LASIK,SMILE和PRK的优势及适应证（英文）

LASIK,SMILE and PRK: advantages and indications

屈光性角膜切削术(PRK),激光原位角膜磨镶术(LASIK)和小切口微透镜取出术(SMILE)是目前临床上屈光性手术中有效和安全的方法。这三种激光视力矫正方法虽然技术不同,但成功率大致相同。至于哪种方法是最合适的取决于多种因素,包括:屈光度、个人习惯和职业因素(如运动和生活方式)。目前,LASIK屈光手术应用最广,但SMILE也在手术医生间快速推广。后者提高了术后早期的舒适感,还有视力的快速恢复,减少了伤口的愈合反应。此外,与LASIK相比,SMILE术后干眼的发生率较低,因为小切口使前基质损伤小,这意味着前部角膜神经受到影响小。与LASIK和PRK相比,SMILE同样可以降低高阶像差(HOA)的形成。术后角膜滞后量(CH)和角膜阻力因子(CRF)与SMILE、LASIK、PRK方法无明显差异。但是,PRK仍然是中度到轻度手术量的最佳选择,特别是涉及薄角膜、频繁角膜侵蚀的病例。

Photorefractive keratectomy(PRK),laser-assisted in situ keratomileusis(LASIK)and small-incision lenticule extraction(SMILE)are the most clinically effective and safe techniques,for refractive surgery.All three kinds of laser vision correction,while varying in technique,have roughly a similar high achievement rate.Which method is best for you to rely upon various components like the refractive error,habits and profession,for example,sports and lifestyle.LASIK is as of now the predominant strategy in refractive surgery but SMILE also spreads rapidly between surgeons.This increments comfort amid the early postoperative period,takes into account quick visual recovery,and diminishes the wound healing response.And additionally that there would be less postoperative dry eye after SMILE contrasted with LASIK because the anterior stroma is exasperates just by the small incision,implying that the anterior corneal nerves ought to be less influenced.SMILE likewise lower induction of higher order aberrations(HOA)contrasted with LASIK and PRK.No contrasts between SMILE,LASIK and PRK medicines in postoperative corneal hysteresis(CH)corneal resistance factor(CRF)or corneal hysteresis values.PRK,but,remains a supreme option for moderate to mild modifications,especially for cases involving thin corneas,frequent erosions.
