The 2023 Doyne Lecture-a cornea care system: evolution.

Blindness and visual impairment affect the quality of life of the individual and their family members. Corneal opacities are a key cause of vision loss around the world, especially in low-income and middle-income countries (LMIC). Corneal blindness and vision loss impacts every age group, and the risk factors and the causes are also varied. Socio-economic factors also play a significant role in its prevalence. Preventing, treating, and managing corneal conditions in LMIC contexts can therefore be quite complex and challenging. A model of eye care delivery developed and refined over the past four decades, the L V Prasad Eye Institute's cornea care system presents an example and a sense of hope. The model takes corneal care from world-class facilities in urban locations to rural locations, overcoming a variety of challenges. The initial breakthrough came with solving and ensuring a steady supply of corneal tissue. Then to training high-quality resources, building capacity, and investing in research that translates from the bench to the bedside. A variety of innovations, both in diagnosis and the operating theatre, have paved for improved outcomes that are tailored for the contexts in which this system operates. The institute envisions a future where its work further narrows the gap in eye care disparities and leads to life-changing impact in ophthalmic care of the cornea.
