Devices and methods to simulate an ocular environment

Abstract

Methods and devices used to simulate the use of an ophthalmic lens contained in an ocular environment are disclosed herein.

1 . An apparatus for testing an ophthalmic lens comprising a male mold and a female mold,
 wherein said male mold comprises a convex testing surface, an outer male surface, male seating ridge extending from the perimeter of the convex testing surface, and an aperture extending from said outer male surface to said convex testing surface,   wherein said female mold comprises an outer female surface a concave testing surface, female seating ridge extending from the perimeter of the concave testing surface, and an aperture extending from said concave testing surface to said outer female surface,   wherein when the male mold and the female mold are mated, the male seating ridge sits on the female seating ridge and creates a testing area between the male convex testing surface and the female concave testing surface.   
     
     
         2 . The apparatus of  claim 1  wherein said convex testing surface comprises at least one radial groove extending from the aperture to the perimeter of the convex testing surface and at least one latitudinal groove that intersects the at least one radial groove. 
     
     
         3 . The apparatus of  claim 2  wherein the convex testing surface comprises at least four radial grooves. 
     
     
         4 . The apparatus of  claim 2  wherein the convex testing surface comprises at least four latitudinal grooves. 
     
     
         5 . The apparatus of  claim 1  wherein said concave testing surface comprises at least one radial groove extending from the aperture to the perimeter of the concave testing surface and at least one latitudinal groove that intersects the at least one radial groove, 
     
     
         6 . The apparatus of  claim 5  wherein the concave testing surface comprises at least two radial grooves. 
     
     
         7 . The apparatus of  claim 5  wherein the concave testing surface comprises at least four latitudinal grooves. 
     
     
         8 . The apparatus of  claim 5  wherein the concave testing surface comprises at least four radial grooves. 
     
     
         9 . The apparatus of  claim 2  wherein said concave testing surface comprises at least one radial groove extending from the aperture to the perimeter of the concave testing surface and at least one latitudinal groove that intersects the at least one radial groove. 
     
     
         10 . The apparatus of  claim 9  wherein the convex testing surface comprises at least two radial grooves and at least three latitudinal grooves and the concave surface comprises at least two radial grooves and at least three latitudinal grooves.
