Background: A corneal foreign body is one of the main causes of blindness factor. The effects can be mild infections (corneal abration, keratitis) to severe (endophthalmitis) depending on the type of material. Late-stage complications can cause blindness. Objective: This study to determine the effect of types of corneal foreign body material on the severity of eye infection. Method: Non-experimental research with analytic observational method and cross-sectional study. Subject was 30 patients. The sample was male and female patients (10 - 70 years old) who came to the eye clinic with a history of exposure to corneal foreign bodies of less than 8 days. The study was conducted by interviews and visual examination on anterior segment of the eyes. The statistical analysis by Statistical Package for the Social Sciences (Simple Linear Regression and Spearman). Results: There are several types of foreign body material that affect cornea; gram iron (53.3%), plant branches (16.7%), animal wings (13.3%), sand (13.3%) and food (3,4 %). Most of these types of material cause corneal erosion (66.7%) and keratitis infections (33.3%). The incidence of corneal ulcers, endophthalmitis and panophthalmitis was not present in this study. Conclusion: There were no significant differences between the types of corneal foreign body material and the severity of eye infections.
