Significance defined as p < 0.05. Significant values in bold.
(A) LogMAR gain: No difference between ethnicities and LogMAR gain. No difference between ANP and other operator grades for LogMAR gain in VA other than residents who had significantly higher LogMAR gain than ANP (p = 0.020). Ocular co-morbidities and increased Age were both strongly correlated to reduced LogMAR gain (p < 0.001 in both instances).
(B) Repeat YAGPC: No difference in ethnicity and repeat YAGPC rate. SAS (p = 0.029), residents (p = 0027), fellows (p = 0.041), and consultants (p = 0.012) all had significantly higher repeat YAGPC rate compared to ANP. Increased age had reduced YAGPC rate (p < 0.001).
