To report a case of interface fluid syndrome (IFS) following small incision lenticule extraction (SMILE) evaluated with corneal densitometry and optical coherence tomography (OCT).
An 18-year-old man reported sudden vision loss 24 days after SMILE procedure. Intraocular pressure (IOP) was 36.3 mmHg (OD) and 36.7 mmHg (OS) by noncontact tonometry. Moderate corneal edema, interface fluid pocket and haze were observed by OCT and confirmed by corneal densitometry values. Discontinuation of steroids and addition of hypotensive medication were offered immediately. The symptoms were cured after the medication. Changes of corneal densitometry were consistent with the clinical course of IFS.
This case illustrates that it is crucial to be aware that a history of SMILE can also cause IFS. Both OCT and corneal densitometry can serve as auxiliary means to evaluate the clinical course of IFS, and appropriate IOP management is an effective approach.
报告一例小切口透镜切除术（SMILE）后发生界面液体积聚综合征（IFS）的病例，并通过角膜密度测定和光学相干断层扫描（OCT）进行评估。
一名18岁男性在SMILE手术后24天突然视力丧失。非接触眼压计测量的眼压为右眼36.3 mmHg，左眼36.7 mmHg。OCT观察到中度角膜水肿、界面液体积聚和混浊，角膜密度测定值证实了这一情况。立即停用类固醇并加用降压药物。用药后症状治愈。角膜密度测定的变化与IFS的临床病程一致。
该病例表明，认识到SMILE病史也可导致IFS至关重要。OCT和角膜密度测定均可作为评估IFS临床病程的辅助手段，适当的眼压管理是一种有效的方法。
