HYDERABAD: Seven patients at a government hospital lost vision in one eye after botched-up surgeries. Conducted at Sarojini Devi Eye Hospital, the series of mishaps cost four women and three men, all aged between 50 to 70, their eye sight. After an inquiry, it was found that the patients had developed a bacterial infection caused by superbug Klebsiella, which was found in the saline solution given to them during the process. "The doctors concerned are nowhere to be seen now to tell me just when I will regain vision in my left eye," said S Anji Reddy. Patients began to experience unbearable pain and puss formation in their eyes soon after the procedure. A case under Section 338 of the IPC has been registered against the hospital.
