymerizing a second mixture having the aforesaid polysiloxane-based prepolymer, an acrylated silicon-containing monomer, and an ethylenically unsaturated hydrophilic monomer.

Polysiloxane-based prepolymer and hydrogel

An adjusting device for a chip adapter. The adjusting device comprises a main body having a plurality of adjusting holes into which testing pins of the adapter are inserted and a slider disposed on the main body and sliding perpendicular to the top surface thereof for easy removal the chip adapter without mis-alignment of testing pins.
