IOL insertion apparatus and method for making and using same
View Patent ↗Apparatus for inserting intraocular lenses (IOLs) into eyes include a hollow tube including a material and having an interior wall defining a hollow space through which an IOL is passed and an outlet through which the IOL is passed from the hollow space into an eye, and a lubricity enhancing component physically secured to said hollow tube and concentrated at or near the interior wall in an amount effective to facilitate the passage of the IOL through the hollow space.
1. A method of making an intraocular lens (IOL) insertion apparatus comprising:
providing a polypropylene insertion tube comprising a hollow tube having an interior wall defining a hollow space through which an intraocular lens is passed and an outlet through which said intraocular lens is passed from said hollow space into an eye; and
securing a coating to said interior wall of said hollow tube, wherein the coating comprises polyvinylpyrrolidone, wherein the polyvinylpyrrolidone is physically secured, other than by covalent bonding, to said interior wall and is effective to facilitate the passage of said intraocular lens through said hollow space and into an incision of 3.5 mm or less.
2. The method of claim 1 , further comprising the step of exposing the polypropylene insertion tube to plasma.
3. The method of claim 2 , wherein the polypropylene insertion tube is exposed to plasma before the coating is secured to the interior wall.
4. The method of claim 2 , wherein the polypropylene insertion tube is exposed to plasma after the coating is secured to the interior wall.
5. The method of claim 1 , wherein the hollow tube is tapered through at least a portion thereof.
6. The method of claim 1 , wherein the coating further comprises a second polymer component covalently bonded to the interior wall of the hollow tube.
