Table 1 Results of number of enucleations performed by respondents in 2003, with a theoretical calculation for the minimum number of procedures in each group.

Number of enucleations performed in 2003	Median number of operations	Number of consultants	Derived theoretical total number of operations for each group
<3	1.5	209	313.5
3–6	4.5	29	130.5
7–10	8.5	14	119
11–15	13	2	26
16–20	18	1	18
21–30	25.5	2	51
>30	30*	2	60
Total			718

Calculation was derived by multiplying the median number of operations by each group by the number of consultants in each group.

*For the >30 group, it was not possible to use the median number, so 30 was used in the calculation.
