Abstract

An adapter to be applied in contact with an anterior corneal surface. The adapter includes a contact glass portion having a corneal contact surface curvature that is flatter than the undeformed anterior corneal surface. When the contact glass is applied the cornea assumes a deformed state corneal curvature that is parallel to the flatter corneal contact surface curvature. A mount portion circumferentially surrounds the contact glass portion and defines a suction duct that is structured to secure the adapter to the cornea by negative pressure when the suction duct is brought into contact with a surface of the eye surrounding the contact glass portion. The suction duct is partially defined by a peripheral edge of the mount that extends outwardly away from the mount portion and toward but not intersecting or extending beyond a geometric continuation of the corneal contact surface curvature.
