Abstract: Certain aspects are directed to an ophthalmic specialty instrument configured to allow patients to treat MGD and other dry eye conditions themselves which is easy to operate and more effective. The ophthalmic specialty instrument comprises a main body of two arms with a distal end and a proximal end; wherein the two arms are pivotably coupled to a common connection point at the proximal end and a pair of angled and slightly wedged pressure plates are attached to the distal end of the two arms; wherein an exfoliating member is also attached to the proximal end; and wherein the pressure plates are angled downwardly and outwardly from the longitudinal planes of the arms and have gentle radius of curvature that match the curvature of eyelids to facilitate a substantially 90° approaching angle to the eyelid margin as opposed to making contact with the eyelids tangentially.

Abstract: A method for coating an aluminum alloy heat exchanger includes subjecting at least one surface of the heat exchanger to a pre-treatment process including cleaning; conversion coating the at least one surface of the heat exchanger with a trivalent chromium compound; and subjecting the at least one conversion coated surface to an electro-coating in an aqueous solution containing an organic corrosion inhibitor.
