目的 :准分子激光原位角膜磨镶术 (excimerlaserinsitukeratomileusis ,LASIK)治疗近视是目前屈光手术中备受关注的方法之一 ,它的安全性 ,稳定性都较好。但是对于屈光回退的讨论及可能影响的因素 ,还需不断进行研究。本文对经LASIK手术治疗的 12 80例患者 ,2 316只眼进行分析。方法 :分为两组进行比较 ,一组为中低度近视 (- 1 0 0D～ - 6 0 0D) ,二组为高度近视 (>- 6 0 0D)。结果 :中低度近视回退率为 1 2 9% ,高度近视回退率为 6 32 %。高年龄组回退率较低年龄组高 (P <0 0 1)。近视的回退量与年龄及术后角膜基质床厚度成负相关性 ,与术前的近视度数成正相关性。结论 :LASIK术后回退与年龄、术前屈光度数、术后角膜基质床的厚度、角膜上皮的增厚程度等因素有关
OBJECTIVE: Excimer laser in situ keratomileusis (LASIK) for the treatment of myopia is one of the most popular methods in refractive surgery. Its safety and stability are good. However, the discussion of refractive regression and the possible factors that affect the need for continuous research. This article analyzes 12 80 patients treated with LASIK surgery and 2 316 eyes. Methods: The patients were divided into two groups: one was moderate and low myopia (-100D ~ -600D), the other two were high myopia (> -600D). Results: The regression rate of low myopia was 122.9%, and the regression rate of high myopia was 6 32%. High age group regression rate lower age group (P <0.01). The amount of regression of myopia was negatively correlated with age and postoperative thickness of corneal stroma, which was positively correlated with preoperative myopia. Conclusion: The regression after LASIK is related to the age, preoperative refractive power, postoperative corneal stromal bed thickness, corneal epithelial thickening and other factors
