Abstract:
1. An apparatus for wetting and coating ophthalmic lenses, comprising: at least one tank adapted to contain a liquid solution; a handling system for sequentially moving a lens and the solution in relation to each other; and a master control module coupled to said handling system, and configured to control execution of the wetting of the lens in accordance with a wetting profile, wherein the wetting profile comprises data including a submersion speed/acceleration profile and a removal speed/acceleration profile based on the incremental vertical lens surface slope with respect to the surface of the liquid solution and the wetting profile also comprises data for differently varying the withdrawal speed for a top section of the lens based on a correction factor for gravity; and wherein said wetting profile comprises instructions to move the lens with respect to the liquid solution to obtain a lens coating with uniform thickness and improved quality.
