The L V Prasad Eye Institute: A comprehensive case study of excellent and equitable eye care

Global healthcare delivery systems are facing ever-increasing challenges on multiple fronts. The need to study and define successful models of care delivery systems has become increasingly important. The L V Prasad Eye Institute (LVPEI) has a distinctive eye care delivery system offering rich lessons at many operational levels. The system has been developed on the basis of LVPEI's foundational public eye health study, and follows a complexity-driven (dependent on disease complexity) clinical care system forming a five-tier pyramidal model - at the apex is the quaternary care centre at Hyderabad, followed by increasing numbers of tertiary, secondary or community, primary, and rural eye care centres, where the revenue from paying patients covers free-care via an economic cross-subsidy. This has achieved a level of scale, efficiency, social impact, and clinical and scientific innovation rarely seen in a single health system. Building on the foundational principles of this pyramidal care with a robust economic cross-subsidy model, LVPEI has seamlessly established successful professional, academic, and educational systems that combine innovation, scientific discovery, and the development of in-house technologies focused on improving service quality and clinical decision making. In this case study, we show that all elements of the LVPEI model are practical and may be applicable to academic medical centres in diverse healthcare settings; currently, this is being tested in Liberia, West Africa.
