2.6mm与3.0mm透明角膜隧道式主切口超声乳化白内障吸除术治疗老年性白内障患者的效果比较

Comparison of effects of 2.6 mm and 3.0 mm clear cornea tunnel main incision phacoemulsification in treatment of senile patients with cataract

目的:比较2.6 mm与3.0 mm透明角膜隧道式主切口超声乳化白内障吸除术治疗老年性白内障患者的效果。方法:回顾性分析2019年12月至2022年3月该院收治的374例老年性白内障患者的临床资料,按照治疗方法不同将其分为观察组和对照组各187例。两组均行透明角膜隧道式主切口超声乳化白内障吸除术治疗,对照组切口长度为3.0 mm,观察组切口长度为2.6 mm。比较两组术前和术后3个月眼压、裸眼视力、最佳矫正视力(BCVA)水平,角膜散光度、角膜敏感度、角膜表面不对称指数(SAI)和泪膜功能指标[泪膜破裂时间(BUT)、泪液分泌试验(Sit)]水平,以及并发症发生率。结果:术后3个月,观察组眼压、BCVA水平均低于对照组,裸眼视力水平高于对照组,差异有统计学意义(P<0.05);两组角膜散光度均高于术前,但观察组低于对照组,差异有统计学意义(P<0.05);两组BUT、Sit水平均低于术前,但观察组高于对照组,差异有统计学意义(P<0.05);两组并发症发生率和手术前后角膜敏感度、SAI水平比较,差异无统计学意义(P>0.05)。结论:2.6 mm透明角膜隧道式主切口超声乳化白内障吸除术治疗老年性白内障患者可降低眼压及术后角膜散光度,促进视力恢复,减轻泪膜功能损伤,效果优于3.0 mm透明角膜隧道式主切口超声乳化白内障吸除术治疗。

Objective:To compare effects of 2.6 mm and 3.0 mm clear cornea tunnel main incision phacoemulsification in treatment of senile patients with cataract.Methods:The clinical data of 374 senile patients with cataract admitted to the hospital from December 2019 to March 2022 were retrospectively analyzed.According to different treatment methods,they were divided into observation group and control group,187 cases in each group.Both groups were treated with clear corneal tunnel main incision phacoemulsification.The incision length of the control group was 3.0 mm,and that of the observation group was 2.6 mm.The intraocular pressure,the naked visual acuity,the best corrected visual acuity(BCVA),the corneal astigmatism,the corneal sensitivity,the corneal surface asymmetry index(SAI),the tear film function index[tear film breakup time(BUT),tear secretion test(Sit)],and the incidence of complications were compared between the two groups before and 3 months after the surgery.Results:3 months after the surgery,the intraocular pressure and the BCVA level in the observation group were lower than those in the control group,the naked visual acuity level was higher than that in the control group,and the differences were statistically significant(P<0.05).The corneal astigmatism of the two groups was higher than that before the surgery,but that of the observation group was lower than that of the control group,and the differences were statistically significant(P<0.05).The levels of BUT and Sit in the two groups were lower than those before the surgery,but those in the observation group were higher than those in the control group,and the differences were statistically significant(P<0.05).However,there was no significant difference in the incidence of complications,corneal sensitivity and SAI level between the two groups before and after the surgery(P>0.05).Conclusions:2.6mm clear cornea tunnel main incision phacoemulsification cataract surgery for the senile cataract patients can reduce the intraocular pressure and the postoperative corneal astigmatism,promote the visual acuity recovery,and reduce the tear film function damage.Moreover,it is superior to 3.0 mm clear cornea tunnel main incision phacoemulsification.
