Purpose: To examine if central corneal thickness (CCT) is different in emmetropia and high myopia. Methods: 57 emmetropic subjects (0 to+ 1.5 D) and 48 high myopes (all more than- 6 D in spherical equivalent refraction) were studied. CCT was measured by a Haag-Streit Optical Low-Coherence Reflectometry (OLCR) pachymeter, a recently developed high precision pachymeter with a standard deviation (SD) for repeated measurements of 1 μ m. Results: Mean CCT for the emmetropic group was 538.6 μ m (SD=32.1), and for the myopic group 527.7 μ m(SD=35.0). Neither the mean CCT nor the variance from the two groups showed a statistically significant different (p >0.05). Conclusion: CCT is not systematically altered in myopia. The process by which the myopia progresses does not to a measurable degree influence the central cornea.
