Shanti Bala Das was admitted to the College of Medicine & JNM Hospital at Kalyani to remove cataract from her left eye, but she was operated on her right eye, her son-in-law Narayan Biswas complained to police and hospital authorities.
The surgeon concerned Mahua Mukherjee and hospital Principal Shantanu Banerjee, however, said, "Both her eyes had been affected and it was made clear to the patient party."
"There was no mistake on part of the surgeon," Banerjee said.
Biswas said her mother-in-law was released after the operation but her right eye started to bleed after reaching home.
He claimed the surgeon had admitted her mistake and requested them not to lodge any complaint.
