Audit and Research

The department’s work is benchmarked against the international “best-in-class”. The types of surgeries performed, and the success rates are shown in Figure 6.1 to 6.6.


Of the patients undergoing ptosis surgery, 97% expressed satisfaction with the surgical results in 2014 (91% achieved good symmetry or no-more than 1mm asymmetry).

A study by McCulley et al. (2003) demonstrated that 23% of patients had imperfect eyelid position by subjective patient grading in a comparison of several institutions in the United States (McCulley, Kersten, Kulwin & Feuer, 2003). The British Oculoplastic Surgery Society National Ptosis Survey demonstrated, in a 1-year prospective study of ptosis surgery results, a 57% success rate and a 39% partial success rate after assessing an interlid margin reflex distance difference <2mm and the symmetry of lid contour (Scoppettuolo, Chadha, Bunce, Oliver, & Wright, 2008).


Surgical audits from 2010 demonstrated that 98% of all cases achieved good lid-globe apposition for entropion correction.



Of the patients undergoing blepharoplasty surgery, 82.4% rated their experience as satisfactory or excellent. The average and median ratings were 7 out of 10.
