Graph 3 illustrates change in various corneal lamellae with time
Serial change in DSEK lamella with time
Correlation between a) central corneal thickness and best spectacle corrected visual acuity (BSCVA) 6 months after DSEK and b) between peripheral thickness and BSCVA
Pearson correlation coefficient r = 0.54
Pearson correlation coefficient r = 0.39
