SMILE术后增效手术的研究进展

Research Progress on Retreatment after SMILE

飞秒激光小切口角膜基质透镜取出术(SMILE)是目前主流的角膜屈光手术之一,尽管手术成功率高,但术后仍会出现过矫、欠矫和屈光回退等问题,影响术后视力。随着SMILE的日益普及,一些患者不可避免地需要进行增效手术。现笔者就SMILE术后增效手术的种类、优缺点及研究进展等方面展开综述。

Small incision lenticule extraction(SMILE)is one of the mainstream corneal refractive surgery at present.Although the success rate of the surgery is high,there are still some postoperative residual refractive errors such as overcorrection,undercorrection and refractive regression,which affect postoperative vision.With the increasing popularity of SMILE,some patients inevitably need to perform retreatment surgery.This review discusses major advantages and disadvantages of these options and compares the visual outcomes based on the existing literature.
