²Çukurova Üniversitesi, Medikososyal Merkezi, Adana Purpose: To compare the central corneal thicknesses (CCT) of patients having different refractive errors, and to determine the correlation between the CCT and the type and degree of refractive error.
Materials and Methods: The mean CCT of 64 myopic and 64 hyperopic patients, having astigmatism <1.0 Diopter (D), was calculated. In the half of the myopic group (32 eyes), the spherical equivalant was >-3.0 D, while in the other half (32 eyes) it was <-3.0 D. Similarly, hyperopic eyes were grouped in two halves as one (32 eyes) having spherical equivalant >+3.0 D, and the other half (32 eyes) <+3.0 D. The CCT of 32 emmetropic eyes were evaluated as the control group. The CCT were compared between myopia, hyperopia and emmetropia groups. And also the correlation between CCT and spherical equivalant diopter, and the relationship between CCT and age are investigated.
Results: The mean CCT of myopia and hyperopia group were found 544±36 μm and 548±46 μm respectively. The difference between the CCT of myopic and hyperopic eyes was not significant. The mean CCT of emmetropic eyes in control group was found 551±28 μm. The difference between the CCT of control group and the eyes with refractive error was not significant. The mean CCT of myopia and hyperopia groups having spherical equivalant upper and lower than 3.0 D showed no significant difference.
Conclusion: Central corneal thickness is not releated with type and degree of refractive error. Keywords : Central corneal thickness, refractive error
