Inclusion criteria were patients diagnosed with fungal keratitis based on microbiological findings, corneal infiltration area should be < 10mm in diameter, history of vegetative  trauma, satellite lesions on the cornea, corneal stoma and irrespective of age and gender. Exclusion criteria were other types of keratitis, perforation in the cornea, any stage of endophthalmitis, mature cataract,ocular diseases in combination, involvement of sclera, corneal transplantation and fungal infection overspreading stroma and anterior chamber.


Results: A total of 76 participants were included in this study. The mean age was 53.25±10.56 with range of 30-70 years. Mean duration of vegetative trauma at time of presentation was 10.05±4.34 days. There were 27 (35.53%) male and 49 (64.47%) female. There were 54 (71.05%) patients from rural side.Visual acuity status at the last follow-up of the third month showed improvement in visual acuity was seen in 63 (82.89%) respondents, vision remained stable in 11 (14.47%) however 2 (2.63%) had worsened their vision after intervention.
