Abstractbackground: The assessment of corneal thickness has gained importance in different fields of ophthalmology in recent years, and measurement of the central corneal thickness (CCT) has become an important part of a routine examination in refractive surgery.
Aim: To determine the Correlation between Refractive Error and Central Corneal Thickness in A NAJAF Population with a Wide Range of Ametropia.
Method: In a cross sectional observational study, Involved 399 eyes of 200 Patients for whom the cen-tral corneal thickness (CCT) was measured with Ultrasonic pachymetry (TOMEY PACHYME-TER SP-3000).
The refractive error, including sphere, cylinder, and spherical equivalent (SE), were measured with Topcon (KR.8900) autorefractometer And Manual refraction.
Examination of anterior segment using slit lamp and fundoscopy using volk + 90 D, were done to exclude any underlying pathology
Results: The mean age of the study subjects was 30.71(range, 17 to 61) years. The mean spherical equiva-lent (SE) of the right eye was -3,2475 Diopter (range,-11.25 to 5.75 Diop-ters) while SE of the left eye was-3,2035 Diopter (range,-14.5 to 8.5 Diopters). The mean cen-tral corneal thick-ness(CCT) of the right eye 533,1600 Micron (range,407.00 to 635.00 Mi-cron) while CCT of the left eye was 532,7638 Micron (range,394.00 to 630.00 Micron). No significant correlation were found between spherical equivalent (SE) and central corneal thickness (CCT) of right and left eye among the studied group.
Conclusion: No significant Relation found between Refractive errors and central corneal thickness (CCT).
