c. Dangerous.
d. Serious.
1. Grievous.
The Essentials of Forensic Medicine and Toxicology 21st Edition : K.S.Narayana Reddy Page 224
Indian Penal Code - Chapter XIV Relevant Sections 319 to 338 - Given in all text books
319. Hurt
Whoever causes bodily pain, disease or infirmity to any person is said to cause hurt.
320. Grievous hurt
The following kinds of hurt only are designated as "grievous":-
First- Emasculation.
Secondly- Permanent privation of the sight of either eye.
Thirdly- Permanent privation of the hearing of either ear,
Fourthly- Privation of any member or joint.
Fifthly- Destruction or permanent impairing of the powers of any member or joint.
Sixthly- Permanent disfiguration of the head or face.
Seventhly- Fracture or dislocation of a bone or tooth.
Eighthly- Any hurt which endangers life or which causes the sufferer to be during the space of twenty days in severe bodily pain, or unable to follow his ordinary pursuits.
There is a lot of discussion as to the nature of the Injury. Few say that since the loss is not PERMANENT it is simple Injury. That may sound logical, but when we see the clause eight, which says that any hurt which causes the sufferer unable to follow his ordinary pursuit for 20 days is Grievous. It is rational to assume that a person who had injury in Right Eye and had undergone Corneoplasty would not have used his eyes for at least 20 days. So the injury becomes grievous.
There is another interesting explanation to this question. Cornea is a part of face (Isn’t it?) and Corneoplasty implies that there is Permanent disfigurement of face à which means that the injury undoubtedly is grievous.
