Aim and Objectives: This study tries to estimate the relationship between corneal topographic patterns and topographic parameters with the clinical findings among keratoconus cases. Design: This was a descriptive cross-sectional study. Materials and Methods: 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 with topographic pattern was studied. Results: The study group included 89 keratoconic eyes having defective vision. The mean age of patients with keratoconus was 20.13 years (standard deviation ± 4.56). This study showed a statistically significant positive correlation between a few topographic pattern and inferior–superior values. Conclusion: Varied topographic patterns are seen among keratoconus cases diagnosed based on an elevated KISA index. Atypical patterns may be indicative of other causes of corneal ectasia. A comprehensive evaluation of clinical findings, topographic patterns, and keratometric values is essential in the diagnosis and follow-up of keratoconic eyes.
