Abstract: A rebound tonometer is improved by providing a tilt signal from a tilt sensor of the rebound tonometer to a signal processor of the rebound tonometer, and configuring the signal processor to apply a tilt correction factor to a basic IOP measurement value calculated by the signal processor to provide a final IOP measurement value, wherein the tilt correction factor depends on a tilt direction and a degree of tilt indicated by the tilt signal. The final reported IOP measurement value takes into account gravitational effects on the probe due to tilt. As a result, measurements made at relatively small tilt angles are now usable, thereby improving efficiency. A corresponding rebound tonometry measurement method, and a method of calibrating a rebound tonometer for tilt correction, are also disclosed.

Abstract: A mapping lensmeter is characterized by a macro-imaging system configured to detect a macro-image of the lens. The macro-image of the lens may be superimposed with a map of the lens indicating local refractive power at various zones of the lens to form a composite image of the lens. The composite image may include a pupil marking made on the lens.

Abstract: A case for containing at least partly compressible articles comprises an outer shell which can be opened and closed and defines a cavity therewithin, and having an attachment member or members secured to the outer shell inside the cavity. A number of compression bags are contained within the shell cavity and are detachably retained by the attachment members such as to maintain a relative position with respect to one another within the case. Each of the compression bags includes is air impervious when sealed and can received the articles within the enclosure defined therein, and includes a one-way valve allowing air to be removed from the enclosure within the bag, thereby creating at least a partial vacuum in the enclosure which compresses the articles within the bag.
