Vaishnavi's dad, San, had high hopes for his little girl and wanted to see her to do well in school. All that was threatened when he noticed that the five-year-old wasn't playing as much as she used to and kept falling over, telling him she couldn't see.
After seeing something had developed in Vaishnavi's eye, San took her to the doctor in their village in the state of Bihar, in India. The doctor explained that she had a cataract and that with time it would only get worse. Commonly, most cases of cataracts occur in older people, but the eye condition can appear at any age - even in childhood.
San was very worried and knew he needed to get treatment for his little girl quickly.
The longer a child like Vaishnavi waits for eye surgery, the more likely they will suffer irreversible damage and become blind for life.
