In the clinical study The Royal College of Ophthalmologists’ National Ophthalmology Database study of cataract surgery: report 1, visual outcomes and complications the aim is to describe the outcomes of cataract surgery in the United Kingdom. The data is of 118 114 eyes from 127 685 patients that underwent cataract surgery between 2006 and 2010.
The first table shows the ocular co-pathologies in the operated eye by grade of the operating surgeon, as the number of co-pathologies and by co-pathology. About the number of co-pathologies in the operated eye I made the following graphic:
We can easily see that consultant surgeons have more eyes with co-pathologies than the independent non-consultants and the trainees. The Y axis distance is not linear as you may have noticed, it's the cubic root of the value. The following graphic shows the recorded co-pathologies:
This could be a good indication of what co-pathologies we can expect in cataract surgery in the UK. The second table shows the intraoperative complications in the operated eye by grade of the operating surgeon, here is the graphic, you can click on it to see a larger version:
We can see that the most common complication is the posterior capsule rupture and/or vitreous loss. Because of the number of operated eyes this is a nice benchmark for a surgeon to see how you are doing in your practice.
