Corneal blindness is a major contributor of the blindness in the community. This study was done to know the frequency and etiopathogenesis of corneal blindness in tertiary health care centre. In our study, we included 75 eyes of 63 patients out of which 33 (52.4%) were males and 30 (47.6%) females. The age group included was from 4 to 83 years with mean age group of 43.67±22.89 years, 51 patients (80.9%) had unilateral corneal involvement and 12 patients (19.04%) had bilateral corneal involvement. The commonest cause of corneal blindness noted in our study was corneal opacity in 20 eyes (26.67%) along with infective and nutritional keratitis occurring in same percentage i.e 20 eyes (26.67%). Penetrating keratoplasty and its newer modifications are the mainstay treatment options for corneal opacity but it was done only in 10 eyes (50%). The biggest hurdle for reduced transplantation is lack of availability of good quality donor’s tissue along with suitable recipient. The procurement of healthy corneas is the necessity of time and so is the awareness about eye donation in the community.
