Less might be more: are disposable gloves and gowns necessary for cataract surgery?

3. The mean Oxford’s fluorescein score was 1.2 in minimal-to-moderate NK eyes, and 2 in moderate-to-severe NK eyes. Mean corneal sensation was lower in NK group (2.7 0.9 versus 5.9 0.1; p < 0.001). In vivo confocal microscopy (IVCM) demonstrated a significant decrease in the mean total number, length and density of subbasal nerve plexus in NK eyes compared to non-NK eyes (Fig. 1). Neurotrophic keratitis (NK) was minimal to moderate with punctuate epithelial keratopathy, and we never noticed recurrent epithelial erosions or persistent epithelial defect in the affected eyes. The preganglionic topography of the trigeminal nerve lesion could therefore explain that NK induced by CCF was not severe. In addition, IVCM demonstrates corneal nerve impairment in patients with low corneal sensitivity and could therefore be considered as an interesting tool to assess NK in patients with an elevated venous pressure in the cavernous sinus such as in CCF.
