Cataract disease is the leading cause of global blindness. Even though cost-effective treatment modalities are available, challenges to effective implementation strategies pose a significant obstacle to initiatives to alleviate this condition. In this era of increasing costs and aging populations, cataract intervention programs should re-engineer strategies to ensure that the resources are accessible and efficiently utilized by all stakeholders.
In spite of the significant advances in the field of ophthalmology, blindness continues to be widely prevalent. Cataract disease is the leading cause of blindness, especially in developing countries. This chapter will describe the global magnitude of cataract blindness, the different types of the surgical interventions available, the challenges associated with these interventions, and the economic implications of treatment.
