Textured contact lens package

Abstract

A container for storing a silicone hydrogel contact lens in a liquid, having a bowl portion with a radius such that the radius of the lens is from about 85 percent to about 100 percent of the inner surface radius. The bowl portion has an outer section which is defined by a radius larger than the inner surface radius. Furthermore, the bowl portion has a roughness sufficient to maintain capillary attraction of the lens to the bowl portion but preventing adhesion of any portion of the front surface of the lens to the bowl portion.

1 - 7 . (canceled) 
   
   
       8 . A process of manufacturing a container for storing a silicone hydrogel contact lens in a liquid, the silicone hydrogel contact lens having a base surface defining a base curve equivalent radius and a front surface, comprising the steps of:
 providing a mold used to manufacturing the container, wherein the container having a base portion, a bowl portion formed integral with the base portion for containing the liquid and the contact lens, the bowl portion including a lens seating section having an inner surface defined by a radius, the base curve equivalent radius being from about 85 percent to about 100 percent of the inner surface radius, and an outer section between said lens seating section and said base portion,   roughening the surface of the mold defining the inner surface of the bowl portion, injection molding the container from a polymeric material.   
   
   
       9 . A process according to  claim 8 , wherein the surface of the mold defining the inner surface of the bowl portion is roughened by electron discharge machining or sandblasting. 
   
   
       10 . A process according to  claim 8 , wherein the surface of the mold defining the inner surface of the bowl portion is roughened to a Charmille No. of 16 to 30. 
   
   
       11 . A process according to  claim 8 , wherein the surface of the mold defining the inner surface of the bowl portion is roughened to a Charmille No. of 18 to 26. 
   
   
       12 . A process according to  claim 8 , wherein the polymeric material is polyethylene or polypropylene.
