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.
