Abstract
In apparatus for optical lens forming and displacing, the combination comprises body structure including lens deforming surfaces to receive a lens therebetween and to form the lens into multiple folds; multiple prongs to engage the lens folds; a plunger to displace the prongs endwise of and relative to surfaces and to discharge the folded lens endwise from the structure; and the structure including guide surfaces to cam the prongs toward one another to reduce the lens cross-section being displaced from the structure.

In apparatus for optical lens forming and displacing, the combination comprising:
- a) body structure including lens deforming surfaces to receive a lens therebetween and to form the lens into multiple folds,
- b) multiple prongs to engage the lens folds,
- c) plunger means to displace the prongs endwise of and relative to said surfaces and to discharge the folded lens endwise from said structure,
- d) said structure including guide surfaces to cam the prongs toward one another to reduce the lens cross-section being displaced from said structure.
In the method of optical lens forming and displacing, the steps that include:
- a) providing structure including lens deforming surfaces to receive a lens therebetween and to form the lens into multiple folds,
- b) said structure including multiple prongs to engage the lens folds,
- c) providing and operating plunger means to displace the prongs endwise of and relative to said surfaces to discharge the folded lens endwise from said structure,
- d) said structure provided with guide surfaces to cam the prongs toward one another to reduce the lens cross-section being displaced from said structure.
The method of deforming a flexible artificial lens, preparatory to insertion into the eye, the lens having a peripheral edge, that includes the steps:
- a) advancing the lens edgewise in a longitudinal direction,
- b) and progressively compacting the lens in a lateral direction, during said advancing.
