Abstract
A punctum plug or lacrimal insert is constructed of a monolithic material, such that the punctum plug is configured to turn approximately 90 degrees upon insertion into a canaliculus of an eye. The punctum plug or lacrimal insert may include high-molecular-weight polysaccharide and added plasticizers.
Claims22
A punctum plug, wherein the punctum plug is constructed of a monolithic material comprising a high-molecular-weight polysaccharide and a plasticizer, such that the punctum plug is configured to turn approximately 90 degrees upon insertion into a canaliculus of an eye, wherein the high-molecular-weight polysaccharide includes a cellulosic polymer, and wherein the monolithic material is neither a tube nor a sleeve.
A punctum plug, wherein the punctum plug is constructed of an erodible monolithic material comprising a high-molecular-weight polysaccharide and a plasticizer, wherein the punctum plug is configured to be inserted into a canaliculus of an eye, wherein the high-molecular-weight polysaccharide includes a cellulosic polymer, and wherein the erodible monolithic material is neither a tube nor a sleeve.
