ترجمة الملخص

Axial length measurement is important part of IOL power calculation and small error in the measurement leads to major mistakes in calculation according to SRK formulaP = A -(2.5L) -0.9KP=power A=constant related to iolL= axial lengthK=keratometryThe goal of research: Comparative Study for the difference in the Axial length measurement between QuantelMedical Cinescan(QMC) device and TomeyAL 100 device to determine accurate one .Patients and methods: We undertook this study in the Department of eye diseases in Al-mouassatUniversity Hospital of Damascus in the period between 1 FEB 2013 and 1 FEB 2014, and all patients were followed up for at least 3 months after surgery. The study included 30 eye for 25 patients with compliant of age related cataract, where we take the full story with full eye examination and measure of keratometryand Axial length using both QMC and TomeyAL 100 devices and then we divide the patients into two groups: 15 eyes in the first group, in which we calculate IOL power according QMC measurements15 eyes in the second group, in which we calculate IOL power according Tomey AL 100 measurements We follow up patients and measure refractive error ,uncorrected visual acuity and corrected visual acuity after week –month -3 months of surgery Results:The mean age was 61.2 ±8.8 years in the first group and, 60.6 ±9.4 years in the second group. The mean of difference of Axial length is 0. 13667 and it is statically important p=0 . After 3 months of follow up , there is significant difference between preoperative predicted refractive error and measured postoperative refractive error in TomeyAL 100 group (p=0.032) ,whereas there is not any difference in QMC group (p=0.295) .And The postoperative uncorrected visual acuity in both groups are significantly difference (p=0) whereas there was no significant difference preoperative (p=0.63)Conclusion:We find significant difference in axial length and predicted IOL power measurements between QMC and Tomey AL 100 ,besides QMC is more accurate . after we subside other causes of error like calibration ,settings ,examiner ,special cases ,we find that the causeofthis results probably due to difference in the shape of probe which is like (T) in QMC and like pen in Tomey AL 100 . So the examiner in QMC can catch the wire instead of the probe with minimal pressure on cornea ,whereas he/she have to catch the probe which may lead to more pressure on cornea .
