Cataract & Clarivu (Refractive Lens Exchange) Surgery Benchmark Complication Rate
In all cataract and lens replacement surgeries – significant damage to the thin membrane that encases the natural lens and ultimately also acts as a support pocket within which a lens implant is usually is positioned – called Posterior capsular rupture with or without vitreous presentation is widely recognised as the surgical index benchmark for cataract and lens replacement surgery. What does this mean?
- A complication that requires some additional operative time to manage. Eyes that experience this complication are a little more likely to develop additional post operative complications such as infection (endophthalmitis), retinal detachment and a condition called macular oedema.
- Such eyes are therefore at a slightly higher chance of developing less than ideal vision outcomes.
It is worth noting however that the vast majority of eyes that experience this complication will still end up with perfectly normal eyesight.
- A lower vitreous presentation rate is therefore generally regarded as an important indicator of surgical performance.
Because cataract surgery with lens implantation and Lens exchange surgery (purely for vision correction purposes) are identical surgical procedures we have collated the outcomes to produce the figures detailed below. This index complication rate in my cataract/lens replacement practice is 0.3% in this most recent recent analysis.
99.7% of all such procedures were essentially routine and uneventful !
100% of Clarivu / Refractive lens exchange procedures were essentially routine and uneventful during the most recent two year long continuous analysis!
Benchmark Complication Rate Comparison
A benchmark complication rate of 0.3% sounds incredibly low – and it is – but how does it compare with peer reviewed published outcomes?
The graph below shows our most recent results from a two year long continuous analysis -set against recently published outcomes spanning the last decade or so.
