Claims19
An apparatus for cleaning the tips of ophthalmic lens transfer tips, comprising a wash station and a movable arm
- wherein the wash station comprises a first wall, a second wall, and a hollow channel connecting the first wall and the second wall
- wherein the first wall comprises an inner first surface and an outer first surface
- wherein the inner first surface comprises at least two apertures, each of which extends from the inner first surface through the first wall to the hollow channel
- wherein the second wall comprises an inner second surface and an outer second surface
- wherein the inner second surface comprises at least two apertures, each of which extends from the inner second surface through the second wall to the hollow channel,
- wherein the hollow channel extends from the outer first surface through the inner first surface, the inner second surface terminates at the outer second surface.
- wherein the movable arm comprises at least two ophthalmic lens transfer tips.
A method of removing debris from ophthalmic lens transfer tips comprising
- forcing water through the hollow channel of a wash station comprising a first wall, a second wall, and a hollow channel connecting the first wall and the second wall
- wherein the first wall comprises an inner first surface and an outer first surface
- wherein the inner first surface comprises at least two apertures, each of which extends from the inner first surface through the first wall to the hollow channel
- wherein the second wall comprises an inner second surface and an outer second surface
- wherein the inner second surface comprises at least two apertures, each of which extends from the inner second surface through the second wall to the hollow channel,
- wherein the hollow channel extends from the outer first surface through the inner first surface, the inner second surface terminates at the outer second surface, and
- moving the lens transfer tips between the first inner surface and the second inner surface.
The method of claim 14 wherein moving comprises movement along the horizontal axis.
An apparatus for cleaning the tips of ophthalmic lens transfer tips, comprising a movable arm and a wash station comprising a first wall and a second wall
- wherein the first wall comprises an inner first surface and an outer first surface
- wherein the inner first surface comprises at least two apertures, each of which extends from the inner first surface through the first wall to a first wall port
- wherein the second wall comprises an inner second surface and an outer second surface
- wherein the inner second surface comprises at least two apertures, each of which extends from the inner second surface through the second wall to a second wall port,
- wherein the movable arm comprises at least two ophthalmic lens transfer tips.
A method of removing debris from ophthalmic lens transfer tips comprising forcing water through the wall ports of a wash station comprising a first wall and a second wall
- wherein the first wall comprises an inner first surface and an outer first surface
- wherein the inner first surface comprises at least two apertures, each of which extends from the inner first surface through the first wall to a first wall port
- wherein the second wall comprises an inner second surface and an outer second surface
- wherein the inner second surface comprises at least two apertures, each of which extends from the inner second surface through the second wall to a second wall port,
- moving the ophthalmic lens transfer tips between the inner first surface and the inner second surface.
