Specialist Practice results

As part of a systematic quality programme I routinely monitor the results of my cataract surgery. The results of a recent audit are given below. Parts of this audit, relating to control of astigmatism, were presented at a national cataract and refractive surgery (UKISCRS) meeting. National bench-mark figures, where available, are given in blue.

Total number of consecutive patients   102
Age   Mean 75 yrs (range 43-91) (76 yrs)
Sex   Male 40% (36%)

Pre-existing pathology (conditions likely to compromise final vision eg macula degeneration, diabetic retinopathy, amblyopia)   25% (15%)

Proportion high risk (pre-existing eye problems likely to add risk to cataract surgery eg high myopia or hyperopia, pseudoexfoliation) 26%

Post op unaided visual acuity (measurement of visual clarity following surgery without any correction with glasses/contact lenses.  In most cases correction with glasses/contact lenses will increase the vision further.  The higher the denominator figure the less clear is the vision.  6/6 vision is considered very good, legal driving vision equates to around 6/10)
                      > 6/6                51% (overall)   59% (no pre-existing eye pathology)
                      >6/9                 82% (overall)   93% (no pre-existing eye pathology)
                      >6/12               89% (overall)   99% (no pre-existing eye pathology)

National benchmark figures are for best corrected visual acuity ie using glasses/contact lenses where necessary, a significantly lower standard:

                     >6/12               86% (overall)   96% (no pre-existing eye pathology)

Proportion within 1D SE (measure of how close the actual refractive outcome is to the intended) 93%

Proportion with <1Dcyl (measure of amount of residual astigmatism following surgery)  65%

Reduction of astigmatism with LRIs (additional, planned small corneal incisions that reduce pre-existing astigmatism)  Mean 1.49D
Proportion 67%

Capsule rupture (damage to membrane that supports new lens) 0% (2.68-4.4%)

Endophthalmitis (post-operative infection inside the eye)            0% (0.03-0.14%)
