Small-incision lenticule extraction (SMILE) was performed in a patient with high astigmatism and nystagmus. The patient presented for a refractive surgery evaluation with a manifest refraction of -0.50 -6.00 × 137 (20/40) in the right eye and -2.25 -2.25 × 30 (20/40) in the left eye. The patient was deemed suitable for corneal laser refractive surgery. Consideration was given to SMILE, laser in situ keratomileusis, and photorefractive keratectomy. It was decided SMILE was the best option given that the refractive portion of the procedure is performed while the cornea is immobilized by suction. The treatment was uneventful, and the final manifest refraction was +0.25 -0.25 × 130 (20/40) in the right eye and +0.25 diopter sphere (20/40) in the left eye. Topography was normal, showing a well-centered treatment zone. This case highlights an additional use for SMILE, given its ability to immobilize the cornea during treatment.
小切口微透镜切除术（SMILE）应用于一位高度散光伴眼球震颤患者。该患者因屈光不正就诊，右眼矫正视力为 -0.50 -6.00×137（20/40），左眼为 -2.25 -2.25×30（20/40）。患者适合行角膜激光屈光手术。考虑行 SMILE、激光原位角膜磨镶术和光性折射性角膜切削术。由于在角膜吸力固定下进行手术的折射部分，因此决定 SMILE 为最佳选择。手术过程顺利，最终的矫正视力右眼为+0.25 -0.25×130（20/40），左眼为+0.25 屈光度球镜（20/40）。地形图正常，显示治疗区中心位置良好。该病例突出了 SMILE 的另一种用途，因其能够在治疗过程中固定角膜。
