Detailed summary of the cost of every aspect of surgical and outpatient management in the first 6 months after the operation. Numbers represent the average total cost per patient of each specific activity and are expressed in £ ± standard deviation. In square brackets there are the interquantile ranges. Numbers in round brackets represents the average number of units per group. E.g.in the DSAEK surgeon group, on average we performed 2.6 OCT scans for each patient, with a cost per scan of £67 (average total cost per patient: £67 x 2.6 = £174).
