目的：探究术前应用人工泪液联合重组牛碱性成纤维细胞生长因子(rbFGF)对白内障合并干眼患者术后眼表功能和泪液中炎症因子水平的影响。

方法：选取2019-02/2020-02我院收治的白内障合并干眼患者118例118眼作为研究对象，随机分为对照组和观察组，各59例59眼，对照组术前采用人工泪液治疗，观察组术前采用人工泪液联合rbFGF治疗。比较两组患者治疗前后临床症状评分、眼表功能指标\〖眼表疾病指数(OSDI)问卷评分、泪膜破裂时间(BUT)、基础泪液分泌试验(SⅠt)和角膜荧光染色评分(FL)\〗、泪液中炎症因子\〖白细胞介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)\〗及氧化应激指标\〖丙二醛(MDA)、脂质过氧化物(LPO)、超氧化物歧化酶(SOD)、总抗氧化能力(TAC)\〗水平，并采用随机行走模型评价两组患者眼表功能及泪液中炎症因子水平。

结果：治疗前，两组患者临床症状评分、OSDI、BUT、SⅠt、FL、IL-6、TNF-α、MDA、SOD、LPO、TAC水平均无差异(P>0.05)； 治疗后30d，两组患者临床症状评分、OSDI、FL、TNF-α、IL-6、MDA、LPO水平明显降低，BUT、SⅠt、SOD、TAC水平明显增加，且观察组患者治疗后的临床症状评分、眼表功能、炎症因子及氧化应激指标改善情况明显优于对照组(P<0.05)。

结论：术前采用人工泪液联合rbFGF进行干预可明显改善白内障合并干眼患者术后眼表功能，降低泪液中炎症因子水平，改善干眼症状，为临床上白内障合并干眼的治疗提供参考。

METHODS: A total of 118 cataract patients(118 eyes)with dry eyes treated in our hospital from February 2019 to February 2020 were randomly divided into control group(n=59)and observation group(n=59). The control group was treated with artificial tears before operation and the observation group was treated with artificial tears combined with rbFGF before operation. The clinical symptom score, ocular surface function index \〖ocular surface disease index(OSDI)questionnaire score, break up time(BUT), schirmer Ⅰ test(SⅠt), fluorescein stain test(FL)\〗, inflammatory factors in tears \〖interleukin-6(IL-6), tumor necrosis factor α(TNF-α)\〗 and oxidative stress indexes \〖malondialdehyde(MDA), lipid peroxide(LPO), superoxide dismutase(SOD), total antioxidant capacity(TAC)\〗 were compared between the two groups before and after treatment. The random walking model was used to evaluate the ocular surface function and the level of inflammatory factors in tears of the two groups.

RESULTS: Before treatment, there was no significant difference in clinical symptom score, OSDI, BUT, SⅠt, FL, IL-6, TNF-α, MDA, SOD, LPO and TAC between the two groups. Thirty days after treatment, the clinical symptom score, OSDI, FL, TNF-α, IL-6, MDA and LPO levels in two groups were significantly decreased, while the levels of BUT, SⅠt, SOD and TAC were significantly increased. The improvement of clinical symptom score, ocular surface function, inflammatory factors and oxidative stress in the observation group were significantly better than that in the control group.

CONCLUSION: Preoperative intervention with artificial tears combined with rbFGF can significantly improve the ocular surface function of cataract patients with xerophthalmia, reduce the level of inflammatory factors in tears, improve the symptoms of xerophthalmia, and provide reference for the clinical treatment of cataract with xerophthalmia.
