ABSTRACT:
A pupil expander carrier has a block having a support surface. A first post extends upwardly from this surface in spaced relation to a first pair of spaced secondary posts. These three posts normally hold and stabilize a circular pupil expander during storage conditions. A second pair of spaced secondary posts extend upwardly from the support surface and are spaced from said first post a distance greater than the normal diameter of the pupil expander whereby when the pupil expander is moved to supporting engagement with the first post and the second pair of secondary posts, it is changed from a circular configuration to an elongated and generally rectangular configuration. A retention post extends outwardly from an edge portion of the block adjacent the second pair of secondary posts to engage the strap of the pupil expander just before removal thereof from the block. The forceps used to remove the elongated pupil expander from the carrier block have two elongated forcep tips which are rectangular in cross section and which have a width greater than the height thereof for insertion in the outer peripheral opening of the pupil expander.
