Abstract
A method for treating an external eye condition due to a deficiency of tears as shown. The method includes the steps of testing the eye to determine if a tear deficiency exists. If a tear deficiency is determined to exist, the method includes the step of placing a removable implant being formed of a dimension to pass through the punctum opening and canaliculus of an eye and having an elongated central member including a central axis and a pair of ends wherein one end of said pair of ends has a collapsible flared section having a substantially uniform shape therearound and including means for enabling said collapsible flared section to be uniformly collapsed relative to the central axis in response to the application of force on the collapsible flared section in a direction to collapse the same and urge the collapsible flared section into a collapsed position into and past the punctum opening and into a selected location within the canaliculus causing the collapsible flared section to be collapsed within and to occlude the canaliculus.
