Can I just draw to your attention “Simultaneous Bilateral Cataract Surgery with IOL Implantation in Children in Kenya. Gradin D, & Mundia D, Journal of Pediatric Ophtghalmology and Strabismus 2012; 49: 139-144.”
The summary I have read quotes cost analysis for 48 children operated on aiwth ISBCS compared to 48 DSBCS (next day), with costs for the ISBCS group ($274/child) being 20% lower than for the DSCBCS group ($344/child). They comment that AC fibrin was common inboth groups, but that there was no excess in the ISBCS cohort.
MY OPINION: I think that we recognise that paediatric surgeons have been doing ISBCS quietly more commonly than is recognised. This paper extends this to the developing world. Since it is in the developing world that the cost strictures of healthcare are most critical, it may well be that ISBCS will develop rapid acceptance in this area.
