At least 11 elderly people have lost their eyesight in Chhattisgarh after they were operated upon for cataract at a much publicised government health camp, officials said Thursday. A probe has been ordered into the incident.

"Eleven people who went for minor cataract surgeries at a government health camp late last month at Balod in Durg district have lost their eyesight days after the operation. They were admitted Thursday to Raipur's Dr. Bhimrao Ambedkar Government Medical College and Hospital," an official at the Directorate of Health Services here told IANS.
