Abstract:
An apparatus for hydrating and extracting residual materials from a lens held in a concave well comprising:a shaft;multiple arms extending radially from a lower end of the shaft about a central axis in a star-shaped pattern, each arm including a fin extending therebelow such that multiple fins also extend radially with respect to said central axis, the fins including lower outer edges that converge and form a nozzle face, wherein outer tips of said arms extend radially from said central axis further than said fins extend radially from said central axis;a fluid transport passage extending through the shaft and terminating at an opening in the nozzle face; andat least one recessed channel formed in the nozzle face where the fins converge, each of said at least one channels extending from the opening in the nozzle face that forms a terminus of the fluid transport passage to a space between two adjacent fins.
