Abstract In 1991 Wesley-Jessen introduced custom patterns in their DuraSoft Opaque soft contact lenses. Double printing of the dot matrix like tint pattern, black underprinting, clear or black pupils in two diameters, and combinations of all the various options have allowed for an outstanding custom product. Patients with opaque or scarred corneas, irregular pupils, aniridia, etc. have benefited greatly from the cosmetic enhancement such lenses provide. The black pupil lens has also been used to help diplopic patients. While cosmetically excellent, these lenses can also induce corneal changes. These relatively short-lived changes have been reported with annular tinted lenses, and have been termed corneal imprinting. This poster reports the findings of an investigation into the type of imprints which can be seen with the various products. Using the TMS and EyeSys corneal topography instruments, color topographical representations of the corneal imprinting were obtained by comparing the topography before and after lens wear. These difference mappings reveal dramatic corneal imprints after wearing various custom tinted lenses in some patients. This poster presents both photographic documentation of the considerable cosmetic enhancement these lenses, as well as, the mappings of the corneal imprint induced. Practitioners need to be aware that if the lens is used as an occluder, there may be enough spectacle blur present after lens wear to prevent alternating the occlusion during a single day. An example of just such an attempt will be documented.
