Small incision lenticule extraction (SMILE) is a minimally invasive, safe and flapless femtosecond laser technique used mainly to correct myopia through extraction of a corneal lenticule. Lenticules obtained in this way are transparent and of high quality, and thus, can be used to treat other corneal diseases. A 65-year-old male patient presented with recurrent pterygium complicated by thin cornea. The patient was treated surgically using a SMILE-extracted lenticule to avoid further complications and to maintain eyeball integrity. The lenticule was sutured over the thin section of cornea using 10-0 interrupted nylon sutures and enclosed by a single layer of amniotic membrane. The patient was evaluated using slit-lamp biomicroscopy and anterior-segment optical-coherence tomography. During an 8-month follow-up, the graft remained intact with no sign of rejection and corneal thickness was maintained. Tectonic keratoplasty using a SMILE-extracted lenticule appears to be a safe, cost-effective and reliable method for treating thin cornea due to repeated surgeries for recurrent pterygium. This is the first case of recurrent pterygium complicated by thin cornea managed surgically using a SMILE-extracted lenticule.
小切口飞秒透镜切除术（SMILE）是一种微创、安全且无瓣的飞秒激光技术，主要用于通过切除角膜透镜来矫正近视。以这种方式获得的透镜是透明且高质量的，因此可用于治疗其他角膜疾病。一名65岁男性患者患有复发性翼状胬肉并伴有角膜变薄。对该患者采用SMILE切除的透镜进行手术治疗，以避免进一步的并发症并维持眼球完整性。使用10-0间断尼龙缝线将透镜缝合在角膜薄区上方，并用单层羊膜覆盖。使用裂隙灯生物显微镜检查和眼前节光学相干断层扫描对患者进行评估。在8个月的随访期间，移植片保持完整，无排斥迹象，角膜厚度得以维持。对于因复发性翼状胬肉反复手术导致的角膜变薄，使用SMILE切除的透镜进行的结构性角膜移植术似乎是一种安全、经济有效且可靠的治疗方法。这是首例使用SMILE切除的透镜对复发性翼状胬肉合并角膜变薄进行手术治疗的病例。
