【摘要】：目的比较白内障角膜颞侧切口和角膜上方切口对术后泪膜和眼表的影响。方法将接受白内障超声乳化手术的55例患者(66只眼)随机分入角膜颞侧切口组(颞侧组)和角膜上方切口组(上方组),比较两组患者间术前、术后1周和1个月的视力、眼压、泪膜破裂时间(TFBUT)、泪液分泌功能试验(Schirmer试验)结果、泪河高度、角膜荧光染色和角膜内皮细胞计数,并评估两组患者泪膜稳定性和眼表情况。结果颞侧组患者术前和术后1个月的眼压分别为(16.17±0.49)和(14.44±0.51)mmHg(1mmHg=0.133kPa),分别显著高于上方组同时间的(14.25±0.60)和(12.75±0.57)mmHg(P值均0.05)。颞侧组患者术前、术后1周和术后1个月的视力、TFBUT、Schirmer试验结果、泪河高度、角膜染色分级和角膜内皮细胞计数与上方组同时间比较,差异均无统计学意义(P值均0.05)。结论白内障超声乳化手术中,角膜颞侧切口和角膜上方切口对患者的泪膜稳定性和眼表情况均无明显的影响。
[Abstract]:Objective to compare the effects of temporal incision and superior incision on tear film and ocular surface after cataract surgery. Methods Fifty-five patients (66 eyes) undergoing phacoemulsification were randomly divided into temporal incision group (temporal group) and superior corneal incision group (upper group). The visual acuity and intraocular pressure (IOP) were compared between the two groups before, 1 week and 1 month after operation. The results of (TFBUT), tear secretion function test (Schirmer test), the height of lacrimal river, corneal fluorescence staining and corneal endothelial cell count were used to evaluate the tear film stability and ocular surface of the two groups. Results Intraocular pressure (IOP) in the temporal group was (16.17 卤0.49) and (14.44 卤0.51) mmHg (1mmHg=0.133kPa), respectively, which was significantly higher than that in the upper group (14.25 卤0.60) and (12.75 卤0.57) mmHg (P, respectively. The visual acuity of temporal side group before operation, 1 week after operation and 1 month after operation showed no significant difference (P < 0.05). The height of lacrimal river, corneal staining grade and corneal endothelial cell count were not significantly different from those of the above group (P < 0.05). Conclusion in phacoemulsification of cataract, there is no significant effect on the stability of tear film and ocular surface in patients with phacoemulsification.
