Aim: To assess the correlation of central corneal thickness (CCT) with the degree of myopia. Methods: This is a prospective observational study. A total 280 patients were enrolled in a refractive surgery clinic. Total ophthalmic assessment including refraction was performed. CCT was determined in each eye of the all patients using ultrasonic pachymeter. Five different reading were taken during morning time and average of it was considered. The correlation of CCT and the degree of myopia in dioptres (D) was identified by Pearson’s correlation coefficient and multiple comparisons Dunnett’s t test. Results: Mean age of patients 24.85 ± 1.41 in males and 24.61 ± 7.77 in females. Mean value of myopia was -5.70 ± 2.12 D and -5.87 ± 3.18 D in males and females respectively. Mean corneal thickness was 539.19 ± 42.42 μM in males while it was 531.46 ± 12.02 μM in females. The correlation between CCT and the degree of myopic spherical equivalent was statistically insignificant (r=20.13, p=0.72). The insignificant (p > 0.05) association was found between the CCT and myopia groups while CCT was divided in to two groups. Conclusion: There is no significant difference noted among myopic refractory error and CCT. There was no significant difference between CCT, which remains nearly same in all degree of myopic eyes. This is clinically irrelevant and it does not affect the management of patients.
