摘要
目的比较飞秒激光LenSAR与LenSx联合白内障囊外摘除术在老年白内障患者治疗中的效果,以期为临床完善治疗方式提供依据。方法前瞻性选取永煤集团总医院2021年4月至2023年3月期间收治的老年白内障患者96例作为研究对象,依据随机抽签法分成SAR组与Sx组,每组48例。两组均行白内障囊外摘除术,其中SAR组行飞秒激光LenSAR治疗,Sx组行飞秒激光LenSx治疗,统计对比两组围术期指标、手术前后眼压、并发症发生率。结果SAR组前囊膜切开时间、尝试对接次数、预劈核时间以及激光发射时间均少于Sx组,负压吸引眼球时间长于Sx组(P<0.05);术后两组眼压较术前均升高,且SAR组眼压升高幅度高于Sx组(P<0.05);与Sx组27.08%相比,SAR组并发症发生率(8.33%)下降(P<0.05)。结论飞秒激光LenSAR与LenSx联合白内障囊外摘除术在老年白内障患者治疗中的效果各异,其中LenSAR便于接口对接,且并发症少,而LenSx能有效控制眼压且减少总负压吸引眼球时长。
【Objective】To compare the efficacy of femtosecond laser LenSAR and LenSx combined with extracapsular cataract extraction in the treatment of elderly cataract patients,in order to provide evidence for clinical improvement of treatment.【Methods】A total of 96 elderly cataract patients admitted to Yongmei Group General Hospital from April 2021 to March 2023 were prospectively selected as research objects and divided into SAR group and Sx group according to random drawing method,with 48 cases in each group.Extracapsular cataract extraction was performed in both groups.The SAR group was treated with femtosecond laser LenSAR,and the Sx group was treated with femtosecond laser LenSx.Perioperative indexes,intraocular pressure before and after surgery,and incidence of complications were statistically compared between the two groups.【Results】The anterior capsule incision time,docking attempt times,pre-nucleus splitting time and laser emission time in SAR group were shorter than those in Sx group,and the negative pressure attracting time was longer than that in Sx group(P<0.05).After operation,IOP in both groups was higher than that before operation,and the increase of IOP in SAR group was higher than that in Sx group(P<0.05).Compared with 27.08%in Sx group,the complication rate in SAR group was significantly decreased by 8.33%(P<0.05).【Conclusion】Femtosecond laser LenSAR and LenSx combined with extracapsular cataract extraction have different effects in the treatment of elderly cataract patients.LenSAR is convenient for interface docking and has less complications,while LenSx effectively controls IOP and reduces total negative pressure attracting time.
