Confocal microscopy of the corneas of long-term rigid contact lens wearers
Description
Slit scanning confocal microscopy (Tomey Confoscan P4) was used to evaluate the central cornea of 22 subjects who had been wearing rigid lenses on a long-term, daily wear basis. Anterior and posterior keratocyte densities appeared unaffected by rigid lens wear (P = 0.10 and 0.34 for anterior and posterior keratocyte densities, respectively). Subjects with a previous history of polymethyl methacrylate (PMMA) lens wear showed a reduction in anterior keratocyte density (AKD) (P < 0.0001) and an increased level of haze in the anterior stroma. This may represent previous hypoxic damage. Endothelial cell density (ECD) was unaffected by rigid lens wear (P = 0.36) although an increase in endothelial polymegethism was evident (P < 0.0001). Subjects who had only worn rigid lenses with no history of PMMA lens wear did not show an increase in endothelial polymegethism (P = 0.10). An increased number of microdot opacities compared to the non-lens wearing eye was apparent (P = 0.05). The number of microdot opacities induced by rigid lenses, as reported in this study, appears to be less than that reported by others in respect of soft lenses.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
