We evaluated the morphology and permeability of corneal epithelium before and 1 month after suture removal for keratoplasty in 34 eyes. No significant changes were noted in rose bengal staining scores, corneal sensitivity, tear film break-up time or tear function before and after suture removal. Elongated epithelial cells were observed in 15 eyes before and in 4 eyes after suture removal. The mean area of epithelial cells showed no changes. Extremely enlarged epithelial cells in 8 eyes showed reduction in size after suture removal. While mean epithelial permeability to fluorescein showed no changes, corneal permeability with highly permeable epithelial cells improved after suture removal. The patients reported reduced foreign body sensation and easiness in opening the eyes. The findings show that suture removal is beneficial in improving morphology and permeability of impaired epithelial cells.
