| 目的分析并比较轻度干眼与非干眼病人行飞秒激光小切口角膜基质透镜取出术( SMILE)后弥漫性层间角膜炎(DLK)的发生率，探讨干眼与 SMILE术后 DLK的发生是否有相关性，为 SMILE手术的适应证提供依据。方法连续性纳入 2021年 12月至 2023年 2月在贵州医科大学附属医院眼科接受 SMILE手术者 627例( 627只眼)均选择右眼，根据术前干眼检查结果，将确诊为干眼且裂隙灯显微镜下观察到角膜荧光素染色点小于 5个或不超过 1个象限，，泪膜破裂时间大于 2s的病人纳入轻度干眼组( 316只眼)将角膜荧光素染色阴性且泪膜破裂时间大于 10 s的病人纳入非干眼组( 311只眼)。比较两组病人 SMILE术后 1d、1周、 1个月，DLK的发病率及临床分期，并分析术前一般资料及干眼相关检查指标与 DLK的相关性。结果轻度干眼组 SMILE术后共有 34只眼发生了 DLK，发生率为 10.76%；非干眼组 SMILE术后共有 15只眼发生了 DLK，发生率为 4.82%。两组术后 DLK发病率差异有统计学意义( P<0.05)。术前一般资料及干眼检查的相关指标中，眼压、睑板腺形态、泪膜脂质层厚度、泪液分泌试验 Ⅰ、角膜荧光素染色 5个变量差异有统计学意义( P<0.05)其中，术前眼压、睑板腺形态及角膜荧光素染色为危险因素，泪膜脂质层厚度、泪液分泌试验 Ⅰ为保护因素。结论轻度干眼病，人行 SMILE术后 DLK发生率高于非干眼人，干眼及眼压可能是 SMILE术后发生 DLK的一种危险因素，故术前有轻度干眼及眼压偏高的病人应积极处理后再行 SMILE手术，避免术后 DLK的发生。 |

| Objective To analyze the incidence of diffuse lamellar keratitis (DLK) after femtosecond laser small incision lenticule ex-traction (SMILE) in patients with mild dry eye and non-dry eye, and to investigate whether there is a correlation between dry eye andDLK after SMILE surgery, in order to provide a basis for the indications of SMILE surgery.Methods A total of 627 patients (627 eyes)who underwent SMILE surgery in the Department of Ophthalmology at Guizhou Medical University Affiliated Hospital between Decem-ber 2021 and February 2023 were consecutively enrolled, all of whom selected the right eye. According to the results of preoperativedry eye tests, patients diagnosed with dry eye and observed under a slit lamp with less than 5 corneal fluorescein staining spots or nomore than one quadrant, and a tear breakup time greater than 2 seconds, were included in the mild dry eye group (316 eyes), patientswith negative corneal fluorescein staining and a tear film rupture time greater than 10 seconds were included in the non-dry eye group(311 eyes). The incidence and clinical stage of 1d, 1w and 1m DLK after SMILE were compared between the two groups, and the corre-lation between preoperative general information and dry eye-related examination indicators and DLK were analyzed.Results In the mild dry eye group, 34 eyes (10.76%) developed DLK after SMILE surgery; in the non-dry eye group, 15 eyes (4.82%) developed DLKafter SMILE surgery. The difference in the incidence of DLK after surgery between the two groups was statistically significant (P<0.05). The differences of five variables showed statistical significance (P<0.05) among the preoperative general information and dry eye-relat-ed examination indicators: intraocular pressure, meibomian gland morphology, tear film lipid layer thickness, tear secretion test Ⅰ, andcorneal fluorescein staining. Among them, preoperative intraocular pressure, meibomian gland morphology, and corneal fluorescein staining were risk factors, while tear film lipid layer thickness and tear secretion test Ⅰ were protective factors.Conclusions The inci-dence of DLK in mild dry eye patients after SMILL is higher than that in non-dry eye patients. Dry eye and intraocular pressure may berisk factors for DLK after SMILE surgery, therefore, patients with mild dry eye and elevated intraocular pressure should be treated ac-tively before undergoing SMILE surgery to avoid the occurrence of DLK after surgery. |
