 Purpose: To find the correlation of Central Corneal Thickness(CCT) to degree of myopia and compare it with emmetropes.  Method: Prospective study, the CCT of 50 myopic eyes from myopic patients and 50 emmetropic eyes from control group was measured using ultrasound pachymetry at Ophthalmology department, Saveetha Hospital.  Result: The mean myopic spherical equivalent was -2.5D, range -0.75D to -4.25D. the mean CCT of emmetropic group was 577.2 micrometer and the mean CCT of myopic group was 558.54micrometer. The mean CCT between myopic and emmetropic group was statistically significant. There was correlation between CCT and degree of myopic spherical equivalent .  Conclusion: This study showed that there was some difference in CCT between emmetropes and myopic eyes (P=0.0011). As myopic degree increases central corneal thickness decreases. (On correlation, value is -0.2039)
