The most prevalent risk factors include trauma, contact lens use, and the use of steroid prescription drugs.

At Kolkata's Regional Institute of Ophthalmology's  weekly cornea clinic, 150–180 patients line up to get examined each week.

Eye pain, which can range in intensity from mild to severe, is one of several symptoms of corneal blindness. Other typical symptoms include light sensitivity, hazy vision, ocular discharge, watery eyes, etc.

Meena Devi, a domestic help who hails from West Bengal's 24 parganas (South) district, faced issues with her vision for two months before she sought help from doctors.

Md Jahangir, a rickshaw puller, too struggled with symptoms for three months. Now, he is battling blindness brought on by an infection in the cornea. For someone like Jahangir, who is the primary breadwinner of his family, the effects of this has been catastrophic economically.

Parul Mandal, who hails from the South 24 district and was visiting an eye doctor for the first time, sobbed at the clinic. As a side effect of the drug used to treat her chicken pox, she had been experiencing symptoms of corneal blindness and could hardly stand the light.

Dr Chatterjee confessed that in the condition that she was in, "even an operation might not help her eyesight."

For a 14-year-old (who did not want to be named), a herpes simplex virus in her eye damaged her cornea. Clinically known as Herpes Keratitis, this is a condition that affects the clear layer that covers the front of the eye (cornea).

Dr Ashis Majumdar and Dr Asmita Gope, examining an infant, tell FIT, "A newborn's cornea can become clouded due to bacterial or viral illnesses (such as rubella or herpes simplex)."

A Schirmer test is being performed on a patient to gauge tears. One of the main corneal-related causes of blindness is a dry eye illness.

Although a wide variety of medications are required to treat corneal problems, the most frequently prescribed medications are natamycin, tobramycin, and moxifloxacin.

Dr Majumdar says, "There are several cases where I have come across a patient's eyes that can be saved if the family members brought them here on time. Many patients stop visiting us or stop their medications just after one or two visits. Corneal Illness can be treated, but it also needs continuous care. It's a long-term process. A damaged eye can't be saved overnight."

Binay Pal of Hooghly district, who has completely healed from corneal disease and regained his vision, came to the clinic for a final check-up. Opening a popular Bengal daily to its television page, Pal told FIT, "I'm happy that I can start watching Bengali soap operas."

In India, an estimated 1.3 million people suffer from corneal blindness, the National Programme for Control of Blindness had stated in 2022.

Even as the burden of the disease is increasing, awareness about it hasn't kept up. Corneal blindness is more common than we'd like to think.

At Kolkata's Regional Institute of Ophthalmology's weekly cornea clinic, 150–180 patients line up to get examined each week. FIT visited the clinic last week.
