Aim and objectives: This study tries to estimate the relationship between biomicroscopic features and topographic features of keratoconus. 
Design: Descriptive cross sectional study. 
Materials and Methods: Symptomatic keratoconic patients between the age group of 10-30 years were included in this study. Biomicroscopic examination, retinoscopy and corneal topography were done for the patients and their correlation studied. 
Results: The study group included 92 keratoconic eyes having defective vision. The mean age of patients with keratoconus was 20.08 years (SD ± 4.5), 59% (n=54) were males. This study showed a statistically significant positive correlation between anterior segment findings and corneal topographic features. 
Conclusion: Along with biomicroscopic examination, corneal topographic examination is an important method for diagnosis of keratoconus.
