The lastest update for RSG is online.

Up to now we could see the SE pre-op vs SE post-op graphics by target SE with a widget, in the last update there is a new option called Independent. This option will now produce the graphic SE attempted vs SE attempted - SE achieved showing the accuracy of the SE refractive surgery for all the targets. This option is also available for the boxplots. Also now when uploading an excel, the targets are rounded to the closest 0.25. You can try it at the demo website here.





A large update for RSG has been released. Now the excel you can upload has 6 more columns for the keratometry, 3 for pre-op and 3 for post-op so you can see changes in the refractive and corneal astigmatism separately. Also some aesthetic changes to accomodate the increase in columns and the documentation has been updated. If you have excels for the previous version you can use them by inserting the 6 columns in the right place, you can leave them empty, just fill in the headers and it will work. You can test it here.





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.
