1. A method of non-randomly folding a flexible intraocular lens multiple times to have a diameter less than 50 percent of its original diameter, wherein the lens has an optical portion for alignment with pupil of an eye and a pair of opposed haptic portions for intraocular fixation, the method comprising the steps of:

  • mounting the lens on a rigid template having portions engaging the lens, which portions do not move either with respect to the lens or to one another;

    holding the lens with a first forceps;

    gripping the lens with a second forceps;

    folding the lens by pressing the lens up against at least one blade of a pair of blades of the first forceps while the lens is retained on the template to dispose the lens in a folded configuration completely between the blades of the first forceps;

    removing the blades of the second forceps from engagement with the lens; and

    squeezing the folded lens between the blades of the first forceps to minimize the size of the folded lens whereby the folded lens may be inserted through a surgical incision of minimal length in the eye.
