ABSTRACT:
A spherical swollen hydrophillic toric contact lens is converted into a planarized xerogel and stored and transported on a planar or moderately curved base provided with an angle scale in the range of 0 to 180 degrees. The base is formed to locate the lens above the center of the scale with the cylindric axis lying on the lines converting the 0 or 180 degrees with the center of the angle scale. A permeable cover capable of compressing the lens is placed over the lens causing the lens to assume the surface shape of the base in the xerogel state.
