An alignment system for an ophthalmic instrument comprises an optical axis along which an operator can directly view the patient’s eye and the patient can fixate on a dark fixation target surrounded by a bright background that helps to illuminate the eye for operator viewing. A platen drives the blank through forming rails which fold the blank into a partially formed tray having bottom, end and side walls, and inside corner supports formed about the platen. In turn, the LID domains are interconnected via one or more GID switches. The system can include a pressure source to produce a sufficient fluid pressure substantially higher than the typical fluid pressure available from a facility installation.
