PURPOSE: To check whether three months' follow-up is sufficient to determine endothelial cell loss after cataract surgery and whether this value depends on preoperative central endothelial cell density.
METHODS: A two-year prospective assessment of central endothelial cell density was done in 60 eyes after phacoemulsification. In 30 eyes a 3.5 mm corneal incision closed with a single crossed suture was made, and the other 30 had a 3.5 mm scleral tunnel no-stitch incision. Central endothelial cell density was measured before surgery and 1, 3, 6 months and 2 years after.
RESULTS: The mean rate of endothelial cell loss even two years after surgery was significantly higher than the physiological rate, amounting to 0.9% per year. There was no correlation between preoperative central endothelial cell density and postoperative cell loss.
CONCLUSIONS: Even two years' follow-up is not sufficient to establish the total endothelial cell loss after cataract surgery. The amount of cell loss does not depend on the preoperative density.
