"I used to keep the books too close to my eyes to read," 19-year-old Ashish Choudhary, son of a farmer and hailing from Khandwa in Madhya Pradesh told reporters here today.
A student of B.Tech, he could not comfortably read, write or see the blackboard due to the compromised vision.
Despite a surgery at his native place, the vision did not improve much, he added and thanked his professors at IIT who came forward to support him financially for the surgery.
"Micro cornea (8 mm in diameter) and tilted lens (both eyes) led to impaired vision and he was partially blind," Dr Amar Agarwal of Dr Agarwal's Eye Hospital said.

"We fixed intra-ocular lens into his eyes using biological glue," he said adding "the student now has normal vision."
He claimed that the bio-glue was used for the first time in a surgery for a patient with micro cornea though the IOL implantation or glued IOL technique is in use.
Normally, the cost of the surgery is about Rs one lakh but it was done for Rs 50,000 for the student.
