From TFA:
> Aravind uses a two-pronged approach to addressing the lack of ophthalmologists: First, it enhances the efficiency of the existing staff. The hospital has an innovative “assembly line” operating theatre that allows a single surgeon to alternate between two fully prepared tables, each supported by dedicated instrument sets and nursing teams. This approach enables six to eight cataract operations per hour compared to an industry norm of one, while delivering clinical outcomes that even surpass those achieved in the UK’s National Health Service.
6–8x throughput is very impressive.
