准分子激光原位角膜磨镶术后9年行SMILE补矫1例

A case report of SMILE for refractive regression nine years after myopia correction with laser in situ keratomileusis

1例9年前因近视眼行“双眼准分子激光角膜切削术”男性患者因屈光不正(近视眼)行飞秒激光小切口角膜基质透镜取出术(SMILE)。术中切削角膜帽时出现气泡散逸,明确既往手术方式为准分子激光原位角膜磨镶术(LASIK),右眼继续完成SMILE,左眼改为原位掀角膜瓣LASIK。术后随访双眼裸眼视力均达到术前最佳矫正视力。希望本病例为临床开展角膜屈光手术二次补矫手术提供经验和借鉴。

A myopic patient with self‑reported photorefractive keratectomy 9 years ago requested small incision lenticule extraction(SMILE)as retreatment.The presence of interface bubbles while creating a corneal cap of the right eye revealed that the previous refractive surgery was laser in situ keratomileusis(LASIK).Therefore,the SMILE procedure was resumed in the right eye,but flap‑lift LASIK was performed in the left eye.Postoperative follow‑up showed that the vision in both eyes reached the preoperative best corrected level.SMILE may be a potential option for refractive regression after LASIK.
