    Abstract: Objective: This study intends to investigate the corneal biomechanical properties of persons with dry eye, keratoconus and normal eyes. Method: This study was a case-control study of the corneal biomechanical properties of patients with dry eye, keratoconus and normal eyes from The UWI Optometry Clinic. A total of 85 subjects and 3 study groups with 35 subjects making up the Healthy eyes control group, 30 subjects making up the Dry eyes group and 20 subjects making up the Keratoconus group. Results: The CH for dry eyes and normal eyes were determined to be 11.2 mmHg and 11.13 mmHg respectively. The CRF for dry eyes and normal eyes were determined to be 11.14 mmHg and 10.98 mmHg respectively. The CH and CRF for patients with keratoconus were determined to be 8.89 mmHg and 8.32 mmHg respectively. Conclusion: The findings indicate that there is a significant difference in the corneal biomechanical properties between keratoconic eyes and the healthy eyes group. However, there was no significant difference observed in the dry eyes group compared to the healthy eyes group. Consequently, it was concluded that the Ocular Response Analyzer machine can be employed as a diagnostic tool for keratoconus, but it would not be effective for diagnosing dry eyes.
