Problems Remaining After Successful Keratoplasty for Keratoconus

Carney, Leo G. & Jacobs, Robert J. (1989) Problems Remaining After Successful Keratoplasty for Keratoconus. Clinical and Experimental Optometry, 72(1), pp. 22-25.



Keratoplasty procedures offer a proven increase in visual performance for most keratoconic patients. However, there can often remain subtle visual decrements. The visual functions of four subjects who had undergone uniocular penetrating keratoplasty with a successful visual outcome were evaluated by measurements of visual acuity, contrast thresholds for sinusoidal gratings, and contrast thresholds in the presence of a glare source. Contrast thresholds normally showed only slight elevations compared with those of age-matched controls. However, glare-sensitised thresholds revealed substantial visual decrements. These losses are not always present, are not easily predictable, and yet can be visually debilatating.

Search Google Scholar™

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.
