Mentor’s Comment: UPSC Mains have always focused on ‘Inclusive Healthcare Infrastructure’ (in 2020), ‘Effective Implementation of Healthcare Policies’ (in 2017), ‘Universal Health Coverage Programs’ (in 2015).
Corneal blindness is a significant public health issue in India, contributing to approximately 15% to 20% of total blindness cases. With an estimated 1.2 million people affected and 20,000 to 25,000 new cases emerging annually, the urgency for effective solutions is paramount.
Today’s editorial explores the current challenges and proposes a comprehensive approach to address corneal blindness in India. This content can be used to present ‘Public Health challenges’ and to suggest some ‘innovative solutions to address Public Health’ in India.

Why in the News?
The Report titled “India’s corneal blindness crisis” published by India Today, highlights the increasing incidence of corneal blindness, particularly in rural areas, and discusses the contributing factors such as limited access to healthcare and a shortage of donor corneas.
| What are the key findings from these reports? • Rising Incidence: Corneal blindness is increasing in India, with estimates of 20,000 to 25,000 new cases annually. This condition accounts for approximately 7.5% of total blindness cases in the country, significantly impacting rural populations where access to eye care is limited. • Demographics and Causes: The causes of corneal blindness have shifted from infectious diseases like keratitis to eye trauma and complications. Factors such as vitamin A deficiency, poor hygiene, and delayed medical interventions exacerbate the problem, particularly affecting children and working-age adults in rural areas. • Healthcare Disparities: Many individuals in rural regions lack access to quality eye care services, leading to irreversible corneal damage before they seek help. There is a notable gap in training and resources for healthcare providers, limiting their ability to effectively manage and treat corneal conditions. • Shortage of Donor Corneas: Despite a demand for around 100,000 corneal transplants each year, only about 25,000 to 30,000 corneas are donated annually. This shortage poses a significant barrier to treating those affected by corneal blindness. • Policy Considerations: Indian policymakers are considering implementing a ‘presumed consent’ model for organ donation to increase the availability of donor corneas. This approach aims to address the critical shortage and improve access to necessary treatments. |
What are the primary causes and current statistics of corneal blindness in India?
- Occupational Hazards: Injuries, particularly in industrial and agricultural settings, are increasingly recognized as a leading cause of corneal blindness. This shift highlights the impact of occupational hazards on eye health.
- Historically, infectious diseases such as keratitis and trachoma have been significant contributors to corneal blindness.
- However, the focus has shifted towards eye trauma and complications as major causes in recent years.
- Nutritional Deficiencies: Widespread vitamin A deficiency is another critical factor exacerbating the incidence of corneal blindness, particularly among vulnerable populations such as children and working-age adults.
- Healthcare Access Issues: Limited access to quality eye care services, especially in rural areas, leads to delayed treatment for conditions that could be managed effectively if addressed early.
- Poor Hygiene and Delayed Interventions: Poor hygiene practices and delays in seeking medical help contribute to the worsening of corneal conditions, often resulting in irreversible damage.
| Current Statistics • Corneal blindness affects approximately 1.2 million people in India. • The country sees an estimated 20,000 to 25,000 new cases of corneal blindness each year. • Corneal blindness accounts for around 7.5% of the total blindness burden in India. • Children and working-age adults in rural areas are particularly susceptible due to malnutrition and frequent injuries, while elderly individuals face risks from degenerative eye conditions. |
What are the barriers to effective treatment and prevention of corneal blindness?
- Shortage of Donor Corneas: There is a significant gap between the demand for corneal transplants (estimated at 100,000 annually) and the actual number of donor corneas available (around 25,000 to 30,000). This shortage limits the ability to treat those suffering from corneal blindness effectively.
- Healthcare Disparities: The distribution of specialized corneal services is uneven across India, with underserved regions lacking adequate facilities for the timely management of corneal diseases.
- More trained corneal surgeons are needed to meet the annual transplant targets.
- Although the Cornea Society of India has over 1,000 members, the exact number of surgeons performing keratoplasty regularly is unclear. This gap in training and availability affects surgical outcomes.
- Data Gaps: Comprehensive data on the prevalence of corneal blindness and the number of individuals who could benefit from transplantation are lacking. Establishing a national registry for corneal blindness and transplants is essential.
- Preventable Causes: Many cases of corneal blindness are avoidable through preventive measures such as addressing vitamin A deficiency, improving hygiene practices, and providing timely medical interventions for infections and injuries.
- Public Awareness and Myths: Lack of awareness about eye health and misconceptions surrounding eye donation hinder corneal donation efforts. Myths about eye color change after donation or beliefs that only young people can donate deter potential donors.
What comprehensive strategies can be implemented?
- Public Awareness and Education:Min of Health and Family Welfare (MoHFW) can lead nationwide awareness campaigns about eye health, corneal blindness, and the importance of eye donation.
- Local health departments can conduct community outreach programs in schools and villages to educate people about eye care and the significance of corneal donation.
- Enhancing Healthcare Access: The National Programme for Control of Blindness & Visual Impairment (NPCBVI) under the MoHFW, is responsible for improving eye care services across India, including establishing mobile eye care units.
- District Blindness Control Societies (DBCS) that operate at the district level to implement eye care initiatives, can organize screening camps and facilitate access to surgical treatments for corneal blindness.
- Training and Capacity Building: The Directorate General of Health Services (DGHS) and Regional Institutes of Ophthalmology (RIOs) can provide specialized training programs for eye surgeons and healthcare workers to enhance their skills in treating corneal conditions.
- Policy and Research Initiatives: The Ministry of Science and Technology can support research initiatives aimed at understanding the causes of corneal blindness and evaluating the effectiveness of interventions through funding and collaboration with research institutions.
- For example, the National Eye Bank Association of India can work on establishing guidelines for eye banks, promoting voluntary eye donations, and conducting research on best practices in eye banking
By implementing these strategies, India can make significant strides towards reducing the prevalence of corneal blindness and improving overall eye health across its population.
