【摘要】：目的评价同轴微切口白内障超声乳化术控制术中虹膜松弛综合征(intraoperative floppy iris syndrome,IFIS)的治疗效果。方法前瞻性随机对照研究。2014年10月至2016年10月服用坦索罗辛≥2周的年龄相关性白内障患者80例(80眼),随机分为2组:微切口组和标准切口组,每组40例(40眼),分别通过1.8 mm微切口和2.6 mm标准透明角膜切口行同轴超声乳化白内障吸出联合人工晶状体植入术。记录并对比两组患者术中IFIS的发生率、严重程度及手术并发症,术后1 d、1周、1个月的裸眼视力。结果术后1 d、1周、1个月的裸眼视力,微切口组分别为0.83±0.12、0.86±0.10、0.89±0.11,标准切口组分别为0.71±0.12、0.75±0.11、0.83±0.12,差异均有统计学意义(均为P0.05),微切口组裸眼视力均优于标准切口组。微切口组IFIS的发生率为60.0%,标准切口组IFIS的发生率为82.5%,差异有统计学意义(P0.05)。两组术中IFIS发生的严重程度比较差异有统计学意义(P0.05),微切口组IFIS发生的严重程度低于标准切口组。结论同轴微切口白内障超声乳化术对具有IFIS发生风险的白内障患者来说是一种安全有效的手术方式。
[Abstract]:Objective to evaluate the efficacy of coaxial microincision phacoemulsification in the control of iris relaxation syndrome (intraoperative floppy iris syndrome,IFIS). Methods A prospective and randomized controlled study was conducted. From October 2014 to October 2016, 80 patients (80 eyes) with age-related cataract were randomly divided into two groups: microincision group (n = 40) and standard incision group (n = 40). Coaxial phacoemulsification combined with intraocular lens implantation was performed through 1.8 mm microincision and 2.6 mm standard transparent corneal incision, respectively. The incidence, severity and complications of IFIS were recorded and compared between the two groups. The uncorrected visual acuity was 1 day, 1 week and 1 month after operation. Results on the 1st day, 1 week and 1 month after operation, the uncorrected visual acuity of the microincision group was 0.83 卤0.12, 0.86 卤0.10, 0.89 卤0.11, and that of the standard incision group was 0.71 卤0.12, 0.75 卤0.11, 0.83 卤0.12, the difference was statistically significant (all P 0.05). The uncorrected visual acuity of the microincision group was better than that of the standard incision group. The incidence of IFIS was 60.0% in the microincision group and 82.5% in the standard incision group, the difference was statistically significant (P 0.05). There was significant difference in the severity of IFIS between the two groups (P 0.05). The severity of IFIS in the microincision group was lower than that in the standard incision group. Conclusion phacoemulsification with coaxial microincision is a safe and effective method for cataract patients with IFIS risk.
