Form Fit™ truly is a one size fits all plug. Once inserted into the punctum, Form Fit™ hydrates over a 10 minute period. As it hydrates, Form Fit™ increases in size until it completely fills the vertical canalicular cavity to form a perfect fit.
The Form Fit™ plug is made of a hydrogel material that expands into a soft, pliable, gelatinous material when it contacts tear film. The Form Fit™ is easily removable by flushing saline solution through the punctal opening.
