Abstract
A lacrimal insert includes a body defining a reservoir, and a head provided at an end of the body and closing the reservoir. The body is made from a material impermeable to the medication while the head is made from a permeable material adapted to release the medication from the reservoir to the eye at a determinable rate. In one manufacture, the body of the insert is molded and includes a hole at a tip end; the head is molded onto the body; the medication is injected into the insert through the tip end hole; and the tip end is sealed. The portion of the insert at which the medication is released is precisely fabricated in order to control release of the medication, and the reservoir is filled and then closed away from the area of medication permeability.
