Visual Losses After Myopic Epikeratoplasty

Carney, Leo G. & Kelley, Curtin G. (1991) Visual Losses After Myopic Epikeratoplasty. Archives of Ophthalmology, 109(4), pp. 499-502.


The vision of seven patients who had undergone epikeratoplasty for myopia was evaluated by measuring their contrast sensitivity functions without and with the presence of a glare source. Compared with findings for a normal control population, these epikeratoplasty patients were found to have statistically significant contrast sensitivity losses. To evaluate the clinical relevance of these losses, the results were also compared with those for two other patient groups with abnormal corneal optics, seven radial keratotomy patients and seven keratoconus patients wearing rigid contact lenses. Contrast thresholds for the epikeratoplasty and keratoconus patients were similar and usually statistically indistinguishable, and their losses were far more profound than those of the radial keratotomy patients. The addition of glare did not alter this pattern of losses. The results document the extent of vision losses in these patients and suggest that increased intraocular light scattering is not a major contributor to the observed contrast sensitivity decrements.

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.
