PACHOMETRIC STUDY ON THE INFLUENCE OF CORNEAL ENDOTHELIAL VITAL STAINING

The corneal thickness was measured in 114 cases prior to cataract extraction. On the second postoperative day a 15 per cent increase of the thickness was noticed, and on the sixth postoperative day a 9 per cent increase. At a follow‐up 6 to 12 months later the thickness was as before the operation. Half of the eyes were vital‐stained during the operation by filling the anterior chamber with 0.1% trypan blue. Such staining has no harmful effect on the corneal endothelium, assessed by the corneal thickness and by occurrence of corneal epithelium oedema.
