The number of glaucoma procedures, patients’ ages, and diagnoses made and success rates for the various glaucoma procedures performed are shown in Figures 4.1 to 4.6.
In the 2010 surgical audit, the overall success rate of trabeculectomy (TRAB) in primary glaucoma was 98.8%, whereas that of aqueous shunt surgery was 94.6%. The overall success rate of combined TRAB and cataract surgery was 98.5%.
Of the total success cases, 7.6% experienced an increase in IOP 12 months post-operation (TRAB : 5 [4.2%]; TRAB/cataract: 25 [10.3%]).

Of the glaucoma procedures performed in 2013, 488 of the 502 glaucoma surgery cases were audited (N – 452). In the independent annual surgical audit, success is defined as an achievement of an IOP ≤21 mm Hg at the end of the first post-operative year.
