To find out the correlation between myopic refractive error, corneal power and central corneal thickness (CCT) in the adult Egyptian population.
A retrospective observational cross-sectional study in which we analyzed the preoperative data of 1401 Egyptian myopic patients (1401 eyes) who underwent keratorefractive procedures between 2016 and 2019 in a private eye surgery center.
Mean age of patients was 28.1± 5.79 years (range 18-40). Mean CCT in the Egyptian population sample in our study was 539.23± 32.24. Only the corneal power parameters (flat K, steep K and average K) showed a statistically significant difference (p-value <0.001) between males and females. A statistically significant and weak positive correlation of average K with the absolute value of refractive astigmatism (r = 0.063, p-value = 0.018), and between myopic error with average K (r = 0.136, p-value <0.001) was found.
Among the myopic adult Egyptian population, the greater the myopic error measured, the steeper the cornea, with a weak positive correlation between refractive error and corneal power.
探究成年埃及人群中近视屈光不正、角膜屈光力与中央角膜厚度（CCT）之间的相关性。
一项回顾性观察性横断面研究，我们分析了2016年至2019年期间在一家私立眼科手术中心接受角膜屈光手术的1401例埃及近视患者（1401只眼）的术前数据。
患者的平均年龄为28.1±5.79岁（范围18 - 40岁）。我们研究中埃及人群样本的平均CCT为539.23±32.24。仅角膜屈光力参数（平K值、陡K值和平均K值）在男性和女性之间显示出统计学显著差异（p值<0.001）。发现平均K值与屈光性散光绝对值之间存在统计学显著且微弱的正相关（r = 0.063，p值 = 0.018），以及近视度数与平均K值之间存在正相关（r = 0.136，p值<0.001）。
在成年埃及近视人群中，测得的近视度数越高，角膜越陡，屈光不正与角膜屈光力之间存在微弱的正相关。
